| Resumen |
The use of 4 and 10 air changes/h of general ventilation is studied. The general ventilation effect of local exhaust points in the vicinity of the dust sources is compared with the effect of general ventilation at an asbestos-cement pipe plant. For equal effectiveness of dust control, general ventilation is much more expensive than local exhaust ventilation. Local exhaust can provide far more effective dust control. Any effect of general ventilation is difficult to measure. Recommendations for reducing dust counts or contaminant concentrations are given: improved enclosure; increased amount and effectiveness of local exhaust ventilation; improved housekeeping and work practices; change of process and equipment. |
