Professional fire extinguishing equipment during welding

A welder named Gu from a shipyard applied for a hot work permit from the on-site firefighter. However, the firefighter approved the permit before even arriving at the scene. After Gu used oxy-acetylene to cut a flammable wire, sparks flew from the oil slick on the ship's hull, igniting a massive fire. Those present tried to extinguish the fire with water and fire extinguishers but were unsuccessful, resulting in 5 deaths, 1 serious injury, and 3 minor injuries.

The main causes of the accident were:

(1) The firefighter was negligent and approved the permit without proper authorization, approving the hot work before even arriving at the scene.

(2) There was oil slick below the area where the hot work was to be performed.

(3) The personnel on site lacked fire extinguishing knowledge.

How can this accident be prevented?

(1) After receiving a hot work permit application, firefighters must thoroughly inspect the site and confirm safety before issuing the permit.

(2) They must ensure that there is no oil slick below the area where the hot work is to be performed.

(3) Employees must receive enhanced safety training.
