Chemical Hazard Class and Storage Information

Dot Hazard Class  Definition  Examples Hazards  Storage 
(Also see Incompatible Chemicals)
 Class 1
Explosive/Shock Sensitive
 Thermodynamically unstable material picric acid, 2, 4- dinitro-phenol, organic azides Explosion caused by shock or chemical reaction.   Follow manufacture's recommendation. Discard before expiration date. Stores minimum quantities.
 Class 2: Gasses
Flammable Gasses
 Gas with a flash point less than 140° F  carbon monoxide, hydrogen, oxygen  Ignites easily, burns rapidly.  Store away from ignition sources and oxidizers. Secure with a double chain to prevent falling. Store oxygen away from flammable gases. Check connections regularly to avoid leaking.
 Non Flamable Gasses (including compressed gas)  Non-flammable, purified gas in a pressurized tank  nitrogen, carbon dioxide  Tank rupture, fire, toxic atmosphere, oxygen displacement  Store upright, secure with a double chain to prevent falling. Check connections regularly to avoid leaking.
 Class 3
Flamable Liquid
 Liquid with a flash point less 140° F  methanol, acetone, acetaldehyde  Ignites easily, burns rapidly.  Store in flammable storage cabinet, away from ignition sources and oxidizers. Quantities should not exceed 10 gallons.
 Class 4
Flammible Solid
 Solid that burns readily.  sodium  Ignites easily, burns rapidly.  Store in flammable storage cabinet, away from ignition source and oxidizers
  Class 5.1
Oxidizer
 Agents that react with reducible material to initiate or promote combustion.  nitric acid, bromine  Fire or explosion  Store away from organics and flammables. Do not store directly on wooden shelves or paper. Store chlorine separately from acids
 Class 5.2
Organic Peroxide
 Any organic compound that forms unstable peroxides when exposed to air.  diethyl ether  Explosion resulting from formation of concentrated peroxide crystals  Dispose before expiration date.  If there is no marked expiration date, label with receipt date and maintain for no more than 1 year or 6 months after opening.
 Class 6: Poison
Toxic
Highly Toxic
 Chemicals that cause damage to target organs (liver, lungs, reproductive system, etc.) if inhaled, ingested, or absorbed through the skin. Toxic chemicals have an LD50 of 50 - 500 mg/kg, single oral dose for rats. Highly toxic chemicals have an LD50 of < 50 mg/kg, single oral dose for rats.  chloroform, chromic acid, phenol, acetonitrile  Acute or toxic effects that may be local, systemic, or both.  Store in a secure, sealed container below shoulder level. Use only in designated areas.  Store away from incompatibles.
Class8: Corrosive
Organic Acid
 Compound with pH of 1-7, containing carbon.    Tissue damage, violent reaction with strong bases  Segregate from mineral acids, oxidizing acids and bases.
 Inorganic Acid  Compound with pH of 1-7, not containing carbon.  hydrochloric acid, sulfuric acid, boric acid  Tissue damage, violent reaction with strong bases.  Segregate from organic acids, oxidizing acids and bases.
 Caustics  Compound with pH of 7-14.  sodium hydroxide, potassium hydroxide  Tissue damage, violent reactions with strong acids.  Segregate from mineral acids, organic acids, and oxidizing acids.
 Class 9: Miscellaneous  Reacts violently when exposed to water producing heat or toxic gases.  sodium metal, acid anhydrides, metal anhydrides  Explosion, fire, toxic atmosphere  Store away from water, including sprinkler heads, sinks and drains, per manufacturers instructions.
 Water Reaction  Ignites spontaneously in air  Phosphorus, lithium  Fire  Store under inert atmosphere per manufacturers instructions.
  Pyrophoric  Ignites spontaneously in air  Phosphorus, lithium  Fire  Store under inert atmosphere per manufacturers instructions.
  Carcinogen  Chemicals that cause cancer in humans or animals models.  formaldehyde, benzene  Carcinogenesis  Store in a secure, sealed container below shoulder level.  Use in only designated areas with approved controls. Store away from incompatibles.
 Cryogen  Liquefied or solidified gases at low temperatures.  liquid nitrogen, dry ice  Tissue damage (frost bite), oxygen displacement, tank rupture  Store in approved containers. Store in well ventilated areas. (Do not store dry ice in cold rooms.)  Design transfer lines such that liquids cannot be trapped in a non-ventilated part of the system.
 Sensitizer  Substances that can cause an allergic reaction of the skin or respiratory system.  glutaraldehyde, isocyanates  Allergic reaction.  Store in secure container taking into account other hazards associated with the substance.
 Controlled  Substances  Substances specifically controlled by federal law.  narcotics  Theft  Store in a secure, locked location.  Maintain a current inventory.
 Non-Hazardous
