Protecting people is at the heart of every strong safety culture. Silicosis—an irreversible lung disease caused by inhaling respirable crystalline silica dust—is preventable when organizations take thoughtful, proactive steps to reduce exposure. By controlling dust at the source and empowering workers with the right tools and training, organizations can create safer environments where teams feel informed, prepared and supported.
Primary prevention strategies
Engineering controls (most effective)
Engineering controls are the first and strongest line of defense. Their goal: keep silica dust out of the air so workers don’t breathe it in.
- Wet methods: Use water delivery systems during cutting, grinding, drilling, or crushing to keep dust from becoming airborne.
- Local exhaust ventilation (LEV): Attach dust collection systems to tools to capture dust right at the source.
- Enclosures: Use enclosed equipment cabs to separate workers from dusty environments.
- Substitution: Replace highsilica materials—like sandblasting sand—with safer alternatives such as metal shot, aluminum oxide, or granulated plastic.
Administrative controls
Strong administrative practices reinforce a culture where every employee understands their role in maintaining a safe workplace.
- Housekeeping: Avoid dry sweeping or compressed air; use High Efficiency Particulate Air (HEPA) filtered vacuums or wet sweeping.
- Training: Provide clear, comprehensive training on silica hazards, safe practices and proper PPE.
- Signage: Mark areas where silica may be present.
- Access control: Limit time spent in highdust areas and restrict unnecessary access.
Personal protection and hygiene
When engineering and administrative controls aren’t enough, personal protective equipment adds an important final layer.
- Respiratory protection: Wear NIOSH-certified respirators (N95 or higher). Workers must be clean-shaven to ensure a proper seal.
- Hygiene practices: Avoid eating, drinking, or smoking in dusty areas and wash hands and face before doing so.
- Clothing: Use disposable or washable work clothes and change before going home to prevent bringing dust with you.
Surveillance and compliance
Consistent monitoring and medical evaluations help ensure controls are working and workers remain protected.
- Air monitoring: Measure exposure levels regularly.
- Medical exams: Provide chest x-rays and lung function tests for exposed workers.
- Regulatory compliance: Follow OSHA Standard 29 CFR 1926.1153 requirements for exposure limits and control plans.
