What is Hot Work?

Hot work is a process that can be a source of ignition when flammable material is present or can be a fire hazard regardless of the presence of flammable material in the workplace. Hot work refers to unconventional work other than process settings that can directly or indirectly produce open flames, such as the use of electric welding, gas welding (cutting), blowtorches, electric drills, etc. These process methods will produce open flames during use. According to the different sites and risks of hot work, hot work can be divided into: special dangerous hot work, Level 1 hot work, Level 2 hot work and Level 3 hot work.

Welding and cutting equipment require large currents, and open flames will appear during work. For workers, personal injuries such as burns and electric shocks may occur. If fire-using operations involve working at heights or entering restricted spaces, etc. Accidents such as falling from heights, poisoning and suffocation, electric shock, and damage to the working environment may also occur.

In some special areas, such as oil extraction, refining, storage, and transportation, especially crude oil, natural gas tank areas, or other chemical storage areas, hot work is strictly prohibited. However, large irrigation areas that have been in operation for many years need to be separated, or Centralized maintenance and renovation; usually the method requires emptying the oil and gas in the tank, filling it with gas protection, starting the fire ticket, and the supervisor coordinates the fire truck to supervise the operation, etc. The cost of one tank often costs 20,000 to 30,000 US dollars, and the time is short. One week, as slow as one month, or even longer; The permanent magnet assemblies manufactured by Weizhong Magnetics have the characteristics of explosion-proof, high safety, reliability and quick installation. We can provide standards or customized magnetic fastener solutions according to customer requirements.

Detailed introduction to action tasks

(1) Special dangerous hot work refers to hot work on flammable and explosive medium production equipment, storage tanks, containers and other particularly dangerous places under production operation conditions.
(2) Level 1 hot work refers to hot work carried out in flammable and explosive places.
(3) Level 2 hot work refers to hot work carried out in places with low risk of fire and explosion.

Classifications of hot work areas

In order to increase the intensity of safety management and facilitate the adoption of different control measures, the entire production area can be divided according to the risk of fire and explosion in production materials, production equipment or production units, as well as the severity of fire or explosion accidents. There are three levels of areas: Class I hot fire area, Class II hot fire area and fixed hot fire area, so that different control measures can be taken.

(1) Class I fire area. It usually means that there is a greater risk of flammability and explosion in the production area. If a fire or explosion accident occurs in this area, it will cause greater property losses and more casualties.

(2) Class II fire area. It means that there is a small fire or explosion risk in the production area. If a fire or explosion accident occurs in the area, it will only cause certain property losses and few casualties.
Class II hot fire areas can also be simply regarded as production areas outside the scope of Class I hot fire areas and fixed hot fire areas.

(3) Fixed fire area. It refers to an area with no risk of burning or explosion within the production area. The main purpose of setting up a fixed hot zone is to facilitate maintenance operations in workshops or units that often need to perform hot work. When carrying out hot work within this area, the procedures for applying for a hot work safety permit are waived.

(4) To carry out hot work in a Class I fire area, you must apply for a Class 1 fire certificate. This level of fire certificate shall be signed by the leader of the unit where the fire is located after a preliminary review and signature, and then submitted to the competent safety department for final approval.
When conducting hot work in a Class II fire area, a Class II fire permit must be applied for. This level of fire permit shall be subject to final approval by the supervisor of the unit where the fire is located.

(5) Before approving the fire certificate, the approving personnel at all levels should visit the hot work site in person, accurately understand the content, location, scope and other specific conditions of the hot work, and carefully check or supplement the safety technical measures for the hot work. , and confirm that the safety technical measures are reliable, and at the same time review whether the hot work permit is in compliance with relevant safety requirements. Only after confirmation is correct can the hot work of the project be signed and approved. Any accident caused by improper safety technical measures shall be held responsible by the person who approved the fire permit. If a hot work worker violates the safety regulations for hot work and fails to listen to dissuasion and causes an accident, the hot worker will be held responsible.

(6) The fire permit can only be used within the approved period and scope, and may not be used beyond the expiration date. The location of the fire work and the scope of the fire work may not be expanded at will. The validity period of each approved fire permit shall not exceed 7 days. If the fire permit expires but the work items are not completed, you must apply for a new fire permit.

(7) The fire permit should be issued within half an hour before the fire operation. There are two copies of the fire certificate. One copy shall be archived and kept by the safety officer of the fire work unit; one copy shall be carried by the fire work personnel for supervision and inspection by relevant personnel. Fire permits cannot be transferred or altered.

(8) For violations of regulations, failure to apply for a fire permit as required, incomplete approval procedures, failure to implement or complete safety technical measures, and lack of safe fire work conditions, fire workers have the right to refuse to perform hot work.

(9) Every employee of the company has the right to stop any illegal hot work and report it to the company’s safety technical department in a timely manner.

(10) When performing hot work, welders must assess the risk of fire in the work area and implement certain safety precautions if a threat is detected. The establishment of a fire watch is the most important precaution a welder can take against an accidental fire on a job site. Either the welder himself or an appointed laborer must become designated for a fire watch and stay in the area of the hot work for no less than 2 hours after the last of the hot work has been completed. This designated fire watch person must have a fire extinguisher and access to phone in case of a fire
