A toxic vapor release is a hazard if there is potential for persons to be exposed to it. Toxic vapor release is defined in 4.42 for all tests with the exception of the crush test.

ERPG-2 defines this as: ″The maximum airborne concentration below, which it is believed that nearly all individuals could be exposed for up to one hour without experiencing or developing irreversible or other serious health effects or symptoms which could impair an individual’s ability to take protective action.″ See Section 11.Loss of protection controls – Failure of software and/or electronic controls, discrete control devices or other built-in electrical protection components relied upon for safety and that remain in the circuit during the test, to operate as intended
