Hardware factory ammonia leaks around 50 meters foul pungent

"Ammonia leaked! We hurried to run!" Xiao Zhang shouted while reporting to the police. After a few minutes, the workers escaped. Ammonia gas continues to diffuse in the air. The pungent, stench odor sneezes people and scares the workers who try to step forward and save themselves.

At 6:40 last night, ammonia gas leaked from Hongjin Road, Longchi Development Zone, Luzhou Taiwanese Investment Zone, a hardware factory. The Longchi fire squadron dispatched three fire engines and fifteen firefighters. It was plugged and diluted for one hour before the danger was ruled out.

The leaked ammonia tank, outside the workshop, has a capacity of about 3 cubic meters. Huang Longwen, the squadron leader of the Longchi fire squadron, said that when they arrived, they were 50 meters around and were filled with a pungent odor. "It smells like a lot of people are retching." In this case, firefighters quickly evacuated the onlookers.

Risks and dilutions take place simultaneously. Firemen used flowering water guns to spray water on leaking tanks. Four firefighters put on protective clothing and air respirator, carried plugging tools, and walked into the tank. Ten minutes later, they tightened the valve and no ammonia leaked.

It turned out that instead of the tank being broken, the valve was opened, causing large ammonia gas to emerge.

During the preliminary investigation, when a worker came forward to repair, he improperly operated the valve and opened the valve, causing ammonia leakage.

At about 7:40 that evening, firefighters continued to spray water, and the concentration of ammonia in the air fell to a safe level before they left.
