Corded Headsets and DEHP and DBP
Because of a challenge under California’s Proposition 65, a telecommunications firm asked Cardno ChemRisk to evaluate potential DEHP and DBP exposure in corded headsets typically used in an office or call-center setting. Cardno ChemRisk scientists conducted an evaluation of the hazards posed by the plasticizers in phone cables. A health risk assessment was conducted to assess whether enough DEHP and DBP might be released from the handling of the cable of corded headsets to exceed the Proposition 65 “safe harbor” level. This analysis evaluated dermal absorption via contact with the cord and ingestion via hand-to-mouth exposure. The risks associated with the normal use of the headsets were evaluated, and exposure calculations were presented to counsel representing the Center for Environmental Health.
