In a decision that is estimated to save over 600 worker lives every year,* the Occupational Safety and Health Administration, or OSHA, passed new legislation in 2016 that will limit worker exposure to crystalline silica dust. The construction industry was the most heavily impacted by the new legislation and was given a September 23, 2017 deadline for compliance. This decision is supported by the fact that silica is a known carcinogen and that 2 million of the 2.3 million workers exposed to silica dust are construction workers according to the Centers for Disease Control, or CDC. The same source also estimates that the new legislation will prevent more than 900 new cases of silicosis every year, which is the disease most closely associated with silica dust inhalation.
What can I do to minimize the dangers of silica dust inhalation?
The first step to reducing the amount of silica dust in the air is to following OSHA’s specific safety and health regulations, which vary depending on the equipment being used and the type of work being done. Additional silica dust safety best practices include:
Be aware of material containing silica.
Knowing which materials contain silica will help you avoid inhaling the dust when working with it. Crystalline silica is a naturally occurring mineral found in quartz. Products made from quartz that contain silica include:
Glass and ceramic material
Certain types of paint and coatings
Always wear the appropriate protective apparel.
Providing workers with the right personal protective equipment and apparel is a key part of preventing exposure to silica dust. Respiratory masks are a primary piece of safety equipment required by OSHA for work involving materials containing silica. Other suggested protective apparel includes:
Respirator masks are essential in preventing silica dust exposure
After the work is done, wash or dispose of the used protective equipment to prevent silica dust particulates from spreading.
Pay attention to the amount of time spent working around silica dust.
The more time you spend in areas where silica dust levels are high, the more you are exposing your lungs to particles that can cause silicosis and the other diseases listed above. OSHA has different dust extraction equipment requirements depending on whether a shift involving work on material containing silica dust is four hours or eight hours. For this reason, it is important to closely monitor the time each worker is exposed to silica.
Bonus tip: Do not allow your crew to consume food or beverages in areas with high silica dust levels. Make sure that breaks are taken away from areas where work is being conducted to limit additional exposure.
Communicate the hazards to your crew.
Communication is a critical part of preventing most hazards on the jobsite, including silica dust inhalation. Make sure your crew knows of the health risks associated with silica dust, which materials contain silica, and what type of work is more likely to create a risk of exposure. Developing a hazard communication plan and informing your crew of the dangers of dust inhalation could save someone’s life.
Bonus tip: Hang the appropriate safety markers and signage to indicate areas in which silica dangers are present, and permit access only to workers who are trained on silica dust safety.
What are the other diseases associated with silica dust?
In addition to silicosis, there are several other disease and health conditions that can as a result of long-term silica dust inhalation. These diseases range from mild to severe, with some being fatal illnesses. They include:
- Chronic renal failure
- Lung cancer
As mentioned above, taking the appropriate safety precautions is the key method for preventing all of the diseases associated with silica dust inhalation.
