Musculoskeletal disorders (MSDs) are among the leading causes of workplace injuries worldwide. Poor workstation design, repetitive tasks, and manual handling can lead to chronic pain, lost productivity, and increased health costs. The OHTA 506 (W506) – Ergonomics Essentials course provides professionals with the knowledge and skills to evaluate and improve workplace ergonomics.

This module, part of the Occupational Hygiene Training Association (OHTA) 500 Series, introduces participants to ergonomics principles and practical strategies to create safer, more efficient working environments.
