Silica Dust Monitoring Inspection Checklist [FREE PDF]

Crystalline silica exposure is a leading cause of occupational lung disease, including silicosis, lung cancer, and COPD. OSHA's Respirable Crystalline Silica Standard (29 CFR 1926.1153 for construction and 29 CFR 1910.1053 for general industry) mandates exposure assessment, engineering controls, and medical surveillance when workers may be exposed at or above the action level of 25 µg/m³ TWA. Consistent monitoring and documentation are essential to protect workers and demonstrate regulatory comp

  • Industry: Industrial Hygiene
  • Frequency: Quarterly
  • Estimated Time: 45-60 minutes
  • Role: Industrial Hygienist
  • Total Items: 35
  • Compliance: OSHA 29 CFR 1910.1053 - Respirable Crystalline Silica (General Industry), OSHA 29 CFR 1926.1153 - Respirable Crystalline Silica (Construction), OSHA 29 CFR 1910.134 - Respiratory Protection, NIOSH REL: 0.05 mg/m³ TWA for Respirable Crystalline Silica, ACGIH TLV-TWA: 0.025 mg/m³ for Respirable Crystalline Silica (Quartz)

Exposure Assessment & Initial Evaluation

Verify that initial and periodic silica exposure assessments are conducted and documented per regulatory requirements.

  • Has an initial exposure assessment been completed for all tasks with potential silica exposure?
  • Are exposure assessments repeated whenever a change in production, process, control equipment, or work practice may result in new or additional exposures?
  • Have objective data or performance-oriented options been documented as an alternative to air monitoring where applicable?
  • Are all exposure assessment records retained for at least 30 years?
  • Have affected employees been notified of their individual exposure results within 15 working days?

Air Monitoring Procedures

Confirm that air sampling methods, equipment, and frequency meet regulatory and NIOSH methodological standards.

  • Is personal air sampling being used as the primary method for measuring respirable crystalline silica?
  • Are sampling pumps calibrated before and after each sampling event?
  • What is the measured TWA concentration of respirable crystalline silica (µg/m³)?
  • Are sampling results analyzed by an accredited laboratory (e.g., AIHA-accredited)?
  • Are area (ambient) air samples collected in addition to personal samples to identify source locations?

Engineering & Administrative Controls

Evaluate the effectiveness and maintenance of engineering controls used to reduce silica exposure at the source.

  • Are engineering controls (e.g., local exhaust ventilation, wet methods) implemented as the primary means of exposure reduction?
  • Is wet suppression or water delivery used on silica-generating equipment and maintained in functional condition?
  • Are local exhaust ventilation (LEV) systems inspected and maintained per manufacturer specifications?
  • Are dry sweeping and compressed air blowdown prohibited for cleaning silica-contaminated surfaces?
  • Are housekeeping procedures documented and enforced to minimize silica dust accumulation in the work area?

Respiratory Protection Program

Verify that respiratory protection is correctly selected, used, and maintained when engineering controls alone cannot achieve compliance.

  • Is a written respiratory protection program (RPP) established and implemented per OSHA requirements?
  • Are workers who use respirators medically evaluated and cleared by a licensed healthcare professional before use?
  • Have all respirator users been fit-tested for the specific make, model, and size of respirator they use?
  • Is the minimum assigned protection factor (APF) of the respirator appropriate for the measured silica exposure level?
  • Are respirators stored properly to protect against damage, contamination, and deformation when not in use?

Medical Surveillance Program

Confirm that medical surveillance is provided to workers exposed at or above the action level and records are maintained per OSHA requirements.

  • Are workers exposed at or above the OSHA action level (25 µg/m³ TWA) for 30 or more days per year enrolled in medical surveillance?
  • Are initial medical examinations offered within 30 days of enrollment in the medical surveillance program?
  • Do periodic medical examinations include chest radiographs, pulmonary function testing, and symptom questionnaires?
  • Are medical records maintained for the duration of employment plus 30 years?
  • Are medical examination costs covered by the employer at no cost to the employee?

Hazard Communication & Training

Verify that silica hazard communication, safety data sheets, and worker training meet OSHA requirements.

  • Are Safety Data Sheets (SDS) for silica-containing materials accessible to all workers in the work area?
  • Have workers received silica-specific training on health hazards, exposure limits, and control measures at the time of initial assignment?
  • Are training records documenting employee participation retained and available for OSHA inspection?
  • Are containers of silica-containing materials labeled with GHS-compliant labels including hazard pictograms and signal words?
  • Are written silica exposure control plans posted or accessible in areas where silica work is performed?

Program Documentation & Corrective Actions

Review overall program documentation completeness and verify corrective actions from previous inspections are closed.

  • Is a written silica exposure control plan maintained and updated at least annually?
  • Have all corrective actions from the previous silica monitoring inspection been completed and verified?
  • Are current monitoring results compared against NIOSH REL (0.05 mg/m³) and ACGIH TLV (0.025 mg/m³) in addition to OSHA PEL?
  • Are photographs or site sketches of silica hazard areas documented in this inspection record?
  • Please document any additional observations, overexposure incidents, or program deficiencies identified during this inspection.
