Risk overview

Acute:Asphyxia caused by inhalation. If the oxygen content necessary for life in the air is reduced, exposure to anoxic(<19.5%)can cause dizziness, nausea, vomiting, loss of consciousness and death. Eye and skin contact have no adverse effects.

 

Chronic: insufficient oxygen supply will affect the heart and the nervous system

 

Environmental hazard: None

 

Danger of explosionWhen exposed to high heat or flame, the pressure in the cylinder will rise, and most of the cylinders are designed to release the high pressure gas from the rupture disk of the bottle valve. If the rupture disk fails, it can cause the explosion.

 

 

 

TRANSPORT INFORMATION

UN/ID No. : UN1046

Proper shipping name : HELIUM, COMPRESSED

Class or Division : 2

Tunnel Code : (E)

Label(s) : 2.2

ADR/RID Hazard ID no. : 20

Fire control measures

Hazard characteristics: pressure in cylinders increases when exposed to high heat or flame. Most cylinders are designed to release high pressure from the cylinder valve rupture

Gas, if the rupture fails, can cause an explosion.Harmful combustion products: none

Fire extinguishing method: suitable for fire extinguishing source

Fire extinguishing agent: non - combustible and non - combustible, use suitable fire extinguishing agent

Fire precautions: if feasible, move cylinders out of the fire zone or use water mist to cool them. Emergency personnel need SCBA

Emergency treatment of leakage

Emergency treatment: isolate all personnel from the leakage area, conduct ventilation and ventilation in the area and monitor oxygen content, and use SCBA

Elimination method: allow emission to the atmosphere

 

 

Handling and storage

Operation precautions:

Never pull, roll, or slide cylinders.Use a suitable handcart to move the cylinder. Do not try to hold the lid of the cylinder to lift it.Ensure that the cylinder is in a fixed state during the whole process of use.Release gas safely from the cylinder using a pressure relief regulator or separate control valve.Use a check valve to prevent backflow.Do not heat cylinders to increase pressure and discharge.Open the cylinder valve slowly and carefully when the cylinder is connected to the process.If the user has difficulty operating cylinder valves, stop using them and contact the supplier.Do not insert tools (e.g. wrench, screwdriver, skid bar, etc.) into the bonnet.Otherwise, the valve may be damaged and leak may occur. Use an adjustable ring chain wrench to open the overtight cap.Use labels for solid, in-service, and defective cylinders to determine cylinder condition.To prevent air from entering the cylinder, do not exhaust the gas completely. After use, lock the valve outlet cover (PLUG) with a torque wrench.Special attention should be paid to the use of such gases in confined Spaces.

Storage precautions:

The storage temperature shall not exceed 42℃. There shall be no combustible materials in the storage area and it shall be far away from frequent access and emergency exits.No salt or other corrosive material shall be present.For unused cylinders, the protective bonnet and output valve should be kept intact.Store empty and full bottles separately.Avoid excessive storage and storage time.Use fifo system to maintain good storage record.
