OSHA Isocyanate Exposure Monitoring Log

Inspection template for documenting isocyanate exposure controls, supplied-air respirator use, and exposure monitoring in a paint or body shop environment.

Inspection Details

• Inspection date and time recorded
• Area inspected identified
  Document the specific paint booth, prep area, mixing room, or body shop location.
• Inspector name and role recorded
• Inspection trigger documented

Exposure Controls and Work Practices

• Spray application area controls are in place and functioning
  Verify local exhaust ventilation, spray booth operation, and containment measures are active during isocyanate-containing coating application.
• Mixing, spraying, and cleanup tasks are separated from non-essential personnel
  Confirm access control and work practices limit bystander exposure in the paint department.
• SDSs for isocyanate-containing products are available and current
  Safety data sheets should be accessible to employees and match the products in use.
• Mixing and application procedures follow the written SOP
  Check that the current work practice matches the approved procedure for product handling, spray application, and cleanup.
• Housekeeping prevents overspray, residue buildup, and secondary contamination
  Inspect surfaces, tools, and waste handling for visible residue or contamination that could increase exposure.

Supplied-Air Respirator and PPE Compliance

• Supplied-air respirator required for the task is being worn
  Confirm the correct respiratory protection is in use for spraying or other tasks with isocyanate exposure potential.
• Respirator fit, airflow, and hose connections are secure
  Inspect the supplied-air system for proper connection, airflow, and visible damage or leaks.
• Respirator inspection and cleaning records are current
  Verify pre-use checks, maintenance, and cleaning documentation are up to date for the respirator in service.
• Eye, skin, and body PPE are appropriate for the task
  Confirm gloves, coveralls, and eye protection are selected for isocyanate-containing materials and are in serviceable condition.
• Employees demonstrate correct donning and doffing sequence
  Observe whether workers remove PPE without contaminating skin, clothing, or clean areas.

Exposure Monitoring and Records

• Personal or area exposure monitoring has been completed as required
  Document whether monitoring was conducted for the task, shift, or employee group based on the exposure assessment plan.
• Monitoring results are below the applicable internal action level or exposure limit
  Record the measured concentration and compare it to the site exposure criteria or applicable occupational exposure limit.
• Sampling method, date, and employee/task sampled are documented
  Confirm the log includes the sampling method, duration, location, and task being performed.
• Employees notified of monitoring results and follow-up actions
  Verify communication of results, restrictions, and any required re-evaluation or corrective action.

Training, Medical Surveillance, and Corrective Actions

• Employees trained on isocyanate hazards and symptom reporting
  Confirm training covers respiratory sensitization, skin exposure, and reporting of coughing, wheezing, or breathing difficulty.
• Medical surveillance or evaluation referrals documented when indicated
  Record whether employees with symptoms or elevated exposure were referred according to site procedure and occupational health requirements.
• Corrective actions assigned with owner and due date
  Document deficiencies, responsible person, target completion date, and verification method.
