The responsible person is to ensure all the controls below are in place before the activity takes place
| TASK: Construction of AGL Ducts & installation of precast AGL Lighting Pits | Date: 04 November 2006 | |||||
| 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 | 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. | ||
| 3 | Installation | Manual Handling | Work related upper limb disorders. Musculoskeletal injuries. Cuts, abrasions | 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 | ||
| People falling into excavation | Engulfment, entrapment. Asphyxia, death | The excavation will be protected on all sides by a fixed barrier which will be highly visible and will be illuminated in the hours of darkness. Warning boards will be erected on all sides of the excavation. Effective rescue procedures will be rehearsed at least monthly or more frequently if the churn of staff so dictates. | ||||
| Contact with cementatious / Bituminous products | Dermatitis, alkali burns | COSHH assessments are to be available for substances likely to be found, used or produced during work. | ||||
| Dust | Poor visibility, respiratory Injuries Dust explosion | An effective Dust suppression programme will be in place prior to the works commencing, and thereafter as necessary to suppress the dust sufficiently. In the event that the dust suppression programme fails operatives will be issued suitable RPE. In the event the dust causes restricted vision, operatives will be removed from the excavation. | ||||
| Vibratory tools | Vibration induced injuries | All vibrating equipment will be serviced in line with the manufacturer’s guidance. Operatives will be rotated to minimise exposure. | ||||
To be read in conjunction with the relevant AHA
| High pressure airlines | Eye injuries, injection injuries | Hose connections will be checked regularly for security and damage. Strict supervision will ensure that there is no horseplay with compressed air. The safe working pressure will be identified on all air receivers and will not be exceeded. | |||
| Material falling from excavator shovel. Shovel of excavator or load dropping inadvertently | Injuries to persons in area | No person will work within the traversing arc of an excavator | |||
| 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. | |||
| Collapse of 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. At least two access & egress points will be maintained throughout the works. Effective rescue procedures will be rehearsed at least monthly or more frequently if the churn of staff so dictates. | |||
| 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. This briefing will be documented. | |||
| Contaminated land / soil | COSHH Related injuries | Staff will be briefed on the potential contaminants their nature, the hazards and how to recognise them. A procedure 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 | Physical barriers 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. |
| Blood born pathogens (BBPs’) | BBP Related injuries | Staff will be briefed on the potential contaminants their nature, the hazards and how to recognise them. A procedure 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. | |||
| Vehicles falling into excavation | Plant related injuries. | An exclusion zone will be erected No vehicles will be allowed closer than 2 metres from the excavation edge. | |||
| Noise | Deafness, CEMP violation | Noise monitoring will be conducted to measure noise as required by the CEMP. Proactive measures will be taken to reduce noise SFAIRP. Hearing protection will be available on request to all exposed staff should the TWA Noise level reach 80dB. Hearing protection will be mandatory if the TWA background noise reaches 85dB. Toolbox talk to be delivered on Noise. (attached) | |||
| Unplanned vehicle movements | Plant on plant incidents. Pedestrian injuries | A strict Plant / Vehicle and operative / pedestrian separation regime will be enforced. | |||
| Venomous insects. | Potentially lethal bites | Areas to be excavated will be beaten ala “Turkey Shoot” as necessary prior to any works being undertaken. Operatives will be shown what constitutes a potentially lethal insect. | |||
| Venomous Snakes | Potentially lethal bites | Areas to be excavated will be beaten ala “Turkey Shoot” as necessary prior to any works being undertaken. Operatives will be shown what constitutes a potentially lethal insect. |
