“…This may be performed by observation or interviews, as was done in studies of epoxy pipe relining. 24,25 Correspondingly, methods to visualize and quantify contamination by skin-sensitizing metals are available. Examining contamination by hazardous substances is essential to identify and reduce exposure, and prevent disease in the workplace.…”

“…2,3 They are known to be extremely sensitizing to the skin and can sensitize upon first contact. 4 ACD has been reported from various epoxy resin system components, [5][6][7][8][9][10][11][12][13] most commonly from exposure to DGEBA and DGEBF. 14,15 DGEBA is included in the European baseline series for diagnosis of ACD.…”

“…Skin sensitization is also common amongst construction workers (up to 9.7%) and is caused by ERS present in cement and other building materials, 18,23 but is also frequent in newer settings such as the production of wind turbine rotor blades 15 and relining of old pipes. 13 It can also occur in unexpected settings such as microscopy of histological samples, due to the presence of ERS in the microscopy immersion oil. 24,25 Epoxy chemicals are also implicated in non-occupational contact allergy.…”

Epoxy resin monomers, including diglycidyl ethers of bisphenol A and F (DGEBA and DGEBF), are extensively used as building blocks for thermosetting polymers. However, they are known to cause widespread contact allergy. This research describes a number of alternative epoxy resin monomers, designed with the aim of reducing the skin sensitizing potency whilst maintaining the ability to form thermosetting polymers. The compounds were designed, synthesized, assessed for skin sensitizing potency using the in vivo murine local lymph node assay, and tested for technical applicability using thermogravimetric analysis and differential scanning calorimetry. All the novel epoxy resin monomers had decreased skin sensitization potencies compared to DGEBA and DGEBF. With respect to EC3 values, which is the estimated concentration of a substance required to induce a 3-fold increase in sensitization compared to a control, the best of the new monomers had a value approximately 2.5 times higher than those of DGEBA and DGEBF. The diepoxides were reacted with triethylenetetramine and four out of the six novel monomers gave polymers with a thermal stability comparable to that obtained with DGEBA and DGEBF. The new epoxy resin monomers have the potential to replace DGEBA and DGEBF, leading to a decreased incidence of contact allergy due to epoxy resins, decreased healthcare costs, and an increased quality of life for those handling thermosetting materials.

“…Since the 1960s the use of resins and glues in the trade has increased, while the use of lead, for example, has decreased. The pipe re-lining methods introduced in the 1970s implied exposure to uncured plastic components, which adds to the risk of contact allergy (24,25).…”

Disability pensions due to skin diseases in Swedish male construction workers were studied by linking data from pension registers and an occupational health service. Incidence rates of disability pensions for cement workers, painters and plumbers were compared with 2 control groups. A total of 623 disability pensions were granted during 4 decades of follow-up. The main diagnoses were eczema (36%) and psoriasis (49%). Pensions were mostly granted in the age range 55-64 years. Among painters, cement workers and plumbers the incidence rates for disability pensions were 33.3, 24.5 and 20.4 cases/100,000 person-years, respectively, compared with 13.7 and 9.2 cases/100,000 person-years in control groups. Relative risks were highest for eczema, and were notable for psoriasis. Attributable fractions for eczema were 90% in cement workers and painters and 75% in plumbers compared with control groups. Attributable fractions for psoriasis in the occupational groups studied were in the range 54-67%. In conclusion, eczema and psoriasis have a high impact on loss of work ability, as reflected by disability pensions.
