Description
Use Permea-Tec Glove Sensors to detect toxic chemicals such as pesticides, aromatic amines, and isocyanates to detect break through in gloves and protective clothing. Wide variations in the chemical resistance of gloves and protective clothing compositions make protective equipment selection difficult—especially if using mixtures of chemicals in the workplace. Many factors affect the performance of gloves during actual use. Flexing, stretching, pressure and abrasion are physical factors that can cause premature breakthrough and bring into question reliance on ASTM Laboratory breakthrough data. PERMEA-Tec™ sensors show when breakthrough actually occurs and enables the safety professional to select the glove that is best suited for the job in terms of protection, employee acceptance and cost effectiveness. The sensitivity of the PERMEA-Tec™ sensors is 3-5 µg for aromatic amines and isocyanates.
PERMEA-Tec sensors should be attached to the hands of the worker before gloving. It is recommended that the detector be placed on the thumb, middle finger, and palm, as these areas represent the highest degree of contact and abrasion. During initial evaluation of a new glove, the worker should be double gloved as a safety precaution. Attach PERMEA-Tecâ„¢ sensors to the outside of the glove currently in use and don the new glove over the first. Check sensors hourly to determine when break through occurs and change gloves accordingly.
The picture shows a close-up of two PERMEA-Tecâ„¢ sensors. The top PERMEA-Tecâ„¢ shows the middle strip that has not been exposed to chemical break through. The bottom shows a color change on the middle strip, indicating that break through has occurred.
Studies show that occlusion of skin increases absorption of chemicals by a factor of 5 to10 times. Gloves and non-porous clothing effectively occlude the skin, thereby resulting in enhanced absorption of permeating chemicals. PERMEA-Tecsâ„¢ produce a color change when permeation occurs, thus providing a method for field validation of the efficacy of protective clothing. Use a PERMEA-Tecâ„¢ Glove Sensors once a week (on a daily basis when handling highly toxic chemicals) demonstrates the need for safe work practices and documents protection from chemical exposure.
All PERMEA-TEC sensors require developing solution.
