Subject: OHSA/NIOSH Permissible limits

Hello, all:

When the NIOSH pocket guide has different permissible limits (NIOSH versus
OSHA), which is the better one to follow?

For example, benzene's limit for NIOSH is 0.1 ppm (10 hr workday), while
OSHA's limit is 1 ppm (8 hour workday.)

Why the difference? From a legal perspective, which is a better choice?

Thanks in advance for any advice you might give; obviously, any advice
people might give is non-binding, you're not responsible, legal mumbo-jumbo,
blah, blah.

Cheers, Jim Tung
