Acrylonitrile Awareness Training Online
Acrylonitrile awareness training built around 29 CFR 1910.1045 (General Industry), meeting the OSHA training requirements for workers exposed to acrylonitrile. Covers the 2 ppm PEL, 1 ppm action level, 10 ppm ceiling, and OSHA-required medical surveillance. Self-paced, instant certificate.
What Is Acrylonitrile Awareness Training?
Acrylonitrile awareness training teaches workers about the hazards of occupational acrylonitrile exposure — a probable human carcinogen whose acute toxicity resembles cyanide poisoning. The training covers OSHA's 2 ppm PEL, the 1 ppm action level, the 10 ppm ceiling, medical surveillance for employees exposed at or above the action level, and safe work practices. Required under 29 CFR 1910.1045 for general industry. HazMat Student's awareness course is $19.95.
The Federal Regulatory Framework for Acrylonitrile
OSHA enforces acrylonitrile exposure under 29 CFR 1910.1045 for general industry. OSHA sets a 2 ppm PEL, a 1 ppm action level, and a 10 ppm ceiling not to be exceeded in any 15-minute period. NIOSH publishes a more protective Recommended Exposure Limit (REL) of 1 ppm (TWA, Ca) in its Acrylonitrile Topic Page. NIOSH classifies acrylonitrile as a potential occupational carcinogen (Ca) and recommends a more protective 1 ppm REL.

Acrylonitrile Exposure Limits at a Glance
All limits below are enforceable under 29 CFR 1910.1045(c). The action level — not the PEL — is what triggers the full set of monitoring, surveillance, and training obligations.
OSHA 29 CFR 1910.1045 and the NIOSH Pocket Guide to Chemical Hazards (acrylonitrile, CAS 107-13-1).
A dual hazard — cancer and cyanide-like acute toxicity
Acrylonitrile is unusual: it is a probable human carcinogen AND an acute poison whose mechanism resembles cyanide, capable of causing collapse and death from a single high exposure. Workers must be protected against both the long-term cancer risk and the immediate asphyxiant danger — which is why OSHA pairs a 2 ppm PEL with a hard 10 ppm 15-minute ceiling.

Engineering Controls and PPE for Acrylonitrile Exposure
OSHA's hierarchy of controls applies to acrylonitrile exposure: engineering controls first, work practice controls second, PPE last. The selections below match the requirements in 29 CFR 1910.1045(g).
Ventilation and Engineering Controls
Engineering controls are the first line of defense against acrylonitrile vapor.
- Closed-system transfer and sampling to prevent vapor release
- Local exhaust ventilation at emission and loading points
- Enclosure of high-emission process steps
- Routine leak detection and system-integrity checks
Respiratory Protection
Respiratory protection is used when engineering controls cannot keep exposures below the PEL.
- APR: Air-purifying respirators with organic-vapor cartridges where permitted by the exposure assessment
- SAR: Supplied-air respirators for higher or uncertain exposures
- SCBA: SCBA for emergency, IDLH, or unknown-concentration entries
- Respirator selection follows the employer's written respiratory protection program (29 CFR 1910.134)
Dermal Protection and Monitoring Instruments
Liquid acrylonitrile is hazardous on skin contact — dermal protection is required, not optional.
- Chemical-resistant gloves and suits rated for acrylonitrile — no skin contact with the liquid
- Eyewash and quick-drench stations where liquid contact is possible
- Photoionization detector (11.7 eV lamp) for field screening; NIOSH Method 1604 for compliance sampling
- Routine area and personal sampling against the 1 ppm action level
Acrylonitrile Medical Surveillance Program
Under 29 CFR 1910.1045(n), employers must provide a medical surveillance program to workers exposed to acrylonitrile. The program below summarizes the federal requirements that this course covers in depth.

Real-World Acrylonitrile Training Scenarios
These composite scenarios show how acrylonitrile awareness training fits real compliance situations across the industries that handle it.
🧶 The Acrylic Fiber Line Restart
An acrylic fiber plant brings a polymerization line back online after maintenance and needs the crew current on acrylonitrile hazards before they handle monomer transfer.
What's at Stake — Missing Acrylonitrile Training Is Expensive
Under OSHA's current penalty schedule (effective January 15, 2025), employers can be cited up to $16,550 per serious violation per worker, with willful or repeat violations multiplied to $165,514. Acrylonitrile citations carry weight because recognized by employers and contractor pre-qualification systems nationwide — and carries its own substance-specific OSHA standard with exposure monitoring, regulated areas, and medical surveillance. For complete penalty details, recent enforcement examples, and the FY 2026 schedule from OSHA, see our OSHA Penalty Schedule reference and osha.gov/penalties.
Six Common Acrylonitrile Training Mistakes
The most common compliance gaps we see with acrylonitrile awareness:
1. Treating HazCom as a substitute
Assuming general Hazard Communication training covers acrylonitrile-specific requirements.
Fix: Acrylonitrile has its own standard (1910.1045) with a specific PEL, action level, ceiling, regulated areas, and medical surveillance — beyond generic HazCom.
2. Ignoring the skin-contact route
Focusing only on inhalation and overlooking that liquid acrylonitrile is dangerous on skin contact.
Fix: The standard specifically addresses potential skin or eye contact with liquid acrylonitrile; train on dermal protection, not just respiratory.
3. Confusing the ceiling with a STEL
Treating the 10 ppm limit as a 15-minute average that can be balanced out across the shift.
Fix: It is a ceiling — it must never be exceeded during any 15-minute period, even if the 8-hour average is fine.
4. Skipping the action-level triggers
Not realizing that reaching the 1 ppm action level triggers monitoring, medical surveillance, and training.
Fix: Track exposures against the 1 ppm action level and act on the triggers it sets in motion.
5. Letting training lapse
Treating the course as one-and-done.
Fix: Training is required at initial assignment and at least annually thereafter.
6. Underestimating acute toxicity
Viewing acrylonitrile only as a long-term cancer risk and not as an acute poison.
Fix: Acute exposure can cause cyanide-like collapse and death; emergency response must reflect that immediacy.
