Why is wafting used during a scientific experiment?
Wafting method is used in scientific experiments to avoid inhaling the chemical.
What safety rules should be followed in a science laboratory when wafting an unknown substance?
When wafting an unknown substance, it is extremely important to not take in a direct whiff. You need to breathe in only enough to get your sense of smell going. If you breathe in too much, you run the risk of severely harming yourself.
What are examples of bad lab safety?
Lots of behavior can be considered "bad lab" practice. Whenever one is in a lab where they are working with chemicals or biological material (or anything else that could be hazardous to their health) they must always practice good lab technique and safety. Outlined below is a list of the most important things to remember when in a lab situation: 1) always dress appropriately. Always wear protective clothing when working with potentially dangerous materials. Clothes toed shoes, lab coats, gloves if necessary and most importantly safety goggles. Some corrosive chemicals can easily burn sensitive areas like the eyes and can lead to blindness. 2) Always assume everything you are working with is dangerous. When in a biology lab, it can be sometimes hard to distinguish a colony of bacteria that can make you very sick compared to a harmless colony of bacteria. In chemistry some chemicals may look exactly alike, it can be difficult to tell by sight the difference between hydrochloric acid (which can painfully burn, I have a scar on my hand to prove it...see number one about the gloves) and water. 3) Never taste or smell unknown chemicals. This may sound like a given but there have been discoveries because careless chemists tasted their unknown product. In fact, that is exactly how saccharin was discovered which in turn let to the production of artificial sweeteners. You may not be so lucky, you may accidently taste something that is extremely hazardous. So just don't. If you need to smell a chemical, never put your nose directly over the chemical and inhale. Try this with ammonia and you will see how badly just the fumes from a chemical can burn. In order to smell a chemical, do what we call wafting. Wave your hand accross the chemical container, moving the air towards your nose. Trust me, if you are dealing with a chemical like ammonia, you will still most definitely be able to tell just from wafting the air. 4) Always dispose of chemicals properly. Neutralize acids and bases with reagents such as baking soda to make them safe to pour down the drain, never pour an unknown or a chemical known to be dangerous down the drain or in the regular trash. Whatever lab you are in should have a special way to dispose of hazardous chemicals. Ditto for a biology lab, we do not want to pour anything down the drain that could potentially infect our drinking water. If you wouldn't want to drink it yourself, do not pour it down the drain. Most biology labs also have special areas to dispose of biological waste. 5) Most importantly, if you are in a classroom lab, always listen to your lab instructor. Never get started without finding out all the facts of the substances you are working with and the procedures you are to follow.
What safety rules should be followed in a science laboratory?
Safety Rules and ProceduresKnow what WHMIS is, and what the Safety Sheets are to look at the different chemicals that are used within the lab environment.Know how to use the fire extinguishers, and when it is appropriate to use them.Report all injuries and illnesses to lab staff immediately, DO NOT wait!If you notice a gas leak, or other sort of leak, make sure that you mention to the lab staff.Clean up spills and broken glass and other equipment using the prescribed outlines that are provided by your lab. Some like mercury requires special precautionsIf you hear the fire alarm, close all doors to the lab, and make sure that you quickly turn off everything such as gas, and other components that you may be using. Then evacuate.Have regular safety meetings with the lab staff to go through policies and procedures that are needed while in the lab!Long hair tied back If you're wearing a tie tuck it inside your blouse/shirt or remove it to avoid accidents.If possible, stand up and put stools elsewhere so that if something spills then you can move back fasterKeep your desk (work area) cleanAlways wear either long sleeves or a lab coat due to splashing of chemicals. In addition, closed toe shoes are a must. So no sandals or flip flops! Be sure to roll up your sleeves or wear a short-sleeved shirt if you're working with heat or open flame.No food or drink in the lab - mistakes and contamination can be deadlyNo horseplay or practical jokes (focus on your work)Use of potentially dangerous chemicals limited to knowledgeable staffNo chipped or cracked glasswareLearn the proper insertion of rubber stoppers into glass tubesAll cuts burns etc. reported and treated, no exceptionsAll gas cylinders chained to the wallNo experiment left aloneNo "Wonder what happens if I do this" experimentsDo not pick up or move flasks or other containers holding chemicals unless absolutely necessary. Fewer mistakes means fewer accidents. When you must move a container, use BOTH HANDS to make sure you have a firm grip, and always make sure your travel path is clear.Read all labels thoroughly. Make sure you know what you're using and its proper use!Do not rush through instructions - pay close attention to all details, especially any precautionsalways watch out for spills and slippery liquids.The only safety rules for ANY laboratory that you are thinking about working in are the ones that the laboratory requires and should be clearly explained to you before you even enter it. The rest is opinion.
