Understanding Hazardous Location Ratings: Division 1 vs. Division 2

When selecting lighting for hazardous environments, the most critical factors are the Class (the type of hazard) and the Division (the frequency of the hazard). Using an incorrectly rated tool can be a major safety violation and a fire hazard.

The Division Breakdown

The "Division" tells you how often the explosive or flammable material is expected to be present.

Rating	Definition	Hazard Frequency	Requirement
Division 1	High Risk. Flammable gases, vapors, or dust are present under normal operating conditions.	Constant or Frequent	Must use Intrinsically Safe or Explosion-Proof tools (like the 2004HZL).
Division 2	Potential Risk. Flammable materials are only present under abnormal conditions (like a leak or spill).	Infrequent or Accidental	Standard industrial tools may be prohibited; safety-rated tools are highly recommended.

The Three Classes of Hazards

Hazardous locations are further categorized by the specific type of material present:

• Class I (Gases & Vapors): Locations where flammable gases or vapors are present in the air (e.g., Petroleum refineries, gas storage, or spray finishing areas).
• Class II (Combustible Dusts): Locations where combustible dust is present (e.g., Grain elevators, coal plants, or flour/sugar mills).
• Class III (Ignitible Fibers): Locations where easily ignitible fibers are present, but not likely to be in suspension in the air (e.g., Textile mills or wood processing plants).

Why "Intrinsically Safe" Matters

A tool labeled "Intrinsically Safe" (like the Milwaukee 2004HZL) is designed so that it cannot produce enough electrical or thermal energy to ignite a specific hazardous atmospheric mixture. Even if the tool is damaged or short-circuited, it will not create a spark or heat up enough to cause an explosion.

Pro Tip: Always check the "Groups" listed on your tool. Groups A-D cover gases like Acetylene and Gasoline, while Groups E-G cover dusts like Metal, Coal, and Grain. The Milwaukee 2004HZL is rated for Groups A through G, covering the widest range of hazards.

Which Light Do You Need?

1. If you work in a refinery, fuel tank, or grain silo: You likely need a Division 1 rated tool.
2. If you work in a warehouse near sealed chemicals: A Division 2 rating may be sufficient, but many safety officers require Division 1 as a universal precaution.
3. If you work in general construction: Standard TRUEVIEW™ LED lights (like the M18™ ROVER™) provide the best visibility but are not rated for explosive atmospheres.
