Hazardous Location Guide

Hazardous Locations?

Hazardous locations are defined as areas where dangerous concentrations of flammable gases, vapours, or dusts may occur. Products designed for hazardous locations have to meet the ever increasing CSA and ULC standards and regulations.

Hazardous area products fall into two categories:

  • They prevent an explosion by restricting the amount of energy entering the device (intrinsically safe)
  • They have a strong housing to contain an internal explosion (explosion proof) or survive in a harsh external environment (corrosion proof).

PRODUCT CATEGORIES

Intrinsic Safety

Intrinsic Safety is a protection technique which ensures safe operation of electrical equipment used in hazardous areas. These electronics are specifically designed to limit the electrical and thermal energy to ensure they stay below the point of ignition of the atmospheric mixtures present (flammable gases or dust).

Automation and Controls

There is a wide range of automation and control products that are suitable for use in hazardous locations. A variety of Modular controllers exist depending on the complexity of your application in addition to distributed I/O systems that can help with modular designs and scalability.

Connectivity Solutions

Certain hazardous environments require explosion proof or ATEX-rated connectors for code compliance and to ensure safety of personnel and equipment.

Motors

Siemens rugged explosion-protected motors are certified for hazardous location atmospheres containing dust and/or gas according to UL and CSA requirements or ATEX requirements.

Process Instrumentation

Process Instruments are often installed in areas classified as hazardous according to CSA, IEC or NEC. Such projects have certain challenges including the design phase, components selection, installation, and regular maintenance.

Video Cameras

These IP video cameras are designed for locations classified as hazardous and can be used when video surveillance is required.

Enclosures and Signaling

These enclosures are able to contain explosions originating within and to prevent sparks from igniting vapours/gases and/or dust in the surrounding environment. Hazardous Location Signaling Devices are designed to alert you to critical equipment and system needs on the plant floor.

Heating Solutions

Specific electric heating equipment can be used safely in hazardous areas to protect pipes, valves, tanks and equipment but certain precautions must be taken to remove the risk of fire and explosions.

Lighting Solutions

Explosion Proof Lighting is also known as Hazardous Location Lighting or Intrinsically Safe Lighting. These lights are designed for use in environments where flammable vapours and/or dust exist or have the potential to exist.
