APPENDIX 2 - TEST AEROSOL CERTIFICATION

2.1

SPECIFICATIONS

Substances used as test aerosols for quality assurance testing at FTFs shall be DOE approved

(see 2.5.).

2.2

HEALTH AND SAFETY

2.2.1

Toxicity

Studies shall be performed or validated to show that use of test aerosols present no

unacceptable occupational risk when used to perform the tests specified herein. The

studies must consider the expected exposure pathways (skin absorption, inhalation)

and the fate of the inhaled material in terms of material transfer, residence times,

critical organs, and results.

Toxicity assessments should consider quantities and concentrations of

materials and exposure pathways which approximate realistic occupational or

accidental exposure.

2.2.1.1

Engineering Design as Alternative to Toxicity Testing. When toxicity

testing has not been performed, or toxicity test results are inconclusive,

candidate test aerosols can be used in FTFs if compliance with the following

requirements has been demonstrated.

Engineering design and construction is adequate to prevent test aerosols

from contaminating breathing air in the FTF (aerosol confinement).

Engineering design and construction of exhaust air handling systems is

adequate to minimize quantities of test aerosols released to the

surrounding environment.

Applicable exposure limits (concentration guidelines) are established as

maximum concentrations for breathing air within the FTFs and for

exhaust air from exhaust stacks.

Air sampling or monitoring programs are adequate to determine

compliance with the above exposure limits.
