There could be any number of reasons: All of this leads to all sorts of trouble, low grades being one of them. The deadlines are looming. The pile of homework grows.
But eye injuries are painful and sometimes permanent, and all it takes is a momentary lapse. Consider this example from an upper-division organic chemistry course at a small private college. He took a place at a shared Thesis occupational safety and health hood with two other students, one of whom was in the process of heating solvent in a flask.
At that moment the glass shattered, spraying solvent on all three students. Two of them were wearing eye protection. The new arrival, working next to the student whose flask had shattered, took solvent directly in both eyes.
One Friday afternoon, in her early days as a research technician at a major cancer research center, a researcher in a relatively new lab had just completed a gel run and was cutting out the band of purified DNA on an ultraviolet UV light box tray. None of the other researchers in the lab wore goggles or any other specialized eye protection.
As the day wore on, her eyes began to itch. She and her boyfriend went out to listen to a band after work, and her eyes became progressively worse, which she attributed at first to the smoky atmosphere in the bar.
By the end of the night, "it felt as though there were eyelashes in my eye," she recalls.
By Monday, she had recovered fully. Only after returning to the lab did she recognize the significance of an apparently mundane fact: The other researchers in the lab all happened to wear eyeglasses, which partially shielded them when they used the UV light box.
The lab immediately purchased two face shields. According to safety experts, standard eyeglasses may not offer sufficient protection; experts recommend protective equipment specific to the task at hand--including protected eyewear rated for protection from the range A, B, or C and intensity of the UV light source.
Fashion risks One common fallacy is that you only need eye protection when you are doing something dangerous. But laboratories are shared environments. Individuals with varying levels of competence are performing experiments and procedures with hazardous chemicals and agents, often under pressure or in a vacuum.
One reason for forgoing eye protection is blurred vision from fogged-up eyewear. Tapp admits that this problem can itself cause accidents, but she points out that solutions are available, including wipes that protect against fogging and fog-resistant specialty eyewear. This is a myth, says Gibbs, a holdover from the days when eye protection consisted solely of uncomfortable, oversized goggles that looked like they should have a snorkel attached to them.
Safety-glass manufacturers have taken pains to design eye protection that is comfortable and even stylish, so much so that they sometimes get put to unconventional uses. Some of them are quite stylish.
Eyewear manufacturers are taking these complaints to heart. In the design of its Genesis line of safety glasses, protective-eyewear manufacturer Uvex adopted a molding technology that allows different materials to be bonded together, much like the soft, pliable tip of a pen or handle of a toothbrush.
In the end, the most important factor is leadership by example. Gibbs agrees that leadership is a crucial factor. In microbiological and medical research labs with specialized microscopes and other imaging instruments, researchers often remove eyewear to take a reading.
Gibbs stresses risk awareness. The risk of an exposure at a microscope is low, but as soon as a researcher finishes that task and moves to another, the risk can change dramatically.
Consider the immunology graduate student who one morning felt her left eye began to swell and itch. Four days later, the eye had become swollen and painful, and she suffered malaise, fatigue, and a fever. When she was examined at an eye hospital, she mentioned that she had been working with Vaccinia, the virus used in the smallpox vaccine, and she was admitted to the hospital and started on broad-spectrum antibiotics and pain medication.
Polymerase chain reaction tests confirmed Vaccinia infection. Treatment with vaccinia immune globulin led to rapid improvement, and she was released, fully recovered, after a 9-day hospital stay.
A Centers for Disease Control and Prevention CDC investigation of the lab she worked in revealed that staff often failed to wear eye protection while working with Vaccinia. The DNA sequence of the virus that infected her corresponded to that of the specimen she had been using in an experiment performed 5 days before her symptoms began.
The exposure probably occurred when she carried a well plate containing Vaccinia-infected mammalian cells to another room, where she removed the lid of the plate and examined the cells for fluorescence.
CDC investigators concluded that exposure occurred either from hand-eye contact or from the aerosolization of the virus. Labs that handle viruses usually emphasize the prevention of skin contact, but even though "the probability of skin contact is higher, the outcome of eye contact is [of] higher severity," says Gibbs.The United States Occupational Safety and Health Administration (OSHA) stated that 'homicide is the fourth leading cause of fatal occupational injury in the United States' (alphabetnyc.com, ).
The concern of diseases as well as other health related problems and issues have been noted to affect the worker's performance, productivity levels and.
Abstract. It is widely acknowledged that Hong Kong teachers are suffering from work-related health and safety problems (HKPTU, ). Reviews of Occupational Safety and Health (OSH) research suggest that there is a wealth of scientific data on OSH to establish policy level interventions, yet the implementation of OSH legislation and policies is complex and multi-faceted.
The Master of Science in Occupational Safety and Health degree program provides students phd thesis in occupational health and safety with a flexible, relevant and current curriculum that includes opportunities for students to demonstrate a depth and breadth of knowledge in safety and health theory and technology necessary to lead and oversee.
