With a EN 397 Safety helmet you are relying on the ratchet on the back of the safety helmet to keep the helmet on your head, the ratchet is designed to fit underneath your occipital bone on the back of your head. Typically the ratchet is either a slip ratchet or a wheel ratchet. This fits just underneath to reduce the risk of the safety helmet falling off your head. When a hood is being used the ratchet is not getting a secure fit to the head and the occipital bone and wherefore increasing the risk of the safety helmet falling off your head.

When working at height you should have a suitable safety helmet, one with additional support to keep it on your head such as a 4 point chinstrap.
