Safe Manual Handling: Three Steps To a Safer Workplace
In the past safe manual handling training was all about how to lift things correctly. However current practice is to minimize the risk of manual handling injury through a three step process: 1. Identify hazardous manual handling tasks; 2. Assess risks involved in hazardous tasks; 3. Risk control – measures to reduce or eliminate risks. With the aid of an ergonomist and a physiotherapist, this program demonstrates how to make a workplace safer using some basic principles and procedures.

Safety in Technology Workshops: Working with Wood, Metal and Plastic
Because technology workshops can be very dangerous places, students need to be comprehensively educated about safety. Based on extensive research with teachers and DOE advisors, this program concentrates on those areas in which students can make a significant contribution to their own safety, such as the use of personal protective equipment. Many potential hazards are discussed, from keeping the floor free of obstacles to the dangers of excessive noise, electrical tools and airborne dust.

Manufacturing and the Product Cycle: A Case Study of Moran Furniture
All products go through a development process from conception to final evaluation. In this program, Moran Furniture explain the stages in their product cycle – the process that creates their award-winning sofas. The product cycle is examined from the initial concept through product design, production and distribution, marketing and sales. We also consider the value of further evaluation and modification of the products. Students will gain an understanding that research and development is an ongoing issue and continues right through the product cycle.

Building Bridges – The Physics of Construction
The nuts & bolts of building bridges. What factors to consider when you build a bridge and what’s the Physics behind them? Introducing the concepts of Stress, Strain and Young’s Modulus to describe the structural properties of building materials. This program examines the variety of bridge designs that these materials can be put to: how they work and why. It examines a bridge plan and uses concepts of Torque and Static forces to see if it stands the test of its load. Finally it challenges students to design and test their own bridges from simple materials.
