tinue to work in an area with potential beryllium exposure should be closely monitored to detect CBD.
CBD. Workers with CBD should discontinue work in areas that have beryllium exposure because of concern about worsening the disease. Although the effect of continuing exposure to beryllium at relatively low concentrations has not been clearly shown, the potential for CBD to become serious suggests that, given the current state of knowledge, it is prudent to avoid further beryllium exposure. Workers with CBD should continue to receive regular medical followup. Workers with CBD who discontinue work with beryllium should receive medical removal protection. If workers understand the risk and elect to continue exposure, their exposure should be kept as low as feasible, and they should have regular medical followup and regular advice about the risk of disease progression.
