Cleaning Products, Chemistry & WHMIS

Cleaning chemicals are a tool — but a tool that can hurt you. This course covers what each product actually does, the dilution math, the chemistry of what NOT to mix (bleach + ammonia can kill), the universal dwell-time rule, and how to read a Safety Data Sheet. Builds on the WHMIS lessons in Workplace Safety Basics but applies specifically to cleaners.
