Welding safety
I'll be honest, I know very little about welding other than it being a process that fuses metals together. From a safety professional standpoint, what are some "must-knows" about welding, and what should I be looking out for in the field?

This is rather open ended because of the potential environments and materials at play. Some stuff to consider:
- the environment: is it a confined space, is it loud, are there other hazards nearby (flammable material, moving machinery, etc.)
- the material: have to think about potential airborne exposure based on welding type and materials (CrVI, Mn, Ni, welding fume, gases)
- the controls: what PPE are they wearing, is local exhaust ventilation being utilized (and utilized appropriately)
- other hazards: UV exposure (PPE plays a part here), temperature, ergonomics
Best to remove paint and galvanized coatings from the areas that will be welded. Burned/vaporized paint is bad for you, lead and zinc are much worse.
The fire watch needs to remain at the job site at least 30 minutes after welding ceases. OSHA and I believe also NFPA requirement.
Welding fumes have been the big health issue & stainless has been a huge issue releasing hexavalent chromium but AIHA (I think) posted something last year that respiratory protection is now recommended for all welding fume. Also, most welders are knowledgeable that phosgene gas (toxic) is produced when brake cleaner is used prior to welding.
Ensure the welders are using proper PPE. For instance fall protection rated and tested for hot jobs like welding.
