The Basics of Welding Safety (Part 1)

The new Hexavalent Chromium standard, as well as other welding related respiratory issues have been at the forefront of safety related issues long enough for most of us to be aware of some of the hazards associated with welding.

Respiratory protection issues, though certainly important, are by no means the only hazards to be aware of when looking at welding. Today and in the next couple of days we are going to be looking at the hazards associated with welding and how to make sure that welding is safe.

The hazards associated with welding include:

• Noise
• Fumes/Respiratory
• Heat/Burns
• Ultraviolet Radiation
• Electrical Safety Issues

Noise

While Noise probably isn't the first safety hazard most people associate with welding, there are good reasons to consider the issue. Arc welding equipment, as well as the generators and the actual noise generated by the welding process all combine to produce noise levels above the 85 dB threshold. Extended exposure to this high level of noise can and does, result in partial or complete hearing loss over time.

If in doubt, purchase a simple 3M Noise Indicator. It flashes green when noise levels are below 85 dB and red when the noise levels exceed it. Other options include sound level meters and noise dosimeters. You can also opt to have an Industrial Hygienist come in and monitor noise levels for you.

An additional consideration regarding ear plugs or ear muffs is the added protection that they afford for the ear canal. Flying sparks and metal pieces can easily bounce into the ear canal causing substantial pain and injury. Whatever form of hearing protection you use, you are also plugging the ear canal and keeping hot sparks and metal pieces out.
