Operator exposure levels and evaluation of different coverall performance

15

idence for reducing the operator exposure

levels during application of plant protection

products.

Moreover, in the present study, the com-

parison of the PDE and ADE values for the

A1-A5 and B1-B5 operator groups can be

used as a measure of PPE performance in

terms of coverall penetration, which can be

expressed as:

% penetration = 100 x ADE /PDE

From the aforementioned exposure

data, the average penetration for Type A

coverall is 0.79%, while for Type B coverall is

2.76% showing that the average Type B cov-

erall penetration is 3.5 times higher than the

respective one of Type A. It is noteworthy

that this difference in coverall performance

is in accordance with the results of previous

work addressing spray gun greenhouse ap-

plications, where Type B coverall was found

to be 3.5 times more permeable than Type

A. This difference in coverall performance

becomes evident under relatively high ex-

posure conditions, while no significant dif-

ferences are observed in low exposure sce-

narios (8). However, both coverall types

provided satisfactory protection under the

conditions of the specific trials.
