material whose contents, when heated, can produce flammable or explosive va- pors. Clean and purge containers before applying heat. Vent closed containers, including castings, before preheating, welding, or cutting.

11.Avoid overexposure to fumes and gases. Always keep your head out of the fumes. Do not breathe the fumes. Use enough ventilation or exhaust, or both, to keep fumes and gases from your breathing zone and general area.

•Where ventilation is questionable, have a qualified technician take an air sam- pling to determine the need for corrective measures. Use mechanical ventilation to improve air quality. If engineering controls are not feasible, use an approved respirator.

•Work in a confined area only if it is well ventilated, or while wearing an air-sup- plied respirator.

•Follow OSHA guidelines for Permissible Exposure Limits (PEL’s) for various fumes and gases.

•Follow the American Conference of Governmental Industrial Hygienists recom- mendations for Threshold Limit Values (TLV’s) for fumes and gases.

•Have a recognized specialist in Industrial Hygiene or Environmental Services check the operation and air quality and make recommendations for the specific welding or cutting situation.

Inhalation Hazard

Welding Produces toxic fumes and gasses.

Exposure to welding gasses can increase the risk of developing certain cancers, such as cancer of the larynx and lung cancer.

Also, some diseases that may be linked to exposure to welding gas- ses or fumes are:

• Early onset of Parkinson’s Disease

• Heart Disease

• Damage to the reproductive organs

• Ulcers

• Inflammation of the small intestine or stomach

• Kidney damage

•Respiratory diseases such as emphysema, bronchitis or pneumonia

Safety precautions, such as using natural or forced air ventilation and wearing a NIOSH-approved respirator, are essential to reduce the risk of developing the above illnesses.

12.Read and understand all instructions and safety precautions as outlined in the manufacturer’s manual for the material you will weld or cut.

13.Do not touch live electrical parts. Wear dry, insulating gloves. Do not touch elec- trode or conductor tong with bare hand. Do not wear wet or damaged gloves.
