SCHEDULE 1
The time-weighted average exposure of a worker to coke oven emissions shall be calculated for a forty-hour week and an eight-hour day as follows:
1. The average concentrations of coke oven emissions to which a worker is exposed shall be determined from analyses of air samples representative of the exposure of the worker to coke oven emissions during work operations as set out in the Code mentioned in section 11.
2. The results of the analyses are the concentrations expressed as BSFTPM of coke oven emissions in milligrams per cubic metre of air.
3. The concentrations shall be multiplied by the time in hours to which the worker is taken to be exposed to such concentrations.
4. The weekly exposure shall be calculated as follows:
C1T1 + C2T2 +...+ CnTn = cumulative weekly exposure
where,
C1 is the concentration found in an air sample, and
T1 is the total time in hours to which the worker is taken to be exposed to concentration C1 in a week.
5. The weekly time-weighted average exposure shall be calculated by dividing the cumulative weekly exposure by 40.
6. The daily exposure shall be calculated as follows:
C1T1 + C2T2 +...+ CnTn = cumulative daily exposure
where,
C1 is the concentration found in an air sample, and
T1 is the total time in hours to which the worker is taken to be exposed to concentration C1 in a day.
7. The daily time-weighted average exposure shall be calculated by dividing the cumulative daily exposure by 8.
