Such exposures might cause reversible effects, such as mild skin or eye irritation, but they are not expected to Impair judgment or interfere with proper responses to emergencies.

The SMAC reports will also be applicable to the space shuttle, because the recommended SMACs will cover the exposure times that are of interest to the space-shuttle program i-fur and 24-hr SMACs for emergencies and 7-day and 30-day SMACs for continuous exposures.
