Describe the methods used to identify the health and safety hazards that may be present in the working environment with which you are familiar.
Photographic evidence is required to show the hazards identified.
Method 1: walk and imagine. It helps to estimate the risks associated with the field. For example, if I see an easy accessible circuit box, I need to protect it from unauthorized access.
Method 2: measurements. I measure the resistance between the L and PE wires, too high values may lead to improper circuit breakers operation.
