When observing, assisting, or leading a high school or undergraduate chemistry lab, the statement that is frequently said and heard is the reminder to put on safety goggles. Often times students will forget about wearing their goggles or they will place their goggles on their foreheads, instead of covering their eyes. The have been personal experiences where students will argue with the instructor about not wearing their goggles during an experiment. The distaste of the safety goggles typically comes from the comfortability of the goggles (1), and students will remove their goggles as soon as possible. Once an instructor notices the improper placement of the goggles, the whole lab hears the loud statement of “PUT ON YOUR GOGGLES PLEASE.” The students’ spines may tighten when hearing the reminder several times during a single experiment, but they should not blame the instructor. Wearing the appropriate eye protection correctly is …show more content…
Sharpless was an assistant professor at the Massachusetts Institute of Technology (MIT) in the year 1970. Dr. Sharpless noted that he always wore eye protection in the lab, except for this one occasion. He was checking on a new student in the graduate program while the student was sealing a NMR tube. Two major mistakes occurred while aiding the new student. The first mistake was not looking up how to properly seal the NMR tube, and the second was Dr. Sharpless not wearing his goggles. While taking the tube out of liquid nitrogen, the solvent inside the tube exploded causing shards of glass to enter one of Dr. Sharpless’s eyes. This lab accident cause Dr. Sharpless to lose his vision completely in the eye that was impacted by the glass shards. Dr. Sharpless ends his story with a message for the students who complain about wearing their goggles. This message is “the lesson to be learned from my experience is straightforward: there's simply never an adequate excuse for not wearing safety glasses in the laboratory at all times”
Following set instructions and guidelines is vital when conducting experiments in Chemistry, as it requires the handling of harsh chemicals. Paramedics have patients and colleague’s safety at their best interest, whilst providing pre-hospital care, hence maintaining precision and accuracy is
Before conducting the Activity Series Lab, participants must know how to protect themselves against the possible dangers that the hazardous materials from the lab can cause. Some of the things they must understand include proper safety precautions and how to protect against corrosive or poisonous materials. For instance, Copper (II) Chloride, one of the solutions used in the lab, can cause severe eye irritation. One way to protect against this is by wearing goggles, or other eye protection equipment. Another substance used in the lab is Silver Nitrate, a body tissue irritant. Participants must wash off the substance quickly if it comes into contact with their skin to prevent any serious damage. Not only is it vital to know how to be safe around the chemicals, but to fully understand the lab, participants must be able to recognize the clues to a chemical change.
There are many hazards in different scientific environments, in this assessment the Jack Hunt School Science Laboratory, the Peterborough Power Station and the Jack Hunt School Kitchens will be the different scientific environments observed. The hazards in each environment, the safety legislation that is put in place to prevent danger as well as other safety measures that are taken by those who work in these environments will be explained.
Safety glasses: Wear safety glasses to protect eyes from substances, acids and flames that can irritate or damage the eyes.
Our high school AP Chemistry classroom will be highlighted by productive learning advancements in both content knowledge and laboratory application. The classroom will have a work-oriented environment similar to industrial laboratories, but the students will perform in a pleasant atmosphere. This relaxed atmosphere will influence the students in engaging the material in an excited manner. This connects with my referent/expert authority basis (Levin, 2005), in which, influences my classroom structure and atmosphere to promote the professional practices of chemistry while forming positive relationships that will enhance productive learning. In order to demonstrate and obtain a safe environment, safety and organizational rules and procedures (only
Wore clean, intact safety glasses to avoid any splashes of chemicals that may contact the eye, and recorded qualitative data of reactants, such as colour, odour, shape etc., of hydrochloric acid and magnesium metal ribbon prior to the experiment.
Before starting this practical ensure you have sufficient PPE including lab coat, safety goggles and latex gloves.
Eyes are one of most important organ of our body, so it is important to choose suitable safety goggles or glasses as a protection against injury while doing a hazardous task. EyeglassRx is an online resource for safety goggles and latest eyeglass lens technology at a fraction of the cost.
My motivation to learn more about the eye and its processes, as well as neuroscience and optical diseases are just two of the subjects I look forward to learning more about from the optometry program. Learning more about the body and its processes has been the most interesting subject for me. Ever since my parents began developing illnesses, such as diabetes, I have been determined to better understand the body’s
These places would be surgery, fluoroscopy, staying in the room to hold the patient, and when performing mobile exams. While being involved in one of those tasks, you must prepare yourself. This includes wearing a lead apron that covers your chest and gonadal area, along with a thyroid collar, and even lead glasses. A long term effect of radiation exposure is cataracts. If you are constantly in the surgery room using the c-arm or o-arm, or you are performing fluoroscopy exams left and right, you should wear lead glasses to protect your eyes. While performing an exam in the department, you should always stand behind the lead wall before pressing the exposure button. This guarantees that the scatter radiation will not make its way to you. If you have a patient that needs to be held throughout the exam, a technologist should be the last person to hold; a family member, friend, or even someone outside of the department should help hold the patient because they are exposed to less radiation on a daily
The lack of doors, roofs, and most importantly seatbelts most people think that there is no way to be safe while riding, but with the correct safety gear such as helmets and leather layers could protect in accidents and falls. In the article “Mid-Life and Motorcycles a Bad Mix for Beginners: Highway Patrol Wants New Approach.” by Matt Bise he states, “So far in 2017 of the 63 killed (at the time of the meeting) two were age 20 or under, the rest were 21 and older; of those, 87 percent were not wearing a helmet or safety gear. Forty-two percent of the crashes involved just the rider” (Bise). Regardless of age it is imperative to wear the proper gear at all times to reduce the chance of a fatal injury. With the gear you are still at risk when falling or getting into an accidental but the gear prevents most the injury and can keep most of the impact.
There were multiple safety concerns that weren’t attended to. The biggest safety concern was that they weren’t wear eye goggles. By wear eye goggles they would have protected their eyes from the harsh bubble solution which could have blinded. They should have also wore gloves which would have protected their skin from the harsh chemicals in the solutions. Without wearing gloves they boys could have got a rash from the chemicals. Besides, gloves and goggles they should have wore a lab coat which would have protected their bodies and clothing.
(i). Working with chemicals, or other experiments, always wear safety goggles/eye production , to prevent chemicals/glass from going in your eye.
Care should be taken when handling beakers, graduated cylinders, and any other glassware. It is also important to make sure beakers and graduated cylinders are not slippery, to prevent accidents. Since hydrochloric acid is harmful, even at low concentrations, glasses must be worn when using and handling it. Crystal violet also stains, so to avoid getting it on skin and clothing, gloves and an apron can be used if desired. Also be careful when pouring or using any of the chemicals, because they can cause irritation and can be harmful to skin and eyes.
