What are the aspects of hazard identification? What are the main methods of hazard identification?

Science Encyclopedia: Hazard Identification.

Summarize various hazards and hazards to determine what are the hazards, hazards and their distribution in the enterprise.

2. Determine the content of hazards and hazards.

In order to facilitate the analysis of hazards and hazards and prevent omissions, it is advisable to analyze the hazards and hazards according to the site, plane layout, building (structure), substance, production process and equipment, auxiliary production facilities (including public works), and operating environment hazards, and register them in a list.

Determine the mode of injury (hazard).

3. The way of injury (harm) refers to the way that causes harm to the human body and causes damage to human health. For example, extrusion, occlusion, collision, shearing, etc. of mechanical injuries (hazards), poisoning target organs, abnormal physiological functions, physiological structure damage forms (e.g., mucosal erosion, autonomic nerve disorders, asphyxia, etc.), dust retention in the alveoli, pulmonary tissue fibrosis, lung tissue carcinogenesis, etc.

The method of hazard identification should be mainly to see, well, look and hear. And then in terms of these methods, we should stay away from the source of danger.

There are many methods for hazard identification, and the basic methods are: interrogation and conversation, on-site observation, access to relevant DU records, obtaining external information, work task analysis, safety checklist, hazard and operability research, event tree analysis, and fault tree analysis. of these.

Methods have their own scope of application or limitations, and the use of one method in the process of identifying hazards often cannot fully identify the hazards that exist, and two or more methods can be used comprehensively.

We will find that it is very troublesome to go to the hospital after getting sick, queuing **, queuing for checks, queuing**, and so on. Edition.

The illness is not very serious, but it is very bad. It's like after a safety accident occurs at the production site, no matter how big or small the accident is, but it is very difficult to deal with, sometimes like a firefighter, tired of "extinguishing the fire", right?

Don't worry, today we will talk about how to avoid accidents and how to identify potential dangers around you!

Summary. Hello! The main contents of hazard identification are as follows:

Hazard identification is the process of identifying hazards and determining their characteristics. Hazard identification is mainly to identify the hazard source, judge its nature, and prevent the possible harm and impact in advance to ensure the safety and stability of production.

Major hazards are divided into two major hazards: production sites and storage areas.

Production and business operation entities violate the provisions of production safety laws, regulations, rules, standards, procedures and safety production systems, or due to other factors in production and business activities that may lead to accidents, unsafe human behaviors and management defects.

The source of danger itself is a "root cause" in which the potential cause of an accident may lead to injury or illness, or a state in which the subject may induce injury or illness. For example, a gas cylinder containing acetylene has burst.

The source of danger is acetylene, which is the source of the accident; The hidden danger of the accident is the rupture of the acetylene bottle, which leads to the "state" of the accident.

What are the main contents of hazard identification?

Hello, it's a pleasure for me to answer this question for you, it may take me a few minutes to sort out the information and type, please be patient for a few minutes......

Hello! The main content of hazard identification is as follows: Hazard demolition and simplified source identification is the process of identifying hazard sources and determining their characteristics.

Hazard identification is mainly to identify the hazard source, judge its nature, and prevent the possible harm and impact in advance to ensure the safety and stability of production. Major hazards are divided into two major hazards: production sites and storage areas. Production and business operation entities violate the provisions of laws, regulations, rules, standards, procedures and safety production systems, or due to other factors in production and business activities that may lead to dangerous conditions, unsafe behaviors and management defects in production and business activities.

The source of danger itself is a "root cause" in which the potential cause of an accident may lead to injury or illness, or a state in which the subject may induce injury or illness. For example, a gas cylinder containing acetylene has burst.

The source of danger is acetylene, which is the source of the accident; The hidden danger of the accident is the rupture of the acetylene bottle, which leads to the "state" of the accident. Hello, the above is the Royal Sparrow, you can refer to it, I hope it will help you I wish you a happy life! 

The scope of hazard identification includes the following:

1. The company's in-use system, scrap system and the activities of colleagues in the workplace.

2. The in-use systems and scrapping systems of first-class merchants and service manufacturers in the workplace and the activities of their employees in the company's workplace.

3. The company's past activities and services.

4. Construction of new production line and improvement of original production line.

5. The equipment is reused after being out of service for a long time.

6. Modification of operation steps.

Hazard identification is the process of identifying hazards and determining their characteristics. Hazard identification is mainly to identify the hazard source, judge its nature, and prevent the possible harm and impact in advance to ensure the safety and stability of production.

Hazard identification procedures

1. Hazard investigation.

Before conducting a hazard investigation, it should be determined whether the system to be analyzed is for the entire enterprise or a workshop or a production process, and then the system to be analyzed is investigated, including the production process equipment and materials, the operating environment, the operation of the wild spring rock, the accident situation, and the safety protection situation.

2. Definition of hazardous areas.

That is, to delineate the scope of the hazard source point. The system should be divided, and subsystems can be divided by equipment, production equipment and facilities or operating units. Then, the hazard source points in each subsystem are analyzed, and the equipment, containers, etc., which generate energy or have energy and produce the accumulation of hazardous substances are generally used as hazard source points.

Then, the hazard source point is the core, and the protection range is the danger area.

3. Analysis of existing conditions and triggers.

The analysis of existing conditions and triggers is an important part of hazard identification. The analysis of existing conditions includes storage conditions (such as stacking methods, other items, ventilation, etc.), physical state parameters (such as temperature, pressure, etc.), equipment conditions (such as equipment integrity, equipment defects, maintenance, etc.), protective conditions (such as protective measures, fault handling measures, safety signs, etc.), operating conditions (such as operation technology level, operation error rate, etc.), and management conditions.

4. Potential risk analysis.

The hazard is transformed into an accident, which is manifested by the release of energy and hazardous substances, so the potential danger of a hazard source can be measured by the intensity of the energy and the amount of the hazardous substance. Energy includes electrical energy, mechanical energy, chemical energy, nuclear energy, etc. Hazardous substances mainly include burning ** hazardous substances and toxic and harmful hazardous substances.

5. Hazard classification level.

The classification of hazards is generally divided according to the probability and severity of the hazard source being transformed into an accident under the action of triggers, and can also be divided according to individual indicators. According to the probability of accidents, they can be divided into very easy to occur, easy to occur, relatively easy to occur, not easy to occur, difficult to occur, and extremely difficult to occur. According to the severity of the accident, it can be divided into negligible, critical, dangerous, and destructive.
