Class 1 Hazardous Locations refer to facilities which deal with flammable gases, vapors, and liquids. Division 2 specifies that these flammable materials are handled, processed, or used in the defined hazardous location, but are not normally present in concentrations high enough to be ignitable.
Simply put, this requires proper handling and storage of the flammable gases, vapors, or liquids to prevent such an ignition under normal operating conditions. This also might involve a positive mechanical ventilation system that prevents any ignitable concentration from forming, and absent any breakdown of the ventilation equipment, the concentration of the flammable gases or liquid-produced vapors will never reach an ignitable level.
LITELUME’s Class 1 Division 2 LED Lighting solutions are robust, durable industrial luminaires engineered for indoor and outdoor hazardous locations and high particulate areas such as granaries, mills, and mines, locations with gasoline vapors like gas stations, airplane hangars, or auto shops, and environments where petrochemical vapors exist.
According to Wikipedia, In electrical and safety engineering, hazardous locations (HazLoc) are places where fire or explosion hazards may exist. Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable.
Electrical equipment installed in such locations could provide an ignition source, due to electrical arcing, or high temperature. Standards and regulations exist to identify such locations, classify the hazards, and design equipment for safe use in such locations.
This is why it’s extremely important to make sure your light fixtures are certified for these dangerous locations. LITELUME specializes in manufacturing these fixtures. For more information, contact us today at (833) 533-5863 or email us at firstname.lastname@example.org.
These areas are defined as those in which flammable gas, dust, or vapors are present in the air. The quantities may be so small but sufficient to produce a fire and explode. Some Class 1 environment areas can include:
In North America, the hazardous location classification system was created by the National Fire Protection Association. As the world trade of electrical products and services continues to grow, international standards are converging so that more and more acceptable techniques get approved by regulatory agencies. OSHA (Occupational Safety and Health Administration) is the agency that enforces regulations to make sure we comply.
Hazardous Locations are classified by the likelihood of an ignitable concentration of combustible material being present. There are two systems in place, including the traditional North American Division system as well as the alternative Zone system. See below for further details:
Division 1 – Ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors can exist under normal operating conditions.
Division 2 – Ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are not likely to exist under normal operating conditions.
Class I – Flammable gases, flammable liquid-produced vapors, and combustible liquid-produced vapors
Class II – Combustible dusts
Class III – Ignitable fibers/flyings
Class I locations are those in which flammable vapors and gases may be present.
Class II locations are those in which combustible dust may be found.
Hazardous Location Groups – Materials are further divided into Groups for Class I, Divisions 1 and 2:
A – Acetylene
B – Hydrogen
C – Ethylene
D – Propane
E – Metal Dusts (Div. 1 only)
F – Carbonaceous Dusts
G – Non-Conductive Dusts (flour, grain, wood, plastic, etc.)
What is the difference between a Class I, Division 1 Location and Class I, Division 2 Location? What about the differences between the other locations?
Class I, Division 1 Location
Ignitable concentrations of flammable gases, vapors or liquids: can exist under normal operating conditions; may exist frequently because of repair or maintenance operations or leakage; or may exist because of equipment breakdown that simultaneously causes the equipment to become a source of release.
Volatile flammable liquids or flammable gases or vapors exist, but are normally confined within closed containers; Ignitable concentrations of gases, vapors or liquids are normally prevented by positive mechanical ventilation; or Adjacent to a Class I, Division 1 location where ignitable concentrations might be occasionally communicated.
Ignitable concentrations of combustible dust can exist in the air under normal operating conditions;Ignitable concentrations of combustible dust may exist because of equipment breakdown that simultaneously causes the equipment to become a source of ignition; or electrically conductive combustible dusts may be present in hazardous quantities.
Combustible dust is not normally in the air in ignitable concentrations;
Dust accumulations are normally insufficient to interfere with normal operation of electrical equipment; dust may be in suspension in the air as the result of infrequent malfunction of equipment; or dust accumulation may be sufficient to interfere with safe dissipation of heat or may be ignitable by abnormal operation.
A location in which easily ignitable fibers or materials producing combustible flyings are handled, manufactured or used.
A location in which easily ignitable fibers are stored or handled other than in the process of manufacture.
