Personal Protective Equipment
Published in John F. Rekus, Complete Confined Spaces Handbook, 2018
Welding helmets are a special type of face shield that protects the eyes and face from flying particles and UV radiation created by welding processes. Since electrode size influences the intensity of the arc, welding helmets are designed to accept filters of varying optical densities.
Personal Protective Equipment (PPE)

Welding requires the protection of the entire face from both hot particles as well as radiation hazards (see Figure 11.8). Welding torches and arc welders can emit both heat (infrared) and strong ultraviolet radiation (especially electric arc welding). The degree of protection needed from the shaded glass lens in the welding helmet is determined by the type of welding being performed. It should also be noted that welding may also require respiratory protection and hearing protection, depending on the nature of the work being performed.

Personal welder air samples were collected in the worker’s breathing zone by clipping the cartridge high on the shirt lapel such that it was positioned between the collarbone and chin and behind the welding helmet when it was lowered. Personal metalworker air samples were collected in the worker’s breathing zone by clipping the cartridge to the shirt lapel. Bystander area samples were collected at a height of approximately 1.5 m (5’). One field blank was provided for every 10 air samples collected. Sampling filters were analyzed by an American Industrial Hygiene Association accredited analytical laboratory (SGS Galson, East Syracuse, NY). The samples were analyzed using inductively coupled argon plasma atomic emission spectroscopy (ICP-AES) per NIOSH Method 7303.[31]

Four to seven personal samples were collected during each hot work process in the workers´ breathing zone mounted below the respirator or the welding helmet, if these were used. The length of sampling time varied between 15 and 75 min depending on the duration of the work operation.
