In our last article we discussed how important safety considerations were when doing home renovation and home construction projects. Do not hurt yourself while renovating or building your home. Safety tips.
​
Accidents happen quickly and far to often, especially for the inexperienced builder, or someone not using the correct equipment, or when a home builder is tired, in a hurry, or trying to save money. No time or cost saving is worth the risk of a serious injury. ​

In this article we look at more safety tips:
  • Ensure that live services have been disconnected where there’s a possibility you could damage them. Turn off gas and power when you’re working near electrical wires and gas pipes. Ensure these can’t be turned on accidentally by somebody unaware that you’re working near them.
  • Never leave live electrical wires exposed.
  • Keep all work areas clean and tidy. Rubble and material lying on the site creates trip hazards. Bits of wood with nails and screws sticking out are a leading cause of injury.
  • Use the right tool for the job. Often injuries are caused when the wrong tool is used, or when a tool is used which is too small for the job.
  • Check all equipment every time before use to ensure that it hasn’t been damaged and that all the safety features are in place. Broken equipment should be fixed by the appropriate repairers. Don’t use faulty equipment.
  • Ensure that all work areas are barricaded. Regrettably serious injuries have been caused when children have been playing on construction sites.
  • Make sure that materials are stacked properly. Heavy objects leaning against a wall can easily be knocked over falling onto someone.
  • Check that materials that could be blown loose in a storm are secured at the end of the day or when severe weather is on its way. Stacked materials could be blown over and loose materials such as metal and tin sheets can be blown about, turning into dangerous missiles.
  • Take care not to damage electrical extension leads. All electrical cables should be checked and equipment with exposed wires, damaged electrical plugs and loose connections should not be used until the item has been properly repaired. Needless to say electrical equipment shouldn’t be used in the wet and electrical leads should not lie in water.
  • Never leave dangerous tools lying around where children could accidentally, or intentionally, turn them on causing injury.
  • Care must be taken when doing any demolition work.
    • No load bearing walls must be demolished (or have pieces cut from them) unless an engineer has inspected the wall and all permanent and temporary supports recommended by the engineer have been installed. Read Before removing walls or adding new windows and doors check your house will not fall down
    • Before cutting through any bracings in the walls or roof structures first obtain clearance from an engineer.
    • Care must be taken to ensure that the portions of the structure left standing are stable. Unfortunately, some demolitions are poorly planned so that the demolition work is only partly completed when the rest of the structure becomes unstable and collapses, often causing serious damage and injury.

Do not hurt yourself while renovating or building your home. Safety tips.

​Construction is an inherently dangerous job. Unfortunately injuries caused by people carrying out do-it-yourself maintenance and renovation tasks at home are one of the leading causes of hospital admissions. An injury to yourself could, in the worst case, lead to death or permanent disability, but at the very least will lead to pain, inconvenience and additional costs. Some people are highly dependent on the full use of parts of their body, so consider how losing a finger or suffering a hand injury could impact a surgeon or a dentist (even if they lose the use of a finger or their hand for only a few days, the lost earnings could far outweigh the savings of doing the work themselves). How dependant is your job on your fingers, limbs or eyes?

Important home renovation safety tips include:
  • Working at heights is a leading cause of injury. Always ensure that when working off ladders these are structurally sound, that they’re placed on a firm footing and are held in place so they can’t slip or fall over. Where possible another person should anchor the ladder.
  • When working on an access scaffold always ensure that the scaffold is on a firm footing, where one leg can’t suddenly settle into the ground causing the whole scaffold to tilt. Scaffold legs should have base plates and even timbers under them to distribute the load. The planks on scaffolding should be firmly attached so they can’t accidentally tip, or fall off. Scaffold towers should never be higher than three times their width. If the tower is higher it should be tied to a wall, or have side props to prevent it toppling over. Never overload scaffold platforms. Don’t erect scaffold on the edge of excavations.
  • Wear proper personal protective equipment.
    • Your eyes are valuable so it’s vital you wear glasses that provide full protection so that dust and other construction debris can’t enter your eyes. Also, some solvents and liquids can damage the eye should they splash into your eye.
    • Safety shoes are essential. They help prevent trips, slips and falls, they’ll protect your feet if something heavy or sharp falls on them, and protect the soles of feet should you stand on a sharp object.
    • Gloves provide protection to hands.
    • Inhaling dust and fibres from cutting can lead to long term health problems, including lung cancer, so dust masks are necessary when cutting or drilling into materials which generate dust.
    • Some products, particularly epoxies, solvents and glues can give off noxious fumes, so wearing a proper breathing mask appropriate to the task is essential, and only mix and use them in ventilated areas.
    • Safety harnesses are essential when working at heights where there’s a possibility of falling. These need to be anchored to a firm support that will hold and arrest your fall.
    • Darkened visors must be used when flame cutting or welding.
  • Always get an injury treated properly, then take precautions to prevent dirt getting into the wound. Even a minor cut finger can become infected and end with a protracted hospital stay, or even worse an amputation of a finger.

Reinforcing Steel what you should know

11/8/2020

Reinforcing steel comes in bars which are normally tied together to form a cage. The bars come in different grades or strengths and can be smooth or deformed (with small ridges). Sometimes the reinforcing is in a ready-made mesh which comes in standard sized sheets or rolls.
​
Reinforcing gives concrete structures their strength and also prevents shrinkage cracking. Engineers design the reinforcing that goes in the structure. It’s important that the reinforcing is placed in the positions indicated on the reinforcing drawings, and that where the reinforcing (or mesh) joins it overlaps with the next bars. It’s obvious that the right size bars (or mesh), of the right grade and deformations is used, otherwise the structure could fail.

Reinforced concrete is usually used in foundations and concrete slabs in houses, for 2nd floor slabs and balconies, and for concrete roofs.

​Reinforcing should not be too close to the bottom, sides or top surface of the concrete. Usually the reinforcing is designed to have a minimum cover (distance from the outside edge of the concrete) which could be 25, 30, 40, 50 millimetres (one to two inches). The cover often depends on the structure and the conditions the concrete will be exposed to. Harsh conditions near water, and especially sea water will require a bigger distance from the edge of the concrete so that the reinforcing is better protected. Reinforcing that’s too close to the edge of the concrete could mean that the concrete can’t get around and under the steel bars so the bars could be left exposed, which means that the reinforcing will corrode and also that it won’t do its job. Water also penetrates the first layers of concrete and steel close to the surface will rust. Rusted reinforcing expands, which then breaks the concrete around the steel. This is unsightly and weakens the structure. Rusting reinforcing also leaves ugly rust marks on exposed concrete.
Picture
Unfortunately, sometimes reinforcing isn’t adequately supported and when the concrete is poured workers walk on the reinforcing squashing it deeper into the concrete and below where it should be. Reinforcing which isn’t where it should be in the concrete can result in a weakened structure and cracking on the surface. Always ensure mesh reinforcing layers are fixed correctly so that they stay in the right position, even after the concrete is poured.
​
For reinforcing to be effective it should be clean, not contaminated with grease and oils and relatively free of rust so that the concrete sticks to it. When reinforcing is delivered to the site it should never be stacked immediately on the ground, but should rather be raised off the ground on timber poles. Reinforcing should be used as soon as possible after it’s delivered, certainly within a few weeks.

Generally an engineer should inspect structures before concrete is poured to ensure that the correct reinforcing has been used and it’s fixed in the correct place.
​
Sometimes engineers replace steel reinforcing bars with fibres, which could be steel or synthetic. The fibres are mixed into the concrete during the mixing stage.
