Gas Cylinder Handling, Storage and Use

Responsible supervisor/s: Michael Joseph

List the Hazards and risk controls as per risk assessment

Associated risk assessment reference:

Hazards

Cylinders are heavy – (use heavy Item Risk assessments)

Asphyxiation by gas leaks

Chemical incompatibility

Damage to eyes form rapidly escaping gas

Risk controls

Wear safety shoes, use cylinder trolley or 3-wheel trolley and the attached safety straps and use appropriate safe lifting techniques/postures when handling cylinders. Ask others for help if necessary.

Calculate the risk level associated with keeping gas in a room before moving gas in, store and transport cylinders correctly and conduct regular leak tests.

Do not store or transport together different dangerous goods classes.

Ensure eye protection is worn.

List resources required including personal protective clothing, chemicals and equipment needed

Safety shoes and protective eye wear should be worn when handling cylinders

Cylinder trolley or 3-wheel trolley with safety strap

Lab coat if working in a laboratory area

List step by step instructions or order for undertaking the task

Transporting Cylinders

Safety shoes and protective eyewear should be worn when handling

Use cylinder trolley or 3-wheel trolley and the attached safety straps

Observe appropriate safe lifting techniques/postures

( http://sydney.edu.au/whs/guidelines/manual_handling/index.shtml

) prior to manually handling heavy or large gas cylinders

Valves must be closed when moving & equipment (e.g. regulators) removed

Do not knock cylinders violently or allow them to fall, never roll along the ground in horizontal position as valve may open

SAFE WORK PROCEDURE

 Do not ride in a lift with cylinders. Send the cylinder on its own with a sign attached to it stating “DANGER- do not travel in lift - Compressed Gas Cylinders being transported”.

Using Cylinders within Labs

Before moving a cylinder into the lab you must contact either the Resources Officer or Safety Officer with the following details: o Cylinder size and gas type o Building and room number o Cylinder size and gas type of other gases also contained in the room

Store upright and secure with a cylinder wall bracket

Store & use in cool, well-ventilated area, away from heat sources, ignition sources & combustible materials

Regularly check for leaks and faults following the guidelines on page 367 of the BOC Gas Cylinder Safety

Manual and the table below.

Never use force to open or close valves or attach regulators or fittings

Keep oil & grease away from cylinders, valves and fittings

Before assembling regulators and fittings make sure there are no particles of dirt in the cylinder valve outlet. If a supply of clean compressed oil free air or nitrogen is available, then, whilst wearing appropriate eye and ear protection, use this to blow out any loose particles of dirt from the valve outlet. If a supply of clean compressed oil free air or nitrogen is unavailable, then use a clean lint free rag to clean the cylinder valve outlet, in particular the sealing surfaces. Never open a cylinder valve to clear the outlet. For flammable gases this often leads to the ignition of the escaping gas. Ejected particles and resultant noise can also injure adjacent personnel.

Only use regulators designed for a particular gas type. Not all regulators can be used with all gasses.

Storing Cylinders in Cages When Not in Use

Keep full & empty cylinders separate

Toxic and corrosive gases should be stored separately, away from all other gases

Do not knock Cylinders violently or allow them to fall.

List emergency shutdown procedures

N/A

List Emergency procedures for how to deal with fires, spills or exposure to hazardous substances

Shut off the gas if it is safe to do so

If there is no fire, open windows and doors to allow gas to escape

Evacuate the area if the leak is dangerous

If the leak could endanger others in the building (e.g. significant toxic gas leak) or there is potential for a fire or explosion, evacuate the immediate area, activate a break-glass emergency alarm, phone security

(9351 3333) and send someone to report to the buildings Chief Warden

All incidents are to be reported to your immediate supervisor

Incidents resulting in injury or illness and any near-miss incidents must be reported in RiskWare https://riskware.sydney.edu.au
