Protection against epoxy resins

Occupational skin disease ranks as the most common occupational disease in many countries around the world with 'contact dermatitis' accounting for approximately 90-95 percent of all occupational skin diseases.

Epoxy resins are known to be a major cause of occupational skin disease and put the user at a high risk of contact dermatitis. Most allergic contact dermatitis related to epoxy resin is localised to the hands and forearms.

Contaminated hands can also spread the allergen to previously unexposed sites.

In a 2003 study of occupational dermatitis, epoxy resins were found to be the most important relevant allergen in painter groups, and the second most common relevant allergen in the construction industry.

The three most commonly affected occupations were floor finishers, process workers and spray painters.

Within these applications, it was found that gloves were used by only 67.4 per cent of workers. Furthermore, none of the gloves used gave the wearer adequate protection against epoxy resins.

The characteristics of epoxy resins has led to their extensive use in adhesives, paints, coatings, sealants, fillers, concrete repair, reinforced polymer composites, varnishes, product finishing and laminates.

These materials are widely used in the building and construction, printing, publishing and painting industries. Occupational dermatitis causes widespread injury related costs, including lost time, falls in productivity, employee morale and profitability.

A recent Australian study found that 60 per cent of workers affected by dermatitis had applied for workers compensation and all of them had successful claims. In one study 6.7 per cent of sufferers had at least 12 months off work.

Ansell, in conjunction with an independent German laboratory, conducted glove permeation tests for protection against epoxy resins. The chemical resistance performance was measured on eight chemical gloves against five commonly used epoxy resins.

The results revealed that the Sol-Vex glove showed no signs of permeation after eight hours contact with the epoxy resin, making it an excellent choice for this application. The Sol-Vex glove range is available in a range options that include varying lengths, thicknesses, grip patterns and other variants.

Gloves made out of neoprene, natural rubber or vinyl, were not recommended for protection against epoxies.
