Silica Dust Monitoring Inspection Checklist [FREE PDF]

Crystalline silica exposure is regulated under OSHA 29 CFR 1910.1053 for general industry, requiring employers to assess worker exposures, implement engineering controls, and maintain medical surveillance programs. The permissible exposure limit (PEL) for respirable crystalline silica is 50 µg/m³ as an 8-hour TWA, with an action level of 25 µg/m³. Consistent monitoring and documentation are essential to protect workers from silicosis, lung cancer, and other silica-related diseases.

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, OSHA 29 CFR 1910.134 Respiratory Protection, OSHA 29 CFR 1910.1020 Access to Employee Exposure and Medical Records, NIOSH REL for Crystalline Silica (0.05 mg/m³ TWA), ACGIH TLV for Respirable Crystalline Silica (0.025 mg/m³ TWA)

Exposure Assessment & Monitoring Program

Verify that air monitoring protocols meet OSHA 1910.1053 requirements for assessing worker exposure to respirable crystalline silica.

Has an initial exposure assessment been conducted for all silica-generating tasks?
Have personal air sampling results been obtained within the required monitoring interval?
Is sampling performed using NIOSH-approved analytical methods (NIOSH 7500 or 7602)?
What is the most recent measured 8-hour TWA concentration (µg/m³)?
Are monitoring records retained for at least 30 years per OSHA requirements?

Engineering Controls & Ventilation

Assess the adequacy and maintenance status of engineering controls designed to minimize silica dust generation and airborne concentrations.

Are wet suppression systems in place and operational at all silica-generating operations?
Is local exhaust ventilation (LEV) installed at all identified silica dust generation points?
Are LEV systems inspected and maintained at least annually with records documented?
Have substitution controls been evaluated to replace crystalline silica materials with safer alternatives?
Are vacuum systems used for dust cleanup equipped with HEPA filtration?

Respiratory Protection Program

Confirm that a written respiratory protection program is in place and that workers are provided appropriate respirators when engineering controls are insufficient.

Is a written respiratory protection program (RPP) maintained and current?
Are workers using respirators with an assigned protection factor (APF) adequate for measured silica concentrations?
Have all respirator users received a medical evaluation before initial use?
Have all respirator users completed annual fit testing with the specific respirator model used?
Are respirator inspection, cleaning, and storage procedures followed per manufacturer and OSHA requirements?

Medical Surveillance Program

Evaluate the medical surveillance program for workers exposed to crystalline silica at or above the action level for 30 or more days per year.

Are all eligible workers enrolled in the medical surveillance program per OSHA 1910.1053?
Have initial medical examinations been completed within 30 days of initial assignment?
Are periodic medical examinations conducted at least every three years for eligible workers?
Are medical records maintained for the duration of employment plus 30 years?
Are written medical opinions provided to workers and employer following each examination?

Hazard Communication & Worker Training

Confirm that employees are informed of silica hazards and trained on protective measures as required by OSHA standards.

Are Safety Data Sheets (SDS) available and accessible for all silica-containing materials?
Have all silica-exposed workers completed training on health hazards and protective measures?
Are warning signs posted in areas where silica exposures may exceed the PEL?
Are training records including dates, content, and attendee signatures maintained?
Have workers been informed of their exposure monitoring results in writing?

Written Exposure Control Plan (ECP)

Review the written exposure control plan for completeness, accessibility, and accurate reflection of current site conditions.

Is a written Exposure Control Plan (ECP) established and site-specific?
Is the ECP reviewed and updated at least annually or when tasks or controls change?
Is the ECP readily accessible to all affected employees and their designated representatives?
Does the ECP include a list of all job tasks involving silica exposure with assigned controls?
Are housekeeping practices for silica-contaminated areas documented in the ECP?

Recordkeeping & Program Audit

Audit the completeness and accuracy of all silica program records and identify any gaps requiring corrective action.

Are all exposure monitoring records organized and indexed by employee, job task, and date?
Have any OSHA violations related to silica been cited in the past 3 years?
Are corrective actions from previous silica audits documented and tracked to completion?
Has the effectiveness of engineering controls been verified through post-control air monitoring?
Please document any additional observations, deficiencies, or recommended corrective actions.
