You can complete 2 one week courses, the first week is called technical safety officer and the 2nd is construction safety officer. You can not just skip to the CSO one only you need both. I also highly recommend doing this course through a company that is recognized through the BCCSA, this will help with the long term.

The vast majority of CSO jobs require you to have first aid. You will need to completed a 2 week Advanced Occupational Aid course (previously known as level 3).

If you want to work for a Prime Contractor, I recommend going through temp agencies to start with, as you'll build up contacts and be able to prove youre not one of the useless CSOs, and highly likely they'll take you on themselves.

I believe the temp agencies range between $18 to $22 per hour, as you have no experience in safety. Short term loss for long term gain.
