There's not as much difference as you say. The NJ page says
> New Jersey law (N.J.S.A. 34:5-182) requires that employers
provide workers with full-face air-purifying respirators when
engineering controls cannot be used. Use of respirators should
be part of a complete respiratory protection program.
While the CA page says
Respirators should only be used:
• As a last resort for
protection when local
exhaust ventilation or
water controls are not
feasible or do not
adequately control
employee airborne
exposures.
• Where exposures
exceed the permissible
exposure limit (50 μg/m3,
8-hour TWA) while installing or implementing feasible
engineering and work practice controls.
• When the employee is in a regulated area.
I.e., both say that other measures must be applied first.
