LAB SAFETY VIDEO





LAB EQUIPMENT TERMS & USES

 P A S S 
Pull the Pin at the top of the extinguisher. The pin releases a locking mechanism and will allow you to discharge the extinguisher.  

Aim at the base of the fire, not the flames. This is important - in order to put out the fire, you must extinguish the fuel. 

Squeeze the lever slowly. This will release the extinguishing agent in the extinguisher. If the handle is released, the discharge will stop.

Sweep from side to side. Using a sweeping motion, move the fire extinguisher back and forth until the fire is completely out. Operate the extinguisher from a safe distance, several feet away, and then move towards the fire once it starts to diminish. Be sure to read the instructions on your fire extinguisher - different fire extinguishers recommend operating them from different distances. 

Remember: Aim at the base of the fire, not at the flames!!!! 

 How To Use a Fire Extinguisher 

PASS = Pull, Aim, Squeeze & Sweep with a Fire Extinguisher

It's easy to remember how to use a fire extinguisher if you can remember the acronym PASS, which stands for Pull, Aim,Squeeze, and Sweep. 

	Pull the pin. This will allow you to discharge the extinguisher.
	Aim at the base of the fire. If you aim at the flames (which is frequently the temptation), the extinguishing agent will fly right through and do no good. You want to hit the fuel.
	Squeeze the top handle or lever.  This depresses a button that releases the pressurized extinguishing agent in the extinguisher.
	Sweep from side to side  until the fire is completely out. Start using the extinguisher from a safe distance away, then move forward. Once the fire is out, keep an eye on the area in case it re-ignites.

LAB SAFETY VIOLATIONS - STORY

LABORATORY SAFETY RULES   

  

• Read the following story; 
• on notebook paper list all lab safety violations, number each one.  
• highlight on this handout the broken safety violations.
• DUE:  9/10/2013, TUESDAY

The bell rang, students sat in their seats, and they began to write down their homework.  Ryan eagerly asked Mrs. Remis, “What are we doing today?”  Mrs. Remis impatiently said, “As always Ryan grab your chair, check on the white board and let me get us all started.”  Ryan responded, “Oh yeah, there it is, we have a Chemistry lab.”  Mrs. Remis gave the class a brief overview of what they would be doing during the lab and she stressed to the class, “Please be sure to follow appropriate lab safety procedures.”   

Ryan and John sprinted to a lab station, yelling, “We got this station!” Once at the station, Ryan asked John if he read the lab last night for homework to which John replied, “Nope, did you?”  Ryan responded to John’s question by saying, “Are you serious, I never read anything for this class.” They both looked at each other and decided to just start the lab. “Ryan, you go get the chemicals and I’ll light up the Bunsen burner,” said John. Even though all of their classmates went to the safety goggle cabinet prior to starting the lab, Ryan and John decided not to go.  John said in a smug way, “Forget the goggles; we are too cool to wear those things.”  Ryan walked up to the front lab bench where the chemicals were, removed the lids, picked up the flasks, and started to smell the different chemicals. “I am just going to bring back the ones that smell the best,” said Ryan. Little did Ryan know that one of the chemicals was sulfuric acid, and after taking a deep breath, he thought that his nose hairs were on fire.   “Hey Ryan, you didn’t even put the lid back on,” yelled Mrs. Remis.  Ryan ignored Mrs. Remis and somehow he made it back to his lab station without passing out. Upon making his way back to the lab station, Ryan saw John trying to light the Bunsen burner. “John, John, your hair!” Ryan yelled in an excited voice.

“That was a close one,” said John. “My mother has been telling me to get a haircut. I guess I really need one now that I just lost a big chunk of my hair.” The two partners then proceeded with the lab. Ryan reached across the flame in order to get a beaker filled with acetic acid while John grabbed a test tube to put the chemical in.  “Oops!” said Ryan, “I just spilled some of the chemicals on the tabletop. I’ll just wipe it up with my shirt sleeve.”  “Should you tell Mrs. Remis?” John asked.  “No, it isn’t a big deal, I already wiped it up,” Ryan nonchalantly said. A few seconds later, Ryan said, “Man, my arm is warm.”  In an excited voice, John said, “Oh my Gosh, look at your shirt, there is a hole in it. That chemical you wiped up must have eaten through your shirt. How is your arm?”  Ryan said, “It hurts a little, but I will be fine.”  “Should we tell Mrs. Remis?” asked John.  “No, I’ll be fine,” Ryan said confidently. The lab partners then poured some chemicals into a test tube to begin heating. “Ryan, do you see that crack in the test tube?” questioned John.  “Who cares,” Ryan whispered. “As long as the test tube is not leaking, it must be fine.” The boys proceeded to heat the test tube. Ryan asked, “Is anything happening?”  “I don’t know, point the test tube in this direction so that I can look into the opening,” John replied.  “Maybe we should just add some of the other chemicals if nothing is happening yet,” said Ryan.  “Should we ask Mrs. Remis?” wondered John. “No, she is annoying,” Ryan smugly said. Ryan then continued, “She will first ask us if we read all of the procedures and then he will say, ‘I put a lot of time and effort into writing these labs for you guys and the least you could do is read them. If you have read it and then have additional questions, I would be more than happy to help you, but you have to do your part first.’  I certainly don’t want to hear all of that, do you?”  “Definitely not, I hate when teachers go ranting,” said John.  The lab partners proceeded to add some random chemicals to the test tube.  Shortly thereafter, the contents of the test tube began to bubble over. “Wow that was amazing!” Ryan yelled.  “Yeah, that was pretty cool, but it is everywhere,” John said in a concerned voice. “Good thing we have all of these papers laying around our lab station because most of the chemicals have just spilled onto them. We can just throw all of the papers into the garbage,” Ryan said confidently.  “Hey, it got onto my planner,” John said in an annoyed voice.  “Who cares, just go to guidance and buy another one for four dollars and fifty cents. Oh, I’m sorry, I mean you can get one for four dollars and Fitty Cent. Get it, Get it!” Ryan said in a joking manner.  The students began to clean up the spilled chemicals when John said, “This stuff smells really good, kind of like lemonade.”  “Well, if it smells like lemonade, it must be lemonade, just taste it,” Ryan said in a convincing manner.  John proceeded to taste the chemical mixture by sipping what was left in the test tube.  “Oh man, the bell is going to ring soon,” Ryan said in a rushed voice.  “Just leave it, I really want to go to lunch because it is Taco Day,” John said.  “Are you sure?” Ryan questioned.  “Yeah let’s just get out of here; the next class is going to be doing the lab again anyway, so they can clean it up,” John said.  Without washing their hands, Ryan and John left the classroom and headed to lunch.
