SHS1 Engineering · Semester 1 Week 8: Health and Safety in Engineering Practice

Lesson notes

Learning Objectives

Indicator: 1.1.2.LI.3 - Explain the health and safety protocols associated with basic workshop tools/machinery.

By the end of the lesson, learners can:

State at least three general health and safety protocols that apply to all workshop tools and machinery.
Explain the specific safety protocol associated with at least four basic workshop tools (e.g., bench vice, hacksaw, files, drilling machine, grinding machine).
Describe the correct sequence of actions for safely starting, using, and stopping a piece of workshop machinery.
Justify why each protocol exists by linking it to a specific accident or hazard, drawing on earlier lessons on accident causes and effects.
Demonstrate safe handling procedures when shown pictures or videos of tools and machinery, identifying any unsafe practices shown.

Exemplars (from the NaCCA curriculum)

Initiating Talk for Learning: From videos and or pictures, learners identify workshop tools and machinery. In pairs, learners discuss and share with the whole class the uses of such equipment.
Managing Talk for Learning: In a moderated discussion, learners outline their perceived health and safety protocols for each tool/machinery. Building on what others say: Individuals add to what others have said respectfully. Learners should be encouraged to tolerate others' views.
Digital Learning: Learners watch videos on health and safety protocols in the use of workshop tools/machinery and share their observations with the whole class.
