How Capturing Visual Images has helped Scaffolding Operations

An estimated 2.3 million construction workers (roughly 65% of the entire construction industry), work on or with scaffolds*. Observers would agree that scaffolding operations involve a complex asset base of resources (both man and material). Moreover, scaffolding operations entail many complex but mandatory safety processes that have contributed to losses in kind and cash if not followed accurately.

One clear observation in scaffolding operations is the need for identifying work sites and its complexities. Any normal scaffold cycle would include requests, permits, multiple approval points, certificates, maintaining of records and multiple communication with authorities at different levels. Most of these systems are paper driven and hence lack the accuracy that minute detailing can provide.



How Floor-maps are Reducing Losses Incurring from Scaffolding Operations

Scaffolding operations entail many complex but mandatory safety processes that have contributed to losses in kind and cash if not followed accurately. One of the most common losses observed, is in relation to material losses involved in the erection and dismantling operations of scaffolds.

Most of the leading contractors (heavy infrastructure and engineering) have large areas covered in a single project. Such an operation might require multiple scaffolding sites. Most of these operations entail paper driven systems that take a whole lot of time and are cumbersome. Sometimes it becomes extremely difficult for authorities to accurately track the existence (or non-existence) of scaffolds. Often scaffolds are dismantled only to know that a similar one was required at that very same spot. This may result in huge operational losses for the organization.



A Mantra to Effective & Successful Training Program

We all remember the iconic image of 11 workers sitting on a beam, 69 floors high of an under construction Empire State Building in 1931. We remember that image for many different reasons, mostly positive but from a safety perspective, we remember it for one thing and one thing only i.e. how unsafe the work practices used to be. Not just that, but safety wizards have been using that image as what ‘NOT TO DO’ at work in their safety seminars and trainings.



Force – Pushing it in a Pulled up World

In the world of safety, we all come across controversial questions like “Is Pulling the load easier than Pushing”? Or “Is pushing safer than pulling”?

At the workplace, I have always followed the mantra that heavy load should always be pushed to be moved. Now it is imperative that some readers will disagree to that conclusion and may refer to that calculation of force (as shown below) against relative motion at an angle where pulling the load is easier due to reduction of frictional force.



Versatile Protection by ELCB- e.g. 4-pole type, Even when fed with 3 Single-Phase Independent Power Supply Sources

1. A 4-pole ELCB, providing passage to balanced 3 phase & 1 neutral through it’s torroid forming the primary winding of the sensitive current transformer, serves very effectively to guard against leaking current of the order of 5 mA – 30 mA -50 mA and beyond , with prompt clearance of the leaking circuit in a matter of 30-50-100….m.seconds.The consumer side is distributed 3-phase loads plus some single-phase loads. Problem arises when the main 3-phase, 4 wire balanced supply line is switched off by the supply agency and alternative stand-by 3-phase balanced supply is not available.

The gap may be asked to fulfill with 3 Nos separate sources of 1-phase diesel generators, the voltage of which shall be unequal, unbalanced in phase, rather placed at random phase displacement, may be filled with harmonics and even some d.c. components, connected in star with common neutral (earthed) as shown in below vector diagram.
