Inadequate dry chemical agent can be dangerous, whether that be due to unacceptable chemical composition or moisture content. Several standards require dry chemical agent be analyzed periodically:

  • NFPA 10 Portable Fire Extinguishers 2018 Ed. 7.8.3.4.2 requires that dry chemical be thoroughly checked before it can be re-used. This includes checking for proper type and contamination.

  • NFPA 17 Dry Chemical Extinguishing Systems 2017 Ed. 11.3.1 requires examination of dry chemical at least twice a year and after any system activation for a non-pressurized system. Section 11.3.1.2 requires examination of dry chemical in pressurized systems to be done at least every six years.

  • IMO 1432 31/5/2012 requires dry chemical agent in fixed dry chemical systems be tested for moisture content every two years.

  • OSHA 29 CFR 1910.161(b)(4) requires sampling of the dry chemical agent in all but stored pressure systems at least annually to ensure it is free of moisture.

• Moisture Content

  • High moisture content can lead to caking of the agent, resulting in inadequate flow of the agent through the equipment, and/or corrosion of the storage vessel, potentially compromising its integrity.

• Chemical Composition

  • A chemical composition other than that listed with the equipment and hazard may not work as designed. Mixing of different types of agents can lead to a chemical reaction that produces byproducts of water (increasing agent moisture content) and carbon dioxide (increases vessel pressure to dangerous levels).
