How to assemble a scaffolding structure

1) Protection: Place fall protection systems for workers before beginning assembly. Take care of worker safety measures with care. Sort the elements according to how they will be used. Pay attention to units with possible defects. Have elevators to lift components.

2) Prepare the scaffolding area: moisten, firm and compact the area before leveling to begin assembling the scaffolding structure. Support the vertical sections of the scaffolding with wood. Place supports so that the vertical components are centered and balanced correctly on the base.

3) Assemble the first level of scaffolding: Present two vertical structures at specified distances and join them with connector structures. Place the diagonal clamps to keep the scaffolding at 90º and in balance. Join the clamps with suitable gaskets and the supports for stacking. Place the first floor planks. The work base must be covered with no holes greater than 250cm. Click Here for STI Course

4) Railings must be installed if the scaffolding structure is higher than 3 meters. The top rail must be 96 – 115cm above the work base. The middle rails are important. Place screens or nets to prevent objects from falling. Fasten each scaffold platform at 360cm intervals.

5) Repeat the previous steps until completing the first level. Raise the scaffolding structure to the next level with a material lift. Join the vertical parts to the lower ones with coupling elements and pins. Install clamps and cross clamps. Install elements from step 4. Complete each level of scaffolding until the total height of the building is achieved. Attach each floor of the scaffold to the building at 360cm intervals.

AVOID DISGRACE: DO NOT MOUNT SCAFFOLDING NEAR THE LINES

Electricity does not allow improvisations. It is risky to work near medium and low voltage lines, so certain safety measures must be taken to avoid accidents.

In civil works work, when machines and or mechanical means coincide with Medium Voltage or Low Voltage electrical networks, above ground or underground, in addition to the specific risks due to the handling of machines and equipment, there is the risk of shocks due to electrical contact with conductors of the lines.

In these service or construction processes, scaffolding is often used to carry out work at height, which implies certain risks that must be taken into account to avoid unfortunate accidents.

The consequences on people of the intensity of current that circulates due to electrical contact can be: death due to asphyxiation, respiratory arrest or cardiac arrest; severe internal and external burns; muscle stiffness; fell from a height.

Electrical shock occurs when a person directly or through machinery or elements comes into contact with or gets excessively close to the conductors of a live overhead or underground power line.

It is not necessary to come into contact with bare conductors for an electrical accident to occur. Excessive proximity to a live conductor will produce an electric shock that will lead to an accident.

The distance at which the discharge originates depends on the nominal line voltage and atmospheric conditions.

It must be taken into account that the higher the voltage, the greater the distance at which the discharge occurs.

The worker who makes contact with the line conductor, any worker who touches his injured colleague while receiving the shock or the element through which contact is made (crane, vehicle, etc.) may suffer injuries while the electric shock lasts. machinery, ladder, etc.) or that worker who approaches or moves away from the accident area.
