Science Safety Test Outline

The test outline is as follows:

1. Identify the problems and solutions in the image

2. Know what WHMIS means and the names of its symbols

3. Know what HHPS means and the names of its symbols

Know precautions for HHPS products

4. Study the names of the science equipment in the package and their uses and how to use them safely

Science Equipment List Answers

Name	How it is used	Safety Procedures
Beaker	-mixing liquids -containing liquids -Heating substances -Measuring liquids	Use tongs or gloves if it is hot; careful not to spill; be careful because it’s fragile
Hot Plate	For heating substances	Wear safety goggles, gloves; takes a while to cool down; tie hair back, use tongs
Graduated cylinder	Measuring liquids, powders. Mix substances. Very accurate measuring.	Can be fragile. Can easily tip over, be careful. No hot substances in plastic.
Test tube	Combining substances; heating; observing.	Fragile, does not stand on its own. Use a stand.
Funnel	Pouring liquids into small containers	Pour slowly to avoid spills
Beaker Tongs	Picking up hot beakers	Pick beaker up securely in the middle. Move slowly to avoid spills.
Microscope	Viewing microscopic specimens	They are expensive and fragile; be careful.
