Do you know that 29 CFR 1910.106, OSHA’s regulation for Flammable Liquids, stipulates a storage requirement for water-reactive materials?
29 CFR 1910.106(d)(7)(iv) states that “Materials which will react with water shall not be stored in the same room with flammable liquids“. There is a letter of interpretation from 2003, which further clarifies that even if flammable liquids are stored within approved flammable storage cabinets; these materials should still not be stored within the same room. OSHA and the National Fire Protection Association (NFPA) have established that the storage of these materials in the same area creates an unreasonable hazard and risk.
It would be prudent to check the storage location of the water-reactive materials present at your site to verify that you are not in violation of 29 CFR 1910.106(d)(7)(iv).
