About This Chapter
Praxis Biology: Laboratory Safety - Chapter Summary
This chapter on laboratory safety is designed to help you prepare for relevant questions on the Praxis Biology examination. The video lessons allow you to review laboratory safety practices such as the use of goggles, laboratory coats, gloves and protective footwear. You'll also explore the mission of the Occupational Safety and Health Administration (OSHA) along with techniques for maintaining safety in the workplace. The information in this chapter could help you with:
- Discussing the basic rules of laboratory safety
- Identifying and properly using safety equipment
- Properly safeguarding the body while in the laboratory
- Understanding safe chemical storage procedures
- Learning more about OSHA and describing the responsibilities of employers with regard to workplace safety
- Discussing the safe use, handling and disposal of biological specimens and hazardous materials
- Listing the components of Safety Data Sheets
Develop your expertise in these areas by watching the online videos in this chapter, which are delivered by professional educators and industry experts. With pause, play and rewind features, the animated videos are short and concise. Use your mobile device to watch the videos or to listen to their narration anytime it's convenient. You could also check out the written transcripts and print out the worksheets for use as additional study resources. Submit your questions on laboratory safety for personalized support.
Praxis Biology: Laboratory Safety - Chapter Objectives
Your ability to observe laboratory safety measures will be evaluated during the first of six content categories, Nature of Science: Scientific Inquiry, Methodology, Techniques and History. The category accounts for 14% of the Praxis Biology examination, and it includes about 21 questions. As you answer questions in this category, you'll display your ability to adhere to emergency procedures, and effectively utilize laboratory and safety equipment. You'll also demonstrate your understanding of the protocols for safely handling biological specimens and acid solutions. This is a 2.5 hour computer-delivered examination that includes 150 selected-response questions.
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
