Analysis of potential safety hazards of dry powder fire extinguisher damage and failure
1. Hidden danger photos
2. Description of hidden dangers
This is a fire extinguisher loss of pressure at a construction site and has not been replaced in time.
3. Basis for Judgment
(1) Article 5.21 of the Code for Acceptance and Inspection of Building Fire Extinguishers GB50444-2008: It is stipulated that ordinary building sites shall conduct a comprehensive inspection of fire extinguishers at least once a month, including configuration inspection and appearance inspection.
(2) Article 5.31 of the Code for Acceptance and Inspection of Building Fire Extinguishers GB50444-2008: It stipulates the specific conditions for fire extinguishers to be repaired, including fire extinguishers found to have mechanical damage, obvious rust, fire extinguishing agent leakage, fire extinguishing agents that have been opened and used or fire extinguishers that meet other maintenance conditions, all need to be sent to fire extinguisher manufacturers or fire extinguisher professional maintenance units for timely maintenance.
4. Hidden danger analysis
The fire extinguisher on the construction site should be seen everywhere, and it should be effective and usable, especially in winter construction, where the weather is cold and the pressure of the fire extinguisher is insufficient. On the one hand, the root cause is that the poor conditions lead to thermal expansion and contraction, so that the pressure of the fire extinguisher is insufficient. On the other hand, inspectors are not inspected and replaced in a timely manner.
5. Corrective measures
(1) Inspect and replace the fire extinguisher in a timely manner, formulate a monthly inspection record form, check and fill in the record form regularly, and replace and repair the fire extinguisher in a timely manner if it is found to be damaged, lost pressure, expired and other phenomena.
6. Management Recommendations
(1) Pay attention to safety inspections at ordinary times, formulate monthly inspection record sheets, and eliminate hidden dangers in a timely manner after multiple inspections in one month.
(2) Carry out learning, education and training for operators to understand the use, failure, storage location and other common sense of fire extinguishers. Improve the safety awareness of managers and operators, especially after discovering potential safety hazards, find out the causes, rectify them in time, and then conduct training and warning education on such hidden dangers.
(3) Implement the safety condition verification system, implement the confirmation measures of the working environment, take the measure as a process or link, investigate the hidden dangers of the working environment before the operation, and start the operation only after the safety conditions are met.
7. Accident cases
Fire fighting has always been the top priority of the national enterprise inspection, for the discovery of hidden dangers to raise problems, the state has also carried out corresponding punishments, the purpose is to eliminate these potential safety hazards in the cradle, not to cause personnel and economic losses to the enterprise society.
