| No | ACTIVITY | HAZARD | RISK | CONTROL MEASURES TO MINIMISE / ELIMINATE RISK | RESPONSIBLE PERSON |
| 1 | Service location survey | Manual handling operations (MHO’s) | Work related upper limb disorders. Musculoskeletal injuries. Cuts, abrasions. Foot / toe injuries | Maximum use of equipment to reduce need for MHO’s MHO Training prior to any work being carried out, this training is to be documented Wearing of gloves Wearing of safety shoes | |
| | | Extreme heat | Dehydration, heat exhaustion. Heat stroke | Ready supply of cold water and Oral rehydration products ie Salt & Dextrose tablets. No work to be conducted under the sun between 12:00 & 15:00 (July & August only) | |
| 2 | Marking out of excavation | Use of hand tools | Cuts, abrasions, broken bones, eye injuries | Supervisor to inspect hand tools prior to commencement of works to ensure tools are in good condition. Site minimum PPE to be worn at all times | |
| | | Marker paint | COSHH related injuries | Paint to be COSHH assessed prior to use and COSHH assessment finding to be implemented prior to use of any such paint. | |
| 3 | Excavation | People working in excavation | Engulfment, entrapment. Asphyxia, death | Excavation works will be constantly monitored by an authorized and competent person throughout the works. Entry to the excavation will only be allowed after the competent person present has signed an inspection record form stating that the excavation is safe for the entry of operatives. The competent person will inspect the excavation daily prior to any works within the excavation. Effective rescue procedures will be rehearsed at least monthly or more frequently if the churn of staff so dictates. Tool box talk will be given prior to any works being done.( See attached TBT on excavation) All excavations will be conducted under a permit to break ground. Adequate ventilation will be present or arranged. Detection equipment will be present before entry to check on levels of oxygen and presence of toxic or explosive substances. The area will be tested before entry and continually during the presence of persons in the excavation. In a case of the detection equipment sounding an alarm all personal are to leave the excavation. No person is to be more than 25meters from an escape route. | |

| | | Dust | Poor visibility, respiratory Injuries Dust explosion | The area will be wetted prior to the works and thereafter at a frequency sufficient to suppress windblown dust In the event that the dust suppression proves ineffective operatives will be issued suitable RPE. However in the event that dust causes restricted vision, operatives will be removed from the excavation until such time as adequate visibility is restored. | |
| | | Extreme heat | Dehydration, heat exhaustion. Heat stroke | Ready supply of cold water and Oral rehydration products ie Salt & Dextrose tablets. No work to be conducted under the sun between 12:00 & 15:00 (July & August only). In the event that natural airflow is restricted, industrial air movers will be employed. No worker shall work within the excavation for longer than 40 minutes without a ten minute break in a shaded area which will be provided for this purpose. | |
| | | Contact with underground services | Explosion or asphyxia. Loss of airport services | A full and comprehensive services survey will be conducted prior to the works commencing. All (services relevant) information will be obtained from the client prior to works commencing. Work near to known buried services will be conducted by hand. Staff will be briefed on how to recognise the possible buried services that may be encountered. | |
| | | Contaminated land / soil | COSHH Related injuries | Staff will be briefed on the potential contaminants their nature, the hazards and how to recognise them. A process will be implemented that causes operatives who suspect by sight or smell any such contaminants to be present to report any such suspicion to the competent person present. The competent person on being informed of any contaminate will assume the substance to be hazardous and reassign the workers to a place of safety until the suspected substances have been examined by a competent person specialising in Toxic or harmful substances. | |
| | | Equipment falling into excavation | Injuries to operatives in the excavation | A physical barrier will be erected 2 metres from the excavation edge. No vehicles will be allowed closer than 2 metres from the excavation edge. Equipment and stores will not be stockpiled any closer than two metres from the edge of the excavation edge. | |
