Question 1
Store hazardous chemicals above eye level.
Correct Answer:
False
Explanation:
Storing hazardous chemicals at a height where they’re above eye level is not the recommended practice. Keeping them at or below eye level reduces the risk of eye exposure if a container leaks, spills, or breaks, and it makes handling and inspecting containers safer and quicker. Lower shelves also help prevent heavy or bulky containers from falling and causing injuries, and they make it easier to read labels and monitor storage conditions. In addition to height, place chemicals on sturdy, labeled shelves or in approved cabinets, keep incompatible substances apart, ensure containers are closed, and store according to any temperature or ventilation requirements.
Question 2
Which waste category includes needles, scalpels, and other sharp items contaminated with blood or body fluids?
Correct Answer:
Sharps
Explanation:
In healthcare and lab settings, items like needles and scalpels that are contaminated with blood or body fluids are categorized as sharps because they can pierce skin and cause infections. This category is designed to prevent injuries by using puncture‑resistant containers and proper disposal procedures specifically for any sharp object that could cut or puncture a bag, especially when biohazards are present. The other options refer to different types of waste: broken glass and plastics that may be chemically hazardous, general non-hazardous trash, or chemical waste rather than biological sharps. So, the sharps category is the correct fit for these contaminated sharp items.
Question 3
Which statement about conductivity and temperature is correct?
Correct Answer:
Conductivity Increases With Temperature.
Explanation:
Conductivity in liquids and electrolyte solutions generally rises as temperature increases. Higher temperature makes the solvent less viscous and gives ions more kinetic energy, so they move and diffuse more quickly under an electric field. This increased ion mobility translates to a greater charge transport per unit area, boosting conductivity. Temperature can also raise solubility for some solutes, adding more charge carriers. So the statement that conductivity increases with temperature best matches how most electrolytes behave. (Note: metals often show the opposite trend because electron scattering increases with temperature, but that’s a different context.)
Question 4
Liquids must be stored with secondary containment bins.
Correct Answer:
True
Explanation:
Storing liquids with secondary containment is a safety measure to catch spills or leaks and prevent them from reaching floors, drains, or the environment. The containment is designed to hold the full contents of the largest container stored and to resist the liquid’s chemical properties, so you’ll often see spill trays, containment pallets, or bermed basins used around cabinets and tanks. In practice, this protective setup is standard in labs and facilities to protect people, property, and the environment. Therefore, the statement is true.
Question 5
The Karl Fischer titrator is used to determine viscosity of liquids.
Correct Answer:
False
Explanation:
The main concept is that Karl Fischer titration assesses water content in a sample, not how thick or runny a liquid flows. The KF method uses a reagent that reacts specifically with water; in the volumetric approach the amount of titrant needed is proportional to the water present, and in the coulometric approach iodine is generated electrochemically and its quantity relates to the water content. Because this technique measures moisture, it does not determine viscosity, which is a property assessed with a viscometer or rheometer that observes flow under a given force. Therefore, the statement is false.
