Decision Guide for Welding Respirators

Moldex
Welding Respirator Flowchart

Note: R and P filters can be used in environments with or without oils present.

Warning: This guide may be used as an aid to select appropriate respiratory protection for specific contaminants. Because conditions at the worksite can vary substantially, a comprehensive evaluation must be made to determine the correct respiratory protection. When contaminants at a worksite have been identified and concentrations measured, this guide may be used to select the appropriate respirator. Only qualified professionals, familiar with the actual working conditions and knowledgeable in the benefits and the limitations of respiratory protection equipment, should make the selection. Before making the selection, users must also read and understand the applicable MSDS, specifically the section on respiratory protection, for the welding products they plan to use. Users must also refer to the Moldex Chemical Selection Guide before making the final selection. If the selection criteria changes, including, but not limited to, worksite conditions, consumers, or standards and regulations, a new evaluation must be made to determine the appropriate respiratory protections.

Proper use of Moldex products must be determined by the employer and must be in accordance with all applicable local, state, and federal regulations including OSHA 29CFR1910.134.

Warning: This chart may be used as an aid to select the appropriate respiratory protection for a specific contaminant. This chart is not all inclusive and varies depending on the consumables used. Please refer to the consumable manufacturer’s MSDS, before selecting a respirator. Only a qualified professional, familiar with the actual working conditions and knowledgeable in the benefits and limitations of respiratory protection equipment, should make the selection. Please refer to latest version of the Moldex Chemical Selection Guide for help in choosing the appropriate respirator. Protection from ozone is for concentrations less than the OSHA PEL. Please refer to the warnings above for more information.

WARNING - DO NOT USE MOLDEX RESPIRATORS IF ANY OF THE FOLLOWING APPLY:
  • Your welding environment is immediately dangerous to life and health
  • Your welding environment is a confined space
  • Your welding environment has contaminant levels greater than 10x PEL
  • You use chlorinated hydrocarbons when are welding (e.g. degreasers)
  • There are other unknown contaminants present
  • Your welding environment contains less than 19.5% oxygen
