WELDING AND CUTTING
Welding and burning operations provide the potential for fires and injuries. The precautions listed below must be observed:
a. Before starting to weld or burn, inspect work area to assure that sparks or molten metal will not fall on flammable or combustible materials.
b. A suitable, approved fire extinguisher shall be ready for instant use in any location where welding is done. Screens, shields, or other safeguards should be provided for the protection of employees or materials, below or otherwise exposed to sparks, slag, falling objects, or the direct rays of the arc.
c. The welder shall wear approved eye and head protection. Employees assisting the welder shall also wear protective glasses.
d. Electrical welding equipment, including cable shall meet the requirements of the National Electrical Code. Welding practices shall comply with all applicable regulations.
e. When welding brass, bronze, galvanized iron or cadmium plated metals, adequate ventilation shall be provided to carry off vapors. A metal fume respirator should be used if the ventilation is not adequate.
f. For local exhaust suction devices to be effective, the exhaust hood entrance should be within nine (9") inches of the weld or cut.
g. Place all welding leads and gas hoses so they do not create a tripping hazard.

f. Ventilation - Precautions must be taken to see that fumes and dust are not breathed when cutting lead, lead alloys, painted iron or steel, lead-coated iron or steel, load-bearing steels of cadmium plated metals. Mechanical ventilation should be used to provide protection against breathing these materials. When this is not provided, a metal fume respirator or supplied-air respirator should be used.
g. Oxygen and acetylene cylinders shall be separated by 20 feet while in storage or be divided by a one hour fire rated divider at least 5 feet in height. "NO SMOKING" signs shall be posted and appropriate fire extinguishers shall be located 25 to 75 feet from the storage area.
