Does It Impact You?

The biggest question for most companies is “How do I know if I’m affected?” The most basic way is by utilizing your company’s Material Safety Data Sheet (or MSDS) to see what percentage of different materials are being used. If you see that your welding wire contains greater than 0.1% cadmium, chromium, lead, or nickel or greater than 1.0% manganese, then your company could apply to these regulations.  From here, if your company is involved in over 50% or more total labor in the following categories you will need to comply to Rule 6x: electrical and electronic equipment finishing, fabricated metal products, fabricated plate work (usually in boiler shops), fabricated structural metal manufacturing, heating equipment (minus electric), industrial machinery and equipment finishing, iron and steel foraging, primary metal products manufacturing, and valve and pipe fittings.  Processes that are impacted by the rule are as follows: dry abrasive blasting (3 types), dry grinding, dry polishing with machines, dry machining, spray painting (two types), and most importantly welding.
