What is BS EN ISO 61821-2021?

BS EN ISO 61821-2021 is a technical standard that provides guidelines and specifications for the design, installation, operation, maintenance, and testing of mobile elevated work platforms (MEWPs). This standard aims to ensure the safety of workers and the proper functioning of these machines in different operational conditions. In this article, we will explore the key aspects of BS EN ISO 61821-2021 in an easy-to-understand manner.

The Importance of BS EN ISO 61821-2021

The main purpose of BS EN ISO 61821-2021 is to enhance the safety measures associated with the use of MEWPs. These machines are widely used in construction, industrial maintenance, and other sectors where work at height is required. The standard helps in reducing the risk of accidents by providing clear guidelines on various aspects, including stability, structural strength, control systems, and emergency procedures. Compliance with this standard ensures that the equipment meets certain quality and safety requirements, promoting a safer working environment.

Key Requirements of BS EN ISO 61821-2021

BS EN ISO 61821-2021 specifies several important requirements that manufacturers and users of MEWPs must follow. One key requirement is the implementation of adequate safety features to protect workers during operation. These features may include guardrails, harness attachment points, emergency lowering systems, and overload protection mechanisms. The standard also addresses factors such as stability testing, wind forces, and prevention of unintended movements to prevent accidents and maintain the stability of the platform.

Moreover, the standard emphasizes the importance of regular inspections, maintenance, and thorough examination of the MEWPs. Both manufacturers and users have responsibilities to ensure that the equipment is serviced properly and remains in good working condition. This includes scheduled inspections, testing of control systems, monitoring of structural integrity, and adherence to maintenance procedures outlined in the standard. These requirements contribute to extending the lifespan of the machines and reducing the occurrence of breakdowns or malfunctions.


BS EN ISO 61821-2021 is a vital technical standard that focuses on the safe operation of mobile elevated work platforms. By adhering to the guidelines set forth in this standard, manufacturers, operators, and workers can ensure a higher level of safety when using MEWPs. It provides clear instructions regarding design, installation, maintenance, and testing, covering all crucial aspects of these machines. Compliance with this standard not only prevents accidents and injuries but also contributes to the overall efficiency and productivity of the industries where MEWPs are employed.
