How to handle leaks or fires in trisilicon or tetrasilicon storage tanks or pipelines?

First, shut off the material valve associated with the leaking equipment, then try to empty the material inside it, followed by purging that material from the equipment until fire testing and analysis show satisfactory results; finally, carry out repairs.

Leak of trichlorosilane: In the event of a trichlorosilane leak, personnel in the affected area must be quickly evacuated to a safe zone, and the area should be isolated to strictly control access to it. Cut off and eliminate all possible sources of fire. Emergency responders wear self-contained positive-pressure breathing apparatus and fire protection suits, entering the scene from the upwind side. Seal the source of leakage as much as possible to prevent it from entering confined spaces such as sewers. Minor leaks: Absorb or collect them using sand or other non-flammable materials. Large-scale leakage: Build dikes or dig pits to contain it ； Use dry powder, dry sand ； Cover. Remove under the guidance of an expert. Silicon tetrachloride leakage: In the event of a leak of silicon tetrachloride, personnel in the affected area must be quickly evacuated to a safe zone, and the area should be isolated to strictly control access. Emergency responders wear self-contained positive-pressure breathing apparatus and acid-alkali resistant protective clothing, entering the scene from the upwind side. Seal the source of leakage as much as possible. Prevent entry into confined spaces such as sewers and drainage ditches. Minor leakage: Sprinkle soda ash on the ground, then rinse thoroughly; the diluted wash water can be discharged into the wastewater system. Large-scale leakage: Build dikes or dig pits to contain it ； Remove under the guidance of an expert.

First, shut off the material valve associated with the leaking equipment, then fill it with nitrogen for protection and displacement.

The trisilicon carburetor contains liquid material; what if there is a leak and fire breaks out at its bottom flange? Use nitrogen to press material into the spare tank; introducing nitrogen increases pressure, which leads to more leaks and a stronger fire. So what should be the flow rate of nitrogen?

Reply to 5# zjr1111: Brother, make good use of the nitrogen on site – use it to blow at the location where the fire is occurring, and extinguish it with fire-resistant cloth. Nitrogen is an excellent fire extinguishing agent; it’s better than dry powder fire extinguishers.

Anyway. Nitrogen is a miracle substance.
