Ensure the below things during purchase:

Receiving,storing and usage of gas cylinders:

Ensure that they are properly labelled.

Do not accept cylinders without label of the content.

The color of the cylinders alone must not be depended upon.

Visually inspect for damage.

Ensure that the gas cylinders are received with valve caps.

Duties to be carried out during storing:

Gas cylinders must be stored in a separate storage area outside the building.

The storage area must be protected from weather.

Flammable gas cylinders must be separated from a distance of 6 m or by a wall of 30 minutes fire

Resistance.

Empty cylinders must be marked/tagged and stored separately.

Only gas cylinders for immediate use must be stored inside the premises.

Gas cylinders must not be stores near exits and passages.

Gas cylinders must be stored away from heat sources.

Close the valve with cap once the regulator is removed.

Cylinders must always be kept chained or supported in a manner to prevent fall.

Duties to be carried out during usage of cylinders:

Refer MSDS(Material safety data sheet) for the gases before usage,to know about hazards and precautions to be taken.

Do not tamper with the cylinder valves.

Always use the correct regulator for the cylinder.

Inspect the regulator for damage before use.

Never use damaged regulators,piping,etc

After the regulator is attached,the cylinder valve must be opened just enough to indicate pressure on the regulator gauge and all connections must be checked with a compatible solution for leaks.

Do not stand in front of the regulator gauge or the valve outlet side,while opening the valve.

Use safety glasses while working with gas cylinders.

Before a regulator is removed from a cylinder,the cylinder valve must be closed and the regulator relived of gas pressure.

Ensure proper ventilation in the area where gas cylinders are stored.

Spindle key must always be placed at an easily accessible location,for closing the valve in case of emergency.

A cylinder must never be emptied to a pressure lower than 25 psi as the residual contents may become contaminated if the valve is left open.

Close cylinder valve whenever work is finished or cylinder is empty.

Store toxic gases in gas cabinets.

Gas detectors must be installed for detecting gas leaks.

Cylinder valve and other fittings used with gas cylinders must be compatible with the type of gas used.

Incompatible materials can cause gas leak.

Greasy and oil materials must never be used on flammable cylinders or fittings as it can cause explosion.

In case of emergency:

If gas leak occurs from the cylinder inside the gas cabinet it must not be removed from the cabinet.

No attempt must be made to repair a leak from the base of the valve.

Personal protective equipment must be used while dealing with toxic gas leaks

The building must be evacuated immediately if a gas leak becomes uncontrollable.

Emergency measures must be undertaken only by trained personnel.

Gas supplier must be intimated immediately.
