Model essay 202 1 (a set of 6 articles) on the annual work summary of safety officers

Time flies, and it's the end of the year, and I'm about to start my work for the next year. Must be a lot of feelings. Have you finished writing the year-end summary? The following is the model essay 2021(a collection of 6 articles) compiled by me for your reference only. Welcome to read this article.

Part I: Annual Work Summary of Safety Officers Model essay 202 1 Since I started working as a "full-time safety officer" in 20021,I have always regarded "being a qualified safety officer" as the pursuit goal of my current work. Since shouldering this heavy responsibility, I have always kept a clear head, treated my work with a diligent and down-to-earth attitude, worked in my present post for one year, strictly followed the safety work objectives set at the beginning of each year, fully implemented the safety policy of "safety first, prevention first and comprehensive management", and strengthened the management of safety production.

With the trust and support of the relevant leaders of the project department, I cherish this security role very much and devote myself to my work with a positive attitude. I have a great sense of accomplishment in my work in the past year.

Personal work in recent years is summarized as follows:

1. Take "being a qualified safety officer" as the working motivation, love the country and the party ideologically, think about the interests of the bureau everywhere in action, make positive progress, assist the leaders in charge to conscientiously implement the responsibility system for production safety, strengthen the publicity and communication of laws and regulations related to production safety, carry out safety training in a down-to-earth manner, firmly fulfill the commitment of the responsibility book for safety objectives, and ensure the smooth realization of the three-level safety production objectives of the project department. In management, we are loyal to our duties, strict in safety awareness and professional ethics. Through safety day activities and regular safety meetings, we analyze the signs of weak safety awareness, lack of experience, fear of trouble and inertia, and nip them in the bud. Learn safety skills and knowledge together with project department employees, study and analyze accident cases, summarize accident lessons, and continuously improve business level. As long as it is conducive to the development of the project department and safe production, take the lead.

2. Under the correct leadership of the competent leader, carefully supervise the safety function of equipment and personnel in the construction area. In the planning, arrangement, inspection, summary and assessment of safety production, we should put an end to habitual violations, resolutely pay close attention to unlicensed operation, and resolutely punish other safety violations, so that they can master the major hidden dangers and weak links that threaten safety production.

3, through the daily safety patrol in a timely manner to understand the situation of production safety. Go to the construction site every day to check the safety in production, conduct a comprehensive inspection of all areas under the jurisdiction of the project department four times a month, organize relevant personnel to check special equipment and vehicles, implement and urge relevant departments and ZuoYeDui to carry out repairs and maintenance, and make all equipment run healthily and stably.

4. Actively take the lead in "safety assessment", do a good job in "spring", "summer", "autumn" and "winter" safety inspection activities, do a good job in the preparation and exercise of emergency plans, and do a good job in the annual safety month activities. In these activities, they carried out seriously and solidly with strict, meticulous and practical requirements, and achieved good results, which was praised by superiors.

5. Seriously perform their duties, strictly control the safety during the implementation of the "safety evaluation" work, organize relevant personnel to do a good job of inspection and evaluation, strictly implement the system, and further improve the safety management level, so as to greatly improve the safety situation of the project department.

6. In recent years, safety work has been carried out around the "safety standardization" management system, mainly from three aspects: occupational health, safety and environmental protection. When I first started working in safety, my work experience was not very rich, and there were always some problems in my work. In order to be familiar with all kinds of business in a short time, I constantly learn safety knowledge through various channels to enrich myself, and gradually become a qualified safety officer through the work of "safety standardization".

7. Take root in the front line of production and extensively absorb the experience of all parties. At work, I hope I can have more opportunities to join the production line, because it can give me enough growth nutrients. Only by truly taking root in the production line can we have a deeper understanding of occupational health, safety and environmental protection and promote my better work; Communicate with workers in the front line of production, and extensively absorb experiences from all sides, so as to find problems in time, expand their working ideas, and truly realize the coordinated development of occupational health and safety and the environment.

8, correctly handle interpersonal relationships. In daily work, there are many exchanges with superiors, colleagues and construction personnel, so problems of one kind or another may occur in the course of daily work, and friction is inevitable. This requires me to straighten my mind and actively avoid such problems. Young people are easy to be impetuous at work, and they are likely to be thoughtless when dealing with problems, and they will do irrational things on impulse, which I try to avoid at work. Correctly handle the relationship with other colleagues, and actively and optimistically help colleagues in trouble.

