· You are required to read it, get it signed, & return it by __________

You are responsible for following all the rules stated in the above document at all times. There is a zero tolerance policy for unsafe laboratory behavior.

Be prepared to pass a lab safety test similar to this one:

Flinn Laboratory Safety Test.

· Why do most laboratory accidents occur?

The number one reason for accidents occurring in the science lab is failure to carefully read and understand laboratory activity instructions.

Personal Safety

On lab days you are responsible for wearing close-toed shoes, tying back long hair, and using appropriate personal protective equipment such as goggles, apron, gloves, etc.

Safety Equipment in our Classroom/Lab

You should be able to identify, describe the location of, and explain the proper usage of the following list of safety items:

Eyewash station Fire Extinguisher Fire Alarm

Emergency Shower Fire Blanket Emergency Exit Plan

First Aid Kit Fume Hood Broken Glass Container

◄Corrosive Chemicals►

When a corrosive chemical comes in contact with eyes or skin, tissue damage begins immediately. While the rate and extent of this damage depends upon the chemical involved, the most important step in halting the damage is the same: The affected area must be irrigated immediately with copious amounts of water for a minimum of 15 minutes.

Eyewash Station

Emergency eyewash stations are specifically designed to provide a controlled flow of water to both eyes simultaneously. To maintain a soft, controlled flow to the eyes, regulation of the volume and pressure from the station is required. Eyewash stations require an uninterrupted, 15-minute supply of water.

Emergency Shower

Emergency showers are designed to provide a deluge large enough to encompass the whole body. Emergency showers should be selected when large volumes of potentially injurious materials are present, i.e., chemical storage areas. Emergency showers are not to be considered or used for irrigating chemicals from the face and eyes, due to the delicate nature of these tissues and the potentially high velocity and volume of water an emergency shower may produce.

Fire Safety

· Fire Extinguisher-located in the prep area of the laboratory

More info here

· Fire Blanket- located in the prep area of the laboratory

Remember “Stop, Drop and Roll” if you are on fire. If you are assisting, cover the person as completely as possible in the fire blanket to smother the flames.

· Fire Alarm-located in the hallway near the outside exit doors

· Emergency Exit Plan- exit plan posted next to both classroom doors

· FUME Hood

Hoods are used whenever any volatile or toxic chemical is handled. The glass window can be adjusted to stay open at several levels. Leave enough room for your hands to fit into the hood and do your work comfortably BUT make sure that the glass window covers your eyes and nose. The fume hood fan should always be turned in the ON position before the chemical bottle is opened. NEVER remove anything containing fuming chemicals from the hood

Broken Glass Container- located on the counter at near lab station #4; Never pick up broken glass with your hands, use a broom & dust pan; Never place broken glass in the trash can, always use the cardboard box.

First Aid Kit-located on top of the goggles cabinet. Use only for minor first aid needs. See the nurse for further attention.

You need to be able to recognize the Lab Safety Symbols

Material Safety Data Sheets

Material Safety Data Sheets contain information regarding the proper procedures for handling, storing, and disposing of chemical substances.

Federal and state laws require you to have Material Safety Data Sheets (MSDS) for every chemical at the location in school where chemicals are stored.
