If You Work in an Area Where These Are Present: | Then Use This Type of Forklift. |
Hazard Classification | Acceptable Forklift Designations |
Class I Flammable gases or vapors are or may be present in quantities sufficient for explosion or ignition | Division I Condition exists continuously, intermittently, or periodically under normal operating conditions. | Division II Condition may occur accidentally e.g., puncture of a storage drum. |
- Acetylene
- Cyclopropane
- Ethylene oxide
| - Acetaldehyde
- Diethyl ether
- Isoprene
| - Butadiene
- Ethylene
- Propylene oxide
| Forklift use prohibited | DY, EE, EX(also DS, ES, GS, LPS) if the only exposure is sealed containers or liquefied or compressed gases in containers |
- Hydrogen (or gases or vapors equivalent in hazard to hydrogen, such as manufactured gas)
- Unsymmetrical dimenthyl hydrazine (UDMH).

| EX | DY, EE, EX(also DS, ES, GS, LPS) if the only exposure is sealed containers or liquefied or compressed gases in containers |
Class II - Combustible dust is present
| Division I Explosive or conductive mixture may be present under normal conditions or where equipment failure can lead to both this condition and arcing or sparking. | Division II Explosive mixture not normally present but where deposits of dust may cause heat rise in electrical equipment |
- Aluminum, magnesium, and their commercial alloys
- Other metals of similarly hazardous characteristics
| Forklift use prohibited | Forklift with electrical enclosures manufacturer approved where magnesium, aluminum or aluminum bronze may be present. |
- Carbon black,
- Coal or coke dust
| EX | Forklift manufacturer approved for this location. |
| | EX | DY, EE, EX |
Class III Easily ignitable fibers or flyings are present but not likely to be in suspension in quantities sufficient to ignite. | Division I Locations in which these materials are handled, manufactured or used. | Division II Locations in which these materials are stored or handled (other than manufacture) |
- Baled waste
- excelsior
- jute
- sisal
- tow
| - cocoa fiber
- hemp
- kapok
- Spanish moss
| - cotton
- istle
- oakem
- synthetic fibers
| DY, EE, EX | DS DY ES EE EX GS LPS (Type E may continue to be used if used previously at this location.) |
Unclassified Locations Piers and wharves inside and outside general storage, general industrial or commercial properties. | D, E, G, LP (more protective designations may also be used) |
