The TWA is given in dBA, and shows the exposure as an 8-hour day at a constant sound level rather than as a percentage of the maximum level allowed. For example, a 50% dose is equivalent to a TWA of 85 dBA. To convert from percentage dose (D) to TWA, the … WebACGIH lists a TWA of 1 ppm, and a STEL of 5 ppm. NIOSH sets a 10-minute ceiling of 10 ppm. Cal/OSHA marks a 10 ppm TWA; a 15 ppm STEL, and a 50 ppm ceiling.