The second part: the annual work summary model essay, Safety Officer 202 1 "Being a qualified safety officer" is the pursuit goal of my current work. Since shouldering the heavy responsibility of safety officer, I have always kept a clear head, treated my work with a diligent and down-to-earth attitude, worked in my present post for one year, strictly followed the work objectives set at the beginning of the year, fully implemented the policy of "safety first, prevention first", and strengthened the management of safety production.

202 1 under the correct leadership of the director, with the trust and support of the relevant leaders of the rural power company, I cherish this security role very much and put myself into my work with a positive attitude. This year's work is a very fulfilling year. Now I will sum up my work in the past year:

1. Take "being a qualified safety officer" as the working motivation, pay attention to patriotism ideologically, take the interests of the bureau as the priority and be proactive in action, assist the director to seriously implement the responsibility system for production safety, strengthen the laws, decisions and regulations related to production safety, do a solid job in safety training, firmly fulfill the commitment of the safety responsibility book, and strive to achieve the company's three-level safety production goal. In management, they are loyal to their duties, have strict safety awareness and professional ethics, learn safety skills and knowledge together through safety day activities and production operation analysis meetings, learn and analyze accident lessons, and constantly improve their business level, as long as it is conducive to enterprise development and safe production.

2. Under the correct leadership of the supervisor, carefully supervise the functions of the equipment and personnel under their jurisdiction. In the planning, arrangement, inspection, summary and assessment of production work, put an end to habitual violations, resolutely kill without a ticket, and resolutely punish the protector for quitting the operation, so that you can master the operation of the equipment in charge and the major hidden dangers and weak links that threaten safety in production.

3, under the personal guidance and work arrangement of rural power equipment group, timely understand the situation of safe production. I can go to the village to check the safety in production every month, conduct four night patrols and special patrols on the equipment every month, classify the defects of the equipment, implement and urge the equipment group to improve. So that the equipment can run healthily and stably. Able to complete the tasks assigned by superior leaders in time.

4. Actively take the lead in "safety evaluation", "creating a first-class power supply enterprise", doing safety inspection activities in "spring", "summer", "autumn" and "winter", and carrying out these activities seriously with strict, detailed and practical requirements, which has achieved good results and been praised by superiors.

5. Seriously perform their duties, strictly control the safety during the implementation of "Safety Assessment", urge electricians to do a good job of inspection and evaluation, and * * * find out more than 0/0000 defects. At present, the rectification of xx defects has been completed, which further improves the health level of equipment and greatly improves the safe use of electricity in the whole town.

Although 202 1 has made some achievements in safety management, there is still a certain gap from the requirements of leaders. In the new year, I will pay more attention to safety management in strict accordance with the requirements and instructions of superior leaders, make greater contributions to the safe use of electricity throughout the year, and ensure the safety of people's lives and property and the normal use of electricity.

Chapter III: Annual Work Summary of Safety Officers Model essay 202 1 Everything, system first, safety first, quality first, which is the starting point of all my work this year. Plan-oriented, manage the whole process, and annotate the results with benefits. I am responsible for construction management, safety production, quality control, planning statistics, maintenance return visit and other aspects of xx. The following is a summary of my personal work in the past year:

First, establish rules and regulations and clarify responsibilities.

Soon after the company's operation, with the support of the leaders, the department arranged the work for the whole year. At the professional meeting, the company leaders signed a safety responsibility form with President xx to implement the safety responsibility. Various rules and regulations have been established and improved. With reference to the Project Management Manual, Safety Responsibility Form, Quality Excellence and other materials, our department has successively formulated and promulgated xx management regulations such as Safety Inspection System, standardized the management of organs and projects, fundamentally straightened out the relationship between the responsibilities and rights of the company and the project management department, and made the company's daily construction and production work orderly.

Second, the planned construction of civilized production

Entrusted by the leader, I am responsible for the construction and production of the company. Starting from the construction scheme, under the leadership of the company team, with the cooperation and support of government departments, we have done some work on various construction projects. Adhere to the monthly safety inspection and production scheduling, assist the project to solve the problems existing in production, and always go to the construction line with quality and safety problems as soon as possible to ensure the smooth progress of production.

