Basic knowledge of safe production

I. Safety production and safety production management

(1) Safety in production

Safety in production refers to making the production process conform to the material conditions and working order, preventing production accidents such as personal injury and property loss, eliminating or controlling dangerous and harmful factors, and ensuring personal safety and health, no damage to equipment and facilities, and no damage to the environment.

(2) Safety production management

Safety production management is an important part of management science and a branch of safety science. The so-called safety production management is aimed at the safety problems in people's production process, using effective resources, giving full play to people's wisdom, and making decisions, planning, organizing, controlling and other related activities through people's efforts, so as to realize the harmony between people and machinery, equipment, materials and environment in the production process and achieve the goal of safety production.

The goal of safety production management is to reduce and control hazards, reduce and control accidents, and try to avoid personal injury, property loss, environmental pollution and other losses caused by accidents in the production process. Safety production management includes legal management, administrative management, supervision and inspection, technical management, equipment and facilities management, working environment and conditions management, etc.

The basic object of safety production management is the employees of the enterprise, involving all personnel, equipment and facilities, materials, environment, finance, information and other aspects in the enterprise. The contents of safety production management include: safety production management organization and personnel, safety production responsibility system, safety production management rules and regulations, safety production planning, safety training and education, safety production files, etc.

Second, accidents, accidents, dangers, hazards and major hazards

(1) accident

Modern Chinese Dictionary defines "accident" as an unexpected loss or disaster in production and work.

In some guidance documents formulated by the International Labour Organization, such as the Code of Practice for Recording and Notifying Occupational Accidents and Occupational Diseases, occupational accidents are defined as "incidents that result in fatal or non-fatal occupational injuries caused by work or in the course of work." There are many ways to classify accidents in China.

According to the cause of the accident, according to the Classification Standard for Casualty Accidents of Enterprise Employees (GB 6441-KLOC-0/986), industrial accidents are divided into 20 categories, namely, object strike, vehicle injury, mechanical injury, lifting injury, electric shock, drowning, burning, fire, falling from a height, collapse, roof caving and flooding. The Regulations on the Reporting, Investigation and Handling of Production Safety Accidents (the State Council Decree No.493) defines "production safety accidents" as events that cause large-scale personal injuries or direct economic losses in production and business activities. According to the casualties or direct economic losses caused by production safety accidents, accidents are generally divided into the following grades:

1. Particularly serious accidents refer to accidents that cause stillbirth of more than 30 people, or 1000 people with serious injuries (including acute industrial poisoning, the same below), or direct economic losses of more than10 billion yuan;

2. A major accident refers to a major fatal accident with more than 10 and less than 30 people, or a serious injury accident with more than 50 people 10, or an accident with a direct economic loss of more than 50 million yuan 10 billion yuan;

3. A major accident refers to an accident that causes more than 3 people 10 to die, or more than 10 to seriously injure less than 50 people, or the direct economic loss10 to 50 million yuan;

4. A general accident refers to an accident that causes less than 3 deaths, or 10 serious injuries, or direct economic losses of less than 10 million yuan.

(2) Potential accidents

Order 16 issued by the State Administration of Work Safety defines "hidden danger of production safety accidents" as: "The production and business operation entities violate the provisions of laws, regulations, rules, standards, procedures and safety production management systems, or because of other factors, there are dangerous conditions of things that may lead to accidents, unsafe behaviors of people and management defects in production and business operation activities."

Accidents are divided into general accidents and major accidents. General accident hidden danger refers to the hidden danger that is less harmful and difficult to rectify, and can be rectified and eliminated immediately after being discovered. Major accident hidden danger refers to the hidden danger that is harmful and difficult to rectify, and should be completely or partially stopped, and can only be eliminated after a certain period of rectification, or the hidden danger that is difficult to eliminate by the production and business operation entity itself due to external factors.

(5) Hazard sources

From the perspective of safe production, hazard source refers to the source or state that may cause personal injury, disease, property loss, work environment damage or other losses.

According to the role of hazards in the development of accidents, hazards are generally divided into two categories, namely, the first category of hazards and the second category of hazards.

The first category of hazards refers to the energy that may be released accidentally in the production process, including various energy sources, energy carriers or dangerous substances in the production process. The first kind of danger determines the severity of the accident consequences. The greater its energy, the more serious the consequences of the accident.

