| Resumen |
In an effort to better characterise airborne fibre levels and types associated with the installation of residential insulation, airborne fibre concentrations were measured during the installation of several insulation products. Sample collection and fibre counting procedures followed NIOSH Method 7400 with some modifications. The arithmetic mean concentration of total airborne fibres during installation of batt-type insulation was 0.22f/cm3 (95% c.l.=0.18-0.27f/cm3). Significantly, approx. 20% were respirable glass fibres. For applications of blowing wool, the total airborne fibre concentrations were higher, with means of 1.0f/cm3 (0.9-1.1) or 2.1f/cm3 (1.5-2.7), depending on the product type. Glass fibres were 0.7f/cm3 (0.6-0.8) or 1.7f/cm3 (1.2-2.5) and respirable glass fibres were 0.3f/cm3 (0.2-0.4) or 0.8f/cm3 (0.5-1.3). Similar to the batt installation results, only 20-40% of the total airborne fibres were respirable glass fibres. The night after installation of the insulation was complete, the airborne fibre concentrations dropped to the levels measured before the insulation work began. |