While grasping production, I pay great attention to the civilized construction on site. Because it is not only the image of an enterprise, but also enhances the visibility of the enterprise and creates a harmonious construction environment for the project. Therefore, in the monthly inspection and patrol, civilized construction is placed in a very important position and actively assists the project.

Three-dimensional protection of safety precautions

Adhere to the project construction inspection, xx days a month, and the safety management personnel of all departments of the company will focus on the inspection according to the reality of different stages of the project; In the third month of each quarter, organize a project construction inspection team attended by engineering, materials, finance, comprehensive and other departments to conduct a comprehensive inspection of the projects under construction focusing on safety production. The important facilities such as scaffolding, derrick, tower crane, aerial work, "three treasures and four mouths", border protection and construction electricity were inspected emphatically.

In the first xx months of this year, * * * issued xx rectification notices and proposed xx rectification measures, with a cumulative fine of xx yuan. Correct the illegal command and operation behavior in the inspection on the spot, find out the potential safety hazard, issue a rectification notice, and make rectification within a time limit. The project responded to all the questions raised by the inspection team and completed the rectification according to the requirements of the rectification notice.

In order to strengthen the unified management of safety work and realize the effective management of safety managers, it is necessary to implement a vertical management system, and holding regular safety meetings is a good way to achieve vertical management. The department has re-improved the regular meeting system of safety classes, and all safety officers hold regular meetings together on X day every month. The main content is to convey the superior documents and spirit, report the work situation and difficulties, and conduct inspections and exchanges in the project. In this way, the company can know the safety production situation of the project more timely, improve the communication between the safety officer and the safety secretary and the company, and solve the difficulties in the work of the safety officer in time. Make the company's safety work more comprehensive and effective.

Fourth, the professional training of all-staff education.

In order to speed up the development of the company, change the current situation of talent shortage, adapt to the reality of the company's production and operation, promote the in-depth development of the company's management, adapt to the constant changes in the form of construction technology, face the reality of fierce competition in the construction market, and provide space for the personal development of employees, the company will be turned into a "learning" enterprise, and all employees will be educated and trained by departments and offices, and the company will be built into a school where employees can learn and re-learn. According to the actual construction and production of the company, the project management department was organized to carry out all-staff learning activities, and successively studied the Regulations on Safety Management of Construction Projects, National Standard for Ready-mixed Concrete, Management Regulations on Acceptance of Quality and Technical Data of Completed Projects, Order of Safety Awards and Punishment, and Management Data Manual of Construction Safety Production Assurance System. Good results have been achieved. In the tense daily affairs, take time to study, take the way of going out and inviting in, learn from others' advanced experience and good practices, and improve the management level of the company.

Five, maintenance return visit to achieve a win-win situation

By the end of last year, the company had delivered xx projects to the owners. When we handed in the key, we informed the company's maintenance team of the telephone number, and repaired the problems in the use process in time, helping the owner to find ways to solve the practical problems in time, which won the praise of the owner and the competent department.

At the same time, pay three rounds of return visits to all completed project companies as planned, and repair and deal with the existing problems in time. So far, we haven't received any complaints and exposure calls from the owners.

Through the above work, we not only fulfilled our responsibilities, but also tasted the sweetness. The owner praised us as an excellent team, which laid a good foundation for our project settlement and subsequent project undertaking.

Six, excellent quality products

In order to further expand the local popularity of the branch, provide strong brand support for the operation, and emphasize the awareness of quality products, the company made clear the goal of creating excellence in engineering quality at the beginning of its establishment, loudly put forward the strategic slogan of quality products, established a quality committee according to relevant regulations, improved the internal supervision institutions and personnel, and the certificate-holding rate of quality management personnel was 100%. In the construction process, the plan was made in advance, and the process control was emphasized. The overall level of the project has been greatly improved, and no engineering quality accidents have occurred. Engineering data and construction progress are basically synchronized, and engineering entities can represent the level of the system. Xx project main body acceptance.

Seven, summarize the shortcomings and look forward to the future.

Generally speaking, this year's work, I am conscientious and loyal to my duties. Some achievements, self-evaluation "good"! But there is still a big gap from the expectations of branch leaders.

1, the overall management level of the company is not high, and the guidance, management and supervision of construction projects need to be strengthened and improved. In the future work, the company will continue to pay special attention to the authenticity and integrity of the construction management records in the construction process and the compilation of the company's characteristic construction methods while implementing the standards.

