17、essed as a 15-min time-weighted average exposure which shall not be exceeded at anytime over a working day, except for substances which cause immediate irritation upon short exposure.3.2.2 occupational exposure limit XXXXX, “generic”the maximum time weighted time-weighted average (TWA) concentra-tio

19、 Occupational Exposure Limitoccupational exposure limit is not exceeded. Exposuresabove the Occupational Exposure Limitoccupational exposure limit up to the STEL should not be longer than 15 min 15 min andshould not occur more than 4four times per day. The minimum interval between these exposures sh
20、ould be 60 min.3.2.3.1 DiscussionThe phrase “nearly all workers” only excludes those who are hyper-sensitivehypersensitive to substance exposure or who haveknown medical conditions which may be aggravated by substance exposure.Thus, most workers are included in the group in whichno adverse health ef
21、fects are expected. The phrase “a normal 88- to 10 h 10-h workday, 40-h workweek” refers to the type of workbeing done, that is, what is usually done from one week to the next or one day to the next. It does not refer to length of workingtime as being the major consideration.The following specified
22、periods of time must be addressed either by determining a value or by stating the “time” is notaddressed:a) workday (number of hours specified)(1) Workday (number of hours specified),(2) Workweek (number of hours specified),(3) Lifetime (that is, cumulative), and(4) Very short-term maximum (for exam
