UNIT 1: SAFETY

Safety Symbols Scientists use symbols as a short way of communicating danger. Pay attention to the safety symbols during labs.

Animal Safety Be careful; animals can bite and scratch, especially wild ones. Treat all animals (alive and dead) with respect.

Breakage This symbol indicates the possibility of breaking glass. You should wear goggles at all times. Broken glassware goes in the glass bin.

Disposal Chemicals and other materials should be disposed of properly. Read lab and/or label for proper disposal.

Electric Shock The item has electric power and can deliver a dangerous shock. Have dry hands and unplug properly. Keep away from water.

Flames Material is flammable. Stay away from flames.

Fumes Material emits dangerous fumes. Use this material in a fume hood. Make sure the room is properly ventilated.

General Safety Awareness Indicates that general lab safety and common sense need to be used.

Hand Washing Wash hands thoroughly after using this material.

Heating Use tongs or test tube holders while heating. Be aware that the substance is hot and should not be handled with bare hands. Goggles should be worn at all times.

Heat-Resistant Gloves Use heat-resistant gloves when handling hot items. Take care when transporting hot items in the lab.

Lab Apron A rubberized lab apron needs to worn while working with this substance.

Physical Safety The activity involves physical activity. Follow instructions and alert the teacher if you should not participate.

Plant Safety Handle plants as directed. Many plants are toxic or have thorns. DO NOT INGEST plant material.

Poison Materials may be toxic. Do not let toxic materials get on your skin. Do not inhale or eat the substance. Wash hands when finished.

Safety Goggles Wear safety goggles when using chemicals, heat, or glassware.

Sharp Object The activity has sharp items that can cut or pierce the skin. Cut away from yourself and others.

What happens if you don’t follow safety procedures? The worst thing that can happen is that you will be responsible for injuring yourself or your classmate. But that’s not all…

What happens if you don’t follow safety procedures? You will be removed from lab and given a very boring writing assignment to replace it. It is possible to be permanently removed from lab. Not a fun thing.

Material Safety Data Sheet MSDS Material Safety Data Sheet

MSDS Sheets MSDS sheets exist for every chemical that you may use in a work area. McDonald’s even has them. They provide information on how to handle, store, clean up, and treat for exposure.

Sheet Set-up MSDS sheets are divided into 16 sections, each dealing with a certain safety concern. For our purposes, we will focus on sections 1-8, 10 and 11.

Section 1 The name of the chemical and the company it came from are found here. Company contact information is listed. (Use your sample sheet to complete your notes.)

Section 2- Composition This explains what makes up the substance, usually in chemical terms. It may also give a common everyday use name. (What is the common name for this substance?)

Section 3 - Hazards This section provides descriptions of the chemical. (why?) It also warns of any toxicity, including fatal dosage. It also notifies the user if the chemical is flammable or combustible. In addition, it has quick info:

Section 3 - Hazards Info at a glance: (complete in your notes) Health- ___ Flammability- ___ Reactivity - ____ Exposure - ____ Storage - ____ Scale: 0 = low hazard, 3 = high hazard *The higher the numbers, the nastier the chemical*

Section 4 – First Aid (This part is really important in lab.) This section provides information on how to treat a person that has been exposed to the chemical. It is possible that emergency medical workers will need this section – its our job to provide it. (How do you treat someone who has swallowed this chemical?)

Section 5 – Fire Fighting Not all chemical fires can be put out with water – many chemicals react with water and could make the fire worse. (Is it ok to use water on this chemical?)

Section 6 – Accidental Release Accidental release means that the chemical has escaped from the controlled area of the lab; the general population is being exposed. (What should you do if this chemical is accidentally released?)

Section 7 – Handling and Storage Many chemicals are safe unless stored incorrectly. Improper storage can lead to accidental mixtures, fume build up, and unstable chemicals. (How important is it for this chemical to be stored properly?)

Section 8 – Personal Protection If you must handle this chemical, read and follow the information in this section before touching the chemical. (What safety equipment should be worn while handling this chemical?)

Section 10 – Stability/Reactivity Two chemicals can be safe by themselves but harmful if you mix them. This section provides info on what to avoid.

Section 11 – Toxicological Info This is where you find out the physical effects of exposure. It lists the effects as well as the targeted organs. (What organ is targeted by this chemical?)

MSDS Information Your work place should have MSDS sheets for all chemicals used/stored in the building. You should know where they are. You can also use the internet to find up-to-date MSDS sheets. I suggest Flinn Scientific.
