LAB CAN BE FUN! JUST BE SAFE!13
RULE #1: WALK
When going into the lab make sure to WALK. There will be no running in the lab. There will be materials and equipment out that can break if you accidently knock into them. There may be electrical wires on the ground that you may trip over as well. Please WALK and be careful.
You have been given a schedule of when our labs will be held. The day before we do a lab I will remind you so that you can come to class prepared with proper lab attire. Proper attire is as follows:
- CLOSED TOED SHOES - flip-flops, sandals, peep-toe shoes, are not allowed in the lab area. You must wear closed toed shoes on the days we have lab. If you do not have appropriate footwear on then you cannot participate in lab.
- HAIR MUST BE TIED BACK - if you have long hair it must be worn up in a ponytail on the days we have lab.
- SAFETY GOGGLES - these will be provided for you to be used in class. The goggles are located in the cabinets in the lab equipment area. Each pair of goggles is numbered to match the hooks they are on. When putting them back make sure to put them on the same hooks.
- LAB COATS - these will be provided for you to be used in class. The coats are hanging up on the hooks below the goggles cabinets. They are numbered to match the hooks they are on. When putting them back make sure to put them on the same hook.
RULE #3: HANDLING CHEMICALS
When handling chemicals during lab it is important to proceed with caution. Wear gloves whenever pouring chemicals or handling them. If there is a spill be sure to let the teacher know. If you have to dispose of chemicals, always use the waste containers provided on your lab tables. NEVER pour the chemicals back into the container you got it from. If you do, whatever was in your container could cause a chemical reaction with the chemical in the original container.
RULE #4: HANDLING EQUIPMENT
It it important that when you are using different lab equipment, you handle them with care. Microscopes should be held with both hands, one underneath and one on the arm (see microscope diagram). When handling glassware be sure to hold it with both hands when can. If something is hot, then make sure to use tongs. NEVER use your hands.
RULE #5: BROKEN GLASS
If you break a piece of glassware DO NOT TOUCH IT. Tell the teacher IMMEDIATELY when it breaks. They will then come over and properly dispose of it.
RULE #6: EYE WASH/SHOWER STATION
If chemicals or particles get in your eyes, WALK to the eye wash station and rinse out your eyes for 15 minutes. Make sure that you keep your eyes OPEN when you rinse them.
If chemicals get onto your skin, WALK to the shower station and pull on the red handle. Stand under the shower and rinse off your body for 15 minutes.
ALWAYS make sure to tell the teacher when something like this happens.
RULE #7: FIRE SAFETY
In the event that there is a fire during lab, IMMEDIATELY tell the teacher. WALK over to the fire extinguisher, pull out the safety pin, aim the nozzle towards the fire and push the handle down (I will demonstrate this for you). Empty out the entire tank.
RULE #8: NO EATING/DRINKING IN LAB
There will be NO eating or drinking during lab. There are days that we may be using chemicals and I do not want you to get sick. Also, the lab tables may have had chemicals on them previously that were not properly cleaned up so you should not eat or drink on them either.
Sometimes we will be using food as materials in lab, this too should not be eaten unless I tell you it is ok. The food may have been stored next to chemicals in the lab and could be contaminated.
RULE #9: CLEANING UP
Once lab is over, I will give you enough time to clean your lab table. If you used any chemicals make sure to dump them into the waste container at your lab table. DO NOT POUR THEM DOWN THE SINK! Once the beaker, flask, or test tube is empty then you can rinse it out in the sink at your lab table and use the brush to wash it. PLEASE ONLY TURN THE FAUCET ON DURING CLEAN UP TIME! Make sure you sponge down your lab area as well. Any materials like microscopes or petri dishes will be put back where they belong (I will direct you to where they need to be on the day of the lab).
DO NOT FORGET - safety goggles and lab coats are to be hung up on the same hooks that you got them from. The numbers on the goggles and coats should match the hooks they go on.
RULE #10: HAND WASHING
Before leaving the lab ALWAYS wash your hands. Make sure you use soap and water and scrub your hands thoroughly at the handwashing station. Some of the materials we will be using could be harmful to you, so it is important that you wash your hands so you do not get sick.
When we are in lab, it is very important that you follows these 10 rules. Lab time is supposed to be fun and as long as we all follow the rules, then no one will get hurt.
