Safety story
This symbol is a flammable symbol. This one mean that the product is possible fire hazard, so it can catch fire easily.
This symbol is a poison can cause death symbol. This one mean that the product is able to cause death or severe poisoning.
The red shape that looks like a stop sign shows that the product is extremely not safe to consume or touch or bring close to fire.
The orange shape that is a diamond shows that the product must me stored of carefully.
The yellow shape that looks like a yield sign shows that you should still be careful with it, but it isn’t deadly.
It was just a regular day in Mr. Robinson’s science 9 class. The class was talking in their table groups about the Lab equipment they got selected to talk about how they think that you can use the pieces of equipment. Group one was talking about the pipestem triangle. They came up with this idea of what it does, and it was correct. They said, “supports the crucible being heated over an open flame”. Group two was talking about the micropipets. The group came up with an idea of what the micropipets are used for, their guess was incorrect. They said, “fill up the pipets to the top and dispense however much liquid you want”. Group 3 was assigned to talk about what the test tubes. Group 3 came up with this idea, their answer was incorrect on how to use it. They said, “fill the tubes with liquids to the very top of the tube”. Group 4 was told to talk about the mortar and pestle. They thought of an idea on how to use it, it was correct. They said, “its for grinding chemicals to powder”. Finally group 5 the last group was assigned to talk about the wire brush. The final group thought of an idea, that was very close but incorrect. They thought that wire brush is used for “cleaning micropipets, droppers and a regular pipet”. After the groups finished discussing about their items, they started getting ready for the lab. Mr. Robinson brought in the chemicals we are going to investigate. As he was walking over to group one to give the group their stuff someone left their backpack out and didn’t tuck it under the group table. Mr. Robinson tripped over the bag and the chemicals went everywhere. It was a chemical in the warning category, so it wasn’t going to kill the student that got the chemical on their body, so they went to the eye wash station and the shower station and pulled the handle and turned on the water for eye wash. Luckily the student was okay, and everyone finished the lab after a little bit of clean up and we got to the bins, and we couldn’t decide what bin to but the stuff that we cleaned the chemical up with. Should we put it in a recycler or should we put them in EHS Hazardous waste program. We ran into a dilemma. In the end the class chose the recycler.
It was a great day in Mr. Robinsons science 9 class. The class was talking in their table groups about the Lab equipment they got selected to talk about how they think that you can use the pieces of equipment. Group one was talking about the pipestem triangle. They came up with this idea of what it does, and it was correct. They said, “supports the crucible being heated over an open flame”. Group two was talking about the micropipets. The group came up with an idea of what the micropipets are used for, their guess was correct. They said, “to measure and dispense very small amounts of liquids”. Group 3 was assigned to talk about what the test tubes. Group 3 came up with this idea, their answer was correct on how to use test tubes. They said, “Holds small amounts of liquids for mixing and heating”. Group 4 was told to talk about the mortar and pestle. They thought of an idea on how to use it, it was correct. They said, “its for grinding chemicals to powder”. Finally group 5 the last group was assigned to talk about the wire brush. The final group thought of an idea, that was correct. They thought that wire brush is used for “to clean the inside of test tubes or graduated cylinders”. After the groups finished discussing about their items, they started getting ready for the lab. Mr. Robinson brought in the chemicals that we are going to investigate. As he was walking over to group one to give the group their stuff, and he noticed everyone tucked their bags under the group table. Mr. Robinson was very happy to see that his students are being safe. So, he continues to bring the chemicals to the groups. It was a chemical in the warning category, so it was a warmup lab to get into the swing of things. Luckily the students were all okay, and everyone finished ended up finishing the lab. The class went over to the bins happy that no one got hurt, and we couldn’t decide what bin to but the stuff the left-over chemicals. Should we put it in a recycler or should we put them in EHS Hazardous waste program. We ran into a dilemma. The class chose the EHS Hazardous waste program.
