last three days of tafe.
On the last three days we have been through a variety of subjects. we learned the basic on:
carpentry materials
setting out and leveling
timber floors
occupational health and safety
power tools
how to do a costing chart for basic timber floors
At the end of this we had an exam on it all. i also finished sanding off my step ladder.

first day of tafe
on the first day of tafe we had to draw up a scale drawing of our step ladder. after we had done that we had to do an invoice and cutting sheet. then we began marking out and cutting the legs of the step ladder.
day 2
we continued making our step ladder. i finished cutting out the front legs. Next i marked and chiseled out the grooves in the legs for the step to sit. Then i cut out the steps and plained down the backs. after my steps were made i drilled holes and screwed my steps into the legs. I then marked out my top and cut it to size and chisel out the groves which it sits on.
day 3
day three was in the workshop again. i fit my top on my ladder to start off with, by using four screws to hold it. i then started cutting my legs to size. i marked out where i needed to round off one side and started cutting the corners off. then i took it over to the belt sander and rounded the rest off smoothly. after that i got the angles using a bevel to draw the angle that the feet were to be cut on. then i cut them using a hacksaw.
i then bolted on the back legs and started cutting the back braces. i fitted the back braces with screws and a drill and then made my leg support. when i had connected the leg support that was the last step before sanding.

MSDS assignment
Part 1
Describe:
A. material safety data sheet
An MSDS is a form which shows the hazardous properties in a certain substance.
B. what is in an MSDS?
An MSDS provides workers with all they need to no about the substance including how to handle it properly, what chemicals are in it, all of its physical data, how to store and dispose of it and what protective equipment to wear.
C. why weed need MSDS
We need these sheets just to be familiar with what we are handling and encase anything goes wrong it will show exactly how to fix it.
Part 2.
Jarrah timber.
Where would you come across this in the building industry?
You would come across jarrah timber a lot in the building industry. It is used for housing, furniture making, decking, framing of doors, windows, floor boards. You will commonly see it most in houses, shops, businesses, playgrounds ect. This type of wood is normaly used by carpenters, builders, joiners ect.
When is it likely to be a hazard to your health?
Jarrah isn’t realy very hazardous. You might get the odd splinter or when your cutting it the saw dust could get into your eyes and noes causing them to become irritated.
Reducing the hazard
To stop getting dust in your eyes and mouth the best thing to do is wear a dust mask and safety glasses. Some power tools also have dust reduction systems or bags that catch the dust.
What does MSDS recommend for handling and storage?
When storing jarrah make sure you put it in a dry area so it doesn’t get wet an bow. Also stack neatly with the larger pieces at the bottom.
Risks to my health?
Although saw dust can be harmful if it gets in your lungs I don’t consider jarrah very harmful to my health. Saw dust is easily avoidable and generally wont harm you to much.
Fibre cement sheeting
Where would you come across this in the building industry?
Fibre cement sheeting would be found in most places in the building industry. It is a common material and is used for things such as walls, floors and general housing.
When is it likely to be a hazard to your health?
Fibre cement sheeting can be very hazardous to your lungs. Any dust that comes out of it whilst cutting or drilling it can get into your lungs. The dust contains silica particles which are known to cause scar tissue to develop in the lungs. It can also cause silicosis. This is a disease of the lungs.
Reducing the hazard
When working with fibre cement sheeting it is a must that you wear a dust mask. In larger factories that deal with fibre cement sheeting a lot they will have to have a raspatory system in place.
What does MSDS recommend for handling and storage?
Try and keep exposure to the dust fibres as low as possible. When sing it make sure you’re in a well ventilated area. Try and avoid spilling or creating dust and do not store near food drinks or cigarettes.
Risks to my health?
I think when handled incorrectly and when the right precautions aren’t taken place eg dust mask, fibre cement sheeting can be very harmful to your health. It might not effect you straight away but could have devastating effects down the track.
Part 3
You are doing a roof extension to a house built in 1952. Name three areas of the house that your work may come in contact with asbestos.
In 1952 you could come into contact with asbestos in walls, in old stoves, ceilings, fences and more.
When and why is asbestos considered dangerous?

In 1952 you could come into contact with asbestos in walls, in old stoves, ceilings, fences and more.
When and why is asbestos considered dangerous?
In the 1930s people figured out asbestos was dangerous because a lot of workers that were using it were dying young. If fibres get into your lungs it can cause lung cancer or melanoma of the lining around your lungs.
How could you minimise the chances of being exposed to asbestos fibres?
From what I no I think exposure to asbestos is life threatening and should be avoided at all costs.
