There are several types of hazards, and hazards are divided into several categories

Category 2.

The first type of hazard refers to the energy that exists in the production process and may be accidentally released, including various energy, energy carriers or hazardous substances in the production process.

The first type of hazard determines the severity of the consequences of an accident, and the more energy it has, the more serious the consequences of an accident.

The second type of hazard refers to the factors that lead to the destruction or failure of energy or hazardous substance restraint or restriction measures, and in a broad sense, it includes factors such as material failure, human error, poor environment, and management defects.

The second type of hazard determines the likelihood of an accident, and the more frequent it occurs, the more likely it is to occur.

Legal Analysis: Hazards in industrial production processes are generally divided into seven categories:

1) Chemicals: toxic, flammable, explosive, corrosive and other dangerous goods;

2) Radiation: radioactive sources, radiation devices, and electromagnetic radiation devices, etc.;

3) Biological factors: biological factors such as animals, plants, microorganisms (infectious disease pathogens, etc.) that endanger the survival of individuals or groups;

4) Special equipment: elevators, lifting machinery, boilers, pressure vessels (including gas cylinders), pressure pipelines, passenger ropeways, large amusement facilities, special motor vehicles in the field (factory);

Legal Analysis]: According to the role of hazards in the occurrence and development of accidents, they are divided into: (1) The first category of hazards:

Accidental release of energy may occur. (2) Category 2 hazards: various factors that lead to the destruction or failure of energy or hazardous substance restraint or restriction measures, and accurately identify the two types of hazards.

A hazard is a root cause or state factor that may cause injury or illness to a person, damage to material property, damage to the work environment, or a combination of these conditions. Injury and damage to health, property damage, or other losses**. Note:

Hazards include unsafe conditions, unsafe behaviors, and deficiencies in safety management. An unsafe state is an unsafe physical, material, and environmental condition that enables an incident to occur. Unsafe behavior is the behavior that violates safety rules or safety principles and makes an incident possible or likely.

Safety management deficiencies are deficiencies in the performance of safety production management functions by managers.

A hazard should consist of three elements: the potential hazard, the conditions for its existence, and the trigger. The potential danger of a hazard source refers to the degree of harm or loss that may be caused by an accident once the accident is triggered, or the intensity of energy that may be released by the hazard source or the mass of the hazard substance.

The conditions for the existence of a hazard refer to the physical, chemical, and constrained states in which the hazard source is located. For example, the pressure, temperature, chemical stability of the substance, the robustness of the pressure vessel, the surrounding environmental obstacles, etc. Although the trigger is not an intrinsic attribute of the hazard, it is the external cause of the transformation of the hazard into an accident, and each type of hazard has a corresponding sensitive trigger.

For example, for flammable and explosive substances, heat energy is its sensitive trigger, and for pressure vessels, the pressure rise is its sensitive trigger. Therefore, a certain source of danger is always associated with the corresponding trigger. Under the action of triggers, the source of danger is transformed into a dangerous state, which in turn is transformed into an accident.

Legal basis]: Product Quality Law of the People's Republic of China Article 28 Fragile, flammable, explosive, toxic, corrosive, radioactive and other dangerous goods, as well as products that cannot be inverted during storage and transportation and other products with special requirements, their packaging quality must meet the corresponding requirements, and warning signs or Chinese warning instructions shall be made in accordance with relevant national regulations, indicating the precautions for storage and transportation.
