The Most Common Injuries in a Chemistry Lab

The Most Common Injuries in a Chemistry Lab There are a lot of hazards in a chemistry lab. Youve got chemicals, breakables, and open flames. So, accidents are bound to happen. However, an accident doesnt necessarily have to lead to an injury. Most common injuries can be prevented by minimizing accidents by being careful, wearing proper safety gear, and knowing what to do in the event of an emergency. OSHA keeps track of reported injuries, but most of the time people get hurt, its either not something they admit to or else not a life-threatening event.  What are your biggest risks? Heres an informal look at common injuries. Eye Injuries Your eyes are at risk in the chemistry lab. If you normally wear contacts, you should wear glasses to lessen chemical exposure. Everyone should wear safety goggles. They protect your eyes from chemical splashes and errant shards of glass. People get eye injuries all the time, either because they are lax about wearing protective eyewear, the agent causing the injury gets around the edge of the glasses, or they dont know how to use the eyewash properly. While cuts are more common in the lab, eye injuries are probably the most common serious wounds. Cuts from Glassware You can cut yourself being stupid, trying to force glass tubing through a stopper with the palm of your hand. You can cut yourself breaking glassware or trying to clean up a mess. You can cut yourself on a sharp edge of a piece of chipped glassware. The best way to prevent the injury is to wear gloves, yet even so, this is the most common injury, mainly because few people wear gloves all the time. Also, when you do wear gloves, you lose dexterity, so you may be more clumsy than usual. Chemical Irritation or Burns Its not just the skin on your hands that is at risk from chemical exposure, although this is the most common place to get hurt. You can inhale corrosive or reactive vapors. If youre extra-stupid, you can ingest harmful chemicals by swallowing liquid from a pipette or (more commonly) not cleaning up well enough after lab and contaminating your food with traces of chemicals on your hands or clothing. Goggles and gloves protect your hands and face. A lab coat protects your clothing. Dont forget to wear closed-toe shoes, because spilling acid on your foot is not a pleasant experience. It does happen. Burns from Heat You can burn yourself on a hot plate, accidentally grab a piece of hot glassware, or burn yourself by getting too close to a burner. Dont forget to tie back long hair. Ive seen people set their bangs on fire in a Bunsen burner, so dont lean over a flame, no matter how short your hair is. Mild to Moderate Poisoning Toxicity from chemicals is an overlooked accident because the symptoms may resolve within minutes to days. Yet, some chemicals or their metabolites persist in the body for years, potentially leading to organ damage or cancer. Drinking a liquid accidentally is an obvious source of poisoning, but many volatile compounds are dangerous when inhaled. Some chemicals are absorbed through the skin, so watch spills, too. Tips to Prevent Lab Accidents A little preparation can prevent most accidents. Here are some tips to keep yourself and others safe: Know the safety rules for working in the lab (and follow them). For example, if a certain refrigerator is labeled No Food, dont store your lunch there.Actually use your safety gear. Wear your lab coat and goggles. Keep long hair tied back.Know the meaning of lab safety signs.Label containers of chemicals, even if they only contain water or other non-toxic materials. Its best to put an actual label on a container, because grease pen marks may be wiped off during handling.Make certain safety gear is maintained. Know the schedule for purging the line of an eyewash. Check the ventilation of chemical fume hoods. Keep first aid kits stocked.Quiz yourself to see if youre safe in the lab.Report problems. Whether its faulty equipment or a mild accident, you should always report an issue to your immediate supervisor. If no one knows there is a problem, its unlikely to get fixed.

Helping Students Move Beyond General Goals

Helping Students Move Beyond General Goals Once you have determined a general goal and you think you know why it appeals to you, you are ready to write it in a way that will help you make it happen. Goals Studies of successful people have shown that they write goals that contain similar elements. To write a goal like winners do, be sure that: It is stated in a positive way. (eg. I will... not, I might or I hope...It is obtainable. (Be realistic, but dont sell yourself short.)It involves your behavior and not someone elses.It is written.It includes a way to measure successful completion.It includes the specific date when you will begin working on the goal.It includes a projected date when you will reach the goal.If it is a big goal, it is divided into manageable steps or sub-goals.The projected dates for working on and completion of sub-goals are specified. Despite the length of the list, great goals are easy to write. The following are examples of goals containing the necessary components. General Goal: I will be a better basketball player during this year.Specific Goal: I will get 18 baskets in 20 tries by June 1, 2009.I will begin working on this goal January 15, 2009.General Goal: I will become an electrical engineer some day.Specific Goal: I will have a job as an electrical engineer by January 1, 2015.I will begin working on this goal February 1, 2009.General Goal: I will go on a diet.Specific Goal: I will lose 10 pounds by April 1, 2009.I will begin dieting and exercising February 27, 2009. Now, write your general goal. (Be sure to start with I will.) _________________________________________________________________________________________________________________________________________________________________________________________________ Now make it more specific by adding the manner of measurement and projected completion date. _________________________________________________________________________________________________________________________________________________________________________________________________ I will begin working on this goal on (date) _______________________________ Considering how completing this goal will benefit you is quite important because this benefit will be the source of motivation for the work and sacrifice needed to complete your goal. To remind yourself why this goal is important to you, complete the sentence below. Use as much detail as you can by imagining the goal completed. Begin with, I will benefit by meeting this goal because... _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Because some goals are so big that thinking about them makes us feel overwhelmed, it is necessary to break them into sub goals or the steps you need to take in order to meet your major goal. These steps should be listed below along with a projected date for completion. Creating Sub-Goals Since this list will be used to schedule your work on these steps, you will save time if you set up a table on another piece of paper with a wide column for listing the steps, and a number of columns to the side which will eventually be used to indicate time periods. On a separate sheet of paper, make a table with two columns. To the right of these columns, attach gridded or graph paper. See the image at the top of the page for an example. After you have listed the steps you will need to complete in order to attain your goal, estimate the date by which you can complete all of them. Use this as your projected ending date. Next, turn this table into a Gantt chart by labeling columns to the right of completion date with appropriate time periods (weeks, months, or years) and color in the cells for the times you will work on a particular step. Project management software usually contains features for making Gantt charts and make the job more fun by automatically changing related charts when you make a change in any one of them. Now that you have learned to write a great specific goal and to schedule sub-goals on a Gantt chart, you are ready to learn how to maintain your motivation and momentum.
