The term ‘hand tools’ describes those tools that are powered by you. They don’t rely on an external power source to drive them. While many of these tools have a powered option which can be easier to use, there are times when power is unavailable or you need the added control of the hand tool option.

This isn’t an exhaustive list of all of the tools that you will use. We have focused on those tools that it’s likely that you will come across during the first year or so of your training. Take the time to familiarise yourself with any new tool before you use it. Make sure you know how to use it safely, how to check it for serviceability, what PPE you should be utilising and how to clean and store it. Ensure that you utilise appropriate PPE, follow the manufacturer instructions and work safely.
 

Suitable for: Retractable tape measures are most suitable for measuring distances of less than 10 metres. Characteristic/ descriptor They have an inbuilt mechanism which automatically winds the measuring tape (called the blade) into the housing. 

Limitations: Use can be limited by damage to the blade, the blade not being long enough, difficulty obtaining an accurate enough measurement (can be caused by stretching to the hook, drooping in the tape etc), lack of accessibility and so on.

PPE: Safety glasses.

Serviceability: The blade should be free of kinks, the mechanism should work effectively, measurements must be legible, blade should be long enough for the task and the hooks should be checked for stretching or damage.

Correct use: Ensure that the tape is flat against the surface. The tape should be horizontal or plumb if measuring across an open span. Enlist the help of a second person to adjust for damage/stretching to hook.

Special notes/precautions/WHS: Ensure that metal tapes are clean and dry before retracting.

For more information on using a tape measure watch the video below.


 

Suitable for: Measuring longer distances (usually over 10m). These tape measures are retracted manually.

Limitations: Use can be limited by damage to blade, the tape not being long enough and high winds.

PPE: Safety glasses.

Serviceability: The blade should be free of kinks and damage, the mechanism should work effectively, measurements must be legible, blade should be long enough for the task and the hooks should be checked for stretching or damage.

Correct use: Ensure that the tape is taught and that it is horizontal or plumb if measuring across an open span. Enlist the help of a second person to adjust for damage/stretching to hook.

Special notes/precautions/WHS: Ensure that the tape is clean and dry before retracting.

For more information on using a tape measure watch the video below. 

 

Suitable for: Measuring and marking straight lines.

Characteristic/ description: A folding or steel ruler has the following components:

  • inbuilt extender

Special notes/precautions/WHS: Test for accuracy prior to use (against set square/triangle).
 

Suitable for: Marking a straight line between two points, marking a straight, level line between two points.

Characteristic/ description: Stringlines are a relatively simple device made of string and a plumb bob or plumb line, which is a small piece of metal that weighs down the string to measure the distance between the two points. 

Limitations: A string line may not be suitable where you are unable to anchor it or where there is an obstacle in its path.

PPE: Standard precautions.

Serviceability: Ensure that it is tangle free.

Correct use: Ensure that line is secured. Make sure that there is no sag in the line and that it is properly attached. 

For more information about how to use a string line, watch the video below.

Fun fact! 

A string line is one of the oldest of basic hand tools and plumb bobs are said to be used by the Ancient Egyptians during the building of the pyramids. 
 

Suitable for: A chalk line is used for marking a long, straight line on flat surfaces.

Characteristic/ description:  A chalk line is a device with:

  • retractable string 
  • geared reel 
  • plastic casing that disperses the chalk when taking measurements. 
  • string at the end with a hook like attachment which can be used to secure at point of measurement. 


Limitations: A chalk line may not be suitable where the surface is uneven or where there is an obstacle in the way.

PPE: Standard precautions.

Serviceability: Check that the chalk reservoir is filled.
