KEEP GLASSWARE AT LEAST a hands length from the edge NEVER take a big whiff of a substance to smell it . NEVER POUR water into a concentrated acid. Acid should be poured slowly into water.

ALWAYS POINT the top ends of test tubes ALWAYS POINT the top ends of test tubes that are being heated AWAY from people. MOVE TEST TUBES slowly over the flame to distribute the heat evenly. ONLY DRY GLASSWARE should be heated. NO HOT GLASSWARE IN WATER. Rapid cooling may make it shatter. HANDLE HOT OBJECTS with tongs and/or protective gloves NEVER REACH across an open flame or burner.

Let BURNERS AND HOTPLATES COOL down before touching them Let BURNERS AND HOTPLATES COOL down before touching them. Test to see if they are cool enough by bringing the back of your hand close to them.

Ringstands -safe and convenient way to perform reactions that require heating using a Bunsen burner.

Ringstands Components Iron Rings -connect to a ringstand and provide a stable, elevated platform for the reaction.

Ringstands and their Components Wire Gauze -sits on the iron ring to provide a place to stand a beaker.

Ringstands and their Components Utility Clamps - used to secure test tubes, distillation columns, and burets to the ringstand.

Bunsen Burner -used for the heating of nonvolatile liquids and solids.

Strikers -used to light Bunsen burners. The flints on strikers are expensive. Do not operate the striker repeatedly just to see the sparks!

Wash Bottle -has a spout that delivers a wash solution to a specific area. Distilled water is the only liquid that should be used in a wash bottle.

Beaker Tongs -are used to move beakers containing hot liquids

Evaporating Dish -used for the heating of stable solid compounds and elements.

Crucible - used for heating certain solids, particularly metals, to very high temperatures.

Safety Symbols Eye Protection Sharp Objects Electrical Safety Wear safety goggles when working with chemicals, flames, or heating devices. If a chemical gets in your eye, flush in water for 15 minutes and notify the teacher. Sharp Objects When using knifes or other sharp objects always walk with the points facing down.
