Not to rain on 02sled self back patting but Level 1 and 2 JOHSA is like a 4 day session, you learn next to nothing other than 'this is the manual and this is how you read it" " this is a form and this is how you fill it out"
he claims level 2 so he knows all about everything, well you learn your environment and his is an office building a far cry from what construction would be in this case. So he learned about filling out maybe an air quality form and not much more.
ASk me how I know no really don't ask
