Explanation:

• For the first question: When chemicals splash into eyes, the immediate priority is to flush the eyes with water to minimize damage. Disposing of the reagent, putting away the lab book, or cleaning the bench top are not the first - aid steps for eye exposure.
• For the second question: Carrying scalpels in a paper towel (to prevent cuts) or in a small tray (for containment) are safe methods. Wearing exam gloves is for protection during use, not specifically for carrying. And students are allowed to carry them with proper precautions.
• For the third question: Backpacks, cell phones, and unnecessary books can contaminate or cause accidents in the lab, so none of these are routinely allowed.
• For the fourth question: In a lab, food and beverage consumption is generally not allowed. However, if the instructor permits (after proper risk assessment), it might be allowed. Holidays, handling bacterial broths, or during computer labs (unless specifically permitted) are not valid reasons for allowing food and beverage consumption.

Answer:

• First question: A. Immediately go to the nearest sink and flush your eyes with water.
• Second question: A. in a paper towel, B. in a small tray.
• Third question: D. none of these.
• Fourth question: B. permitted if instructor allows.
