Most candidates were able to state the precautions to be taken while using the given items.
However,they were unable to:
-name the woodwork machine on which each of the devices is found;
-name the two safety devices used on the circular saw bench;

(b)Naming Woodwork machines
(i)Crown guard – circular saw bench/dimension saw
(ii)Chipbreaker – Mortiser
(iii)Bridge guard – surface planer
(iv)Thrust wheel – Bandsaw
(v)Tailstock – wood lathe
(c)Naming Safety Devices used on the circular saw bench
-Push stick
-Push block
-Crown guard.
(d)Stating the function of parts of circular saw bench
(i)Riving knife
-To prevent the timber from binding on the saw blade while being cut or
-To guard the back edge of the saw blade
