This is has been taken from your Knowledge organiser.

You can see and read the workshop safety rules here   https://pcsaengineers.uk/the-workshop-rules/

Read through the safety rules.

Choose 6 safety that you think are the most important rules

Write them neatly into your book

Write sentences that describe why you think these three safety rules are the most important rules to follow.

TASK 2,

The Rose is made from mild steel which contains approximately ________ carbon making it _____e and _____e. M________l has a low t_______e s_______h compared to other metals. It is relatively i__________e and can be formed quite easily using workshop tools and equipment for example metal snips, ball pein hammer, cold chisel, centre punch and formit machine. Mild steel must always be secured in a hand vice or machine vice when being drilled.

C__________g of steel is done when the metal is at room temperature. Cold working of the steel will make the steel h______n and become b_______e.

To achieve the fine organic details of the rose petals, the metal is h_________d. The mild steel is heated to red heat increasing its d_______y and m________y. Long nosed pliers are used to  shape and form. Take care with hot metal !

 Copy out the above into your blue book filling in the missing words and phrases.
