Any company that is in any way involved with the handling, processing, producing, transporting, and/or storing of flammable and combustible gases and liquids, combustible solids, explosible powders/dusts, and/or reactive chemicals would require our process safety services.



The manufacture of semiconductor and printed circuit boards involves the use of various hazardous chemicals and materials or simply electronic chemicals. Semiconductor chemicals encompass semiconductor substrates, semiconductor processing chemicals, and semiconductor packaging materials. Semiconductor processing chemicals include bulk and specialty gases, wet chemicals, photoresists, thin film metals, and CMP slurries. These chemicals range widely in volume usage but have a common thread of high purity requirements.

The classes and chemicals include:

  • Bulk gases, including nitrogen, oxygen, argon, helium, and hydrogen;
  • Dopants gases, including arsine, phosphine, boron trichloride, boron trifluoride, and diborane;
  • Etchant gases, including boron trichloride, chlorine, chlorine trifluoride, hydrogen chloride, hydrogen fluoride, nitrogen trifluoride, silicon tetrafluoride, sulfur hexafluoride, tetra-fluoromethane, trifluoromethane, difluoromethane, fluoromethane, hexafluoroethane, pentafluoroethane, octafluoropropane, and octafluorocyclobutane;
  • Chemical vapor deposition (CVD) chemicals, including silane, dichlorosilane, trichlorosilane, silicon tetrachloride, disilane, tetraethylorthosilicate, silicon tetrafluoride, methyl-silane, germane, ammonia, nitrous oxide, and tungsten hexafluoride; and
  • Wet chemicals, including acetic acid, acetone, ammonium fluoride, ammonium hydroxide, hydrochloric acid, hydrofluoric acid, hydrogen peroxide, isopropyl alcohol, nitric acid, phosphoric acid, and sulfuric acid.

Electrostatic discharges (e.g., sparks, brush discharges) can also cause problems in the electronics sector where damage can be caused to sensitive electronic components. Control of static electricity requires special techniques over and above those used to prevent fire and explosion. Discharges from equipment, insulators, and even people can each cause damage to components, and identification of the sources of static charging as well as charge control techniques are needed.

We partner with our clients in the electronics industry to help them identify, assess, prevent, and control fire, explosion, and accidental loss of containment hazards in their operations. Our services include expert consulting, laboratory testing, and training in the specialist fields of dust explosion & fire hazards, electrostatic hazards & processing problems, gas & vapor flammability hazards, Process Hazard Analysis, Process Safety Management, and incident investigation.
