What are the general rules in the use of cleaning equipment?
Rules for the use of cleaning equipment depend on the type of cleaning equipment is being used. Using the equipment safely would be a general rule. Keeping the equipment clean and in good condition is another general rule. Other general rules might be storing the equipment properly, storing chemicals properly, and using the correct chemicals.

What is controvition of a sir Alexander Fleming?
Alexander Fleming discovered the antibiotic penicillin in 1928, but his discovery faced controversy as he initially failed to fully recognize its potential medical uses. This led to delays in its development and widespread use for treating bacterial infections. Despite this, Fleming's work laid the foundation for the use of antibiotics in modern medicine.
Which famous scientist discovered penicillium notatum?
Alexander Fleming is credited with the discovery of penicillium notatum in 1928. He observed its antibacterial properties and its potential for use as an antibiotic, leading to the development of penicillin.
Who was Dr Cecil Paine?
He was the first person ever to use penicillin, he worked with Sir Alexander Fleming.
How did Alexander Fleming use mold to discovered penicillin?
Alexander Fleming discovered penicillin by observing that mold (Penicillium) had antibacterial properties. He noticed that a mold contaminant in one of his petri dishes was preventing bacterial growth. This led to the development of penicillin, the first antibiotic.
What type of math did Alexander Fleming use?
At a guess exponentials, series and statistics would have been important in studying micro-organisms.
Why did Alexander Fleming find penicillin hard to work with?
Alexander Fleming found penicillin hard to work with because he struggled to isolate and purify the compound from the mold, which was a time-consuming and challenging process. Additionally, the mold produced penicillin in small quantities, making it difficult to obtain enough for effective use.
What problems did Alexander Fleming have to overcome?
Alexander Fleming had to overcome challenges such as obtaining funding for his research, designing experiments to demonstrate the efficacy of penicillin, and isolating and purifying the compound to make it suitable for clinical use. Additionally, he faced skepticism from the medical community, convincing them of the potential of penicillin as a new treatment for bacterial infections.
Who is Alexander Fleming and what he do?
Fleming discovered that penicillin was a mould that could kill certain types of bacteria that caused disease. The Use of penicillin did not begin until the 1940s when Howard Florey and Ernst Chain made a powder form of penicillin
What did Alexander Fleming fear?
Alexander Fleming feared the misuse of antibiotics, particularly the potential for bacteria to develop resistance due to overuse and improper use of these medications. He warned that antibiotics should be used judiciously to avoid creating "superbugs" that could render treatments ineffective. Fleming recognized the transformative power of penicillin but understood that it could lead to serious public health issues if not managed responsibly.
How did Alexander Fleming use the scientific method?
Alexander Fleming used the scientific method by making observations of mold killing bacteria in a petri dish, forming a hypothesis that the mold could have antibacterial properties, testing this hypothesis through experiments, and analyzing the results to draw conclusions. His systematic approach led to the discovery of penicillin, the first antibiotic.
What would have happened if Alexander Fleming didn't make his discoveries?
If Alexander Fleming didn't make his discoveries, it is possible that the development of penicillin, the first antibiotic, would have been delayed. This delay could have impacted medical treatments for bacterial infections and potentially led to higher mortality rates from such infections. Fleming's work laid the foundation for the use of antibiotics in modern medicine.
What could be treated as a result of Alexander Fleming's discover of penicillin?
Alexander Fleming's discovery of penicillin came about by accident. Fleming was an untidy worker, often leaving his equipment uncleaned. When he went away for a holiday during 1828, he left a clutter of plates growing various bacteria lying about his desk. After he returned, whilst working on an influenza virus he noticed that mould had grown on a staphylococcus culture plate. Not only that, the mould had created a bacteria-free circle around itself. Working on an hypothesis, he experimented further to determine that even a weaker-strength mould culture prevented growth of staphylococci. Thus, Fleming initiated the development and practice of antibiotic therapy for infectious diseases.
