Ceiling value: A concentration of a toxic substance in air that ACGIH recommends should not be exceeded at any time during the workday. ... Short-term Exposure Limit (STEL) value: A TWA concentration over 15 minutes that ACGIH recommends not to exceed--even if the 8-hour TWA is within the standards.
