  2. Equipment Installation - Cactus employs certified gas fitters to ensure all odorization equipment is installed in compliance with existing codes.

The Canadian Standards Association has the following regulations in place regarding the use of odorants: "Fuel gas that is to be delivered to customers through distribution lines, or to residences associated with a compressor station, and that does not naturally possess a distinct odor to the extent that its presence in the atmosphere is readily detectable at all concentrations not less than one-fifth of the lower explosive limit, shall have an odorant added to it to make it so detectable, except that odorization shall not be necessary for such gas delivered for further processing or use where the odorant would serve no useful purpose as a warning agent. Fuel gas to be used within compressor stations shall be so odorized or electronic gas detectors that set off an alarm at a gas concentration of one-fifth of the lower explosive limit or less shall be used.
