Q

What type of HEPA vacuum is required when doing Abrasive Blasting or Sandblasting?

A

HEPA vacuum local exhaust: All exhaust air must be passed through a HEPA filter, with the area placed under negative pressure (at least 10 air exchanges per minute. Fresh air should be provided to the containment zone at a lower rate than the exhaust airflow to maintain the negative pressure zone.

Q

Equation for calculating MUC

A

MUC = PEL x PF
For half-respirator:
50 micrograms/m3 x 10 = 500 micrograms/m3
For full-face respirator:
50 micrograms/m3 x 50 = 2,500 micrograms/m3
PAPR/SAR
50 micrograms/m3 x 1000 = 50,000 micrograms/m3
