mechanical, electrical, thermal, noise, radiation, vibration, dust and materials hazards (e.g. from the aerosols of addi- tives). The aim of this standard is to protect personnel from many of the hazards associated with feed mills by addressing safety requirements for the design and manufacture of feed production machinery.
3. Control of cross-contamination in feed producing lines – guidelines (proposed by Iran) Different kinds of feed for various species and stages of life, as well as medicated and non-medicated feeds are usually manu- factured on the same production line in feed mills. Some materi- als, such as veterinary drugs, feed additives and some feed in- gredients (animal by-products, non-protein nitrogen sources, etc.), which may be hazardous to certain species, are used in the same plant. This standard will describe the technological and operational suggestions for controlling the unintended intro- duction of hazardous materials into subsequent batches of feed.
A common language for the industry Compound feed machinery and equipment are manufac- tured by companies around the world. As a result, there are
many countries involved in the export and import of feed machinery. Each country has its own standards and criteria, but this industry needs to have uniform international stand- ards to set minimum personnel safety and hygiene require- ments, while protecting proprietary information and designs. International standards serve as a common language for the industry and for trade. ISO is the organisation that develops and publishes interna- tional standards and ISO/TC 293 is responsible for developing harmonised standards for feed machinery. Some manufac- turers have concerns that international standards will limit their creativity and innovation and they are encouraged to get involved by offering expert opinions on behalf of their country’s industry to ensure that such constraints are minimised.
In conclusion, it is expected that international standards in the areas of terminology, safety and the hygiene of feed ma- chinery will be completed by ISO/TC 293 over the next three years, setting benchmarks for feed machinery production globally. The greater the international participation, the stronger the standards will be.
