Ergonomic Risk Assessment for Electrical Workers During Data Center Construction

Assessment Date: [DATE]

Assessor: [ASSESSOR NAME]

Department/Area: [DEPARTMENT/AREA]

Review Date: [REVIEW DATE]

1. Assessment Scope

This risk assessment focuses on identifying and mitigating the risk of soft tissue injuries and musculoskeletal disorders (MSDs) among electrical workers during data center construction. It includes tasks related to electrical installation, cable pulling, equipment handling, and repetitive movements. The scope excludes injuries resulting from trips, slips, falls, electric shock, or other non-ergonomic hazards.

2. Risk Assessment Methodology

This risk assessment employs a 5x5 risk matrix to evaluate the likelihood and severity of potential injuries. The hierarchy of controls (Elimination, Substitution, Engineering Controls, Administrative Controls, and PPE) will be used to determine appropriate risk mitigation strategies.

3. Risk Matrix Reference

The following matrix is used to evaluate risk levels based on likelihood and severity:

		Likelihood
Rare	Unlikely	Possible	Likely	Almost Certain
Severity	Catastrophic	Low	Low	Medium	Medium	High
Major	Low	Low	Medium	Medium	High
Moderate	Low	Medium	Medium	High	Extreme
Minor	Low	Medium	High	Extreme	Extreme
Negligible	Low	Medium	High	Extreme	Extreme

4. Hazard Identification and Risk Evaluation

1. Manual lifting and handling of heavy electrical equipment (transformers, panels, cables).

Potential Consequences: Back injuries, muscle strains, hernias.

Affected Persons: Electrical workers

Initial Risk Assessment

Likelihood	Severity	Risk Rating
Likely	Major	High

Control Measures

• Use mechanical aids (e.g., cable pullers, lifts) to reduce manual lifting and pulling forces.
• Implement team lifting techniques for heavy objects.
• Provide training on proper lifting techniques.

Residual Risk Assessment

Likelihood	Severity	Risk Rating
Possible	Moderate	Medium

2. Prolonged standing or awkward postures during cable installation and termination.

Potential Consequences: Lower back pain, leg fatigue, musculoskeletal disorders.

Affected Persons: Electrical workers

Initial Risk Assessment

Likelihood	Severity	Risk Rating
Possible	Moderate	Medium

Control Measures

• Use adjustable workstations and tools to accommodate different worker sizes.
• Provide anti-fatigue mats for standing work.
• Implement job rotation to vary tasks and movements.

Residual Risk Assessment

Likelihood	Severity	Risk Rating
Unlikely	Minor	Low

3. Repetitive hand and wrist movements during wire stripping, crimping, and screw driving.

Potential Consequences: Carpal tunnel syndrome, tendinitis, hand-arm vibration syndrome (HAVS).

Affected Persons: Electrical workers

Initial Risk Assessment

Likelihood	Severity	Risk Rating
Likely	Moderate	High

Control Measures

• Use ergonomic tools with comfortable grips and reduced vibration.
• Provide regular tool maintenance to ensure proper functioning.
• Implement tool balancing systems to reduce weight and strain.

Residual Risk Assessment

Likelihood	Severity	Risk Rating
Possible	Minor	Medium

4. Poor lighting and visual strain during detailed electrical work.

Potential Consequences: Eye strain, headaches, blurred vision.

Affected Persons: Electrical workers

Initial Risk Assessment

Likelihood	Severity	Risk Rating
Possible	Minor	Medium

Control Measures

• Provide adjustable lighting to reduce glare and shadows.
• Use magnifying tools to improve visibility of small components.
• Implement regular eye exams to detect and correct vision problems.

Residual Risk Assessment

Likelihood	Severity	Risk Rating
Unlikely	Negligible	Low

5. Sustained awkward neck and shoulder postures while working in confined spaces or overhead.

Potential Consequences: Neck pain, shoulder impingement, thoracic outlet syndrome.

Affected Persons: Electrical workers

Initial Risk Assessment

Likelihood	Severity	Risk Rating
Possible	Moderate	Medium

Control Measures

• Provide training on proper body mechanics and posture.
• Use adjustable chairs and footrests to support proper posture.
• Implement workstation assessments to identify and correct ergonomic deficiencies.

Residual Risk Assessment

Likelihood	Severity	Risk Rating
Unlikely	Minor	Low

5. General Control Measures

• Implement a comprehensive ergonomics program that includes hazard identification, risk assessment, control implementation, and training.
• Encourage early reporting of pain, discomfort, or other symptoms of MSDs.
• Provide regular breaks and job rotation to reduce prolonged static postures and repetitive movements.

6. Emergency Preparedness

• Emergency response plan includes procedures for reporting injuries, providing first aid, and evacuating the work area if necessary.

7. Training Requirements

• Safe Lifting Techniques: Training on proper lifting techniques, including how to assess load weight, maintain proper posture, and use lifting aids.
• Ergonomic Workstation Setup: Training on the proper use and adjustment of workstations, chairs, and tools to minimize strain and promote good posture.
• Early Reporting of MSD Symptoms: Training on the importance of early reporting of pain and discomfort, and the procedures for reporting injuries.

8. Monitoring and Review

Review Frequency: Annually, or after any significant change in work processes or reported incidents.

Monitoring Type	Frequency	Responsible Party	Description
Regular Inspection	Monthly	Safety Manager	Regularly inspect workstations and work practices to identify ergonomic hazards.
Performance Indicator	Quarterly	Safety Committee	Review injury and illness records to identify trends and areas for improvement.
Audit	Annually	Human Resources	Conduct employee surveys to gather feedback on ergonomic concerns and the effectiveness of control measures.

9. Special Circumstances

• Working in hot or cold environments can affect muscle flexibility and increase the risk of injury.
• Night work can disrupt sleep patterns and increase fatigue, leading to poor posture and increased risk of MSDs.
• Lone work may delay injury reporting and access to first aid.
