The following are some highlights of the safety toolbox talks regarding the "QHSE DOCUMENTS-BURIED SERVICES" and their prevention of critical physical injuries or death:
Main Points
- Ensure that all information on existing underground services has been obtained from the main contractor before works commence on site.
- Always assume that there are live services present on site, even if existing drawings /information indicates that none are present.
- Do not assume that buried services are always given their recommended cover, cables may often be just below the surface.
- Treat all services found as live.
- Ensure that all services are physically located and marked utilizing location equipment (for example, a CAT scanner).
- Where practicable, hand-held power tools (i.e., Kango Hammers) should not be used to break the paved surface within 0.5 meters of the indicated line of service.
- Where excavating near the indicated line of service, carefully hand dig trial holes until the line of the service has been established.
- When the excavator bucket is digging, other personnel should keep well clear of the bucket. Should a cable be struck, the driver should stay in the cab, but should he have to leave the cab he should jump down, not climb down otherwise he may be electrocuted.
In case, a gas leak is detected and or electrical strike is suspected the following action should be taken ASAP: -
- Remove all people from the immediate vicinity of a service connection to a building that has been damaged, and warn the occupants and any adjoining building, to leave the building until it is safe to return.
- Inform the related authorities of any gas leak or any cable strike.
- Prohibit smoking and extinguish all naked flames and other sources of ignition, within at least 5m of the leak.
Point to Note:
CHECK BEFORE YOU DIG!!
