    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.

    When used properly, scaffolds can save significant time and money. Though they are convenient and necessary, there are four major hazards associated with worker injuries that everyone needs to be aware for proper scaffold safety.

    Falls Falls are attributed to the lack of guardrails, improper installation of guardrails and failure to use personal fall arrest systems when required. These contractors are increasing safety margins by exceeding the minimum requirements of the OSHA standards. Lack of proper access to the scaffold work platform is an additional reason for falls from scaffolds.

    Access in the form of a secured ladder, stair tower, ramp, etc. The means of access must be determined before erection of the scaffold and employees are never allowed to climb on cross braces for either vertical or horizontal movement.

    Scaffold collapse The proper erection of a scaffold is essential in preventing this particular hazard. Before erecting the scaffold, a number of factors must be accounted for. The amount of weight the scaffold will be required to hold including the weight of the scaffold itself, materials, and workers must be considered. Foundation stability, placement of scaffold planks, distance from the scaffold to the work surface, and tie-in requirements are just a few of the other items that must be considered prior to building a scaffold.

    Scaffold Competent Person A knowledgeable individual who can perform preplanning will reduce the chances of injury and save money for any task. However, when building, moving, or dismantling a scaffold, a knowledgeable person, also known as the scaffold competent person, must be present. A competent person must also inspect the scaffold daily to ensure the structure remains in a safe condition. Improper construction can lead to a total collapse of the scaffold or falling components — both of which can be fatal.

    Struck by falling materials Workers on scaffolds are not the only ones exposed to scaffold related hazards. Many individuals have been injured or killed due to being struck by materials or tools that have fallen from scaffold platforms. These people must be protected from falling objects. OSHA requires that this is done one of two ways. The first is to install toe boards or netting on work platforms to prevent these items from falling to the ground or lower level work areas.

    The other option is to erect barricades that physically prevent individuals from walking under work platforms. Caution or Danger tape is often used in an attempt to keep people away from overhead hazards but is often disregarded or taken down creating possible struck by hazards. 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. Ensure all employees working on scaffolding have had proper training. Scaffold safety starts from the ground up. Only safe work conditions and actions will prevent unnecessary injuries when working on these ever changing structures.

    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.

    Scaffolds are important not only for new construction but for demolition and repair work of building also.

    Scaffold Safety – 4 Common Hazards

    Parts of scaffolding Parts of scaffolding Standard These are vertical members of the framework, supported on the ground ordrums, or embedded into the ground. Ledgers These are horizontal members, parallel to the wall and right angles to the standards and support the putlog.

    Braces These are inclined members fixed diagonal. Putlogs These are transverse members, placed at the right angle to the walls with one end supported on the ledger and another end on the wall. Volts Volts are used to bind all the parts of the scaffold to withstand load and make a frame structure. Types of scaffolding Single scaffolding or- brick layer scaffold or putlog scaffold. Single scaffolding Single scaffold This type of scaffold is cheap and common for wall construction.

    Most of the members used for this type are made of bamboo poles except the working platform. This type of scaffold is erected by driving into the ground a single row of the standard at 1. The feet of the standard is also rested on base plates fixed to a soleplate. Transverse horizontal putlogs at a right angle to the wall are tied at one end to the ledgers and the other end inserted securely into the wall.
