If you're a contractor or facility manager, you know that dust containment is more than just a matter of cleanliness. It's about safety, efficiency, and profitability.
What is Silica?
Silica is a common mineral found in materials like sand, stone, concrete, and bricks. When these materials are cut or ground down, they release tiny particles of silica into the air - particles small enough to be breathed in deep into your lungs.
Why Should Contractors Care About Silica?
If you're exposed to high levels of silica dust over time, it can cause permanent lung damage. And if you already have a respiratory condition like asthma or COPD, exposure to silica dust can make it worse - potentially life-threateningly so.
What Does The New Rule Say?
The old rule said that workers could be exposed to no more than 100 micrograms of crystalline silica dust per cubic meter of air over eight hours without needing to take extra precautions. The new rule cuts that limit in half, to just 50 micrograms.
How Do You Control Silica Dust?
Controlling silica dust requires a combination of engineering controls, administrative controls, and personal protective equipment (PPE). Here are some key strategies:
Use wet cutting methods instead of dry ones whenever possible. Wet cutting reduces the amount of dust generated by up to 90%.
What About Other Dust Containment Best Practices?
Controlling silica dust is just one part of a comprehensive dust containment strategy. Here are some other best practices to consider:
Use HEPA-filtered vacuums designed specifically for capturing small particles like silica.
