Hazardous Location (HazLoc) Testing

With more than 20 years’ experience, F2 Labs can assist you with your hazardous location testing needs. We can perform the HazLoc product testing required to ensure that your product won’t cause a fire or explosion in an area where flammable or combustible materials (such as dusts, gases, fibers or vapors) are present. The product must be designed using various methods of protection.

F2 Labs has years of experience in U.S., Canadian, European, and other international standards and area classification of hazardous and non-hazardous locations. We can provide you with the assistance you need in order to navigate the hazardous location product certification process.

Hazardous Location Classes/Divisions for the US and Canada. They are categorized as follows:

Classes

The classes define the general nature of hazardous material in the surrounding atmosphere.

Class	Hazardous Material in Surrounding Atmosphere
Class I	Hazardous because flammable gases or vapors are present in the air in quantities sufficient to produce explosive or ignitable mixtures.
Class II	Hazardous because combustible or conductive dusts are present.
Class III	Hazardous because ignitable fibers or flying’s are present, but not likely to be in suspension in sufficient quantities to produce ignitable mixtures. Typical wood chips, cotton, flax and nylon. Group classifications are not applied to this class.

Divisions

The division defines the probability of hazardous material being present in an ignitable concentration in the surrounding atmosphere.

Division	Presence of Hazardous Material
Division I	The substance referred to by class is present during normal conditions.
Division II	The substance referred to by class is present only in abnormal conditions, such as a container failure or system breakdown.
