That is good and I will recommend him to take this IOSH course. however, he already did a course of IOSH managing safely refresher from a reputable e-learning provider.
My friend took a few general safety courses as a manager but he needs to make sure that he is covering all bases as plenty of time has passed since then. Will an iosh managing safely refresher be viable? Could I get more details on this? Does it cover everything he needs, such as fire safety?
