Indicator shows time to replace helmets
A small disk, the size of a ten pence piece, which changes colour whenit is time to change a safety helmet, has just won an award.
The Peltor "Uvicator", is a small red disk of treated plastic that when incorporated in a newsafety helmet, is initially red all over, but bleaches in sectors underthe effects of ultra violet light. When it is white all over, it istime to replace the helmet.
Aearo told us that safety helmets, especially those used in sunnyclimates, are often still being used when their plastic hasdeteriorated to the point that they provide little real protection.
