At the hazardous chemical leakage drill site, the emergency command center learned that when
two hydrogen transport vehicles were loading and unloading, a large number of valves leaked
from the hydrogen vehicles and one person was injured. The command center immediately
notified fire rescue, emergency rescue, and medical rescue to launch rescue and rescue operations.
UAVs and fire extinguishing robots rushed to the leak first, used remote visualization methods
to patrol and perceive the accident site dynamics at low altitudes, and at the same time
transmit real-time data back to the site command. Soon, the fire rescue vehicle arrived.
Aiming at the actual situation of the injured people being exposed to the air of hazardous
chemicals, the water mist fire extinguishing system and high-pressure water gun were used
to spray the valves to contain the danger by absorbing heat, reducing the oxygen concentration,
and blocking pollution,cooling and extinguishing. Then, 120 ambulances rushed to the scene
to treat the wounded. After monitoring the area related to the accident twice, and at the same
time recycling and disposing of pollutants by using chemical absorbent pads,chemical absorbent booms
and chemical absorbent socks, the air quality reached the standard and the leaked hazardous
chemicals were basically disposed.
