What are the safety specifications for nitrogen pipeline engineering

Nitrogen has no obvious toxic effect, due to tasteless, colorless and odorless, so it can’t be detected when the content in the air is high, and it is life-threatening if the oxygen content is lower than 18%. Liquid nitrogen can cause frostbite to eyes, skin and respiratory tract, so what are the safety techniques of nitrogen pipeline? The following Gaitherspark gas pipeline engineering manufacturers will be introduced to you.

Fire-fighting measures Hazardous characteristics: Nitrogen itself is not combustible, but nitrogen containers and equipment may explode when exposed to open flames and high temperatures, resulting in a sharp rise in pressure inside the container. Water should be used to cool the container in the fire. Hazardous combustion products: No fire extinguishing methods and extinguishing agents: Use water to cool containers in the fire scene and use extinguishing agents suitable for the fire environment to extinguish the fire.

Emergency Response to Leakage Emergency Response: Cut off the gas source and quickly evacuate the leakage contaminated area. When dealing with the leakage, the handler should wear self-contained positive pressure respirator, and the handler of liquid nitrogen should wear anti-freezing protective gear.

Operation, Disposal and Storage Precautions for Operation and Disposal: Make ventilation equipment. When handling liquid nitrogen, frostbite should be prevented. Precautions for storage: Store in a ventilated warehouse, away from fire and heat source, and the gas cylinder should be protected against dumping. Cryogenic liquid storage tanks larger than 10 cubic meters should not be placed indoors.

Exposure control/individual protection Maximum permissible concentration: no information Monitoring method: chemical analysis or instrumental analysis, engineering control production process closed, strengthen the ventilation of the environment. Respiratory protection: When the concentration in the air exceeds the standard, the site should be evacuated quickly; wear air respirator or oxygen respirator when rescuing or dealing with accidents Eyes protection: Wear a face mask when contacting liquid nitrogen. Body protection: Wear cold-proof clothing in low-temperature working area. Hand protection: Wear cotton gloves in low temperature environment.

Toxicological information Acute poisoning: Nitrogen itself is non-toxic, oxygen content below 18% is life-threatening, hypoxia symptoms of nausea, drowsiness, eyelids and skin turn blue, unconscious until death by asphyxiation.
