Compliant storage and rental solutions for Potassium Hydroxide (KOH). EPA, OSHA, and NFPA guidance for containment, segregation, and fire protection — with rental buildings matched to this material.
Potassium Hydroxide is an odorless, white or slightly yellow, flakey or lumpy solid which is often in a water solution. It is used in making soap, as an electrolyte in alkaline batteries and in electroplating, lithography, and paint and varnish removers. Liquid drain cleaners contain 25 to 36% of Potassium Hydroxide.
