What should I do to avoid a rubber accelerator allergy?
The best way to avoid a rubber accelerator allergy is to learn about products that contain rubber accelerators. However, it is generally difficult to determine which products contain rubber accelerators and which do not.
Minimize your exposure to all rubber products. Use alternative products made from vinyl, plastic, wood, leather, or fabric. Although some rubber gloves are labeled 'hypoallergenic', it is wise to contact the manufacturer to determine if they contain any of the rubber accelerators to which you are allergic. Vinyl gloves may be a suitable alternative, although some people are allergic to rubber and vinyl. Tactylon® gloves are a good alternative for most people. Be aware that some rubber gloves provide less protection against viruses and certain chemicals than rubber gloves. Discuss your glove requirements with your supplier / manufacturer.

Avoid shoes made with rubber accelerators. Try on the shoes by wearing them for a few days and watch for a skin rash (shoe dermatitis) or do a patch test on the shoes. Any socks or socks that have been worn with shoes that cause allergies can become contaminated with rubber. They should not be reused, as even washing may not remove the contaminant.
Rubber-free condoms (for example, Durex Avanti) and plastic diaphragms may be suitable contraceptive alternatives. Cover the padded arms of upholstered furniture with a towel and avoid walking barefoot on rubber-coated rugs.
