?? 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
Benzene Group 1 Carcinogen, Acute Myeloid Leukemia (AML) View Exposure Limits →
Hydrogen Sulfide (H2S) Olfactory fatigue, sudden respiratory paralysis (IDLH 100 ppm) View Exposure Limits →
n-Hexane Peripheral polyneuropathy, motor axon damage View Exposure Limits →
Sulfur Dioxide Severe bronchoconstriction, acid gas inhalation View Exposure Limits →

?? Required Engineering Controls

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

Closed-loop sampling stations, vapor recovery units (VRU), automated emergency shutdown valves (ESD).

?? Governing OSHA Standards

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

  • ? 29 CFR 1910.1028 (Benzene Standard)
  • ? 29 CFR 1910.119 (PSM)
  • ? 29 CFR 1910.120 (HAZWOPER)
