Not if the equipment design provided single-fault tolerance against exposing the hazard to the operator or the environment where it's used. (i.e. not a fire or a shock hazard unless two things go wrong with the protection)
For example, cord connected equipment needs both loss of ground connection and failure of basic insulation from the mains circuit to accessible, conductive parts. Now the hazard comes into existence. _______________________________________ _____________________________________________ Ralph McDiarmid | Schneider Electric | Renewable Energies Business | CANADA | Regulatory Engineer From: Richard Nute <[email protected]> To: [email protected] List-Post: [email protected] Date: 11/01/2010 04:59 PM Subject: [PSES] Application of the definitions of the word "hazard" ________________________________ With regard to the use of the word "hazard," consider an equipment supplied from mains. 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?
