1.
Long hair, loose clothing and dangling jewelry are:
Correct Answer
B. All safety hazards.
Explanation
Long hair, loose clothing, and dangling jewelry can pose a safety hazard in a laboratory setting. Long hair can get caught in equipment, loose clothing can easily catch fire or get entangled in machinery, and dangling jewelry can get caught in equipment or chemicals. Therefore, it is important to avoid these attire choices in order to maintain a safe laboratory environment.
2.
Strong smelling perfumes, deodorants and soaps can __________sensory testing.
Correct Answer
interfere with
positively impact
be used to support
Explanation
Strong smelling perfumes, deodorants, and soaps can interfere with sensory testing. The strong scents from these products can overpower or distort the senses, making it difficult to accurately perceive and evaluate sensory stimuli. On the other hand, they can also positively impact sensory testing by enhancing certain sensory experiences, such as creating a pleasant or stimulating environment. Additionally, these products can be used to support sensory testing by providing standardized stimuli or control conditions.
3.
Appropriate shoes to wear in the Anderson laboratory are (choose the best answer):
Correct Answer
D. Steel Toed Safety Shoes
Explanation
The Anderson laboratory requires shoes that provide safety and protection. Sandals and open-toed shoes do not offer adequate coverage and can expose the feet to potential hazards. Stilettos are not suitable as they are high-heeled and can be unstable in a laboratory setting. On the other hand, steel-toed safety shoes are designed to protect the feet from heavy objects, falling objects, and other potential dangers in a laboratory environment, making them the most appropriate choice.
4.
Steel Toed Safety Shoes and Safety Glasses are required upon entering the laboratory (True or False).
Correct Answer
A. True
Explanation
Steel toed safety shoes and safety glasses are required upon entering the laboratory, regardless of whether someone is working on the bench or not. This is because the laboratory environment can be hazardous, with the potential for falling objects or chemical splashes, and wearing these safety equipment helps to protect against such risks.
5.
A lab coat is not needed if wearing a factory issued uniform (True or False)
Correct Answer
B. False, lab coats are worn over both uniforms and street clothes as a barrier of protection against spills and biological contamination.
Explanation
The correct answer is False because lab coats are worn over both uniforms and street clothes as a barrier of protection against spills and biological contamination. This means that even if someone is wearing a factory issued uniform, they still need to wear a lab coat for added protection.
6.
Contact lenses may be worn with safety glasses (True or False).
Correct Answer
B. False, contact lenses are permeable to vapors which cause irritation.
Explanation
Contact lenses are permeable to vapors, which means that they allow vapors to pass through and come into contact with the eyes. This can cause irritation and discomfort when exposed to certain substances or environments. Therefore, wearing contact lenses with safety glasses may not provide adequate protection against vapors and can lead to irritation.
7.
Food and drink are permissible in the laboratory (choose best answer):
Correct Answer
C. Never.
Explanation
The correct answer is "Never" because food and drink should never be permitted in the laboratory. This is because laboratory environments require strict hygiene and safety protocols to prevent contamination and accidents. Consuming food or drinks in the laboratory increases the risk of introducing foreign substances or chemicals into experiments, compromising the accuracy and safety of the work being conducted. Therefore, it is essential to strictly prohibit the presence of food and drink in the laboratory at all times.
8.
