BS EN ISO 12100:2019 is an international standard that provides guidelines for the safety of machinery and machinery systems. It specifies general principles for risk assessment and risk reduction to help ensure the safety of both operators and others who interact with machines. This standard covers various aspects, including design, construction, installation, maintenance, and operation of machinery.
Understanding Safety Risks in Machinery
Machinery can pose serious risks, ranging from mechanical hazards (e.g., moving parts, sharp edges) to electrical hazards (e.g., faulty wiring, electric shock). Inadequate safety measures can result in accidents, injuries, or even fatalities. BS EN ISO 12100:2019 emphasizes the importance of identifying and evaluating potential risks associated with machinery throughout its lifecycle.
To assess these risks effectively, the standard outlines a systematic approach that takes into account both the machine's intended use and any foreseeable misuse. Factors such as the machine's ability to withstand external influences, ergonomic considerations, and the reliability of safety-related control systems are also considered during risk assessment.
Risk Reduction Strategies
Once the potential risks have been identified, BS EN ISO 12100:2019 provides guidance on implementing appropriate risk reduction measures. The standard promotes a hierarchy of control measures to minimize risks:
Elimination: The highest level of risk reduction involves completely removing the hazard or hazardous process from the machinery. For example, replacing a manual task with an automated one.
Substitution: If complete elimination is not possible, substituting a hazardous component or material with a less dangerous alternative may be considered.
Engineering Controls: This level involves designing and implementing safety measures, such as physical guards, interlocks, or emergency stop mechanisms, to reduce the risk of accidents.
Administrative Controls: These controls include implementing warning signs, safety instructions, and training programs to inform and educate individuals on the risks associated with machinery use.
Personal Protective Equipment (PPE): When all other measures are insufficient, PPE, such as safety goggles, gloves, or helmets, can be used to provide a final line of defense against potential hazards.
Adherence to BS EN ISO 12100:2019
Manufacturers and machine designers should adhere to BS EN ISO 12100:2019 when developing machinery or modifying existing machines to ensure compliance with safety standards. By following this standard, organizations can demonstrate their commitment to providing safe working conditions and protecting the well-being of workers.
BS EN ISO 12100:2019 serves as a valuable resource for engineers, manufacturers, and other professionals involved in machine design, enabling them to enhance user safety, improve productivity, and meet regulatory requirements.
