## Hazard class hubs
- [Poison Gas (Class 2.3) Storage](https://chemical.ushazmatrentals.com/hazard-classes/poison-gases): 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.
- [Flammable Gas (Class 2.1) Storage](https://chemical.ushazmatrentals.com/hazard-classes/flammable-gases): Flammable gases ignite easily in air and need ignition control, ventilation, and fire-rated or appropriately classified storage when quantities and codes require it.
- [Toxic / Poison (Class 6.1) Storage](https://chemical.ushazmatrentals.com/hazard-classes/toxic-class-6-1): Class 6.1 covers toxic substances that can cause serious harm through inhalation, ingestion, or absorption. Many also carry a subsidiary flammable or corrosive hazard.
- [Oxidizer (Class 5.1) Storage](https://chemical.ushazmatrentals.com/hazard-classes/oxidizers): Oxidizers can intensify fire or cause combustible materials to ignite more readily. They need strict segregation from fuels, solvents, and organic materials.
- [Dangerous When Wet (Class 4.3) Storage](https://chemical.ushazmatrentals.com/hazard-classes/dangerous-when-wet): Class 4.3 materials react with water to emit flammable gases. Moisture control and separation from water-based suppression assumptions are critical.
- [Flammable Solid (Class 4.1) Storage](https://chemical.ushazmatrentals.com/hazard-classes/flammable-solids): Flammable solids can ignite through friction, heat, or flame and often need fire-rated, dry storage with controlled ignition sources.
- [Corrosive (Class 8) Storage](https://chemical.ushazmatrentals.com/hazard-classes/corrosives): Corrosives attack metal, tissue, or both. Buildings need chemical-resistant containment and careful separation of acids, bases, and metals-sensitive inventories.
- [Flammable Liquid (Class 3) Storage](https://chemical.ushazmatrentals.com/hazard-classes/flammable-liquids): Flammable liquids (DOT Class 3 / GHS flammable-liquid categories) are the largest storage group in this database. Category numbers describe relative flash-point severity.
- [Unclassified & SDS-Confirmed Storage](https://chemical.ushazmatrentals.com/hazard-classes/unclassified): Some Chemical DB records have an empty, “N/A,” or incomplete hazard class. Treat the Safety Data Sheet as the authority and use storage guidance from flammability, compatibility, and fire-suppression fields.
