How could you apply the safety rules for performing an experiment in a chemistry laboratory?

Answer 1

Well there are many things. In the chemistry labs that I have had, they stress the importance of knowing where everything is in the room. Make sure you are aware of where the eye wash station is (if you have one), the safety shower, fire blanket or fire extinguisher, and first aid kit. Make sure and wear your goggles when doing any experiments. Stuff can splash up in your eye and that isn't much fun. Be careful with Bunsen Burners. Don't wear baggy clothes because they can get snagged or catch on fire! Follow procedures! Do something stupid and you can put yourself and your lab partners in trouble! It is also fun to play with sulfuric acid. Put some on your skin, it feels awesome!

Lab behavior

· Be prepared for your work in the laboratory. Horseplay, practical jokes, and pranks are dangerous, and not tolerated at any time.

· Follow all written and verbal instructions carefully. If you do not understand something, ask the instructor before proceeding. Do not touch any equipment, chemicals, or other materials unless instructed to do so.

· No student may work in the laboratory without an instructor present.

· Do not eat, drink, or chew gum in the laboratory. Do not use laboratory glassware as containers for food or beverages. Do not apply cosmetics.

· Perform only those experiments authorized by your instructor.

· Keep the aisles near the lab tables clear. Push the chairs away from the lab tables.

Safety material knowledge

· Know the locations and operating procedures of all safety equipment including the eyewash station, safety shower, fire extinguishers, and fire blankets. Know where the fire alarm and exits are located.

· Dispose of all chemical waste properly. Solid metals, matches, filter paper, and other insoluble materials are to be disposed of in the clay crocks provided. Your teacher will tell you how to dispose of the soluble waste.

· Set up and use the apparatus as described in the lab manual or by your teacher. Never use makeshift arrangements.

· Students are never permitted in the science storage rooms or preparation areas. Exception: in room 116, the safety shower/eyewash is located just inside the door of the storage room. Students on fire or with chemicals on them are allowed to use the safety equipment in this case.

Personal Safety

· When using sharp instruments, always carry with tips pointing down and away. Always cut away from your body. Never try to catch falling sharp instruments. Grasp sharp instruments only by the handles.

· Safety goggles and a lab apron should be worn at all times. Students wearing contact lenses should be especially careful of this rule since chemicals can become trapped between the contact lens and their eye.

· Long hair should be tied back or covered, especially in the vicinity of an open flame.

· Jewelry that might present a safety hazard such as dangling necklaces, chains, medallions, or bracelets, should not be worn in the lab. Put your jewelry in your book bag rather than on the lab table so that it does not become soiled or lost.

· Shoes must completely cover the foot. No flip-flops or sandals will be allowed.

· Report any accident (spill, breakage) or injury to the instructor immediately.

· If a chemical should splash in your eye or on your skin, immediately flush with running water from an eyewash station or safety shower for at least 15 minutes. Notify the instructor immediately.

· All chemicals in the laboratory are considered dangerous. Do not touch, taste, or smell any chemicals unless specifically instructed to do so. The proper technique for smelling chemical fumes is to wave your hand across the opening in a wafting motion. Sniff the fumes gently, rather than taking deep breaths.

Common sense

· Check the label on the chemical bottles twice before removing any of the contents. Never return unused chemicals to their original container.

· Never use mouth suction for liquids. Always use a pipette pump or rubber bulb.

Not so common sense

· Always do what you oughter and add acid to water. Swirl the solution carefully since the mixing of acid and water produces heat.

· Never use flammable liquids near an open flame or source of heat. Always use a hot water bath when heating a flammable liquid.

glass safety

· Never handle broken glass with your bare hands. Use a brush and dustpan to clean up broken glass. Dispose of broken glass in the designated container.

· Always lubricate a piece of glassware (tubing, thermometers, etc.) with water or glycerine before attempting to insert it in a stopper. Protect your hands with a towel.

· Never apply force when inserting or removing glassware from a stopper. Use a twisting motion. If a piece of glassware becomes "frozen" in a stopper, take it to your instructor.

· Do not place hot glassware directly on the lab table. Always use an insulating pad.

· Allow plenty of time for hot glass to cool before touching it. Hot glass looks like cool glass. Determine if an object is hot by bringing the back of your hand near it.

· Hot glassware may shatter if it is immersed in cold water. Examine glassware before each use. Chipped or cracked glassware can shatter when heated. If glassware is dirty, clean it before use.

Fire safety

· Exercise extreme caution when using a gas burner. Keep your hair and clothing away from the flame. Never leave a lit burner unattended. Never leave reacting chemicals unattended. Always turn off the burner or hot plate when not in use.

· Never heat a closed container. Never look into a container being heated.
