causes of accidents in the laboratory

In conclusion, accidents can and do happen in the chemistry lab. These need to be understood well before the accident process begins. This was illustrated by the first laboratory-acquired case of severe acute respiratory syndrome (SARS) coronavirus, which occurred 4 months after the end of the SARS epidemic [2]. However, a greater risk of infection is likely on the aerobic culture bench, because colonies of B. dermatitidis and C. immitis can grow on routine media and may be visible within 23 days. Exposures may occur inadvertently, may not even be recalled, or may result from lapses in technique leading to accidental inoculation. To do this, they pour whole blood into the center of the machine, where it is spun rapidly. 1. Here are some ideas to help you prevent injuries. What does it mean to call a minor party a spoiled? He was discharged from the emergency department but returned 5 days later because of persistent fever. reagent is a chemical compuond that causes a reaction. Over 90% of the causes under this category were mere accidental breakage of glassware or damage of equipment. Speaking with the injured party as close as practical to the time of the event will ensure better recall of potentially related or causative factors. For example, one might add water to sodium hydroxide (NaOH) without paying attention what will happen. However, no denominator data have been provided that would help determine the actual risk or incidence of infection for laboratory workers. The Centers for Disease Control and Prevention has recently convened a committee to address these issues that will, I hope, provide evidence-based guidelines on exposure risk and use of PEP. Where possible, metrics should be integrated into existing systems (e.g., laboratory inspections or audits) to streamline the performance improvement process. Nonimmunized laboratory workers who have percutaneous, ocular, or mucous membrane exposure to contaminated blood should receive PEP with hepatitis B immunoglobulin and vaccine [39]. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. It isn't dumb to ask questions; it's dumb not to. Good housekeeping involves both pride and safety.

In contrast, the highest incidences of infection were associated with Brucella species (641 cases per 100,000 laboratory technologists, compared with 0.08 cases per 100,000 persons in the general population) and Neisseria meningitidis (25.3 cases per 100,000 laboratory technologists, compared with 0.62 cases per 100,000 persons in the general population). Sixteen cases of probable laboratory-acquired meningococcal disease were identified, including 6 cases in the United States. Civil defence teams responded to more than 3,000 incidents in 2022, including 2,169 building fires up 3 per cent from 2,090 in 2021 and 10 per cent from 1,968 in 2020. These workers are exposed to a variety of pathogenic microorganisms that may put them at risk of infection. It is encouraging that, in the 2 most recent surveys of laboratory-acquired infections in the United Kingdom, there were no reported cases of HBV infection among laboratory workers [8, 9]. What kinds of injuries can you get in a chemistry lab? To avoid injury, keep your space clean and orderly. A uniform approach to conducting both the site investigation and the interviews is essential for consistency. Careless acts can lead to injuries at work, which can have serious consequences for your health and well-being. Of the common blood-associated viruses, hepatitis B virus (HBV) is the most common cause of laboratory-acquired infection [1]. Students may fail to wear protective clothing when working with chemicals. Causes and effect of work accidents in the laboratory Satria Wijaya 1. One case of giardiasis was reported in a clinical laboratory technologist who processed specimens, many of which were in leaky containers. [31] described 12 laboratory workers who were exposed to F. tularensis after clinicians failed to notify the laboratory about a suspected case of pneumonic tularemia in a 43-year-old man who eventually died. Chemical spills can occur when chemicals are improperly stored or handled. Generally, science accidents result from the following factors (Causes of accidents in the laboratory): Fires - Electrical short circuits and shocks - Leaks and spills - Unplanned storage- Use of defective material handling equipment - Careless handling of containers. Of these incidents, 20 were classified as major fires, 37 as medium fires and the remaining were considered minor. Don't be shy about asking for explanations about work procedures and safety precautions. Certain accidents that involve a release of material to the indoor or outdoor environment will require an initial response that may compromise the ability to collect all the necessary information. Laboratory safety guidelines are established to ensure the highest safety standards within your lab. characteristics of accidents and the causes of accidents through statistics of 50 college laboratory accidents in recent years.
