How long do you keep medical surveillance records?
30 years
Z-Test
statistical comparison between indoor / outdoor air samples during an AHERA
clearance. may allow for adjustment of clearance results
Minimum air volumes needed
25 mm filter = 1,199 liters of air
37 mm filter = 2,799 liters of air
What is breeching?
duct that transports combustion gases from a boiler or heater to chimney or stack. also
called a flue
