How to identify major hazards, and how to distinguish between important hazards and major hazards?

Then, according to the relevant annexes "Allowable Risk Standards" and "Classification Methods for Major Hazard Sources", the grade of major hazard sources can be determined. Well, you have to be a professional, you have to be a registered safety engineer or a safety evaluator.

This is easy to recognize. Find the source of the hazard and see what the impact is. Hit the score, and then set the corresponding treatment method, and you're good to go.

One minute to read the identification of major hazard sources of hazardous chemicals.

It is to teach employees to know what dangers exist in their daily work, so as to achieve the effect of paying attention to people's thoughts and preventing them in advance before accidents

As one of the measures to prevent major accidents, the safety management of major hazards has attracted more and more attention from the society and has become an important task of safety management in modern large and medium-sized chemical enterprises. Major hazards are latent before they are triggered, and are often not recognized and taken seriously, so a certain approach is required. More》 As one of the measures to prevent major accidents, the safety management of major hazards has attracted more and more attention from the society and has become an important task of safety management in modern large and medium-sized chemical enterprises.

Major hazards are latent before they are triggered, and are often not recognized and taken seriously, so they need to be identified through certain methods.

Major sources of danger can be understood as more than a certain amount of hazards, different industries have different regulations, places and facilities in accordance with the State Administration of Work Safety issued by the "Guiding Opinions on the Supervision and Management of Major Sources of Hazards" (Safety Supervision Coordination Zi [2004] No. 56)" document provisions for identification.

Hazardous chemicals are identified according to GB18218-2009 Major Hazard Sources of Hazardous Chemicals.

Standard identification: Major hazard sources of hazardous chemicals refer to the long-term or temporary production, processing, use or storage of hazardous chemicals.

Hazard Identification:

The first step in preventing a major industrial accident is to identify or identify high-hazard industrial facilities (hazards). On the basis of the toxicity, combustion, and characteristics of the substance, the competent authorities and authoritative institutions shall formulate the standards for hazardous substances and their critical quantities. Hazardous substances and their critical mass standards can be used to determine which are potential sources of danger that could cause an accident.

Article 7 of the Interim Provisions on the Supervision and Administration of Major Hazard Sources of Hazardous Chemicals stipulates that a hazardous chemicals unit shall, in accordance with the standard of "Identification of Major Hazard Sources of Hazardous Chemicals", identify major hazard sources in the production, operation, storage and use devices, facilities or places of hazardous chemicals of its own unit, and record the identification process and results.

The above content reference: Encyclopedia - Major Sources of Danger.

1. The concept is different.

A major hazard source is an international concept that refers to a unit in which hazardous substances are produced, processed, handled, used or stored on a permanent or temporary basis, and the quantity of hazardous substances is equal to or exceeds a critical amount. The unit is divided into production unit and storage unit, the production unit is judged according to the shut-off valve, and the storage unit is judged and classified according to the fire embankment.

Important hazards are constituted after reaching a certain value after the hazard identification and evaluation is carried out, and it is not a formal concept.

2. Different grading.

The major hazard source is the sum of the ratio of the actual existence (**) of various hazardous chemicals in the unit and the critical quantity specified in the "Identification of Major Hazard Sources of Hazardous Chemicals" (GB18218), and the ratio after correction coefficient correction R as the grading index.

3. Different classifications.

There are seven categories of major hazards. storage tank areas for flammable, explosive and toxic substances; Reservoir areas for flammable, explosive and toxic substances, such as gunpowder, ammunition, toxic substances, and flammable and explosive materials; Production sites with fire, **, poisoning hazards; Hazardous (structure) buildings of enterprises; Pressure pipelines, including industrial pipelines, public pipelines, and long-distance pipelines; boilers, including steam boilers and hot water boilers; Pressure vessels.

The difference between important hazards and major hazards] major hazards is a national standard concept; Important hazard sources are the importance classification of enterprises or units to their own hazards, which is not a formal concept.

Major Hazard Sources] According to the definition of "Identification of Major Hazard Sources of Hazardous Chemicals" (GB18218-2009): refers to the long-term or temporary production, handling, use or storage of dangerous goods, and the quantity of dangerous goods is equal to or exceeds the critical amount. A unit refers to a (set) production device, facility or place, or several (sets) of production equipment, facilities or places that belong to the same production and business operation unit and the edge distance is less than 500m.

Sorry for interrupting, but what was said upstairs about the caliber of construction works. I would like to add the content of major sources of risk in the context of the environment and environmental protection. Important hazards and major hazards are mainly classified by the critical value of risk substances and are related to sensitive receptors in the surrounding environment.

When there are many varieties of hazardous chemicals in the unit, they are calculated according to equation (1), and if equation (1) is satisfied, they are designated as major hazards

q1/q1+q2/q2+…+qn/qn≧1………1）

where: q1, q2,..., qn——— the actual amount of each hazardous chemical, in tons (t);

q1，q2，…, qn——— the critical amount corresponding to each hazardous chemical, in tons (t).

For details, please refer to GB18218-2009.

There is no such thing as a 'significant hazard', nor is there a standard definition of 'significant hazard' and 'significant hazard'.

Only 'sub-projects with greater risk' and 'sub-projects with greater risk exceeding a certain scale' are referred to the Notice of the Ministry of Housing and Urban-Rural Development on Printing and Distributing the Measures for the Safety Management of Sub-projects with Greater Risks, Jianzhi [2009] No. 87. Article in these measures refers to the construction of the construction project in the process of construction, may lead to the death of workers or cause major adverse social impact of the sub-project.

The more dangerous sub-projects are shown in annex I. For sub-projects that exceed a certain scale and are more dangerous, see annex II.

What is a major source of danger? Star Awareness Project

Answer: Major sources of hazard are specified in the Work Safety Law, which refers to the production, handling, use or storage of dangerous goods in long-term or temporary work sites, and the number of dangerous goods exceeds the number of parts and units, which is a major source of danger.

Units that exceed the critical amount are a major source of danger. At the same time, if people are mentally paralyzed, it is also a major source of danger.

Major hazard sources refer to units (including sites and facilities) that produce, handle, use or store dangerous goods on a long-term or temporary basis, and the quantity of dangerous goods is equal to or exceeds a critical amount.

Major hazard sources refer to units that produce, store, use and operate hazardous chemicals on a long-term or temporary basis, and the quantity of hazardous chemicals is equal to or exceeds the critical amount.

The unit is divided into production unit and storage unit, the production unit is judged according to the shut-off valve, and the storage unit is judged and classified according to the fire embankment.

Significant hazards are identified on the basis of the hazard characteristics of substances and their quantities.

Refers to the quantity specified for a certain or class of hazardous substances, if the quantity of the substance in the single-base chain ligand is equal to or exceeds the quantity, the unit is designated as a major hazard source.

Major fires, ** or poison leakage accidents that occur in industrial activities, and cause serious harm to on-site personnel or the public, or cause significant losses to property, and cause serious pollution to the environment.

Units in which hazardous substances are produced, processed, handled, used or stored on a permanent or temporary basis in quantities equal to or greater than a critical amount.
