Although exposure measurements show that the stress caused by plant-protective agents is mostly below health risk values and although world-wide less toxic agents are under development, there still remains a risk for the farmer's health and welfare. So it is still a challenge to minimize this remaining risk. The wearing of protective clothing is one possibility. Requirements for each single protective element can be defined from the level of exposure, the toxicological data of agents and the legally stipulated limit values (e.g. NOEL, ADI or other TLV's). This is also valid for other requirements of protective measures like mechanical stability and thermal comfort. For all types of requirements test procedures must be defined to ensure that the given limit values will not be exceeded.
