Poison Gas (Class 2.3) Storage
Division 2.3 materials are toxic gases that can be fatal or cause serious injury if inhaled. They often also carry flammability, oxidizer, or water-reactive secondary hazards.
Class, Division, and GHS meaning
DOT/UN Class 2 covers gases. Division 2.3 is the poison-gas division. A label like “Class 2.3, Division 5.1” means the primary transport class is poison gas, with an oxidizer subsidiary risk.
Storage implications for rental buildings
Store in gas-compatible hazmat buildings with robust ventilation planning, cylinder restraint, and separation from incompatible oxidizers, flammables, and occupied work areas. Confirm SDS exposure controls before selecting a rental unit.
