New ISO standard improves protective clothing for agricultural farmers and workers using pesticides
A new ISO standard on protective clothing will help farmers and agricultural workers to reduce job-related risks when using liquid pesticides.

Pesticides are commonly used in farming against pests, diseases and weeds. Depending on the toxicity and the use scenario they pose health risk if users do not wear adequate protective clothing. The new ISO standard defines specific protection levels. It allows pesticide manufacturers to indicate on the product label the required level of protection needed. It allows garment manufacturers to produce, certify and sell protective clothing with defined protection levels. It allows farmers and agricultural workers to buy and use protective clothing according to the pesticide manufacturers us e requirements.

The new ISO 27065:2011, Protective clothing – Performance requirements for protective clothing worn by operators applying liquid pesticides, addresses the protection of farmers and workers mainly during the application phase of pesticides, i.e. the work phase where most operator contamination occurs.

The standard deals with performance requirements of protective clothing materials, seams, and garments and defines three levels of protective clothing with specified resistance to penetration by pesticide products:

Level 1: The potential risk of contamination is relatively low. The performance requirements for level 1 garments have been developed in view of low spray drift landing on the operator, e.g. from tractor boom sprayers
Level 2: the potential risk of contamination is higher but not so high as to require the use of liquid-tight materials
Level 3: the potential risk of contamination requires use of garments made with liquid-tight materials. This level is suitable for high-exposure scenarios where it has been determined that garments that prevent liquids from penetrating/permeating provide adequate protection.

The standard will help test laboratories, fabric and garment manufacturers, manufacturers of pesticide products, trainers, regulators to make decisions regarding protective clothing for protection against pesticide products.

Helmut Eichinger, Chair of ISO/TC94/SC 13, comments, "ISO 27065:2011 will help pesticide users to be better protected and improve quality and performances of protective clothing, as well put safer protective clothing on the market. It will also contribute to reducing the risk to occupational health for operators and workers who use liquid pesticides.”
