(a)(i) Identification of specimens

• H: Shears (garden/pruning shears)
• I: Sickle
• J: Knapsack sprayer
• K: Wheelbarrow

(a)(ii) Two uses each of J and K

J (knapsack sprayer):

• Spraying insecticides, fungicides and pesticides on crops.
• Spraying herbicides to control weeds.

(It is also used for foliar application of liquid fertilizer and for spraying disinfectants on livestock houses.)

K (wheelbarrow):

• Carrying farm inputs such as manure, seedlings and fertilizer.
• Carrying farm produce and disposing of farm debris and waste.

(a)(iii) Three general ways of maintaining H (shears) and I (sickle)

1. Wash and dry them after every use to remove soil and plant sap.
2. Sharpen the blades regularly and grease or oil the metal parts before storage to prevent rust.
3. Keep the wooden handles away from termites and store the tools in a cool, dry place.

(a)(iv) Four precautions when using J (knapsack sprayer)

1. Wear protective clothing (overall, gloves, boots and a nose mask) while spraying.
2. Do not eat, drink or smoke while spraying, and wash the hands and face before doing so afterwards.
3. Do not spray when it is windy, and never spray against the wind direction.
4. Never blow a blocked nozzle with the mouth; clean it with a stick or wire, and wash the sprayer and protective clothing after use.