The second type of hazard source refers to various factors that lead to the destruction or failure of energy or harmful substances restraint or restriction measures. Broadly speaking, it includes material failure, human error, bad environment, management defects and other factors. The second kind of danger determines the possibility of accidents. The more frequent it occurs, the greater the possibility of an accident.

Basic knowledge of safe production

Safety production inspection and hidden danger investigation and management

A, production safety inspection

Safety production inspection is an important part of safety production management of production and business units, and its work focuses on finding loopholes and dead ends in safety production management, checking whether the safety protection facilities and working environment at the production site are unsafe, whether the behavior of on-site operators conforms to safety specifications, and whether the operation of equipment and systems conforms to the requirements of on-site regulations. Through safety inspection, the management loopholes are constantly blocked, the working environment is improved, the behavior of operators is standardized, the safe and reliable operation of equipment and systems is ensured, and the purpose of safe production is realized.

(a) the types of production safety inspection

There are many classification methods for safety production inspection, which are customarily divided into the following six types.

1. Regular safety inspection

Regular production safety inspections are generally carried out in a planned, organized and purposeful manner, and are generally organized and implemented by production and business units. The inspection period shall be determined according to the scale, nature, regional climate and geographical environment of the production and business operation entity. Regular safety inspection generally has the characteristics of large-scale organization, wide inspection scope and depth, and timely finding and solving problems. Regular safety inspection is generally combined with major hazard assessment and current safety assessment.

2. Regular production safety inspection

Regular safety inspection is the daily inspection organized by the safety management department, workshop, team or post of the production and business operation entity. Generally speaking, it includes team inspection, in-class inspection and special inspection.

Handover inspection refers to the inspection of the working environment of the post and the safe operation of the equipment and systems under its jurisdiction before handover. The handover personnel should explain to the successor that the successor should foresee the possible problems and emergency measures in the work according to his own inspection and the replacement of handover personnel.

Entry inspection includes the safety inspection of post operators in the process of work, as well as the patrol or spot check of operations by leaders of production and business units, safety production management departments and workshop team leaders or safety supervisors.

Special inspection is a measure to strengthen monitoring and operation in view of abnormal conditions of equipment and systems. Generally speaking, measures are formulated by engineers and technicians and implemented by post operators.

Generally speaking, the inspection route, inspection items and inspection standards should be formulated for shift inspection and post self-inspection in class, and a special inspection record book should be established. Record the problems found in the regular post inspection in the record book, and report them step by step through the information system and telephone in time. Generally speaking, in the case of endangering personal and equipment safety, post operators should take emergency measures in time according to operating procedures and emergency measures, without asking for instructions, and report immediately after disposal. Some production and business units, such as chemical units, have a practice that post operators only need to report emergency situations that endanger personal and equipment safety, and do not need on-site disposal.

3. Seasonality and safety inspection before and after holidays

Unified organization by the production and business units, inspection content and scope according to seasonal changes, in accordance with the law, the hidden dangers prone to accidents, focusing on inspection. Such as anti-freezing and heat preservation in winter, fire prevention and gas poisoning prevention, heatstroke prevention and cooling, flood control and lightning protection in summer, etc. Accidents are prone to occur around holidays (especially major festivals, such as New Year's Day, Spring Festival, Labor Day and National Day). Therefore, targeted safety inspections should be carried out before and after holidays.

4. Professional (project) safety production inspection

Professional (item) safety production inspection is a single qualitative or quantitative inspection of a professional (item) problem or universal safety problem existing in construction (production). For example, the management or supervision of the equipment, facilities and environmental conditions in use in the workplace is a professional (item) safety inspection. Professional (item) inspection has strong pertinence and high professional requirements, and is used to check difficult projects.

5. Comprehensive inspection of production safety

The comprehensive inspection of production safety is generally organized by the competent department at a higher level or the department responsible for the supervision and administration of production safety of the local government to conduct safety inspection on the production and business operation units.

6. Workers' representatives shall inspect the safety in production irregularly.

According to the relevant provisions of the Trade Union Law and the Law on Work Safety, the trade union of the production and business operation entity shall regularly or irregularly organize workers' representatives to conduct safety inspections. Focus on checking the implementation of national safety production policies and regulations, the implementation of personnel safety production responsibility system and rules and regulations at all levels, the protection of employees' safety production rights, and the safety status of production sites.

