We recently hired a new associate that wears an insulin pump. Part of his job duties entail working in a class 1 division 1 environment. Currently we have kept him from those job duties. The pump, nor any information on the manufacturers website states anything about their pump being intrinsically safe. A submitted request via their contact link has gone unanswered for 3 days. The pump runs on a AAA battery and does have an IPX7 waterproof rating.
What's the best course of action?
