Hazardous Locations

Hazardous LocationsThere’s no need to “live dangerously” when in a hazardous location. Careful planning helps you stay safe, instead. When planning your hazardous location job, you need to know:

  • The terrain. Your work might be in an unclassified location, but maybe you need walk through a Class III location to get to it. Or maybe part of the system you’re working on is in a Class II location. The Class X difference alone may not affect a Confined Entry Permit and what you must do to make it applicable to both the work area and the transit route to it; but different chemical (or other hazards) may exist in these different areas.
  • The hazardous substances. Read each MDS that applies to hazardous materials in the work location and in any areas you must walk past or through to get to it. Read the rules for dealing with spills or other problems related to  those materials.
  • Which tools. Which tools can you not use in the work area? Which tools will you need to use instead, to do the same work? This also applies to test equipment and communications gear.
  • Where the emergency things are. This includes fire exits, emergency eye washes, and emergency showers.
  • When is the best time. There may be operational/process reasons why entering at one time is much safer than entering at another.

The hazard controls. What must you do to prevent ignition, reduce exposure to hazardous substances, etc.?
