What aspects does security include?

Safety basically includes the following contents: national safety, campus safety, laboratory safety, personal safety, public safety, enterprise safety, production safety and construction engineering safety.

The harmony between human beings as a whole and living environment resources does not harm each other, and there are no hidden dangers and harms, which is a state of avoiding unacceptable damage risks. Safety is to control the possible damage caused by the running state of the system to human life, property and environment below an acceptable level in the process of human production.

Security has the attributes of space and time: when both space and time are available, there will be a safe state or a dangerous state; When space and time are different, there is a safe state or a dangerous state.

For example, wait for a red light at the intersection, and the red light prompts the longitudinal vehicle to stop giving way in the line within 60 seconds. During these 60 seconds, the vehicles in the stop line, the rushing vehicles and the pedestrians on the zebra crossing are all in a safe state. Parking in the driveway is the positioning of space, and 60 seconds is the time. Only when they work together can the safety state be guaranteed.

On the contrary, if a car runs a red light within 60 seconds, the spatial position changes and works at the same time as time, then it will be in a dangerous and unsafe state, leading to an accident. This is the safe or unsafe state caused by the simultaneous action of space and time.

Extended data:

Security has the attributes of space and time: when both space and time are available, there will be a safe state or a dangerous state; When space and time are different, there is a safe state or a dangerous state. What needs to be done for safety:

1. Control, prevent, eliminate and avoid accidental injuries, so as to safeguard human life safety.

Second, be vigilant and form good habits to ensure the safety of life and the smooth work.

Third, from the personal body, life, and the safety of life, and then achieve the safety of group activities, social operation, and national survival.

Its main projects are:

1. Life safety education: including clothing, food, shelter, transportation, work, exercise, first aid, nursing, disease prevention, injury prevention, antivirus, waterproof, fire prevention, wind prevention, electricity prevention and earthquake prevention.

2. Traffic safety education: Due to frequent road traffic, the prevention of accidents on the road and in the car is particularly strengthened during the project implementation.

Third, cultivate knowledge and skills such as emergency evacuation and air defense evacuation. The implementation of safety education is mainly based on teaching activities, supplemented by administrative measures. Administrative measures are to provide safe equipment and environment; Teaching pays equal attention to the cultivation of psychological attitude, habitual behavior and knowledge and skills. Its expected educational effect depends on the embodiment of the overall and grand goals of individual security, group security, social security and national security.

In theory, absolute security does not exist under unconditional conditions! Theories are all based on conditional systems-complex forms of established conditions.

Then, in a fixed stage of the intrinsically safe state, we can think that this condition is absolutely safe. If placed in a long historical state, security can only be relative.

Absolute security and relative security are dialectical relations.
