Across industries—from energy installations, manufacturing lines, and logistics hubs to financial control rooms and corporate tech offices—one category of health injury consistently tops the charts for lost workdays, reduced productivity, and long-term disability claims: Musculoskeletal Disorders (MSDs).
Whether it is lower back strain from manual handling, shoulder impingement from overhead reaching, or carpal tunnel syndrome from poor workstation posture, physical stressors place an immense, silent financial drain on businesses.
Yet, despite widespread awareness, many organizations still address ergonomic challenges by simply telling workers to “bend your knees” or buying adjustable chairs that nobody knows how to set up.
True worker protection demands an engineering-backed, human-centered science: Ergonomics.
Gradi Health & Safety Limited is thrilled to open registrations for our final, highly anticipated intermediate cohort of the year: OHTA 506: Ergonomics Essentials, holding live interactive online this December 4th, 5th & 6th and December 12th & 13th, 2026.
Whether you manage shop-floor safety, oversee occupational medical cases, design plant processes, or are advancing your professional portfolio toward the prestigious International Certificate in Occupational Hygiene (ICertOHTA), this course will equip you to anticipate, evaluate, and engineer out ergonomic risks at their source.
Why Ergonomics Matters in Today’s Industry
Ergonomics is not just about physical comfort—it is about fit, function, and sustained human performance. When workplace tasks exceed human anatomical and physiological capacities, the cost manifests in:
- Chronic repetitive strain injuries (RSI) and debilitating back injuries.
- Fatigue-induced errors that trigger catastrophic safety incidents.
- High turnover, absenteeism, and expensive medical compensation.
OHTA 506 bridges the gap between biomechanical theory and practical workplace intervention. You will move past guesswork and learn how to quantify physical risk factors using internationally recognized assessment methodologies.
What You Will Master: Core Learning Pillars
Led by board-certified industrial hygienists with decades of hands-on industrial and field experience, the OHTA 506 curriculum covers:
1. Human Anatomy, Physiology & Biomechanics
Understand how the musculoskeletal system behaves under physical load. Learn the mechanics of muscles, tendons, ligaments, nerves, and spinal discs, and discover exactly how awkward postures, forceful exertions, and repetitive cycles trigger tissue failure.
2. Ergonomic Risk Assessment Toolkits
Gain practical, calculation-level proficiency in world-standard assessment frameworks:
- NIOSH Manual Lifting Equation: Calculating the Recommended Weight Limit (RWL) and Lifting Index (LI).
- Rapid Upper Limb Assessment (RULA) & Rapid Entire Body Assessment (REBA): Quantifying postural stress in dynamic operations.
- Pushing, Pulling & Carrying Assessments: Utilizing Snook Tables and psychophysical criteria.
3. Workstation & Equipment Design Principles
Explore anthropometry—the science of human body dimensions. Learn how to design adjustable, human-centered layouts for both seated and standing workstations, assembly lines, control panels, and Display Screen Equipment (DSE) environments.
4. Physical Environmental Factors Affecting Ergonomics
Investigate how ambient workplace factors interact with human strain, including hand-arm vibration (HAV), whole-body vibration (WBV), thermal extremes (heat/cold), and illumination deficiencies that force workers into awkward compensations.
5. Sustainable Engineering & Administrative Controls
Apply the Hierarchy of Controls to eliminate repetitive strain. Learn how to specify mechanical lift assists, hydraulic scissor tables, vacuum lifters, automated conveyors, and design effective job-rotation and work-rest regimens.
Who Should Attend?
This module is tailored for forward-thinking professionals dedicated to human performance and workplace well-being:
