NEBOSH NC1 Appropriate General Site Control Measures Flashcards
As well as good site planning, what other considerations should given?
Preparation for specialist activities.
- Site security and protection of the public.
- Arrangements with clients and occupiers of premises.
- Arrangements for site inductions.
- Rules for working in occupied premises
Site Planning - This not only requires the protection of the construction workers, but also members of the public and vulnerable groups, such as children. Ensuring these controls are adequate relies on good planning and management. Outline planning arrangements for site access?
- Suitable signs should be placed at site entrances and elsewhere, warning of the site activities.
- Site traffic will need good visibility entering and leaving the site.
- Site offices and staff parking should be close to the entrance.
- Access should be controlled and visitors signed in and out.
- Arrangements for waste collection and removal should be in place.
- Access for emergency services should be identified and kept clear.
- Consideration should be given to any footpaths or public rights of way through the site.
Re roadways outline the site planning arrangements?
- All roadways and pedestrian routes should be properly signed.
- Pedestrians should be segregated from vehicles as much as possible.
- A one-way system should be put in place, with designated reversing areas if this can’t be avoided.
- Liaison with local authorities may be needed for controls on public roads.
Re loading and unloading outline the site planning arrangements?
- Safe areas for this will be needed, away from pedestrian activity.
- A banksman should be used for reversing and unloading operations.
- Operations may need to be halted while certain crane or unloading activities take place.
Re offices outline the site planning arrangements?
- Site offices should be as close to the site entrance as possible.
- They are usually portable buildings and local authorities may need to be notified of their presence.
- Some buildings may be more than one floor high and adequate fire precautions and escape arrangements must be in place.
- All temporary services to site offices are to be correctly identified and protected from damage where necessary.
Re lighting outline the site planning arrangements?
- All site access routes, signs, scaffolding and waste skips should be well lit and free from dark, shadowy areas.
- There should be enough lighting to allow people to move around the site safely.
- Some areas, such as pedestrian crossings, may need local lighting.
Re signs outline the planning arrangements?
- The health and safety plan will show where on the site layout it is best to place signs, which are likely to be moved as work progresses.
- All signs must be clear and conform to European standards.
- Traffic signs should be reflective, or may require lighting.
Site preparations for specialist activities - Describe considerations for lifting operations?
Using cranes will require good access, firm ground, plenty of room and a safety zone to exclude pedestrians. Overhead safety must also be ensured, to avoid obstructions such as cables.
Site preparations for specialist activities - Describe considerations for Piling operations?
This also requires good access and space for the mechanical pile-drivers. Noise and dust can be issues here. Safety zones should be applied and all buried services should be identified before any work starts. Cranes may be used together with pile drivers to lift and locate pilings.
Site preparations for specialist activities - Describe considerations for stealwork ?
Safe areas will be required to bring in and store materials. Cranes may be used to lift the steelwork, so exclusion zones will apply. Safe Systems of Work (SSW) for work at height must be in place.
The purpose of site security is to protect both the assets (plant, equipment, chemicals, etc.) on site, and members of the public on and off site, who may not be familiar with construction activities. Outline what site security should consist of ?
- Perimeter fencing.
- Security guards on the premises.
- Locked gate.
- Means of securing plant and chemicals.
- CCTV and electronic intruder alarms.
- Roadside and security lighting.
- Safe viewing points.
- Management and procedural measures, such as:
- Visitor registration and sign-in procedures.
- Escorting persons while on site.
- Education, especially of children.
All construction sites use security fencing (‘heras’ fencing) or hoarding (usually wooden boards) and apply safety signs to warn of the dangers on site.
Outline what site fencing should consist of?
- security guard at a gate to permit only authorised persons to enter.
- Be at least two metres high and must be well maintained.
- Not be easy to climb.
- Be robust and able to withstand bad weather and extreme environmental conditions.
Outline site precautions and measures to protect the public?
- Pedestrian tunnels and walkways with lighting.
- False ceilings and crash-decks.
- Sheeting on scaffolding.
- Wrapping protrusions (bolts, couplings, etc.).
- Barriers and signs around excavations.
- Safe viewing points in safe areas and vision panels in solid hoardings.
- Precautions for special risk groups, such as disabled persons, should be considered.
Outline site precautions that reduce risk involving children?
- Removing all ladders from scaffolding,buildings,work platforms,etc and storing them in a secure area.
- Providing secure and adequate supports around all excavations.
- Immobilising plant, such as dumpers, excavators and other site vehicles.
- Isolating all electrical equipment not required for night safety and security and ensuring the integrity of emergency electricity supplies to the site.
- Reducing the height of all stacked materials.
- Covering any holes that cannot be filled in.
- Blocking off debris chutes by fitting lids or covers to prevent them being used as slides.
- Locking away all chemicals, gas cylinders, tools and equipment in safe and secure storage facilities.
- Providing secure storage tanks for petrol, diesel, oil. etc
List some examples of asbestos use?
- Insulation board - contains around 20-45% asbestos - used for fire protection; heat and sound insulation; in ducts; in-fill panels; ceiling tiles; wall linings; bath panels and partitions; and fire doors.
- Pipe lagging - contains 55-100% asbestos - used for thermal insulation on boilers and pipes.
- Fire blankets - used in homes and commercial catering kitchens.
- Floor tiles - very similar in appearance to ordinary vinyl or plastic tiles.
- Sprayed coatings/loose fill - inside roofs, lofts, etc.
- Rope and gaskets - used as seals around jointed pipe and in joints in boilers.
- Roof felt - rolls of felt laid on roofs; roof tiles.
- Decorative paints and plasters - lining walls, around and beneath staircases, etc.; ‘artex’ ceiling coatings.
Asbestos cement products include:
- Corrugated roof sheets.
- Rainwater goods (fountain heads, guttering, drain pipes, etc.).
- Cold water tanks and toilet cisterns.
