Hazardous Areas

What is a Hazardous Area?

Explosive atmospheres and their conditions.

A hazardous area is defined as an area in which an explosive atmosphere is present, or may be expected to be present, in quantities such as to require special precautions for the construction, installation and use of potential ignition sources.
An explosive atmosphere can be attributed to flammable gases, vapour and mists or combustible dusts being present through numerous operating processes. Major industries affected would include but not limited to:

  • Oil & Gas
  • Petroleum Refineries
  • Chemical Plants
  • Sewage Treatment
  • Grain Handling
  • Spray Painting Shops
  • Bakeries
  • Sugar Refineries
  • Aircraft Hangars
  • Petrol Stations

Eliminating Risk

Equipment designed to avoid ignition or explosion

An explosion will only occur when three basic conditions are present:

  • Explosive material / Fuel
  • Oxygen / Air
  • Sources of ignition

Remove any one of these basic conditions and an explosion will not occur.

  • I have engaged the services of Phil Lyon and HazElect on a number of electrical projects over a couple of years.  I have found Phil to be very professional, reliable and trustworthy with regards to providing excellent service as required by the contract requirements and making sure that his company employees provide the same standard of quality work which he provides.  I was also greatly impressed by Phil’s attention to detail as well as his proactive approach to identify options and solutions to challenges arising in any project.  On all the projects they completed for us, HazElect always met timely deadlines, most of them ahead of schedule and without compromising on quality and safety but still maintaining a fair price. Without any hesitation, I would definitely recommend HazElect to anyone seeking professional quality focused electrical services in the mining industry.
