(iii) Based on the SM’s discussion with Worker X, assumptions were made about Worker X’s exposure to wood dust. Use the information in the OH’s report to show that these assumptions might be incorrect.

(ii) Now that the SM has the OH’s report (supporting document 4), they can draw further conclusions. Based on the information in the report, what was good about the approach taken by the OH?

(c) (i) Table 1 in supporting document 4 is an extract from the OH’s report. Calculate the 8-hour time-weighted average (TWA) exposure to wood dust for Worker X.

(b) Supporting document 2 suggests what an employer must consider when controlling exposure to hazardous substances such as wood dust. What approach must an employer consider when deciding how to control exposure to wood dust?

(iii) Explain the likely distribution of the wood dust in the respiratory tract of the workers exposed to the wood dust.

(ii) Explain the significance of the ‘typical exposure level’ reported in the study.

(i) Explain the meaning of ‘occupational exposure limits for wood dust that are assigned in law’.
