Abstract

The use of sprayed flammable fluids as solvents in dissolution and cleaning processes demands a detailed understanding of ignition and fire hazards associated with these applications. When it is not feasible to inert the atmosphere in which the spraying process takes place, then all possible ignition sources must be eliminated. If operators are involved in the process, the potential for human static build-up and ultimate discharge is finite, and nearly impossible to eliminate.
