Sand or flour can be used instead of a fire blanket.
-
True
-
False
Correct Answer
A. TrueExplanation
Sand or flour can be used as an alternative to a fire blanket because they can smother a fire by cutting off the oxygen supply. When thrown onto a fire, sand or flour can create a barrier between the flames and the surrounding air, effectively extinguishing the fire. While fire blankets are specifically designed for fire suppression and are more effective, in certain situations where a fire blanket is not available, sand or flour can be used as a temporary solution to control a small fire.Rate this question:

A good method to test whether a knife is sharp is to run your finger along the cutting edge of the knife.
-
True
-
False
Correct Answer
A. FalseExplanation
Running your finger along the cutting edge of a knife is not a good method to test whether it is sharp because it can be dangerous and result in injury. A safer and more effective method to test the sharpness of a knife is to use a piece of paper or a vegetable to see if it cuts through easily and cleanly.Rate this question:

Sharp knives are safer to use than blunt knives.
-
True
-
False
Correct Answer
A. TrueExplanation
Sharp knives are safer to use than blunt knives because they require less force to cut through objects, reducing the risk of slipping and causing accidental injuries. Additionally, sharp knives provide cleaner cuts, minimizing the chances of the knife slipping off the object and causing harm. With a blunt knife, more pressure is needed, increasing the likelihood of losing control and potentially causing accidents. Therefore, it is generally recommended to use sharp knives for safer and more efficient cutting.Rate this question:

Bacteria need a warm environment above 60°C in order to grow.
-
True
-
False
Correct Answer
A. FalseExplanation
Bacteria do not need a warm environment above 60°C in order to grow. In fact, most bacteria have an optimal temperature range for growth, and this range varies depending on the type of bacteria. While some bacteria may thrive in warmer temperatures, many can grow and reproduce at lower temperatures, including room temperature or even in cold environments. Therefore, it is incorrect to say that bacteria require a warm environment above 60°C for growth.Rate this question:

Symptoms of food poisoning almost always occur as soon as the contaminated food is eaten.
-
True
-
False
Correct Answer
A. FalseExplanation
The statement is false because symptoms of food poisoning do not always occur as soon as the contaminated food is eaten. In some cases, symptoms may take several hours or even days to appear. This delay is due to the time it takes for the bacteria or toxins to multiply and affect the body. Therefore, it is important to be aware that symptoms can occur after a certain period of time and not immediately after consuming contaminated food.Rate this question:

If you spill water on the floor, wipe it up quickly with a tea-towel.
-
True
-
False
Correct Answer
A. FalseExplanation
The statement suggests that if you spill water on the floor, you should wipe it up quickly with a tea-towel. However, this is not necessarily true. While it is important to clean up spills to prevent accidents and damage, using a tea-towel may not be the most effective or appropriate method. Depending on the type of floor and the amount of water spilled, other tools such as a mop or absorbent towels may be more suitable for cleaning up the spill. Therefore, the correct answer is False.Rate this question:

Food that is contaminated and can cause food poisoning will usually taste ‘off’.
-
True
-
False
Correct Answer
A. FalseExplanation
Food that is contaminated and can cause food poisoning may not always taste 'off'. Some harmful bacteria, such as Salmonella or E. coli, do not produce noticeable changes in taste, smell, or appearance of the food. This is why it is important to practice proper food safety measures, such as cooking food thoroughly and maintaining proper hygiene, to prevent foodborne illnesses even if the food appears to be normal.Rate this question:

Fast-food outlets should keep food ready for sale between the temperatures of 5°C and 60°C so that it is safe to eat.
-
True
-
False
Correct Answer
A. FalseExplanation
Fast-food outlets should keep food ready for sale between the temperatures of 5°C and 60°C so that it is safe to eat. This statement is false. In reality, fast-food outlets should keep food ready for sale between the temperatures of 63°C and 74°C to ensure that it is safe to eat. This temperature range is known as the "danger zone" where bacteria can multiply rapidly, potentially causing foodborne illnesses. Keeping food at temperatures below 5°C or above 60°C helps to prevent bacterial growth and maintain food safety.Rate this question:

One bacterium can multiply to more than 17 million within one hour if it has the correct conditions for growth.
-
True
-
False
Correct Answer
A. FalseExplanation
The statement claims that one bacterium can multiply to more than 17 million within one hour if it has the correct conditions for growth. However, this statement is false. While bacteria can multiply rapidly under favorable conditions, it is highly unlikely for a single bacterium to multiply to such a large number within just one hour. Bacterial growth is influenced by various factors such as the type of bacteria, environmental conditions, and available nutrients. While exponential growth can occur, it would typically take a longer time for a single bacterium to reach a population of 17 million.Rate this question:
