1.2.2 Pressure regulator safety precautions
1. Before starting operation, check that all pressure regulators are operating correctly.
2. Ask a skilled repair engineer to perform maintenance and inspection service.
3. Do not use pressure regulators from which gas is leaking, nor malfunctioning
pressure regulators.
4. Do not use pressure regulators smeared with oil or grease.
1.2.3 High-pressure gas cylinder safety precautions
1. Never use broken cylinders or cylinders from which gas are
leaking.
2. Install cylinders upright and take measures to prevent them from falling.
3. Use only for specified purposes.
4. Do not use the cylinders which smeared with oil or grease.
5. Install cylinders in a place free from heat, sparks, slag, and open flame.
6. Contact the distributor if the container valves will not open.
7. Never use a hammer, wrench, or other tools to forcibly open container valves.
1.2.4 Safety precautions for hoses
1.Use the oxygen hose for transferring oxygen gas only.
2.Replace cracked hoses or other hoses damaged by sparks, heat, unshielded fire, etc.
3.Install hoses without twisting.
4.To prevent breakage of hoses, take great care during operation and transportation.
5.Do not hold the hoses when moving the machine.
6.Periodically check the hoses for damage, leakage, fatigue, loose joints, etc, to
ensure safety.
7. Cut hoses to the minimum possible length. Short hoses reduce hose damage and
pressure drop, as well as reduce the flow resistance
1.2.5
Safety precautions for fire
Take safety precautions to prevent fire prior to gas cutting. Ignoring hot metal,
sparks, and slag could cause a fire.
1. Keep a fire extinguisher, fire extinguish sand, bucket full of water, etc. ready on
the site where gas cutting is performed.
2. Keep flammables away from the cutting area to avoid exposure to sparks.
3. Always cool down steel plates that have become hot after cutting, as well as
hot cut parts or scrap, before bringing them close to flammables.
4. Never cut containers to which flammable materials are stuck.
1.2.6 Safety precautions for skin burns
