This part of ISO 10472 covers, together with ISO 10472-1, most significant hazards associated with washing tunnel lines including component machines such as: — continuous tunnel washing machines; — squeeze presses or centrifugal extraction machines; — transfer conveyor systems; — automatic transfer tumblers; — loading or unloading system interfaces; — access platform and ladders. This part of ISO 10472 does not cover particular hazards for continuous stand-alone washing lines for endless towels. This part of ISO 10472 does not cover the hazards caused by processing work which may create an explosive or flammable atmosphere inside the machine. This part of ISO 10472 complements the basic requirements laid down in ISO/TR 12100-1 and ISO/TR 12100-2. It also gives guidance to the designer on assessing the risks associated with the hazards (see EN 1050) and on selecting measures for attaining the required safety level. This part of ISO 10472 does not apply to ancillary equipment, e. g. chemical store and supply pumps, steam valves and supply pipework, vent systems, work feed systems and discharge systems and ducting to the atmosphere.
