Attitudes and opinions about risk are becoming more public and are increasingly being driven by non-experts. This fuels the need for more effective risk communication on your part. Since there are few regulations for risk communication and very few established risk references ("safe" exposure limits exist for only about one percent of all chemicals in commercial use) many environmental health and safety pros struggle with what to do.
EHS pros often lament that the OSHA hazard communication program they used for years "is no longer effective." Often it's not that the hazard communication program is broken or boring, it's that the EHS pro hasn't fixed or updated risk communication to accommodate questions from new employees who may have different values and beliefs from the older workforce.
