The main one is other workers working in the same area, this means that you need to use containment sheeting or a shade cloth around where you are blasting. This protects other workers from getting showered with abrasive.
In flammable areas you need to make sure you keep your solvent safe, make sure it doesn’t flash off and cause an explosion. Typically clothes and disposable overalls need to be fire retardant (FR Rated).
Often there are some regulations around the connection of hoses and testing of blast hoses. Often we find that the contractors are certified QP1 or QP2 contractors. There are newer certifications from SSPC which certify the company and the workers onsite, we always recommend that facilities use qualified contractors to do work, they are far more efficient.
Site Access Contraints
Often you need lower height equipment so you can get the equipment underneath pipe racks. Need to ensure you tie off all your blast hoses so that when you’re blasting they don’t drag around or damage anything on the pipe racks, they need to be properly supported throughout.
