5. Organise the necessary procedures to help a person when an incident occurs in an engineering workshop.

• Personal Incidents:-  e.g. Cuts/wounds, electric shock, unconsciousness, physical/chemical burns, sprains and strains, fractures, foreign object in the eye.

 
2. Explain safe work practices and procurers when carrying out an engineering activity.

• Safe work practices e.g. Making sure equipment is isolated before setting it up; Using appropriate holding devices; Wearing protective clothing; Keeping work area free from waste material, tools and equipment; Guards are in full working order

 
2. Carry out preventative measures required for maintaining a safe work environment during an engineering activity.
Preventative Measures:

• Mechanical: e.g. wear the appropriate PPE,  use the suitable tool for the proper job, visual inspection of the tool, work to laid down procedures, do not remove or disable guards, do not remove safety devices on machinery;


• Electrical and electronic e.g. wear the appropriate PPE, check for wear on electrical cords, check appropriate fuse rating.


• Physical:- e.g. wear the appropriate PPE, do not wear jewellery, tie loose hair, remove loose clothing, proper ventilation, use sunblock in direct sunlight;


• Chemical e.g. wear the appropriate PPE, protect from direct sun light, obtain special instructions before use, do not spray on an open flame, wash thoroughly after handling, store chemicals in a safe place, report and do not use unlabelled containers;


• Ergonomic e.g. adjust workstations, proper lifting techniques, adopt good posture, avoid repetitive work movements, take frequent breaks, use appropriate tools to enable neutral posture;


• Environment e.g. permit to work, inspection of site dangers, hand rails, make sure that scaffolds are certified, do not touch bare conductors, good housekeeping, follow signs, adhere to symbols and colour codes, good ventilation, follow lock out-tag out procedures;

 
Subject Focus 3. Develop skills in using machinery safely
 
6. Identify preventive measures to minimise risk when using machinery.

• Machinery e.g. Lathe; Sanding machine; Pillar drill

 
7. Select from a given list ,parts and components of machinery to be checked before being used safely.
