    Soft ground should be well rammed and leveled. Fixing like steel bolts, nails of fiber rope of approved size, joint pins and couplers should be properly fitted. For load-bearing right-angled or swivel, couplers must be used. Putlog couplers are useful for putlog members only. Putlog members horizontal, ledger must be at least cm be inserted in the wall. Bracing diagonal connection must be tied to ensure structural stability and prevent buckling.

    They are portable and most useful for maintenance. To prevent overturning, height should not be more than three times the minimum width of the base. The minimum base length should be 4 feet. Tools and materials should be removed before moving. The rigidity of the tower is secured by diagonal bracing on all four sides and on the plan. Moving the tower scaffolding by pulling at the top or leaning sideways should be avoided.

    Rolling or mobile tower scaffold is shown below. Outrigger Scaffolding It is a balcony type cantilever scaffold resting on the wall. If other types of the scaffold are possible, this type should not be used. The outriggers should be passed right through the wall and be secured on the inner side. Supporting hook between brick joints is dangerous. Guard rail and toe board should be provided.

    Swinging Hanging Scaffolding Here the platform is hanging by two chain pully blokes, ropes and hooks on supporting beam. The suspended platform can be raised or lowered as per need. The movement of both ends should be simultaneous. The anchorage and the suspension gear should be strong enough to withstand the load with good factors of safety. Suspension ropes should withstand 6 times safety factor 6 the intended load. Rope diameter shall be more than 0. A safety rope shall be provided in addition to the suspension ropes.

    The width of the platform must have more than 50 cm and less than 90 cm. The platform must be lashed or secured while in use to prevent swaying. Each person working on a swinging scaffold should wear Full body safety harness with a lifeline attached to an anchorage other than the scaffold itself. Lifeline must be able to carry a minimum weight of kg. Suspended Scaffolds Two or more platforms are suspended by ropes from overhead outriggers anchored to the building.

    Such scaffolds are designed with a factor of safety 4 and shall never be overloaded. Anchor plates should be tied with U bolts. Counterweights are used to prevent overturning. Wire ropes FS 6 are used to support scaffold. The gap between the handrail and toe board should be covered by a wire mesh of 38 mm and 16 gauge wire. Overhead protection should be provided if the risk of falling objects is possible.

    Cleats extending in front to at least 23 cm should be securely fixed under the chair at both ends. The chair is supported by a suitable sling passing through the four corner holes in the chair for proper stability.

    The suspension rope is fixed to overhead support or passed through a pully block fastened to such support.

    11 Scaffolding Safety Tips To Be Aware Of

    These accidents are often preventable, making a bit of preparation incredibly valuable. Continue reading for a list of scaffolding hazards and tips to prevent them. Additionally, employees themselves have a responsibility for their own safety. The following are several tips employers and employees can follow to prevent scaffolding hazards and accidents while on the job site.

    Use proper safety equipment First of all, personal protective equipment PPE is a must when working in any industrial or construction setting, especially at height. Many of the injuries that occur on scaffolds involve falling objects, so wearing a hard hat can go a long way toward preventing serious injury.

    Non-slip footgear and fall arrest equipment are also important when working on platforms. Mind load limits Scaffolding materials and designs are made with specific load-bearing capabilities in mind. Platforms may crack, break, or otherwise collapse entirely, causing serious injuries for anyone working in the vicinity.

    Know all relevant regulations and standards Each industry has its own regulations and standards to follow, and those regulations may vary from state to state or even city to city. Inspect scaffolding materials Before setting up your work platforms, you must inspect all of your materials before construction. Make sure none of the parts you use have any defects or damage that could compromise the structural integrity of your scaffolds.

    Also, all parts should be sourced from the same manufacturer and designed to be used together. Mismatching parts can pose a major scaffolding hazard and lead to a structural failure.

    Build properly Follow any instructions provided by the manufacturer when building your scaffold. In particular, check that you are using the right types of bracings and fasteners.

    Jury-rigging these components is not an option since it could compromise the entire structure. When building your scaffold, you also want to ensure the area is completely safe. A level ground surface works best if possible , and you should try to avoid intersecting with power lines on your way up. The area should be checked over regularly for hazards, defects, debris, or other factors that could cause a problem.

    Setting up barriers to prevent collisions with the base can keep the whole structure from toppling. In some cases, it may be necessary to have heavy equipment nearby. In those situations, make sure the equipment has enough clearance. Stay organized Tools and equipment should be kept organized and put away after use. At the end of each day, check that there are no tools or materials left on the platform—clutter could lead to trip and fall injuries, or they may pose a hazard for those working on lower levels.

    Mind the weather When working at height, you want to make sure the working conditions are safe. Working during harsh weather conditions or when other environmental hazards are present can increase the risk of serious injury. For instance, high winds could pose a risk of injury to those working on the scaffold.

    If a storm has brought down a power line, that could create a scaffolding hazard as well. Be fully licensed Being fully licensed—and working with contractors who are licensed as well—prevents injuries since everyone working on the site is aware of the potential hazards present and the best ways to mitigate them.

    The process of becoming licensed often involves education and training, which in turn helps your team work safely. Climb responsibly Those who scale your scaffolding should exercise proper safety techniques when doing so. One tip is to make sure employees always have at least three points of contact with the structure at all times, meaning either one hand and two feet or two hands and one foot.

    Whether you plan to have your own personnel erect a scaffold or hire someone else to, they need to be fully qualified and trained to do so safely. Taking the time to train your staff members on identifying scaffolding hazards and proper safety precautions when working at height—as well as making sure they have ready access to tools and PPE—can go a long way toward preventing accidents and minimizing liability.

Inspect scaffolding materials Before setting up your work platforms, you must inspect all of your materials before construction.

    A more robust system such as plastic mesh or wooden barricades is generally more effective and much easier to maintain. When members of the public could potentially move close enough to be struck by falling objects, creating barriers to prevent them from entering the area where objects can fall is a recognized best practice. Regardless of the type of falling object protection used, it is crucial that other individuals on the work site are aware of the overhead work.

    Electrocution Once again we look to preplanning and the competent person to assure there are no electrical hazards present during scaffold use. If this distance cannot be maintained, then the hazard must be de-energized or properly insulated by the power company. Lastly, all employees who work on scaffolds must have documented training. The training topics must include identification and prevention of fall hazards, falling tools and materials hazards, and knowledge of electrical hazards.

    Key Takeaways: Fall protection is required when work heights reach 10 feet or more. Provide proper access to the scaffold and never allow employees to climb on cross braces for horizontal or vertical movement. The scaffold competent person must be present when building, moving or dismantling the scaffold and must inspect it daily.

    Erect barricades to prevent individuals from walking under work platforms and place signs to warn those close by of the possible hazards. Maintain a minimum of 10 feet between the scaffold and any electrical hazard.
