Benzene Air Testing and Exposure Assessment (OSHA 1910.1028)
Benzene is one of the most tightly regulated carcinogens in industry. Midwest IHS provides CIH‑led benzene air testing and exposure assessments for manufacturing, refineries, laboratories, chemical handling operations, and emergency response situations. Our monitoring supports OSHA 1910.1028 compliance and helps protect employees from acute and chronic health risks.
OSHA Benzene Standard Requirements (1910.1028)
OSHA requires employers to evaluate benzene exposure when employees may be exposed at or above:
- Action Level: 0.5 ppm (8‑hour TWA)
- PEL: 1 ppm (8‑hour TWA)
- STEL: 5 ppm (15‑minute)
If exposures exceed the action level, employers must implement:
- Initial and periodic air monitoring
- Medical surveillance
- Respiratory protection
- Engineering and administrative controls
- Employee training
- Hazard communication updates

FAQ – Benzene Air Testing & OSHA Compliance
Q: When is benzene air testing required?
A: When employees may be exposed at or above 0.5 ppm (action level) during their shift.
Q: What sampling method is used for benzene?
A: NIOSH 1501 charcoal tube sampling analyzed via gas chromatography.
Q: How often must benzene monitoring be repeated?
A: Every 6 months if exposures exceed the action level; annually if below.
Q: Do you provide CIH‑led benzene assessments?
A: Yes. All benzene monitoring is performed or overseen by a Certified Industrial Hygienist.
Q: Can benzene be detected with real‑time instruments?
A: Yes, PIDs can screen for benzene, but lab‑confirmed sampling is required for OSHA compliance.
