?? Primary Regulated Chemical Hazards

Workers in this industry are routinely exposed to the following substances governed by OSHA 29 CFR 1910.1000 Table Z-1 and specific substance standards:

Chemical Name Primary Toxicological Hazard Action
Toluene-2,4-Diisocyanate (TDI) Severe respiratory sensitizer, occupational asthma View Exposure Limits →
Methyl Ethyl Ketone (MEK) CNS depression, rapid solvent flash vaporization View Exposure Limits →
Trichloroethylene (TCE) Carcinogen, solvent neurotoxicity, renal damage View Exposure Limits →
Xylenes Ototoxicity, vapor inhalation toxicity View Exposure Limits →

?? Required Engineering Controls

Under OSHA hierarchy of controls, ventilation and enclosure must be prioritized prior to relying on respiratory protection:

Down-draft spray booths, LEV with face velocity >= 100 fpm, explosion-proof ventilation.

?? Governing OSHA Standards

Federal standards directly enforceable by OSHA compliance officers during unannounced inspections:

  • ? 29 CFR 1910.1000 Table Z-1
  • ? 29 CFR 1910.1026 (Hexavalent Chromium)
  • ? 29 CFR 1910.134 (Respirators)
