Dear Richie, To the specific question: Does the mains within the equipment comprise a hazard? The answer is YES. But the most important aspect is the evaluation of the Risk associated with the hazard. The Risk can be "acceptable" or "unacceptable". Can a harm (electrocutation) be generated due to mains? Which is the probability that this harm occurs? These are the questions to which shall answer. The hazards (potential source of harm) due especially to mains are: electrical shock, fire. The key for analysis is the EXPOSURE to the hazard (with other words the accessibility to the hazardous areas). If not exist EXPOSURE to the hazard or the probability to access the hazardous areas is very small, the associated Risk is acceptable.

We would all agree that mains is a hazardous energy source (or comprises a hazard). The equipment in question is provided with a suitable enclosure and fully complies with the applicable safety standard. We have a number of definitions for "hazard" from the various posted messages: anything potentially harmful potential for an action with adverse outcome something that can hurt you or do property damage potential source of harm Question: Does the mains within the equipment comprise a hazard?
