I have a curiosity question. We seem to have significantly differing past experiences within a group of colleges with respect to whether respiratory protection has been required to keep exposures below action levels when chemically cleaning, moving or stacking lead bricks. At some institutions, there's a rule of thumb (based on previous monitoring) that handling as few as 5 bricks requires full face respirators. Others say they have monitoring data where they've manipulated hundreds of bricks with no issues. So I'm curious if there's anyone out there with experience you would care to share.
