Not in a refinery, or you have to buy weird/expensive non-sparking hammers and wedges. Aluminum bronze wedges are commercially available but the liability insurance is incredible so you're better off cutting your own (its a wedge, not a rocket engine...). It ends up being cheaper to use the expansive grout.
- dsfyu404ed 4y agoThis is exactly what I mean by "paying to get around process tech debt" Facility has a "no sparks" in buildings A, B and C rule. Rule obviously doesn't apply to contractors doing a ton of welding during a holiday shutdown. Non-contractors in maintenance dept want to fix some other crap at the same time. Sure they could try and get approval to use a jackhammer concurrent with the other work but in reality there's a 75% chance the safety department will intentionally stonewall until after the shutdown rather than set the precedent of a sensible exemption and the maintenance manager knows it so they buy the expensive grout.

So you'd need to do something like have the safety officer personally responsible for removing the jackhammer from the premises. Or renting it, perhaps.
