OSHA-Compliant Handheld Grinders
Handheld Grinders: OSHA-Compliant Dust Control Methods
Let’s Talk About Your Dust Collector...
How big does it need to be?
According to the rule above, your dust collector must provide 25 CFM for every inch of cutting blade. So if you’re using a 5-inch blade, you need a dust collector with at least 125 CFM. If you switch to a 7-inch blade, your dust collector must provide at least 175 CFM.
What about the filter?
OSHA’s new rule also requires that you use either
- a cyclonic pre-separator, which captures dust and debris and prevents it from clogging the filter of your dust collector; or
- a dust collector with a built-in filter-cleaning mechanism. That means that you cannot take out the filter and bang it against a trashcan to get rid of a clog. Your dust collector must have an internal mechanism that does that without exposing you or your team to dust.
What else do I need to know?
Full and proper implementation of dust collection systems on handheld grinders also requires the employer to ensure that:
- The shroud is intact and installed in accordance with the manufacturer’s instructions
- The hose connecting the tool to the vacuum is intact and without kinks or tight bends
- The filter(s) on the vacuum are cleaned or changed in accordance with the manufacturer’s instructions
- The dust collection bags are emptied to avoid overfilling
Let’s Talk About Respiratory Protection...
According to the rule above, respiratory protection is not required when using a water-based dust suppression system, regardless of task duration.
When dry dust collection systems are used, respiratory protection with a minimum APF of 10 is required, but only when engaged in a task indoors or in an enclosed location for more than four hours per shift.
