Transcript of Safety in the Science Classroom

Safety in the Science Classroom
Guidelines Eye Protection

Wear safety goggles at all times when working in the lab

Know where the eyewash station is located and how to use it
Wear only closed toed shoes in the lab
Tie back long hair
Secure loose clothing and remove jewelery Clothing Protection Wear latex or nitrile gloves to protect yourself from chemicals in the lab

Allow equipment to cool before handling it and storing it

Hand Safety Never leave a hot plate unattented while it is turned on

If your clothing catches on fire, walk to the emergency lab shower, and use the shower to put out the fire

Allow all equipment to cool before storing Heating Safety Do not eat or drink anything in the lab. Never taste chemicals

If a chemical gets on your skin, clothing or in your eyes, rinse it immediately with lukewarm water and alert your teacher.

If a chemical is spilled, alert your teacher. Do not clean it up yourself unless your teacher says it is OK to do so.

Dispose of chemicals as instructed. Do not dump chemicals in the sink! Chemical Safety Handle animals only as directed by your teacher

Always treat animals carefully and with respect

Wash your hands thoroughly after handling any animal Animal Safety Safety Quiz Safety Plan for a Typical Science Classroom Keep shelves organized. Lable everything clearly.

Do not leave bottles of chemicals unused on the shelves of the lab for more than one week or unused in the stockroom for more than one year.

Dispose of or use up any leftover chemicals

Order diluted substances versus concentrated substances to reduce risks.

Have separate containers for trash, broken glass, and for different categories of hazardous chemical wastes. Chemical Storage Students will be expected to remain in their seats until instructed to approach the lab area.

Students will work in pairs during labs. Horseplay will not be tolerated.

Students will only approach storage closet for suppplies when instructed.

Students will know the location of all emergency exits, the fire extinquisher, eyewash station, and emergency shower. Projected Student Traffic All living organisms will be sheltered in a safe and appropriate environment, away from the laboratory.

Plans will be made for caring of animals during school vacations

The teacher and students will become knowledgeable about appropriate care for the species living in the science classroom.

The teacher will follow all national, state, and local reguations regarding the care of animals in the science classroom. Placement of Living Organisms The classroom will have at least one fire extinguisher, eyewash station, emergency shower, and fire blanket.

All items will be located near the laboratory for easy access.

Students will know the location of each item and how to use the items properly

Students will know proper procedures should an emergency arise. In Case of Emergency Safety Contract Ethical and Humane Treatment of Living Organisms When experimenting with fruit flies, take care in quieting and/or killing them by using one of the following methods:

1. Place the fruit flies in a Petri dish, gently covering them with cotton, and then inverting the dish for examination under the microscope.

2. Refrigerate culture jars and place "chilled" flies on a Petri dish over ice.

3. Anesthetizing kits may also be used, such as FlyNap kits. Invertebrates Do not take vertebrates from the natural environment

Obtain animals from a certified disease-free source

When studying developing chicken embryos, do not use embryos that are more than 18 days old.

Dispose of dead embryos, which may carry pathogenic bacteria.

Do not give away or sell any animals

Do not release animals that are not indigenous to the area into the enviornment
Vertebrates Keep laboratory animals isolated from wild animals
Take care to avoid contact between humans and animals when either of them may be a disease carrier
Only the student assigned responsibility for animal care should have direct contact with the animals
Maintain a good environment for the animals, with ample food and water available to them at all times, including weekends and holidays. Keep cages clean of wastes.
Protect animals during times of pesticide use
Sterilize cages and equipment before and after use. Other Guidelines Venemous reptiles and fish

Black widow and brown recluse spiders


Bees, wasps, hornets and other stinging insects
Animals Prohibited in the Classroom Students will have knowledge of endangered and protected species in the field study area.

Students will not be permitted to remove any vertebrates from their habitat

All specimen collections will be legal and serve valid educational purposes Field Studies Chemical Safety Plan Common Chemicals for the Classroom Behavior Management of Students in a Science Classroom Students will not conduct any experiments with chemicals unless the teacher is in the room

Students will dispose of chemicals in the proper resceptables as instructed by their teacher

Students will not run with chemicals. Horseplay and pranks wil not be tolerated in the lab.

Students will not enter chemical storage area unless instructed by the teacher

Students will assume all chemicals are poisonous and be careful while working in the lab
Handling of Chemicals Students will carry microscopes with one hand on the arm and the other hand on the base.

Students will clean all equipment when finished and place equipment in the proper storage area.

Students will not leave bunsen burners unattended when lit.

Students will not touch any lab equipment when the teacher is not in the room. Handling of Lab Equipment Students will act appropriately and maturely while in the lab.

Students will not conduct any experiments or handle any equipment without the presence of a teacher.

Students will not leave a lit bunsen burner unattended.

Students will walk, not run in the lab.

Horseplay and pranks will not be tolerated
Proper Behavior in the Lab Students will treat all organisms with respect.

Students will understand and follow safety precautions when working with live organisms

Students will wash hands after handling both living and non-living organisms

Students will conduct dissection activities in a clean and organized work space with care

Students will wear appropriate attire such as gloves, apron, and goggles when working with organisms

Working with Living and Non-Living Organisms Students will have knowledge of the location and proper use of all safety equipment

Students will not activate emergency shower unless there is an emergency in the lab
Handling of Safety Equipment If students do not have appropriately and maturely in the lab, the following consequences will occur:

For a first offense, the student will receive a verbal warning

For a second offense, the parent will be called. The teacher, student, and parent will have a conference where they will go over the safety contract together reaffirming their understanding of the safety guidelines in place.'

For a third offense, the student will receive a written referral. Consequences for Behavior Sucrose: http://avogadro.chem.iastate.edu/MSDS/sucrose.htm

Do not leave bottles of chemicals unused on the shelves of the lab for more than one week or unused in the stockroom for more than one year.
Do not over buy chemicals - only buy enough to last one school year
Reduce risks by ordering diluted instead of concentrated substances
Store chemicals by the hazard class indicated on the MSDS.
An inventory of chemicals should be completed at least once a year
Label storage areas with appropriate signs
Date containers upon receipt and when opened
Store all chemicals at eye level and below
Chemical Storage Consult MSDS for proper disposal procedures for individual chemicals

Dispose of or use up any leftover chemicals after on year.

Have separate containers for different categories of hazardous chemical waste.

Ensure students understand before an experiment the directions for disposing of any chemicals involved in the experiment.

Never return dispensed chemicals to stock solution
