About This Chapter
Equipment, Safety Procedures and Hazards in the Chemistry Lab - Chapter Summary and Learning Objectives
Chemicals are ubiquitous in our environment. Whether it is cleaning in the home, or performing a laboratory experiment in school, working with chemicals is an every day affair. In fact, working with chemicals is so commonplace that most of us are barely aware of all the instances in our lives where we find ourselves in contact with them. Yet chemicals are very powerful substances and while they have the potential to do much good, they demand to be treated with respect and with caution. In this chapter, we will examine the equipment commonly found in the chemistry lab. We will review safety procedures for working around chemicals and related equipment. You will come to appreciate some of the special ways of handling chemicals and other potential hazards, so that you can use these materials with safety and confidence. These lessons will cover topics such as:
- Preparing and handling laboratory solutions, chemicals, and biological materials
- Methods for safely storing chemicals
- Health and safety regulations
- Disposing of hazardous materials

1. Common Laboratory Equipment: Types & Uses
Biologists use all kinds of equipment in their labs to run their experiments. In this lesson, you'll identify some of the most common pieces of equipment as well as when you should or shouldn't use them.
2. Chemistry Lab Equipment: Supplies, Glassware & More
When you bake a cake, you use different tools for each step in the process: a bowl for mixing, cups for measuring ingredients and an oven for baking. In this lesson, you will discover the name and purpose of many of the different tools that are used in the chemistry lab.
3. Handling Laboratory Solutions, Chemicals & Biological Materials
Working in a laboratory requires careful attention, both for safety and successful completion of tasks. Learn about the many ways biological and chemical substances need to be properly prepared, identified, stored, dispensed, and disposed of.
4. How to Preserve, Stain & Mount Microscope Specimens
Microscopes are incredible tools for observing the tiniest of organisms. Here we will identify the types of slides that can be made and describe how to best preserve, stain, and mount specimens. At the end, you can test yourself with a brief quiz.
5. Material Safety Data Sheet (MSDS): Definition & Purpose
In this lesson, you'll learn what a material safety data sheet is, its purpose, what information it contains, and the things you should focus on as a worker.
6. Chemical Hygiene Plan (CHP): Definition & Use
In this lesson, we will discuss how to create and apply information from a chemical hygiene plans (CHP) to keep workers safe in a lab containing hazardous materials.
7. Understanding Laboratory Measurements: Units & Types
There are many different units that can be used for measurements. This may not only lead to incorrect data measurements, but also to confusion about which units are most appropriate. Therefore, a standard set of units is used for each type of measurement in the biology lab.
8. The Metric System: Units and Conversion
Just like you and your friend communicate using the same language, scientists all over the world need to use the same language when reporting the measurements they make. This language is called the metric system. In this lesson we will cover the metric units for length, mass, volume, density and temperature, and also discuss how to convert among them.
9. Laboratory Safety Techniques: Protecting People and Equipment
Laboratory safety is not fun, but following the rules ensures that lab activities can be enjoyed by everyone. In this lesson, we cover some basic lab safety rules to follow that will help lab time be both safe and fun.
10. Standard Laboratory Safety Equipment
Even with proper precautions, lab accidents do happen. When they do, knowing what safety equipment is in your lab, where it is located, and how to use it can prevent further harm to both the lab and the people working in it.
11. Personal Safety Equipment for the Science Lab
Science labs are great places to explore and learn. But they're only as safe as the people who use them, so in this lesson, we'll discuss some of the ways that you can protect yourself and prevent personal harm in the event of a lab accident.
12. Safe Chemical Storage, Use & Disposal
An important part of lab safety involves the correct usage, storage, and disposal of chemicals. Lab safety is everyone's responsibility, so it's important that you know the proper procedures and protocols for using chemicals in the lab.
13. Working with Biological Specimens Safely in the Lab
Working with biological specimens can be interesting and rewarding. But we need to be careful when handling and disposing of these types of specimens because they do have the potential to do harm both in and out of the lab.
14. Health and Safety Regulations: OSHA
The workplace can be a dangerous place, and workers are injured and even killed on the job. In this lesson, you'll learn how the Occupational Safety and Health Administration works to minimize dangerous workplace conditions.
15. Understanding SDS/OSHA Labels on Chemicals & Supplies
Safety Data Sheets are an important component of safe lab work. In this lesson, we'll dissect an SDS to better understand its various components and see how they help keep you and everyone else safe in any lab setting.
16. Disposing of Hazardous Materials: Public Safety & Controversy
Hazardous materials come in all types and from many sources. Because they may be harmful to human health, it's important to dispose of them properly and safely. It's also due to this potential harm that both their use and disposal are controversial.
