This part of EN 746 specifies common safety requirements for industrial thermoprocessing equipment (for example industrial furnaces and industrial heating equipment), which meets the definition for machinery given in EN ISO 12100-1:2003. It details the anticipated significant hazards associated with industrial thermoprocessing equipment and specifies the appropriate preventative measures for reduction or elimination of these hazards. This standard gives general principles and common requirements for the reduction of risks for equipments covered by the scope. The common requirements apply to all of the subsequent parts of this EN 746 dealing with specific equipment unless an exception is stated in the relevant Part. The general principles (subclauses are pointed out) will be used to establish the specific technical measures in the subsequent Part(s) dealing with safety requirements for particular equipment. NOTE For similar equipment not covered by the particular Parts of this standard, EN 746-1 can be used to assist in the reduction of risk for the Hazards identified in clause 4 (List of Hazards). This part of EN 746 is applicable to industrial thermoprocessing equipments for use in fields such as: Metallurgical and metal working plant; Glass making plant; Ceramic manufacturing plant; Cement, lime and gypsum manufacturing plant; Chemical plant; Waste incineration equipment; And heated by: Gaseous fuels; Liquid fuels; Solid fuels; Mixed fuels; Electricity. The thermoprocessing equipment covered by this Part of EN 746 is further specified in clause 3. A more detailed list of thermoprocessing equipment within these categories is given in Annex A. In the remainder of this standard the expression "equipment" will be used. This Part of EN 746 is not applicable to blast furnaces, converters (in steel plants), boilers, welding machines or food processing equipment. This Part of EN 746 specifies the requirements to be met by the manufacturer to ensure the safety of persons and property during commissioning, start-up, operation, shut-down, maintenance periods and dismantling, as well as in the event of foreseeable faults or malfunctions which can occur in the equipment. It specifies the safety requirements at stages in the life of the equipment, and its design, ordering, construction, use and disposal. It specifies safety requirements for: Protection against: Mechanical hazards, movement of machinery and material, ejection of parts or material or liquids and gases, implosion, structural failure; Electrical hazards; Thermal hazards: explosion, fire, scalds, contact with hot parts, gases and flames; Noise and vibration; Thermal, optical and ionising and non-ionising radiation; Harmful by-products and hazardous substances, poisoning, biological and microbiological contamination, pollution and environmental discomfort; Other hazards such as listed in clause 4; maintenance, provision for indicators, and inspection. This part of EN 746 applies to equipment which is placed on the market after the date of issue of this standard.
