Lets talk about LAB SAFETY in the Chemistry

Let’s talk about… LAB SAFETY in the Chemistry Classroom

Before continuing with this lesson, you should have already read the FLINN Safety Rules and Contract! It’s posted in Google Classroom.

Know the locations and operating procedures of all safety equipment including the first aid kit, eyewash station, safety shower, fire extinguisher, and fire blanket. Know where the fire alarm and the exits are located. We will review this once you are back in the classroom

Any time chemicals, heat, or glassware used, students will wear laboratory goggles. There will be no exceptions to this rule!

• Dress properly during a lab activity. Long hair, dangling jewelry, and loose or baggy clothing are a hazard in the lab. Long hair must be tied back and dangling jewelry and loose or baggy clothing must be secure. • Report any accident (spill, breakage, etc. ) or injury (cut, burn, etc. ) to the instructor immediately, no matter how trivial it may appear.

When Using Chemicals… • Check the label on chemical bottles twice before removing any of the contents. Take only as much chemical as you need. • Never return unused chemicals to their original containers. • Examine glassware before each use. Never use chipped or cracked glassware. Never use dirty glassware.

When Using Chemicals… • Always work in a well-ventilated area. • Use the fume hood when working with volatile substances or poisonous vapors. Never place your head into the fume hood.

When Using Chemicals… Always Add Acid to Water! Why? ? ? So much heat is released that the solution may boil very violently, splashing concentrated acid out of the container! If you add acid to water, the solution that forms is very dilute and the small amount of heat released is not enough to vaporize and spatter it. I always remember this by A&W root beer!

When Using Chemicals… • Dispose of all chemical waste properly. Your teacher will tell you what the proper disposal method is for all lab waste. • Know what to do if there is a fire drill during a laboratory periodcontainers must be closed, gas valves turned off, fume hoods turned off, and any electrical equipment turned off.

When Using Chemicals… If a chemical should splash in your eye(s) or on your skin, immediately flush with running water from the eyewash station or safety shower for at least 20 minutes. Notify your teacher immediately!

Other Safety Concerns… • Never handle broken glass with your bare hands. Always notify your teacher before attempting to clean up any glass breakage! Use a brush and dustpan to clean up broken glass. Place broken or waste glassware in the designated glass disposal container.

Other Safety Concerns… Exercise extreme caution when using a gas burner. Take care that hair, clothing and hands are a safe distance from the flame at all times. Never put any substance into the flame unless specifically instructed to do so. Never reach over an exposed flame. Light gas burners only as instructed by the teacher.

Bunsen Burner 101 How do I light a Bunsen Burner? ALWAYS light your match (we will use multi-purpose lighters in this class) BEFORE turning on the gas to your Bunsen burner.

Bunsen Burner 101 • Never leave a lit burner unattended. Never leave anything that is being heated or is visibly reacting unattended. Always turn burner or hot plate off when not in use. • You will be instructed in the proper method of heating and boiling liquids in test tubes. Never point the open end of a test tube being heated at yourself or anyone else.

What should you do if your clothes catch on fire? NEVER RUN!

In Chemistry, LAB SAFETY is EVERYTHING. You are expected to follow these rules at all times.
