Test: Risk and Laboratory Safety
20 questions
Question 1: When planning a scientific investigation, identifying all potential hazards is the only safety measure required.
A. Ano
B. Ne
Explanation: Part of planning an investigation includes identifying all hazards and then thinking of ways to reduce the risks from those identified hazards. Both steps are crucial for ensuring safety, not just hazard identification.
Question 2: The size of a risk can be estimated by observing how many times something occurs within a large sample over a specific duration.
A. Ano
B. Ne
Explanation: The study materials state that the size of a risk can be estimated based on how many times something happens in a big sample over a given period.
Question 3: An activity is considered high risk if it involves a hazard that is very likely to cause harm and has serious consequences if it does.
A. Ano
B. Ne
Explanation: An activity is considered high risk if it involves a hazard that is very likely to cause harm, with serious consequences if it does.
Question 4: Placing a Bunsen burner on a heat-proof mat eliminates all fire hazards.
A. Ano
B. Ne
Explanation: Using a heat-proof mat with a Bunsen burner will reduce the risk of starting a fire, not eliminate all fire hazards.
Question 5: All microorganisms that may be encountered in science experiments can cause illness.
A. Ano
B. Ne
Explanation: The study materials state that 'some bacteria can make you ill,' indicating that not all microorganisms encountered in science experiments necessarily have the potential to cause illness.
