Zone 1 - water heaters, showers and shower pumps and SELV fixed equipment may be installed in zone 1. The electrical equipment must have at least IPX4 protection against water splashing from any direction. If the electrical equipment may be exposed to water jets from, for example, commercial cleaning equipment, then the electrical equipment must have IPX5 protection. (The Index of Protection codes were discussed earlier, and are shown in Fig. 3.74.)... 

Where the strict quantitative analysis of risk by probabilistic methods is difficult or impossible, andysts appreciate fast heuristics. Such methods are fire risk indexing, point schemes, scoring methods (HaU Watts 2008, Watts 2002). However, it should be noted that these methods are only practical when carrying out a fast analysis at the level of fire protection equipment, as well as to determine the necessity of additional fire prevention measures. 

To assess the potential hazard of a new plant, the index can be calculated after the Piping and Instrumentation and equipment layout diagrams have been prepared. In earlier versions of the guide the index was then used to determine what preventative and protection measures were needed, see Dow (1973). In the current version the preventative and protection measures, that have been incorporated in the plant design to reduce the hazard-are taken into account when assessing the potential loss in the form of loss control credit factors.
