Eliminate hazard

After MSD hazard is identified, the best solution is to eliminate it.

• Effective and no further action is required

• May not be possible

• Powered roller conveyor instead of carrying boxes

Substitute hazard

The hazard can be substituted with another approach that creates smaller MSD risks

• Can be almost as effective as elimination

• Substitution may still have risks of MSD

• Ceiling lift for patients in hospital instead of manual transfer BUT high loading on shoulders to push lift with the patient in it.

Engineering controls

Design of the physical workplace to reduce MSD hazards by machinery, tools or equipment

• Effective long-term controls
• Used by all workers
• If installed and maintained, sustainable control of exposure to hazards

• May appear expensive compared to administrative controls

• Changing tools or modifying power or hand tools>
• Removing obstructions or adding adjustability

Administrative controls

Changes to work organization such as

• work hours
• breaks
• job rotation

• A wide range of controls is available
• May not require physical changes to the workplace

• Resources required for adherence
• Training and retraining

• Break scheduling shown to be effective for MSD prevention

Training and awareness

Designed to change a workers’ knowledge or behaviour such as

• hazard awareness training
• training in work methods

• Hazard awareness and knowledge are required under some legislation

• Ongoing costs associated with training
• Ongoing costs of providing PPE
• Resources required for monitoring  adherence

• "Lift Training” or “Job rotation” not shown to be effective for MSD prevention
• Training in the USE of a specific control is critical for their effectiveness in MSD prevention (and safety)

Barriers between the individual and the hazard that are worn by a worker

• Considered cheap
• Requires little change to the workplace or work organization

• Ongoing costs for new PPE
• Resources required for adherence to wearing PPE
• Many types of PPE not even shown to be effective for MSD even under good conditions

• Only some anti-vibration gloves and knee pads shown to be effective
• Back belts” not shown to be effective as a general workplace control
