Operating machines safely is clearly vital. Hazards related to paper machines include excessive efforts, inadequate area lighting, hazards resulting from harmful gases and from anoxia, explosion, hearing loss (deafness), other physiological disorders. Therefore, there is a need for safety requirements while manufacturing and installing machines.
BS EN 1034 series specifies safety requirements for the design and construction of paper making and finishing machines. BS EN 1034-7 focuses on safety requirements for chests used in paper making.
BS EN 1034-7 applies to chests used in paper making. BS EN 1034-7 deals with all significant hazards, hazardous situations and hazard events relevant to chests when they are used as intended and under the conditions foreseen by the manufacturers.
Note 1: BS EN 1034-7 does not apply to chests manufactured before the publication date of this European Standard.
Note 2: BS EN 1034-7 does not apply to tanks for chemicals, storage tanks for starch and other additives used in paper making or basins or vessels for waste water resulting from the paper making process.
BS EN 1034-7 on paper machine chests safety is useful for:
Safeguards are essential to protect workers from injury. Pulp and paper manufacturing can also be very hazardous due to massive weights and falling, rolling, and sliding pulpwood loads. Workers can be crushed by loads or suffer from the misuse of equipment, particularly when machines are used improperly. BS EN 1034-7 provides you with all necessary safety requirements and measures for machinery. You need to comply with the safety requirements and measures for safe use of paper machines.
Chests shall be provided with a ventilation opening preventing a vacuum or excess pressure being generated during filling or draining. BS EN 1034-7 also guides you with equipment and measures for maintenance and cleaning the chests in machines.
There is a risk of explosive atmospheres being generated inside the chest during the process, for example, caused by sewage gases or hydrogen. BS EN 1034-7 provides you guidance on explosion protection.
When carrying out the risk assessment, the machine designer must check whether the list of hazards in BS EN 1034-7 is complete and applicable with respect to his machine. BS EN 1034-7 guidelines help you to ensure safety and protection from hazardous situations when operating chests used in paper making and finishing machines.
