Worker Protection vs Ergonomic Freedom
Automate hazardous manual tasks under ISO 45001's hierarchy of controls, using remote monitoring to maintain operational responsiveness without worker exposure.

Regulations
Business Context
Personal protective equipment, barriers, restraints, specialized clothing, gloves, and other protective measures reduce exposure to workplace hazards but can restrict movement, visibility, dexterity, communication, or thermal comfort. When protection makes work significantly more difficult, task duration can increase and new ergonomic risks can emerge.
Automotive TRIZ Resolution
Automotive TRIZ first seeks to reduce the hazard at its source so that personal protection is not carrying the entire safety function. Where protection remains necessary, it can be localized, lightweight, task-specific, or activated only during hazardous phases. Workstation design and automation can further separate employees from hazardous interactions without restricting normal movement.
Applicable TRIZ Principles
Principle 2 – Taking Out removes hazardous exposure from the worker's immediate environment where possible.
Principle 3 – Local Quality concentrates protection on the body regions or task phases that require it.
Principle 15 – Dynamics adapts protective measures according to the actual work condition.
Expected Outcome
Maintained or improved worker protection
Greater ergonomic freedom
Reduced physical strain
Improved task efficiency
Decision Indicators
Early indicators that this contradiction is limiting operations include:
Protective equipment significantly restricts movement or visibility.
Employees remove or modify protection to complete tasks efficiently.
Safety measures create secondary ergonomic problems.
Task duration increases substantially because of protective requirements.
High levels of PPE compensate for hazards that could be reduced at the source.
Monitoring these indicators helps identify when the workplace or process should provide more of the protective function instead of placing the burden primarily on the worker.
