Patricia,

There are distinct differences among the various cartridges according to what NIOSH approves them for use in the workplace.

Organic Vapor Cartridges are NIOSH approved only for Organic Vapors. The cartridges is color coded black.

Acid Gas Cartridges are NIOSH approved for Chlorine, Hydrogen Chloride, Sulfur Dioxide, Chlorine Dioxide and Hydrogen Sulfide Gases. The cartridges are color coded white.

Organic Vapor/Acid Gas Cartridges are generally approved for Organic Vapors and Chlorine, Hydrogen Chloride, Sulfur Dioxide, Chlorine Dioxide and Hydrogen Sulfide Gases. The cartridges are color coded yellow.

If the areas of use for exposure of chlorine gas are separate and distinct from the use for exposure to organic vapors and vice versa, then you could select acid gas cartridges for exposure to chlorine gas and organic vapor cartridges for exposure to organic vapors. On the contrary, if exposure will be to both chlorine and organic vapors or you would like to consolidate to just one cartridge for exposure to chlorine gas and organic vapors, then you would select the organic vapor/acid gas cartridges. Most companies opt for selecting the organic vapor/acid gas cartridges since it will avoid confusion and consolidate to just one cartridge for inventory purposes.

If you have any additional questions, please let me know. Thanks!

All My Best,

Re: Respirator Cartridges: Single Purpose vs. Combination

Hello,
I am in the process of learning more about respirator cartridges. We are getting ready to make a large purchase (for us) of cartridges. We need some for use against chlorine and some organic vapor cartridges. I was wondering if there is a difference between using, say an acid gas cartridge vs. an acid gas/organic vapor cartridge.

Any help is greatly appreciated.
