What do you call "wireless anti-stat bracelet"? I can't really imagine such a thing.
Neither do I clearly see how to ground a squirt bottle. Is there a conductive deformable plastic?
I never saw a solvent ignited by a static discharge, but didn't use them all the day neither. If it were just for me at home, I'd say "overkill", sure. Especially as grounding everything is quite uncomfortable at a workplace.
- If you believe static discharges are a worry, begin by installing an antistatic floor. This wastes no operation time, doesn't go against comfort and efficiency. If your workers experience static discharges, this is the solution, and it will be accepted happily. If no-one experiences static discharges, I'd do nothing.
- Your solvents are easily flammable, this implies that they're volatile. I'd worry more about inhaling the vapours regularly than about a hypothetical fire risk. Did you check how unhealthy these vapours are? Can you find solvents as efficient (this is a condition for the workers or managers to accept them) that are little volatile?
- There are probably dozens of ignition sources at the work benches that are more credible than static discharges. Electric switches for instance.
