Dodgy Welding Unit

It is dodgy because the handpiece cable is only 1500 mm long! Therefore, the formworker must position this stinking, petrol-powered welder right next to himself so he can breathe in exaust fumes all day long.

When this issue was raised with management, the exact reply was: “That’s all they had”. That excuse does not make this safety issue go away! Send it back and tell the plant hire company not to send out unsafe, sub-standard equipment.

When requesting plant from a plant hire company such as this petrol powered welder, you should show that you know what you are talking about by telling them to supply long handpiece cables instead of just getting what CRAP they send you.

Why pay full price for sub-standard plant?

Don’t Be A Bozo

Don’t be a bozo and breathe in petrol exaust just because management cannot organize safe plant and equipment. You are better off getting fired than breathing in that shit for a day, a week or even months.

A common excuse construction supervisors give is “that’s all they had” or “that’s all we’ve got”. That’s is not your problem! Don’t be a bozo and use dodgy, unsafe plant and equipment.

Normally, when the red light is flashing and the safety boom is down at a railway crossing, the intention is that drivers wait until the train passes, the safety boom raises and the lights stop flashing. However, some people are in a bit of a hurry and take the chance.

Possible Conclusions

• The crane was too small for this lift.
• The load was being hoisted up too quickly not allowing for the water to drain.
• Maybe the windows were not smashed before lifting which prevented the last bit of water from draining at bottom end of the lift.
• Maybe the crane was not equipped with safety alarms, or the alarms were faulty, or they were manually overridden and therefore ignored.

Yet another unsafe looking truck I saw while doing Bridge Formwork at Port Adelaide. It should be noted that this is not some quiet back street, but a very busy main road.

Dodgy Unsafe Looking Truck Load

While doing bridge formwork at Port Adelaide, I was surprised to see so many trucks with either uncovered and/or unsecured loads driving down the street. It became normal to see some kind of uncovered or unsecured truck loads almost daily while working on this job.

Unsecured and Uncovered Truck Load

This photo was quickly captured after another formworker saw some of the load fall off the truck.

After reading about a killed worker as a result of being buried under wet concrete after a suspended slab collapsed, I wondered if some of us are too relaxed with our attitude towards Back-Propping.

The Do It Later Attitude

The photo below shows a small part of a formwork deck which in my opinion was done in a hurry due to the large number of incomplete Back-Propping assignments. This can only be the result of a flawed Work Method Statement.

Unsafe Back-Propping

You’ll notice that the Props are sitting on a flat timber which also needs to be propped before the concrete pour. The attitude here is “we’ll do it later”, or worse, “it’s okay” as it is. The problem with this attitude is that inside this maze of formwork frames, it can be very difficult to remember or spot all these important do-it-later jobs.

Often this do-it-later job is allocated to a Formworker experienced with spotting danger areas of a deck and back-propping accordingly. Too often this job is allocated too late only allowing time to insert the props, but not to tie them off with Scaffold Tube and Clamps (Fittings).

Top is Back Propped, bottom is Not

The other reason that this finish-it-just-before-the-concrete-pour attitude is flawed is because the deck will continue to be loaded with additional bundles of plywood, timber and steel well before the concrete pour day. Heavy compressors could also be landed on the deck along with big bundles of pipes for the concrete pump.

What this means is that it is possible to overload and collapse parts of the deck even before the concrete pour day if the Back-Propping is incomplete.

Do It Now

Never leave these Back-Propping jobs incomplete. Do them immediately and completely as you go. This procedure should be placed in the companies Work Method Statement in order to ensure that your supervisor or leading hand can not take you to another job before the Back-Propping is 100% complete.

Communicate

You should also communicate with the Deck Head informing them of the areas where construction materials should not be placed. Deck heads should also inform Doggers the correct way to lay the Dunnage/Gluts.

For example, the Dunnage should always go across several Joist timbers instead of longways in between the Joists where the loaded Dunnage could easily penetrate through the plywood. This mistake is made very often so keep an eye on beginner doggies with no formwork experience.

Secure Those Props

Too often props are not nailed at the top because there is simply no way to reach up there safely. A single prop on it’s own falling over can threaten life or limb as well as be responsible for the collapse of a formwork deck.

Even if the props are nailed to the Header, there is no guarantee that the Header is nailed properly to the Joists. For this reason, props should be secured with scaffold tube and clamps back to the frames which will ensure the props remain in the desired position.

Plan To Minimize Back-Propping

A lot of Back-Propping in the above pictured deck could have been eliminated altogether by planning the layout of the frames better. If frames are erected at the minimum required span or less, the need for Back-Propping will be reduced to a minimum.

Of course this method assumes that the formwork company does not take short-cuts by deliberately using lots of unnecessary props because there is a shortage of Frames. The general rule for this should be if a Frame can fit, put it in there.

Cause And Effect

Because every effect has a cause, be assured that it is somebodies fault that the worker engulfed in wet concrete was killed!
