EN ISO 22078:2011, also known as "Safety of machinery - Safety distances to prevent hazard zones being reached by upper and lower limbs," is an International Organization for Standardization (ISO) standard that provides guidelines for determining safety distances in order to prevent accidents associated with machinery use. This technical article will delve into the details of this important standard and how it contributes to ensuring the safety of workers.
Scope and Purpose
The main objective of EN ISO 22078:2011 is to protect individuals from hazards that may arise during the operation of machinery. It establishes safety requirements and provides guidelines for the determination of safety distances related to machinery design. The standard applies to both new and existing machinery and is relevant to manufacturers, designers, and users alike.
The purpose of this standard is to ensure that hazardous areas of machines cannot be reached by body parts or clothing during normal operation. It considers aspects such as reach distances, arm lengths, and the possibility of access through openings or barriers. By specifying safety distances, this standard helps reduce the risk of accidents and injuries that can occur when working with machinery.
Determining Safety Distances
EN ISO 22078:2011 provides a clear methodology for determining safety distances based on the intended use of the machinery and the possible hazards involved. Various factors come into play, such as the speed of the moving parts, the reaction time of the operator, and the dimensions of the human body parts at risk.
The standard classifies hazards into three categories: stationary hazards, rotating hazards, and hazards associated with robotic systems. Each category has specific measurement criteria and formulas to determine the appropriate safety distances.
It's important to note that safety distances should be defined during the design and manufacturing stages of machinery. Furthermore, regular inspections and assessments should be conducted to ensure continued compliance with this standard.
Benefits and Compliance
Complying with EN ISO 22078:2011 offers numerous benefits for both manufacturers and end-users. For manufacturers, adherence to this standard allows them to produce safer machinery and demonstrate their commitment to ensuring worker safety. Additionally, it can help prevent costly litigation resulting from accidents caused by non-compliant machinery.
End-users, on the other hand, can enjoy a reduced risk of injuries while operating machinery that conforms to the specified safety distances. By following the guidelines outlined in the standard, workplace accidents can be minimized, leading to improved employee well-being and productivity.
In conclusion, EN ISO 22078:2011 plays a crucial role in enhancing machinery safety. With its comprehensive guidelines for determining safety distances, this standard ensures that workers are protected from potential hazards associated with machinery operation. Manufacturers and users alike should actively comply with this standard to create a safer working environment and mitigate the risks posed by machinery-related accidents.
