1.2.6 Safety precautions for skin burns
Observe the safety precautions to prevent skin burns. Ignoring heat, spatter, and sparks
during operation could cause a fire or burned skin.
1. Do not perform cutting near flammables. (Move flammables well away from the sparks.)
2. Do not cut containers filled with flammables.
3. Do not keep lighters, matches, and other flammables nearby.
4. Flames from the torch will burn the skin. Keep your body away from the torch and tip, and
check the safety before operating the switches and valves.
5. Wear the correct protectors to protect your eyes and body.
6. Correctly tighten the tip to prevent backfire.
● When fixing a tip to the torch, tighten the nut with the two wrenches attached.
● If the tip is tighten excessively, it will be heated during cutting and tightened still more,
making it difficult to remove the tip.
● Avoid damaging the taper of the tip since this may cause backfire.
7. Check with soapsuds for any leakage of gas from the connection part of the distributor,
hoses and torch. Never use oil or grease on the connection of the oxygen pipe to avoid
backfire which may lead to explosion.
8. Be sure to check the following when igniting:
● Place the torch on the torch holder before igniting.
● Wear the required protectors (gauntlets, helmet, goggles, etc.)
● Check for any obstacles, dangerous materials and flammables near or in the direction of
cutting.
● The surface temperature is very high, so do not touch it even you wear gauntlets.
