【 Weak current College 】 fire and security essentials

In no-fire zone fire, should follow the following procedures and points:
(1) fire district fire ban shenzheng should go through the "application for permit" fire, auditing and approval, clear fire place, time, scope, fire scenarios, security measures, onsite guardian. No hot work permit or license not fire, fire certificates have expired are not allowed to fire; fire permit required security measures being implemented are not allowed to fire before; fire locations or content changes should repeat shenzheng procedures, it will be hot.
(2) contact fire before and related production workshop, the workshop section, clear fire equipment, location, specified by the production department the specialist is responsible for fire equipment replacement, sweeping lines, clean or clean-up work, and to make written records; by shenzheng fire safety management departments of informs neighbouring workshop, the section or Department, during the closed doors and Windows made fire, do not be unwinding, feed, not emptying the requirements of the job, and so on, to prevent the escape of flammable gases or combustible liquid leakage.
(3) units where it can be dismantled into fixed fire district or other safe place for hot job should not be on the production site (no-fire zone), in order to minimize the possibility of no-fire zone.
(4) isolation and repair of equipment such as fire to demolition, fire equipment and other production systems used with methods such as blocking blind plate for reliable isolation to prevent operation of equipment, pipe material leaks to fire equipment in the area of the fire; and other regions to take interim measures such as counterparties to screen, prevent Mars spatter caused fire incidents, paying particular attention to improving the the cable ditch near isolation measures.
(5) the removal of fuel will fire locations within all around l0m combustibles, such as solvents, lubricants, back to the thread, not cleaning the blooming of a flammable liquid, empty barrels, wooden, move to a safe location.
(6) implementation of the emergency fire-fighting measures, fire, fire stations nearby water sources to ensure sufficient, without interruption; in the hot spot ready for quantity sufficient fire; fire risk of important sections of the fire, fire engines and firefighters to the scene.
(7) the inspection and monitoring the work place, according to the provisions of the fire system, factory, workshop or fire safety department heads should be to the site to check the fire scenario presented safety measures to check whether you have implemented, and once again clearly and implement fire guardians and fire project leader, account security considerations.
(8) the fire of fire analysis too early, usually not earlier than the fire 30min. If fire breaks 30min above, should be to make fire analysis. Fire analysis of sampling must be representative, the analysis of the super hot sample you want to keep after the fire. Analysis of data should be recorded, the analyst should analysis laboratory reporting the undersigned. In theory, as long as fuel concentration is below the lower explosion limit, fire does not occur when on fire and explosion, but taking into account the representativeness of the sample, the analytical error, test the sensitivity of the analysis instruments, and so on, should have a certain security level. China's chemical industry enterprises require fire analysis qualified standards is: when a measuring instrument for testing, the explosion of the measured object's volume of a gas or vapour concentration should be ≤ 20 per cent lower explosion limit; if the use of other instruments, when measured gas or steam explosion limits ≥ 10% of its concentration should be less than 1 per cent; when the measured gas or steam explosion limits <4%,则其浓度<0.2为合格;若被测气体或蒸汽的爆炸下限> 4 per cent, its concentration < 0.5 per cent is qualified. If the tank fire, you should also comply with the tank job-related requirements.
(9) the fire operations officer fire operation and care shall be taken by the security officer of examinations, pressure vessel welding work should consist of the examination of the boiler and pressure vessel welder, no certificate shall not engage in welding work alone. Hot job when Mars spatter direction, use inflammable or nonflammable materials made of bezel control Mars spatter, prevent Mars fall fire risk areas. In the hot jobs in production equipment for the emergency evacuation or equipment, pipeline suddenly rupture, leakage of flammable substances, the guardian should immediately stop the fire, and instruction to return to normal, reparse qualified and channels of approval Department approval, to secure a new fire. High fire should comply with high job security provisions, five-level winds are not allowed to arrange outdoor fire, when carried out, the fire jobs should be stopped. For gas welding job, oxygen and acetylene cylinders shall not have the leakage, the drop location should place away from open flames, oxygen cylinder l0m above and acetylene spacing should not be less than 5m. For welders, welding machines should be stored at the specified location, FireWire and grounding should be intact, the prohibition of the use of an iron, etc instead of grounding and fixed earth point, electric welding machine grounded received in welding equipment, grounding should be close to the welding point, are not allowed to use long-distance ground loop.
(10) dealing with the aftermath of the fire should clean up after, turned off the fire, not missing any fires, cut off the fire power used by the job.
