Risk Assessment Matrix
| SN | Activity | Hazard | Consequence | Groups Exposed | Controls | Initial Risk | Additional Controls | Residual Risk |
|---|---|---|---|---|---|---|---|---|
| 1 | Site Mobilization, Equipment Transport, and Access Setup | 1. Vehicle movement and collision during transit/site access 2. Slips, trips, and falls on uneven ground or terrain 3. Manual handling injuries during offloading of testing equipment | Fractures, lacerations, vehicle damage, bodily trauma, muscle strain | Site operatives, drivers, visitors, site engineers | 1. Enforce site speed limit of 20 km/h and designated access routes 2. Mandate banksman/flagman for all reversing vehicles 3. Conduct site safety induction and toolbox talk prior to entry 4. Wear mandatory PPE (safety helmet, high-vis vest, safety boots, gloves) 5.sdasdasd asdsd dssad asds 6. adsdsad asdsad dads |
