Three <strong>of</strong> the four mixerloaders found the protective gloves uncomfortable to<br />

wear. However, all four believed that their hands were being protected. Some<br />

experienced difficulty in gripping equipment when wearing the gloves, and<br />

two pairs <strong>of</strong> gloves had to be replaced because <strong>of</strong> abrasion or splitting. Workers<br />

found the face shields comfortable to wear; no misting <strong>of</strong> the visors occurred.<br />

The mixerloaders had no difficulty in keeping the face shields on during the<br />

work periods. There were some complaints <strong>of</strong> reflection from the white<br />

garments onto the face shields.<br />

Health surveillance<br />

No clinical signs or symptoms <strong>of</strong> intoxication by methamidophos were<br />

reported or observed in anyone involved in the study. Although there were<br />

slight variations in cholinesterase activity in blood samples from workers<br />

during the study, all values were within normal ranges.<br />

Discussion<br />

Cotton protective garments <strong>of</strong> the design used in this study were comfortable<br />

to wear in hot and humid climates. They showed little deterioration over the<br />

period <strong>of</strong> use and provided as much or more protection from the organophosphorous<br />

insecticide than the synthetic materials.<br />

When the benefits <strong>of</strong> availability and general low cost are taken into account,<br />

cotton has major advantages as a material for protective garments required by<br />

pesticide workers in tropical climates. Further investigation into the protective<br />

properties <strong>of</strong> cotton, i.e., variations in weight, thickness, and weave, would be<br />

worthwhile.<br />

The design <strong>of</strong> the protective garments was intended to provide some degree<br />

<strong>of</strong> flexibility under field conditions. For example, workers are able to wear the<br />

top and trousers separately or together over their normal work clothing<br />

depending on the kind <strong>of</strong> work they are engaged in. Although this design is<br />

recommended by the Working Group, it may not be acceptable esthetically in<br />

all cultures and other designs may be more appropriate for some types <strong>of</strong><br />

pesticide application. However, the general principle <strong>of</strong> the design proved to<br />

be successful in this study.<br />

Nitrile rubber gloves, although somewhat uncomfortable, can be worn by<br />

mixerloaders in hot and humid conditions and are, therefore, suitable for<br />

handling pesticide concentrates under these conditions. The simple face shield<br />

used in this study is also recommended.<br />

The opportunity was taken during the study to seek the workers' opinions<br />

about acquiring and wearing gloves and face shields in normal practice.<br />

Commitment to wearing these protective items varied, even if they were made<br />

readily available. This type <strong>of</strong> response is common (Jeyaratnam 1982) and<br />
