OSHA has the legal standing.

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
