Flammable Liquid Storage Requirements for Class 1A, 1B, 1C
Posted by Safe & Vault on Jun 19, 2015
Flammable liquids are defined by OSHA as any with a flashpoint below 100 F. They are defined in three classes. Many of these liquids have storage requirements in flammable liquid storage cabinets. Depending on the safety requirements and compliance of your local OSHA jurisdiction, certain class flammable liquids may need Securall flammable safety cabinetsthat are designed for cans, drums, chemical storage and more.
CLASS 1A – Flash point below 73 F, boiling point below 100 F and could require OSHA approved safety cabinets that meet flammable liquid storage compliance requirements.
