Welding safety
Safety in gas welding
- Avoid the cylinder collision with sharp substance.
- A cap must be cover up when it is unused.
- Acetylene cylinder don’t kept lie on the ground.
- Cylinders always handle on the proper trolley with tight fastened.
- Do not make smoke at the place where cylinders have been stored.
- Do not hammering on the valve for opening.
- Cylinders should be exposed in flame, water or sunlight.
- Cylinders of oxygen and acetylene should be stored separate place.
- Cylinder valves always kept closed after work is finished.
- Always use proper pressure valve regulator.
- Cylinders should be stored in well ventilation room.
- Never attempt the mixes gas in a cylinder.
- For leak detection in valve socket and gland nut always with water and soap mixture.
- During moving the cylinder the valve must be closed.
- Do not interchanged the regulator valve.
- Torch nozzle always kept in clean and all time clean the its hole.
- Do not use spanner for removing or attaching the nozzle tip. The screw tips tight enough for gas tight joint.
- Never hang the torch with its hose on the valve regulator.
- Always protect the hose from circumferential damages.
- Fire extinguisher should be available.
- Before going to gas welding or gas cutting, the inflammable clothes should be removed from the body.
- Wear a appropriate apron.
- Use goggles with non-inflammable lenses and frames.
- Never do chipping or grinding without wear a mask or goggles.
- Do not carry the hot jobs.
- For igniting never use matches otherwise burned the hands.
General safety in arc welding
- The operator should wear anti-flame clothes to prevent burning and he should also protect himself from hot metals.
- The hand screen must be used for preventing the ultra-violet ray and infrared ray.
- Avoid the spatter fire hazardous from the welding area and there cover up with asbestos cloth if possible.
- Connection for welding should be made proper care and do direct ground if feasible.
- The connecting cable must be super insulated.
- The wok should not placed on combustible material.
- During chipping or slag removing the proper goggles should be wear.
- A fire extinguisher should always kept in hand.
- Helmets should be used.
- Proper ventilation must be provided in welding area.
- The black paint may be provided inside of the wall for killing the reflection rays.
