Protocols/Scenarios

PASS –Pull the Pin –Aim the Hose –Squeeze the Handle –Sweep Side to Side

Acid Safety Always add acid to water. A comes before W, so Acid is added to Water Pour slowly and do not splatter

Eye Safety Goggles must be worn at ALL times in the lab. If goggles are not worn, you will receive a zero on that lab. Eye Demo, Contact Demo, Goggles

Dress Safety No dangling jewelry. Necklaces, bracelets, watches, puffy sleeved shirts, and ID’s that dangle may get caught on glassware, fall into chemicals, or swing into the flame. Long Hair – Long hair should be tied back at all times when in the lab.

No open toed shoes. This is to prevent broken glass, chemicals, and other harmful materials from getting on your feet. Pants are good for protecting your legs. Don’t wear clothing that you would hate to have get dirty. The best prevention is to not wear “nice” clothes on days you know you will be in lab.

Safety Equipment Fire Extinguishers- –A – Combustibles (Paper, wood) –B – Liquids (Gasoline, Kerosene) –C – Electrical –D – Metal (Magnesium, Zinc) –Most schools have ABC fire extinguishers. When working with metals we will have a D class fire extinguisher present in the room

Chemical Spill – In the case of acids or bases being spilt on the floor or lab bench, notify the teacher immediately, and get it cleaned up. This way it is not being tracked around in the room, and someone doesn’t accidentally get it on them. –Sand – Used to extinguish metal fires. –Baking Soda – Used to neutralize an acid spill –Kitty Litter – Used to soak up and contain a liquid spill.

Student Use of the Laboratory No Unauthorized experiments. No eating or drinking in the lab. Chemicals can get into food and drink easily and without your immediate knowledge. Do not drink from lab equipment. You don’t know what other people have put into the lab equipment that you are drinking from.

Do not test the odor of a chemical directly. In order to prevent this, wafting is the procedure we use. Remember, hot glassware looks the same as cold glassware so always check it before grabbing hold of it. Always point test tubes away from yourself and others so that chemicals will not splatter out onto you, or others.

NO HORSEPLAY!!! Horseplay in the lab is not allowed. Your group must clean their lab area completely, and leave everything organized. Leave the lab in an orderly manner with no pushing or shoving.

Before Lab Always READ the experiment beforehand. Sometimes a quiz will be given over the lab. Sometimes there will be questions to answer before being allowed to go to lab.
