Acetylene Safety Tips
Acetylene is a highly flammable and explosive gas, so it is important to take proper safety precautions when working with it. Here are some acetylene safety tips:
- Wear appropriate personal protective equipment (PPE) when handling acetylene, including safety glasses, gloves, and flame-resistant clothing.
- Store acetylene cylinders in an upright position and secure them to prevent them from falling over. Keep them in a well-ventilated area away from heat sources and combustible materials.
- Keep a fire extinguisher nearby when working with acetylene, and know how to use it in case of an emergency.
- Do not smoke or use open flames in the vicinity of acetylene cylinders or when working with acetylene.
- Never attempt to fill or refill acetylene cylinders yourself. Leave that job to trained acetylene professionals.
- Ensure all system controls and safety equipment are working correctly before and during filling operations.
- Follow your daily and hourly checklists to ensure key steps are followed. Be sure to test compressor and generator trips (for abnormal pressure & temperature) on a regular basis.
- Before transferring carbide, confirm that an adequate nitrogen purge was completed.
- Perform periodic maintenance to verify all scales, safety reliefs and grounding/bonding systems are working to designed parameters.
- Immediately before devalving a cylinder for maintenance, always confirm that the cylinder’s contents have been vented to ambient pressure.
- Never use acetylene in an enclosed space or in areas where there is insufficient ventilation.
- Before using acetylene, make sure that all connections and hoses are secure and in good condition. Inspect them regularly for cracks, leaks, or other damage.
- Always use a flashback arrestor on the regulator and torch to prevent flames from traveling back into the gas supply.
- Never use acetylene at pressures higher than those recommended by the manufacturer.
- If you detect any unusual odors or suspect a leak, turn off the acetylene supply and ventilate the area immediately. Contact an acetylene technical expert to address the issue.
