Occupational health design review reports at defined design stages
Noise, vibration, and hazardous substance risk assessment inputs
Ergonomic and human factors assessment reports
Design risk register entries addressing occupational health hazards
Written recommendations for risk elimination or reduction at design stage
Contribution to safety-in-design and health-in-design documentation
Final summary report demonstrating how client focus areas have been addressed
Onsite assurance of OH hygiene provision – and clinical assessment
Implement personal and onsite exposure monitoring regime and audit plan
