WELDING, CUTTING, AND BRAZING |

General Requirements - Fire Prevention and Protection |

Working in confined spaces involves additional safety precautions beyond the
basic and special precautions. A confined space is defined in 29 CFR 1910.252 as a relatively small or restricted space such as a tank, boiler, pressure vessel, or small compartment of a ship. Adequate ventilation is a prerequisite to work in confined spaces. When welding or cutting is being performed in any confined space, the gas cylinders and welding machines shall be left on the outside. When arc welding is to be suspended for any substantial period of time, such as during lunch or overnight, all electrodes shall be removed from the holders. The holders shall be carefully located so that accidental contact cannot occur and the machine shall be disconnected from the power source. |