(2) Safety inspection of internal customers

The contents of safety production inspection include: software system and hardware system.

The software system is mainly to check ideas, consciousness, system, management, accident handling and hidden dangers rectification.

The hardware system mainly checks production equipment, auxiliary facilities, safety facilities and working environment.

The specific content of safety production inspection should be determined in line with the principle of highlighting key points. Inspection should be strengthened on production systems, components, devices and equipment that are dangerous, prone to accidents and have great hidden dangers.

(3) Safety production inspection methods

1. General inspection

Routine inspection is a common inspection method. Usually, as the main body of inspection work, safety management personnel go to the site of the workplace to conduct qualitative inspection on workers' behavior, environmental conditions of the workplace, production equipment and facilities by inducing or assisting some simple tools and instruments. In this way, the safety inspector can find the unsafe hidden dangers on the site in time and take measures to eliminate these hidden dangers, thus correcting the unsafe behavior of the construction personnel.

Routine inspection mainly depends on the experience and ability of safety inspectors, and the inspection results are directly affected by the personal quality of safety inspectors.

2. Safety checklist method

In order to standardize the safety inspection work and minimize the influence of personal behavior on the inspection results, the safety checklist method is often used.

The safety checklist is usually discussed and formulated by the working group. Safety checklist generally includes inspection items, inspection contents, inspection standards, inspection results and evaluation.

The preparation of the safety checklist should be based on the relevant national laws and regulations, the current effective standards, regulations and management systems of production and business units, relevant accident lessons, the safety management culture and concept of production and business units, anti-accident technical measures and safety measures plans, seasonal, geographical and climatic characteristics, etc. Many industries in China have compiled and implemented safety inspection standards suitable for their own characteristics, such as construction, electricity, machinery, coal and so on.

3. Instrument detection and data analysis methods

Some production and business units have a system design for online monitoring and recording the operation data of equipment and systems. We can draw a conclusion by analyzing the changing trend of the data. For machines, equipment and systems without online data detection system, quantitative inspection and measurement can only be carried out through instrument detection.

(four) the working procedures of production safety inspection

(1) interview. Check the implementation of safety awareness and rules and regulations by talking with relevant personnel.

(2) access to documents and records. Check whether the design documents, operating procedures, safety measures, responsibility system and operating procedures are complete and effective; Consult the corresponding records to judge whether the above documents are executed.

(3) Field observation. Observe the production equipment, safety protection facilities, working environment and personnel operation at the work site. Look for unsafe factors, hidden dangers and accident signs.

(4) Instrument measurement. Use certain testing instruments and equipment to measure the facilities, equipment, equipment conditions and working environment conditions in use and find hidden dangers.

3. Comprehensive analysis

After on-site inspection and data analysis, inspectors shall make a comprehensive analysis of the inspection situation and put forward inspection conclusions and opinions. Generally speaking, for all kinds of safety inspections organized by production and business units themselves, the safety management department shall, jointly with relevant departments, make a comprehensive analysis of the inspection results; The safety inspection organized by the competent department at a higher level or the department responsible for the supervision and administration of production safety of the local government shall draw inspection opinions or conclusions through unified research.

(five) put forward the requirements of political rectification.

In view of the problems found in the inspection, according to the different nature of the problems, measures such as immediate rectification and rectification within a time limit are put forward. The safety inspection organized by the production and business operation entities shall be organized and implemented by the safety management department in conjunction with relevant departments, and the rectification measures shall be implemented in a planned way. For the safety inspection organized by the superior competent department or the department responsible for the supervision and administration of production safety of the local government, the inspection team shall put forward a written rectification request, and the production and business operation entity shall formulate a rectification plan.

(VI) Implementation of rectification.

For the problems and hidden dangers found in safety inspection, production and business units should draw inferences from the height of management, formulate rectification plans, and actively implement rectification.

(VII) Information feedback and continuous improvement

The safety inspection organized by the production and business operation entities shall be accepted by relevant personnel after the completion of the rectification plan. After the completion of the safety inspection and rectification measures organized by the superior competent department or the department responsible for the supervision and administration of production safety of the local government, it shall report the rectification or completion in time and apply for review or acceptance.
