1.
What is asbestos?
Correct Answer
A. A naturally occurring group of mineral fibers.
Explanation
Asbestos is a naturally occurring group of mineral fibers. It is not an organic compound derived from a plant or a natural element on the Periodic Table. Asbestos has been widely used in construction and manufacturing due to its heat resistance and durability. However, it is now known to be highly toxic and a major health hazard, causing serious respiratory diseases such as lung cancer and mesothelioma.
2.
Why was asbestos used?
Correct Answer
B. Its insulation capabilities and it is resistant to heat, fire and chemicals.
Explanation
Asbestos was used because of its insulation capabilities and resistance to heat, fire, and chemicals. These properties made it an ideal material for construction and insulation purposes, as it provided protection against heat and fire hazards. Additionally, its resistance to chemicals made it suitable for use in industries where exposure to corrosive substances was common. The use of asbestos was not solely due to its cost, but rather its advantageous qualities that made it a desirable material for various applications.
3.
Which of these compounds is asbestos?
Correct Answer
D.
Explanation
A. Silicon
B. Sodium
C. Corn meal
D. Asbestos
4.
Where can asbestos be found in homes?
Correct Answer
D. All of the above
Explanation
Other locations may include around hot water pipes, around oil and coal furnaces, and in textured paint used on walls.
5.
A long term health effect of asbestos exposure may include...
Correct Answer
B. Lung cancer or mesothelioma
Explanation
Long-term exposure to asbestos can lead to the development of lung cancer or mesothelioma. Asbestos fibers, when inhaled, can cause inflammation and scarring in the lungs, leading to the formation of cancerous cells over time. Mesothelioma, a rare and aggressive cancer that affects the lining of the lungs, abdomen, or heart, is specifically associated with asbestos exposure. These health effects occur due to the carcinogenic nature of asbestos, highlighting the importance of avoiding prolonged exposure to this hazardous material.
6.
The symptoms of asbestos exposure typically occur within a month of exposure.
Correct Answer
B. False
Explanation
Symptoms typically take many years to develop following exposure.
7.
Smoking combined with previous exposure to asbestos is particularly hazardous.
Correct Answer
A. True
Explanation
Smoking combined with previous exposure to asbestos is particularly hazardous because both smoking and asbestos exposure individually increase the risk of developing lung cancer. When these two factors are combined, the risk becomes even higher. Smoking damages the lungs and weakens the body's defense mechanisms, making it more susceptible to the harmful effects of asbestos fibers. Asbestos, on the other hand, can cause scarring and inflammation in the lungs, which can increase the likelihood of developing cancer. Therefore, the combination of smoking and previous asbestos exposure poses a significant health risk.
8.
For asbestos used for construction use, in what situations increase the risk of unnatural exposure?
Correct Answer
C. During demolition.
Explanation
During demolition, there is a higher risk of unnatural exposure to asbestos used for construction. This is because during the demolition process, asbestos-containing materials can be disturbed, releasing asbestos fibers into the air. These fibers can then be inhaled, increasing the risk of health issues such as lung diseases. It is important to take proper precautions and follow safety guidelines during demolition to minimize the risk of exposure to asbestos.
9.
In 1989, The U.S. Environmental Protection Agency banned all new and existing uses of asbestos.
Correct Answer
B. False
Explanation
Uses of asbestos developed before 1989 are still allowed. Materials that use asbestos today undergo strict testing and have to be deemed environmentally safe.
10.
If asbestos is detected, how should it be removed or repaired safely?
Correct Answer
B. By a trained asbestos inspector or contractor.
Explanation
Homeowners should ensure that workers they hire to handle asbestos are trained and accredited.
