• Identify potential hazards associated with acetylene and oxygen cylinders
• Understand preventive measures for safe handling, storage, and usage
• Learn essential do’s and don’ts to reduce risks
• Prepare for emergency responses to potential accidents involving cylinders

• Fire/Explosion: Flammable gases like acetylene can ignite with minimal sparks if exposed to oxygen
• Asphyxiation: Leaking gas can displace oxygen in confined spaces, leading to suffocation
• Pressure Hazards: High-pressure gas can lead to burst hazards or accidents if cylinders are damaged or improperly handled
• Cylinder Tipping or Falling: A cylinder falling over can damage valves, leading to uncontrolled gas release

Storage:

• Store cylinders upright and securely fastened to prevent tipping
• Separate oxygen and acetylene cylinders by a minimum of 20 feet or use a fire-resistant barrier between them
• Keep cylinders in well-ventilated areas away from direct sunlight, heat sources, or open flames

Handling:

• Inspect cylinders for damage or leaks before use
• Use cylinder carts or dollies with chains or straps for safe transport
• Keep valves closed when cylinders are not in use

Usage:

• Use a regulator designed for each specific gas cylinder
• Open valves slowly to prevent rapid gas release
• Use flashback arrestors to prevent flames from traveling back into the cylinder

Do's

• Use proper PPE (Personal Protective Equipment), including gloves, safety goggles, and aprons
• Test for leaks regularly with a soapy water solution (do not use open flames)
• Label cylinders clearly for easy identification
• Report any damaged or defective cylinders to supervisors immediately
• Use non-sparking tools when handling cylinders

Don’ts

• Don’t store cylinders near electrical circuits, heat sources, or in confined areas
• Don’t tamper with safety devices or regulators on cylinders
• Don’t lift cylinders by the valve cap or handle them roughly
• Don’t use acetylene at pressures exceeding 15 psi
• Don’t allow oil, grease, or other flammable substances to come into contact with oxygen cylinders or fittings

• Safety goggles or face shields to protect from sparks and flashes
• Leather gloves to protect hands from cuts or burns
• Flame-resistant clothing to reduce burn risk
• Steel-toe boots to protect feet from dropping cylinders
• Hearing protection if working in noisy areas or near equipment

Leak Detection:

• Evacuate the area immediately if a significant leak is detected
• Use ventilation to clear the area of gas if possible

Fire:

• If a fire occurs, shut off the gas supply if it can be done safely
• Use appropriate fire extinguishers (e.g. Class ABC)

Explosion:

• Alert nearby personnel and evacuate
• Follow emergency response plans for severe incidents

First Aid

• Provide fresh air and administer oxygen if a worker is affected by fumes or gas
• Seek medical attention immediately in case of burns or inhalation injury
