620 OSHA Forklift Certification | OSHAcademy Online Training

To select the right forklift for each hazard class and division location, open the tables below.

Look in the first column of the table for the hazard class of the material.
Find the row that has the chemical or substance handled.
Choose the second or third column based on the division that represents the exposure condition.

Table for Class I Hazard Classifications, Division I Locations, and Division II Locations

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 Acetaldehyde Butadiene Cyclopropane Diethyl ether Ethylene Ethylene oxide Isoprene Propylene oxide Hydrogen (or gases or vapors equivalent in hazard to hydrogen, such as manufactured gas) Unsymmetrical dimenthyl hydrazine (UDMH)	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.
Acetone Acrylonitrile Alcohol Ammonia Benzine Bensol Butane Ethylene dichloride Gasoline Hexane Lacquer Solvent Natural gas Naphtha Propane Propylene Styrene Xylenes Vinyl acetate Vinyl chloride	EX	DY, EE, EX (also DS, ES, GS, LPS) if the only exposure is sealed containers or liquefied or compressed gases in containers.

Table for Class II Hazard Classifications, Division I Locations, and Division II Locations

Hazard Classification	Acceptable Forklift Designations
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 arching 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.
Other combustible dusts	EX	DY, EE, EX

Table for Class III Hazard Classifications, Division I Locations, and Division II Locations

Hazard Classification	Acceptable Forklift Designations
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).
