Safe Working Practices

Gbogbo ọrọ náà

A graphics workshop looks gentler than a metal shop, but a craft knife, a guillotine, a laser cutter and a hot glue gun all bite. Safe working practice is the set of habits and equipment that lets you cut, fold, print, glue and machine graphic materials without hurting yourself, the people near you, or the product. It is examined directly, and it is the first thing a good designer-maker thinks about before picking up a tool.

This note covers the safe use of the hand tools, power tools, machinery and computer-aided manufacture (CAM) equipment found in graphic products work - from the steel rule and craft knife to the rotary trimmer, vinyl cutter and laser cutter - and the personal protective equipment (PPE) you select and wear for each task. The aim is not to memorise rules for their own sake but to understand the hazard behind each rule, so you can work safely with any tool you meet.

Ebumnobi

  1. demonstrate safe use of hand tools, power tools, machinery and/or computer-aided manufacture (CAM) equipment
  2. select and use appropriate PPE (Personal Protective Equipment) when working practically.

Akọmọ Ojú-ẹkọ

Before any specific tool, learn the structure that all safety rules share. A hazard is anything with the potential to cause harm - a sharp blade, a hot nozzle, a laser beam, solvent fumes. The risk is how likely that harm is and how serious it would be. A control is what you do to reduce the risk: guard the blade, ventilate the fumes, wear goggles. Every rule in the workshop is a control aimed at a hazard. When you can name the hazard a rule is protecting against, you can apply the right control even with an unfamiliar tool, which is exactly what the exam tests.
