Self Analisas of Sub Floor

At my work place we have done quiet a few decks and have a fair idea of how it all goes together, but having recently learnt about setting out and using profiles it made life alot easier. I drew a scaled design of what i was going to build which again made things easier because i could get a visual of how things were going together. Once we got our levels and set up the profiles every thing just fell into place. Again i thought this excersise from the couple of work sheets to the design and then the practical was a very valuable and enjoyable excersise.

Self Analysis Setting Out And Leveling

I had never done any setting out before and was very interested about it all. I learnt about profiles and the way they work was pretty self explanitery but also very practical. I think that this is gonna be very usefull when im a tradie and use the fundamentals behind setting out in a whole range of areas in the industry.the things i did well i think was every thing from start to go and trying to be excact with all of the measurements and hights. out of ten i would of givin us a 8 or 9 again for the accurasy and speed we finished it in.

Self Analys Step Ladder

The step ladder was another good project for developing good hand skills with chizzles and also a good excersise to develope working off a plan. I learnt that when drawing the plan you have to be spot on and very neat. When im a tradesman it will come into use when i have to design jobs and be neat and exact. The things i thought i did well was neatness of the cuts and joins and all the little extras when finishing off like, extra grooves in the steps, a coat of varnish, and stamping my name and other words on it. I didnt do as well as i proberly should of with the drawings but they were still good and neat. Out of ten i proberly would of givin my slef maby a 71/2 to 8 for speed and accurasy. Over all i thought it was a good excersise.

E diray

15/10/07 we drew up the design of the step ladder then worked through work sheets on quoting msds and abestoses, then researched pine and answered questions on that.
16/10/07 I carried on with the msds excersise and made a start on the step ladder which i quickely realised may be a bit harder and take a bit longer than i quoted.
17/10/07 today was devoted to finishing the step ladder and making it look nice, i realised today that i did under quote the labour time.
18/10/07 We were in the class room until lunch working through plan reading excersises which showed me a bit more that i already knew, we then did some scale sheets. after lunch we went out side and did some leveling using a spirit level line level dumpi and a water level which was good because i had never used one of thoes before.
19/10/07 Today we did some plan reading and levels excersises which were good to learn more about using the lazer level and then transfering our results to paper in a scaled drawing.
22/10/07 It was all about setting out today and learning the best way to do so, as a class we went through excatly how to set out for a house. i thought it was a very good excersise and usefull to many areas of the trade.
23/10/07 I did a practical assesment today about all the setting out things we learnt yesterday it took a little while but passed with no dramas.
24/10/07 Today i did a couple of sub floor framing work sheets and then did three scale 1:1 drawings of three different sub floors, i again found it very useful and learnt a couple of extra things that i didnt know.
25/10/07 Today i quoted on building a subfloor and did the take off then rung culitys and recieved some prices. i then worked out how much the materials would cost and estimated how long it would take and figured out a price, making sure i wasnt going to under cut my self this time. I really enjoyed this because i think it will be relitave to when im working for my self.
26/10/07 Today i put my plan of the sub floor into action and managed to complete it sucessfully and with heaps of time to spare. If this was real world i would of made good money today and gained more clients through my methods i was taught.

CCA Asignment

Its used in areas that may be exposed to weather eg pergolas fences park benches, or areas the may be exposed to white ant fungi or bores.

its hazardous because inhalation of excessive amounts dust may cause tempory breathing difficulties and irrationof the eyes and skin.

Its a good idea to wear PPE and to cut in a well ventilated area.

CCA should be stored in well ventilated areas away from flames or sparks. No special transport requirements are considered nessecary.

MDF Assigment

Uses: -It may be used to make display cabinets, wall-panels and storage units.

The health risks are generally based on the machining and dust-particle control while working with MDF. Once MDF has been finished as furniture, or whatever, there is little or no acknowledged health risk.

If formaldehyde in MDF is being used, and cut or worked, at your workplace your employer should first try to use a safer material. If there is no alternative to using fibreboard then your employer should consider low emission board. Some board manufacturers are advertising low formaldehyde or zero formaldehyde emission boards made to the stringent German 'E1' standard. This standard is currently being reviewed by the European Union.
Where dust cannot be eliminated, the employer has to introduce control measures which will adequately reduce dust levels. This will require adequate ventilation. The most effective control measure is Local Exhaust Ventilation. The exhaust mechanism is normally attached to the workstation where board is being cut. As wood fibres are released from the board the exhaust should remove them from workplace air. This ensures that most of the dust is removed from the atmosphere as board is worked. Your employer should also keep the workplace clean and ensure that the workplace is free of any dust. Gloves should be provided to avoid formaldehyde coming into contact with the skin, and suitable masks should be provided to avoid inhalation or ingestion of fibres.

Storage: Dont store where it could get wet or mear a source of ignition. store in low humidity ant temperature high temp and inadequate ventalation could allow the development of formaldehyde vapors in the storage area.

Material Safety Data Sheet

An MSDS is a document containing important information about a hazardous substance and must state:
a hazardous substance’s product name
the chemical and generic name of certain ingredients
the chemical and physical properties of the hazardous substance
health hazard information
precautions for safe use and handling
the manufacturer’s or importer’s name, Australian address and telephone number.
The MSDS provides employers, self-employed persons, workers and other health and safety representatives with the necessary information to safely manage the risk from hazardous substance exposure.
It is important that everyone in the workplace knows how to read and interpret a MSDS.
