  1. Fulltext. Estimation of exposure from spilled glutaraldehyde solutions in a hospital setting.

    Article - En anglais


    Glutaraldehyde is commonly used in hospitals for cold disinfection of instruments which may be damaged by autoclaving.

    The increased use of automatic washer/disinfection machines has resulted in a greater risk of spills than with manual methods.

    A series of experiments was conducted to answer two related research questions : what was the likely range of airborne concentrations when glutaraldehyde is spilled, and are commonly used personal protective equipment ensembles effective and practicable in use ?

    Objective measurements using three sampling methods (two pumped methods based on OSHA 64, one using treated filters and the other based on adsorbent tubes, and a Glutaraldemeter direct reading instrument) were conducted with spills of various surface areas of both 2 and 50% solutions of glutaraldehyde.

    Results ranged between<0.01 and 1.4 ppm.

    Two personal protective equipment ensembles were tested.

    One was based on a half-facepiece respirator with gas-tight goggles, while the other comprised a full-facepiece cartridge respirator.

    Both ensembles gave adequate protection against irritation, although in use the half-facepiece respirator and goggles tended to interfere with each other.

    The direct reading instrument generally underestimated the glutaraldehyde concentrations, although there was a significant association with the results obtained using the method based on adsorbent tubes.
