FLUID JET IGNITION HAZARDS SAFETY ANALYSIS

摘要

The use of high-pressure abrasive fluid jets has caused concern among safety professionals due to the presence of sparks during the cutting operations on certain metals. These sparks were analyzed as to their size, velocity, and temperature, and compared against unclassified military formulas for ignition probabilities. As a further test of the probabilistic model, abrasive waterjet tests were conducted against steel, titanium, and zirconium targets in flammable gas environments.
