You should always consider the range and scope of hazards when working with machinery. The first stage of the process involves identifying hazards, assessing risks associated with the machinery and ultimately eliminating or controlling those risks by isolating them or using an alternative suitably engineered piece of plant or equipment. Secondly, you should train staff in the safe operation of machines and equipment and provide written procedures in the worker's first language. Thirdly you should develop and implement comprehensive (but understandable) safe operating procedures in consultation with employees and health and safety representatives. Fourthly, ensuring that safety guards and gates are compliant with known standards and fixed to machines at all times. Fifthly it's important to regularly service and inspect machines and equipment. You should also consider placing signs on or near a machine to alert employees of the dangers of operating it and ensure that fall protection such as guards and rails are in place when workers are working from height or near drops.