2, change ideas, improve methods, and make the work more detailed and solid.

3. The full-time safety management personnel of the joint venture team of the company are not in place, and the safety management of the production line is still in the stage of extensive management. We will continue to implement and deepen the three major measures of safety management. First, the security risks of the mortgage system. When the labor team enters the site, in addition to signing the safety liability certificate, a certain amount of safety risk of mortgage must be paid; It is everyone's responsibility to truly achieve safe production. The second is to implement the direct management system of labor security officers. Supervise the labor service team to set up full-time (part-time) safety officers, bring the safety officers into the direct management of the company's departments, and tilt the safety work center to the front line. The third is to establish and improve the safety evaluation system of operation teams, strengthen the safety awareness of front-line workers, and truly reduce safety risks from the source.

4, actively assist other departments, in accordance with the provisions of the "Building Law", and according to the requirements of the local government, to do a good job of accidental injury insurance for on-site construction personnel.

5. Strengthen personal learning and constantly enrich yourself. This year's study plan is too concentrated in time arrangement and the study effect is not very good. It is necessary to take the opportunity of taking the national first-class construction engineer examination, actively learn new knowledge and apply scientific methods to production practice in combination with regional conditions and personal reality.

Xiongguan road is like iron, and now it is one step closer to the beginning! The past years have turned a page of the calendar, summed up the history, found out the shortcomings, carried forward the strengths and created a bright future. Under the leadership of the company's leading group, I will continue to go all out, work hard and strive to make the company stronger.

Chapter IV: Summary of Safety Officer's Annual Work Model 202 1 One year will soon pass and usher in a new year. This year, I worked as a builder in the project department of xx Company, and successively as a builder and safety officer in the bridge project of xx. Briefly summarize this year's work.

First, the site construction

The success of an enterprise lies in safety, and the failure lies in accidents. Any accident is an irreparable loss to the enterprise, and it also causes irreparable pain to the family and individuals. In the early stage of construction, I cooperated with the project manager and the company safety officer to do a good job in level 3 safety education. The environment of xx highway construction is very different from that of xx bridge project. In the construction, we must teach students in accordance with their aptitude and communicate with different types of work, so that workers can really listen to their own voices. Make the site construction work more solid.

Second, the engineering safety

In this year's project construction process, we will actively face the problems and carry out accurate construction according to the drawings to ensure that there will be no slowdown and rework! Carefully investigate the potential hazards in each construction process. Communicate with the construction personnel on the construction site in time, arrange safety work according to the construction plan and ensure the smooth completion of the construction, and be diligent in your legs, hands and eyes. During the construction period, I am always nervous every day. There are no safety accidents all year round, so my nervous heart can finally be put down.

Third, in the field of data collation.

Read the compilation of construction organization design carefully, study and be familiar with the drawings in detail in advance, and get to know the whole construction process and various matters needing attention in your mind. Before the construction preparation, the preparation of the construction scheme should be close to the reality, and all kinds of information and engineering quantity confirmation information formed in the construction process should be signed and confirmed by the supervision engineer in time, so as not to affect the later measurement. During the road construction in xx this year, it was the first time in my career to participate in road construction. At first, I was a little confused. In the early stage, I carefully read the road specification materials and other preparatory work. To solve the problems and difficulties encountered in the work.

The security officer's job is also very hard. I have to run around the construction site during the day, supervise the construction progress, and review the construction according to the drawings to avoid mistakes. In the evening, I have to sort out the drawings of the day and arrange the work for the next day. At work, I always finish it on the same day and never put it off until the next day. Ensure that when the follow-up work is implemented, there is no hurry, no shortage of east and west, and the construction period will not be affected.

In the busy work, I still insist on studying and taking the second-level constructor exam, and I also read and learn some construction specification materials in my spare time. I hope to make persistent efforts and create brilliant achievements in next year's work.

