Part IV: General Rules
Welding and Soldering
OSHA citation 1910.251-257
- Welding requires that goggles, shields, proper clothing and approved gloves be worn while performing the operation.
- When using torches for cutting or soldering, be sure there is a fire extinguisher on hand and ready for use if the need arises. Work away from combustible materials if possible. Check the area after stopping for the day to make sure no smoldering materials remain.
- Shut off torches at the tank at noon, at night and any other extended time when not in use.
- Shield the welding area in such a manner as to prevent the arc of flame from being seen by bystanders.
- Take great care to assure acetylene and oxygen tanks are securely fastened to prevent their falling over or being knocked down, both on the job and during transportation.
- It is required by OSHA that all gases be stored separately in well-ventilated areas whenever possible, in a room with fire-resistant walls.
- Use all possible ventilation when welding or soldering. Wear respirators of proper design when welding toxic material (e.g., galvanized iron) to avoid breathing harmful fumes. Where ventilation is poor, metal fume respirators can sometimes be used. Local exhaust ventilation is required when welding on or with certain substances.
- Silver solder containing cadmium must be used with the greatest care. Always use sufficient local exhaust ventilation.
- Do not weld in the same work area where flammables or combustibles are present.
- Lead solder shall not be used under any circumstance.
- Hot work permits may be required for this type of work. Contact your supervisor for more details.
