Protection Factors for Respirators

Question 1

Air purifying respirators are good for

Answer 1

Particles only

Question 2

The highest protection factors all have

Answer 2

Pressure demand (positive pressure) or continuous flow

Question 3

Air purifying respirators - highest PF

Answer 3

Facepiece full, or hood , positive pressure = 1000

Question 4

Air-line - highest PF

Answer 4

Facepiece, full continuous flow =1000Facepiece, full Pressure Demand = 1000Hood, continuous flow = 1000

Question 5

SCBA - highest PF

Answer 5

Facepiece, full, Pressure Demand = 10,000Facepiece, full, Pressure Demand, recirculating = 10,000
