Core Units: Safe, Compliant, Competent Carpentry
What the core units really test
Core units are the non-negotiable foundation: work health and safety, communication and teamwork, plans and specifications, measurement and setting out, hand and power tools, environmental and waste controls, and quality/legal compliance. Questions rarely ask for trivia; they test whether you can choose the correct first action or the correct control in a realistic scenario.
Concepts to master
Know the hierarchy of control (eliminate, substitute, engineer, administrate, PPE last) and be able to apply it to a task such as cutting masonry or working at height. Understand SWMS and JSA purposes, hazard identification and risk rating, incident and near-miss reporting, emergency procedures, and your duty to stop unsafe work. Learn plan-reading conventions: scale, datum, gridlines, elevations, sections, abbreviations, and the difference between nominal and actual sizes. Revise measurement tolerances, square and level checks (3-4-5 rule, diagonals), and the selection and inspection of hand and power tools, including guarding, leads, RCDs and dust extraction.
Traps in exam questions
- PPE is the last resort, not the first answer.
- A near miss is still reportable; questions often imply it is not.
- Nominal timber sizes differ from actual dressed sizes.
- "Make the area safe" usually precedes "report" in an emergency sequence.
- Plans are read at stated scale; never assume full size.
Worked example
A question asks the first step before cutting sheet material on a site saw. Rule of thumb: identify and control the hazard before starting the task - check the guard and riving knife, confirm RCD testing, set dust extraction, establish the exclusion zone, then proceed. Choosing "put on earmuffs" first is the classic wrong answer because it addresses only one hazard and relies on PPE.
