Ensuring Safety in Hazardous Locations: A Guide by WorkSite Lighting

At WorkSite Lighting, we prioritize safety in hazardous locations by offering certified, high-quality equipment tailored to your needs. This guide, inspired by Intertek’s Hazardous Locations and Explosive Atmosphere Guide, highlights essential protection methods, certifications, and standards.

 

What Are Hazardous Locations?

Hazardous locations are areas with explosive gases, vapors, or combustible dusts that pose significant risks. Examples include:

  • Oil and Gas Facilities: Refineries, pipelines, and offshore rigs.
  • Chemical Processing Plants: Handling flammable liquids or gases.
  • Agricultural Sites: Grain silos and feed mills prone to combustible dust.

Explore our products tailored to meet these challenges.

Key Protection Methods for Hazardous Locations

Effective protection methods prevent ignition and ensure safe operation. These include:

1. Intrinsic Safety (Ex i)

How It Works: Limits energy within electrical circuits to prevent sparks or high temperatures.

Applications: Handheld devices, sensors, and communication equipment.

2. Explosion-Proof Enclosures (Ex d)

How It Works: Contain internal explosions and prevent flames from escaping.

Applications: Lighting fixtures and motors.

3. Encapsulation (Ex m)

How It Works: Seals components in protective resin to block hazardous materials.

Applications: Electronics like transformers and relays.

4. Pressurization (Ex p)

How It Works: Maintains positive pressure inside enclosures to keep hazardous substances out.

Applications: Control panels and electrical cabinets.

UL Standards for Hazardous Locations

Understanding UL standards is critical for ensuring your equipment meets North American safety requirements. Here are key UL standards:

Standard Description Application
UL 1203 Explosion-Proof and Dust-Ignition-Proof Electrical Equipment Used for Class I, Division 1 environments.
UL 674 Electric Motors and Generators Designed for hazardous atmospheres.
UL 844 Lighting Fixtures for Hazardous Locations Applies to explosion-proof and dust-tight lighting.
UL 913 Intrinsically Safe Equipment Ideal for low-energy circuits in hazardous locations.

Zones and Equipment Protection Levels (EPLs)

Hazardous locations are classified into zones based on the likelihood of explosive atmospheres:

Zone Description EPL Required
Zone 0 Continuous explosive atmosphere Very High (Ga)
Zone 1 Likely during normal operations High (Gb)
Zone 2 Unlikely or short-duration presence Low (Gc)
