Ok, H2S Alive is a Oil patch course to teach about the dangers of H2S Gas, and it is a standard you must take to work in the oil patch only. Same with the PST (petroleum Safety Training) it is regional and industry specific training. The Oil Patch is where the money is. Working for BC Ambulance is not the route to go if you want to make money. Health & Safety is big business in the Oil patch and lots of companies and room to grow. You can do the PST online, and Whimis testing. H2S is a one day course in using Scott packs and rescue and Gas safety training. about $200.00.
And you might need to get a 1 day Occupational First Aid level 1 Course or equivalent as well and TDG (Transportation of Dangerous Goods) Class 4 license (what ever you use in the US to drive a ambulance or bus would be nice to.
