ISO 11228-2:2007/Amd 1:2022 is an important amendment to the international standard focusing on ergonomics and manual handling, specifically addressing the tasks of pushing and pulling. Developed by the International Organization for Standardization (ISO), this document builds upon the original 2007 edition by updating guidelines and recommendations to enhance safety and reduce fatigue during manual pushing and pulling activities. This amendment reflects current ergonomic research and practical applications for workplace safety, emphasizing optimal force application and risk reduction.
Smooth Force Application The amendment highlights the significance of applying smooth, continuous forces while pushing or pulling objects. Jerky movements and prolonged force exertion are discouraged due to their association with increased muscle and whole-body fatigue risks.
Population-Specific Guidelines Relevant ergonomic limits are clarified based on worker demographics. For example, male limits apply when all workers are male, whereas female or mixed groups should follow female limits to ensure safety and inclusivity.
Measurement and Assessment Techniques Practical procedures for measuring initial and sustained forces during cart movement are detailed. These include standardized methods to evaluate peak initial force and consistent sustained force over set distances and velocities, facilitating accurate ergonomic risk assessments.
Risk Reduction Systems The document renames and expands guidance on general risk reduction strategies, reinforcing ways to minimize physical strain during manual pushing and pulling tasks.
Updated Biomechanical Data Amendments include revised compressive force limits on the lumbar spine and adjustments to assessment tables and figures to reflect contemporary biometric understanding, enhancing the standard’s precision and relevance.
ISO 11228-2:2007/Amd 1:2022 serves as a critical resource across multiple sectors where manual handling operations are frequent:
Workplace Ergonomic Design Employers and safety professionals use the standard to design manual handling tasks that minimize injury risk by specifying acceptable force thresholds and recommended worker postures.
Occupational Health and Safety Programs Integrating this standard supports compliance with workplace safety regulations and helps reduce musculoskeletal disorders (MSDs) related to pushing and pulling.
Equipment and Tool Development Manufacturers of carts, trolleys, and other mobile handling equipment can apply these guidelines to optimize design for ease of use, reduce required operational force, and enhance worker safety.
Training and Risk Assessment Occupational trainers and ergonomic assessors utilize the standard’s measurement techniques to evaluate pushing and pulling tasks, enabling data-driven interventions to prevent fatigue and injury.
ISO 11228-2:2007/Amd 1:2022 is part of the broader ISO 11228 series on manual handling, which includes:
Additionally, it aligns with ergonomics and biomechanical standards developed by ISO Technical Committee ISO/TC 159, collaborating closely with related occupational health and safety standards to provide comprehensive guidance on safe manual handling practices.
