Chemicals Commonly Associated with Welding, Cutting, and Brazing
|
The following list identifies chemicals commonly associated with these operations. Each chemical name links to the corresponding entry in the OSHA Chemical Sampling Guide. For more specific information on sampling and analysis see the Samping and Analysis Safety and Health Topics Page or refer to the appropriate OSHA Sampling
and Analytical Method. In this listing the term welding is meant to include cutting and brazing.
- Metals. The metals that may be present will depend on the material being worked on, and the makeup of welding rods, fluxes, etc. For this information see the appropriate Material Safety Data Sheets.
