Silica Exposure Prevention

Silica is the second most common mineral found in the earth’s crust. It can be found in soil, sand concrete, masonry, rock, granite, landscaping materials, etc. However, when turned into dust, crystalline silica can be extremely dangerous to your health. Breathing in crystalline silica can cause silicosis, which can be disabling or even fatal. In some cases, it takes 15-20 years for the effects to take place. As silicosis progresses, one may experience shortness of breath and suffer poor oxygen/carbon dioxide exchange.

OSHA has established a set of standards to identify, reduce and eliminate health hazards in the work place with regards to silica exposure. To reduce exposure, employers and workers should abide by the following:

• Whenever possible, find an alternative to using silica.

• Use engineering and work factor controls to prevent exposure to silica (example: local exhaust vent)

• Use proper PPE when engineering and work factor controls cannot reduce silica exposure.

• Provide and attend proper safety training.

• Participate in monitoring and medical surveillance.

• Be aware of which operations and in which areas crystalline silica exposure is possible.

• Practice good housekeeping and hygiene.

• Wear disposable and washable clothes.

Always be mindful of the potential health hazards crystalline silica can cause. Be cautious of your environment and the work you are doing, and always let a supervisor know if you believe there is a threat of crystalline silica exposure.
