lead Welding - Galvanized, Indoors Purpose Engineering and Administrative Controls The following procedure is used when performing welding activities indoors on galvanized metals. Galvanized coatings contain lead. If the following engineering or administrative controls are used. respirators and protective clothing are not required: Local exhaust ventilation (LEV), sk Removal of galvanize material coating (at least 4 inches from either side of the weld area) by grinding, sanding, or power tool cleaning. (See Section 4.4) Safety Equipment Safety equipment required for welding galvanized metal shall include, but Requirements not be limited to, the following: Minimum safety equipment required in area Supplied air respirator (29 CFR 1910.252) mandatory if LEV is not used Welders gloves, spats, jacket, leggings, long sleeve cotton or flame resistant shirts Welding hood Protective clothing: disposable clothing(i.e. Tyvek or Pyrolon) or furnished clothing which will not leave work site Shoes or disposable boot covers Additional Requirements Use the following when welding on galvanized metals indoors: If welding indoorsfor > 2 hours by any employee in any 8-hour shift, ihefollowing will also be required unless engineering or administrative controls are used.
