Course Outline / Evaluation, Map of Room 110, Safety Equipment

Review :

Objectives : students should be able to :

1.1 list the safety and protective equipment available in the laboratory

1.2 describe how and when to use each piece of equipment

1.3 indicate on a school map the location of the nearest fire alarm and appropriate fire exits

1.4 list sources of first-aid assistance other than the classroom teacher

1.5 describe common chemistry laboratory hazards

1.6 describe the appropriate procedure or technique for dealing with particular hazards

1.7 produce a list of general rules of safe laboratory conduct

1.8 display a conscious safety attitude in the laboratory

 

Part I - Laboratory Safety - Introduction and Notes :

Have students spot the hazards on overhead sheet, page 1-1, and discuss the proper techniques that should be used.

Demo - get out safety equipment in lab, explain and discuss proper use

• safety glasses = shower
• aprons = 1st aid kit
• fire extinguisher = fire blanket
• eye wash

Map - hand out and label map of room 110, and outer hallways, with the following

• fire alarm
• fire exits
• name of 1st aid attendants
• fire extinguisher
• shower
• fire blanket
• eye wash

Lab Hazards

• students divide into groups and each group researches the following lab hazards page 747 of Nelson and presents to the class

a) glass safety and cuts d) fire safety

b) bums e) electrical safety

c) eye safety f) chemical spills

Make any additions necessary (use pages 1-2 to 1-4 as a guide) as students present their notes to the class.

Safety Rules

• students divide into different groups and each group devises a set of safety rules that should be followed in the lab
• go over as a large group, record on board, discuss, make additions of missed rules (see page 749 of Nelson, and page 1-5 of notes)
• students copy final version into notebooks
