Target Audience:

En-Safe’s (1992) CH-02 Construction Heat Training, is approved by the Technical Standards and Safety Authority (TSSA Training Provider #000155415). CH-O2 certificate under Ontario Regulation 215/01 made under the Technical Standards and Safety Act, 2000, states that a person who is the holder of a CH-O2 certificate or the holder of a record of training for the purpose may activate a propane, natural gas or oil-fired construction heater or torch that has an input of 400,000 Btuh or less, and connect it to or disconnect it from piping, tubing, a refuelling appliance, a container or a natural gas meter.