Chapter 5: The year of safety officer's annual work summary model essay 202 1 202 1 is about to pass. In this year, "being a qualified safety officer" is the pursuit goal of my current work. Since shouldering the heavy responsibility of safety officer, I have always kept a clear head, treated my work diligently and practically, and worked in my present position for one year in strict accordance with the work objectives set by the company. Fully implement the policy of "safety first, prevention first" and strengthen the management of production safety. In 20021year, with the trust and support of the company's safety supervisor and related leaders, I took the post of safety officer and devoted myself to my work with a positive attitude. I feel that this year's work is very fulfilling. The work of the past year is summarized as follows:

1. Take "being a qualified safety officer" as the driving force of my work, pay attention to the people-oriented policy of "safety first, prevention first" ideologically, think about the safety interests of the company and employees everywhere in action, make positive progress, assist the company's safety officer to earnestly implement the responsibility system for safety production, actively participate in safety training and learning related to safety production laws, regulations, decisions and regulations, and attend quarterly safety production of Caopu Town Government on time. Firmly fulfill the commitment in the safety responsibility book, and strive to achieve the goal of 100% of the three-level safety education rate and qualified rate of new employees in the company. According to the different positions of new employees in practical work, pre-job education of safety technology knowledge is carried out according to the post characteristics, and the national safety production policy, enterprise production characteristics, production technology, main safety production rules and regulations, dangerous areas, safety production operation procedures, etc. are publicized. , and according to the company's production characteristics, emphasize the knowledge of fire prevention and electricity safety.

2. Carefully supervise the safety functions of the company's equipment and personnel, establish equipment ledgers for all equipment, and establish inspection records of daily work and equipment maintenance records. grasp

Equipment operation enables the equipment to run healthily and stably. Set up safety signs and warning slogans in the production work area. Regularly investigate and rectify potential safety hazards in the workplace and report to the company's safety supervisor in the form of statements. In terms of personnel, it is mainly to grasp the signs of "three violations" of weak safety awareness, weak experience and concept, fear of trouble and inertia thinking in production work, and explain them through accident cases, so that employees can learn from accidents and put an end to habitual violations. At the same time, the management of trace files such as three-level safety education roster, safety responsibility signing roster and special operations personnel registration roster has been established.

Although I have made some achievements in safety management in 20021,there is still a certain gap from the requirements of the leaders. Safety production management has only a starting point, but no end point. In the new year, I will pay more attention to safety management in strict accordance with the requirements and instructions of superior leaders, and make my own contribution to the realization of accident-free production throughout the year and the safety of life and property of the company and its employees.

Chapter VI: Annual Work Summary of Safety Officers Fan Wen2021Under the correct leadership of group companies and mining companies, our mine has always adhered to the safety production policy of "safety first, prevention first and comprehensive management", thoroughly implemented Scientific Outlook on Development, firmly established the concept of "zero harm" in safety production, consolidated the foundation, refined the responsibilities, strengthened safety supervision, deepened the investigation and management of hidden dangers, and formulated and revised a number of safety management systems in combination with the actual situation.

First, strengthen the construction of cadres' work style and conscientiously implement the responsibility system for production safety.

In the construction of safety management mechanism, it is necessary to earnestly implement the leadership responsibility of the "number one" who takes overall responsibility for safety work, the leadership responsibility of "managing production must manage safety", the business safety responsibility of business departments, the supervision responsibility of safety supervision departments, and the post responsibility of employees to abide by rules and disciplines.

According to the requirements of the superior, our mine has formulated the system of mine leaders taking classes in the well, requiring all mine leaders to take classes in the well, go deep into the fields and be close to the front line, find and solve problems encountered in production in time, and use the personnel positioning system to monitor mine leaders and managers at all levels in real time to ensure that the work of taking classes with classes is implemented.

To strengthen the system construction, the "xx Coal Mine Dynamic Safety Inspection Management Measures" and "xx Coal Mine Civilized Production Quality Standardization Assessment Measures" were issued. According to the assessment method, the safety officer reports the inspection results in shifts and reports them at the dispatching meeting the next day. In addition to the corresponding punishment for the responsible person, it is also necessary to investigate the responsibility of the unit where the responsible person belongs, the person in charge of the unit and the internal management personnel of the unit, so as to implement the responsibility system for production safety.

The second is to intensify the investigation of hidden dangers and eliminate unsafe factors.

There are three forms of mine safety inspection: follow-up inspection by mine leaders, dynamic inspection by safety personnel and joint inspection every ten days. The inspection results are summarized and entered into the intrinsic safety information system by the safety department, and the rectification is carried out according to the principle of "five determinations". Each unit arranges special personnel to conduct audit to realize closed-loop management of hidden dangers. At the same time, the security department set up a dynamic inspection team to inspect the underground workplaces from time to time to find and eliminate hidden dangers in production in time.

