Lab Safety

LABORATORY EQUIPMENT AND THEIR FUNCTIONS

BEAKER USED TO HOLD OR MIX CHEMICALS SAFETY: FRAGILE. DO NOT RUN UNDER WATER WHEN IT IS WARMED. IT MIGHT BREAK! SAFETY: HOLD BEAKER CAREFULLY WHILE TRANSPORTING IT

GRADUATED CYLINDER MEASURES VOLUME OF LIQUIDS ACCURATELY SAFETY: DO NOT LEAVE LIQUID IN THEM WHEN NOT IN USE

RING STAND MOSTLY USED AS A SUPPORT SAFETY: DO NOT ALLOW IT TO BECOME TOP HEAVY. SAFETY: IT MAY GET HOT WHEN HEATED

PIPETTE USED FOR MOVING SMALL AMOUNTS OF LIQUID SAFETY: NEVER USE AS EYE DROPS

TRIPLE BEAM BALANCE MEASURES MASS IN GRAMS SAFETY: ALWAYS SUPPORT THE ENTIRE WEIGHT OF THE BEAM AND NEVER CARRY IT BY THE ARM

ELECTRONIC MASS RECORDER MEASURES MASS IN GRAMS SAFETY: ALWAYS SUPPORT THE ENTIRE WEIGHT OF THE BEAM. SAFETY: WATCH OUT FOR POWER CORDS

STIRRING ROD GLASS ROD USED FOR STIRRING SAFETY: BE CAREFUL! They break easily

ERLENMEYER FLASK HOLD AND MIX LIQUIDS SAFETY: FRAGILE. DO NOT RUN UNDER WATER WHEN WARMED. IT MAY BREAK!

THERMOMETER USED TO TAKE TEMPERATURE READINGS SAFETY: PLEASE REPORT ANY BROKEN THERMOMETERS IMMEDIATELY.

TEST TUBE USED TO MIX AND HOLD CHEMICALS SAFETY: FRAGILE. DO NOT RUN UNDER WATER WHEN WARMED. IT MAY BREAK!

MICROSCOPE USED TO SEE VERY SMALL THINGS SAFETY: THESE ARE EXPENSIVE! DO NOT DO ANYTHING THAT MAY BREAK THEM CARRY WITH TWO HANDS BY THE BASE, NOT THE NECK. DO NOT PLAY WITH THE KNOBS UNLESS INSTRUCTED TO DO SO.
