Limit values short term exposure

The threshold limit value—time integrated average, TLV—TWA, of chlorine dioxide is 0.1 ppm, and the threshold limit value—short-term exposure limit, STEL, is 0.3 ppm or 0.9 mg /m of air concentration (87,88). Chlorine dioxide is a severe respiratory and eye irritant. Symptoms of exposure by inhalation include eye and throat irritation, headache, nausea, nasal discharge, coughing, wheezing, bronchitis, and delayed onset of pulmonary edema. Delayed deaths occurred in animals after exposure to 150—200 ppm for less than one hour. Rats repeatedly exposed to 10 ppm died after 10 to 13 days of exposure. Exposure of a worker to 19 ppm for an unspecified time was fatal. The ingested systemic effects of low concentration chlorine dioxide solutions are similar to that of chlorite.

Threshold Limit Value Short-Term Exposure Limit (TLV-STEL) was also developed by ACGIH and represents the concentration to which workers can be exposed continuously for a short period of time without suffering from (1) irritation, (2) chronic or irreversible tissue damage, or (3) narcosis of sufficient degree to increase the likelihood of accidental injury, to impair self-rescue, or to materially reduce work efficiency and provided that the daily TLV-TWA is not exceeded. 

TLV-STEL, threshold limit value short-term exposure limit, concentration. This time-weighted 15-minute average exposure should not be exceeded at any time during a workday even if the TLV-TWA is within limits. Intended as supplement to TLV-TWA. 

Threshold Limit Value—Short-Term Exposure Limit—Ceiling. The concentration that should not be exceeded during any part of the working exposure. 

The ACGIH TLV-STEL (Threshold Limit Value — Short Term Exposure Limit ACGIH, 2001) is defined as a 15-min TWA exposure which shouldnotbe exceeded at any time during the workday even if the 8-h TWA is within the TLV-TWA. E q)osures above the TLV-TWA up to the STEL should not be longer than 15 min and should not occur more than four times per day. There should be at least 60 min between successive exposures in this range.

TLV-STEL Threshold limit value, short-term exposure hmit is the maximum concentration averaged over a 15-min period to which healthy adults can be exposed safely. Exposures should not occur more than four times a day, and there should be at least 60 min between exposmes. 

Uhen inhalation concentrations were determined based on a TWA (Tiioe Weighted Average) work day, the total exposure concentrations were less than 0.1 yg/m> TWA established (DREW, NIOSH 77-159, 11.01). When determined based on actual application time, exposure on 29 September of 0.205 yg/m was the largest recorded. The Threshold Limit Value-Short Term Exposure Limit (TLV-STEL) ( ) for diazinon is reported as 0.3 yg/m . Thus, based on the STEL, the exposure levels were below the 0.3 yg/m . 

TLV-STEL (Threshold Limit Value - Short-Term Exposure Limit ) is the maximum concentration of a substance which a worker may be exposed over a continuous 15 minute period with a low probability of experiencing irritation, irreversible damage, or unconsciousness. Four of such 15-minute periods are allowed per workday of 8 hours, with at least a 60-minute break between them. However, at no time may the TLV-TWA be exceeded. In the case of any exposure, which is above TWA yet below STEL should be clearly specified so. However, in any case such exposures should be for no longer than 15 minutes at any one time or no more than 4 times per day .

Threshold Limit Value/Short-Term Exposure Limit (TLV-STEL). The concentration of a substance to which workers can be continuously exposed for up to 15 minutes at a time, four times a day, every day, without adverse effects. Threshold Limit Value/Time Weighted Average (TLV-TWA). The average concentration of a substance to which workers can be continuously exposed for eight hours a day, five days a week, without adverse effects.
