Calculation of the simultaneous exposure index for "All tasks" for inhalable, respirable, and RCS dusts

Chemical agent	Agent (i)	OELV 8h mg/m3	Results (TWA) mg/m3 (all work tasks) (Ei)	$\frac{E_i}{{\text{OELV}}_i}$
Inahalable dust	1	10	12.08	1.21
Respirable dust	2	3	0.88	0.29
RCS	3	0.025	0.004	0.16
