Lesson notes

Learning Objectives

Indicator: 2.3.3.LI.1 - Demonstrate knowledge of the various types of hazard controls (administrative, engineering, personal protective equipment).

By the end of the lesson, learners can:

Define the three types of hazard controls (administrative, engineering, and personal protective equipment) and explain how each works to protect workers in a manufacturing setting.
Categorise given examples of hazard controls into the correct type (administrative, engineering, or PPE) with at least 80% accuracy.
Examine a sample Material Safety Data Sheet (MSDS) and identify the key sections that provide hazard information for a common chemical.
Justify the selection of a particular hazard control method for a specific hazard found in a Ghanaian manufacturing workplace, using a simple hierarchy of controls reasoning.
Work collaboratively in mixed-ability groups to present a short analysis of hazard controls observed in a manufacturing scenario and give constructive feedback to peers.

Exemplars (from the NaCCA curriculum)

Experiential Learning: Show learners a video of a manufacturing setting and let them identify the various kinds of hazards at the setting. Let them share their observations.
Collaborative Learning: Learners in mixed-ability and gender groups research and make presentations in class on the various types of hazard control in a manufacturing process and receive feedback.
Experiential Learning: Show learners a sample MSDS of a particular common chemical and let them identify the various important information about the chemical from the material.
Talk for Learning: Learners discuss the various sections of an MSDS. Let them add to what others say and summarise their views using webbings.
Research-Based Learning: Learners in mixed-ability and gender groups research and produce an MSDS for a sample chemical substance and present their findings to the class and receive feedback.
Teaching and Learning Materials:
- * MSDS Samples * Supplementary materials
- * Internet access. * Educational field trip to a local manufacturing industry
Assessment (2.3.3.AS.1). The document marks these depth-of-knowledge levels for this indicator: Level 2 Skills of conceptual understanding; Level 3 Strategic reasoning.