Third, risk identification and pre-control

At the beginning of the year, the mine manager and all employees are trained in the knowledge of intrinsic safety system, and the basic knowledge of intrinsic safety is tested in the third week of each month. Hazard identification and risk assessment were carried out for xx tasks in each production link of the mine, and xx hazards were identified, and continuous risk assessment was carried out for key safety work and high-risk tasks, and management standards and control measures for various hazards were formulated in detail, so that all hazards were controlled in advance, contact control and accident control. The control, management and implementation of major hazard sources shall be personally grasped by the leaders in charge. Through sorting out the major hazard sources, there are xx major hazard sources in our mine, and the management standard language management measures are formulated according to the actual situation.

Fourth, the comprehensive prevention and control of gas

My mine belongs to low gas mine, and no gas is found in actual mining and production, but it is still managed according to the management standard of high gas mine. All underground mining faces, wind stopping places and closed tunnels are managed in real time by monitoring and tube monitoring system, and the comprehensive gas prevention and control work is carried out by individuals, and a comprehensive gas control organization headed by the mine manager is established to regularly study and solve the law of mine gas emission and the problems existing in gas control work. At the same time, strengthen the gas detection in the mine series ventilation sites and the operation sites affected by climatic conditions, and make records and reports. There was no gas accident in this mine all year round.

The Construction of verb (abbreviation of verb) Intrinsic Security System

Under the organization and arrangement of the mine intrinsic safety committee, the intrinsic safety system operates normally. In the inspection of the mining company in the first three quarters, the intrinsic safety assessment of the mine meets the second-class standard.

The mine leaders, personnel on duty and management personnel of each unit timely input the hidden dangers found into the intrinsic safety information system. The information system monitors the hazards 24 hours a day, and according to the principle of "who checks, who rechecks, who rectifies and who goes to work", it carries out real-time monitoring and instrument monitoring on the state of hazards and the state of on-site facilities and equipment, so as to make all kinds of hazards in the mine in a controllable state and truly realize the closed-loop management of hidden dangers.

According to the "Assessment and Scoring Standard for the Construction of Intrinsic Safety System of xx Group", our mine distributes the information in the industry to all units for sorting according to the actual situation. At present, all the information in the industry is basically complete, but there is still a gap with the requirements of xx Group's intrinsic safety system construction, which needs to be further improved.

Six, the district team construction

The construction of regional teams is the basis for the safe and harmonious development of coal mining enterprises today. Our mine will always build itself into a learning team, intrinsically safe team, efficient team, harmonious team and innovative team, and strengthen the management of district teams and teams. At present, there are xx teams in our mine (xx mining units and xx outsourcing teams), with a total number of xx teams.

Seven, safety culture construction, science and technology Hinggan

Over the past year, our mine has focused on accelerating the construction of intrinsically safe mines, with the concept of "promoting safety culture, implementing safety responsibilities and adhering to safe development" and taking the safety of employees' lives and property as the fundamental starting point, vigorously publicized the importance of team building, strengthened team cohesion, and improved the safety technical level of team members by organizing a series of safety activities such as self-help and mutual rescue training and special type of work training; In addition, the team construction management system is used to realize the informatization of the team's daily work, so that employees can clearly understand the work safety situation and the work focus of the team, and can also convey the instructions and spirit of the company and the superior departments to each employee in time, which increases the efficiency of information transmission and effectively guides the regional team to organize production.

At present, our mine has adopted new technologies and equipment, such as personnel positioning system, underground mobile phone, video monitoring and anchor excavator. , improve the ability of mine science and technology safety creation, and realize mine modernization, digitalization and informatization.

Eight, leading cadres into the well.

Strictly implement the system of mine leadership shift, and implement underground succession. The mine manager is required to go into the well no less than xx times a month, and the deputy mine manager and deputy chief engineer are required to go into the well no less than xx times (except in special circumstances), and all the problems and rectification found during the shift change will be fed back to the production command center, which will summarize them and report them at the mine dispatching meeting the next day. The security department is responsible for inputting problems into the intrinsic safety information system to realize the closed-loop management of potential safety hazards.
