【 Weak current College 】 fire extinguishers configuration and management of issues and recommendations---Power By 【 China power house network 】

Fire extinguisher is effective suppression of commonly used tools in the early days of fire. Because of its small size, configuration and management is relatively simple, easy to operate, which has been widely used. However, from some of the power of the firms in the fire safety inspection found that fire extinguishers configuration and management, there are several common problems need to be addressed.

1 fire extinguishers configuration is in place

New power projects into production before the trial operation, automatic fire-fighting configuration well-functioning, but fire extinguishers configuration is in place. Mainly due to:
(1) the overall fire design, attention to the design of the automatic fire fighting system, the design of the fire extinguishers were ignored, resulting in the design of fire extinguishers, omission did not raise a reasonable configuration basis;
(2) Notwithstanding the configuration design, but because configuration permissions not belonging, of fire extinguishers configuration in place could not be justified;
(3) Although configured according to the design, configuration, quality, selection, insufficient number, location, and some even used fire extinguishers.
The author recommends new power engineering fire extinguishers configuration can be controlled in three steps:
(1) design units should be strictly in accordance with the relevant fire design specifications fully fire design, the design of fire extinguishers configuration included in the fire protection design content, on the one hand, ensure the integrity of the design, on the other hand will configure funds included in the plan, are not in place not because of money from affecting fire extinguishers configuration;
(2) explicitly configure the unit in charge, it is best to construction unit should be disposable or press project progress step-by-step configuration of fire extinguishers;
(3) in the configuration of the responsible party and take over the establishment of restriction mechanism between the parties, will produce acceptable units as of fire extinguishers configuration, commissioning and acceptance test operation in the former press fire designs and requirements for acceptance.
2 fire extinguishers configuration not reasonable
Fire extinguishers configuration is a rule-based, the construction of fire extinguishers configuration design code (GBJ140-90) on the design of fire extinguishers configuration places risk level, fire suppression levels, type selection, configuration baselines and configuration requirements, have made a clear and detailed; the electricity equipments of the Statute of the typical fire as the internal regulations of the electric power industry, electric power production enterprises, and in particular supply enterprise design of the substation fire extinguishers configuration provides more specific, as fire extinguishers configuration design and management should be learning to master, as fire extinguishers configuration and management of unified standards to guide fire extinguishers configuration and management. However, in the daily fire extinguishers configuration and management are 3 unreasonable phenomenon should pay great attention.
(1) fire protection. Fire extinguishers configuration, management and use of inappropriate, not only affect the extinguishing effect is also extremely vulnerable to injury accident caused explosion. For example, in the electric power construction site or electrical equipment, fire extinguishers, long-term placement in the wind, the Sun, the rain environment, extremely easy to keep a fire extinguisher tube body corrosion and aging, carrying capacity is reduced, or extinguishing agent lumped, reduce the effects of fire extinguishing agent quality, safe and effective use of. To this end, the authors recommended that fire extinguishers configuration should take boxing, hooks, shelves, supports, such as rain-Pont sunscreen moisture-proof, fire extinguisher set point temperature should be located away from power production.
(2) a single configuration point fire extinguishers. In accordance with the construction of fire extinguishers configuration design code, fire extinguisher, the correct settings for each configuration should not be less than 2, maximum should not be greater than 5, and should be different fire extinguisher protection distance settings configuration. But some power Enterprise fire extinguishers configuration is too centralized, in a configuration point number of fire extinguishers configuration is far higher than 5 are mistaken for configuration standards, the more able to meet the needs of extinguishing fire.
(3) fire extinguishers improper selection. Power companies of fire type generally have electrical equipment fires, precision instruments, fire, fuel gas fire, oils and generally solid fire, at present, the commonly used fire extinguishers in accordance with the extinguishing agent can be divided into the following five types: water, foam, dry powder, halon-, carbon dioxide. Due to the different principles of fire extinguishing agent, the application object and use the results would be very different. For example, ABC class and BC powder extinguishing agent, ABC class can be used for solid, liquid, gas fire three-State material, while the BC class can only be used for liquid and gaseous substances fire. Some electricity enterprises of fire extinguishers configuration does not distinguish between types of fire, do not configure the "disease", is a valid have put out the fire. Common power enterprises in different fire extinguishers selection of correct as shown in table 1.

3 does not properly implement the provisions of the fire extinguisher scrap

In order to ensure that the fire extinguisher use safety and effectiveness, proper maintenance of fire extinguishers and the scrap is necessary, to this end the Ministry of public security in 1995 developed the fire extinguisher maintenance and scrap "public security industry standards, as a mandatory industry standards, including on fire extinguisher inspection, maintenance and end-of-methods and deadlines are clearly defined. In the case of hand-held 1211 fire extinguishers: expire 5 years (from the date of manufacture), after every 2 years must be used to check the water pressure test; 10 years (from the factory date) must be discarded. However, some fire management personnel as to the standard master, a hydraulic pressure test is considered to be annual inspection, regardless of age to do every year; the second is the only annual check, but not implemented by the service life, causing a fire extinguisher scrap extra-service, fire extinguisher quality cannot be effectively guaranteed.

4 fire management have a blind spot

Fire management content many blind spots, there are:
(1)-set management, due to factors such as the use of fire extinguishers work cannot be promptly returned, not only in inconvenience to management, also affect the normal scope of protection and use;
(2) not to establish fire equipment, fire-fighting equipment base archives, to repair, scrap inconvenience;
(3) training in the use of fire extinguishers in the penetration rate is not high, but that is not configured to use the fire extinguishers are useless.
The author recommends a fire extinguisher practice archives-set management, archive accurate rendering configuration chart, record the number of fire extinguishers, configuration and maintenance check time to reset the licensing form clear responsibilities in administrators to indicate the configuration pointWith the use of fire extinguishers, and calls for non-fire control.
Fire extinguishers for reasonable configuration and management involves the initial fire suppression work of success or failure, power companies to implement fire safety, it must attach great importance to fire extinguishers configuration and management.
