Silicosis Prevention

April 5 - April 6

To protect yourself from possible exposure to respirable crystallinesilica you must prevent the creation of silica-laden dust. Use
power tools that are designed to keep the point of operation
(cutting blade, drill bit, etc.) wet. Another option is to use HEPA
(high efficiency particulate air) filter equipped power tools. In order
for these tools to function properly, the user must maintain and
use the tools according to the manufacturer’s instructions
(maintain required water flow, change the filters at specified
intervals, etc.). If these options are not available, you will probably
have to wear a respirator to protect yourself from this hazard.
The OSHA standard establishes an occupational permissible
exposure limit (PEL) of 50 micrograms per cubic meter of air,
based upon an 8 hour time weighted average exposure for an
employee. To give you some idea of how small 50 micrograms per
cubic meter of air is, consider this; it is equivalent to ¾ of a
teaspoon of respirable silica in the volume of a football field that is
64,000 cubic yards!
