ACS CP Professional Ethics & Safety Standards 1 — Questions and Answers

Question 1: What is a key element of professional ethics in chemistry?

Honesty in data reporting (Correct answer)
Exaggerating results
Ignoring peer review
Withholding negative results

Correct answer: Honesty in data reporting

Professional ethics in chemistry, and science in general, demand integrity and transparency in all research activities. Honesty in data reporting is paramount, ensuring that results are presented accurately, without manipulation, fabrication, or falsification, to maintain scientific credibility and public trust.

Question 2: Which organization publishes chemical safety guidelines?

FDA
ACS (Correct answer)
USDA
NHTSA

Correct answer: ACS

The American Chemical Society (ACS) is a leading professional organization for chemists, and it plays a significant role in promoting safety in chemical laboratories and industries. The ACS publishes comprehensive safety guidelines, best practices, and educational resources to ensure the safe handling and use of chemicals.

Question 3: What is the purpose of an SDS (Safety Data Sheet)?

To advertise chemicals
To list chemical prices
To provide hazard and safety information (Correct answer)
To replace lab instructions

Correct answer: To provide hazard and safety information

A Safety Data Sheet (SDS), formerly known as a Material Safety Data Sheet (MSDS), is a crucial document that provides comprehensive information about a chemical substance or mixture. It details potential hazards, safe handling procedures, emergency control measures, and other vital safety information for users.

Question 4: Which of the following is a correct lab safety practice?

Wearing sandals
Wearing PPE (Correct answer)
Eating in the lab
Using damaged equipment

Correct answer: Wearing PPE

Wearing Personal Protective Equipment (PPE) such as safety goggles, lab coats, and appropriate gloves is a fundamental lab safety practice. PPE creates a barrier between the user and potential hazards, significantly reducing the risk of exposure to chemicals, splashes, and other physical dangers.

Question 5: What should be done immediately after a chemical spill?

Ignore it
Report and contain the spill (Correct answer)
Leave the area
Wipe it with paper towels only

Correct answer: Report and contain the spill

In the event of a chemical spill, the immediate and correct action is to report it to a supervisor or designated safety personnel and then, if safe to do so, contain the spill using appropriate materials like absorbent pads. This prevents further spread, minimizes exposure, and ensures proper cleanup procedures are followed.

Question 6: Which of the following best promotes ethical collaboration?

Claiming sole authorship
Properly crediting contributors (Correct answer)
Hiding sources
Omitting minor contributors

Correct answer: Properly crediting contributors

Ethical collaboration in any scientific field requires acknowledging the contributions of all individuals involved in a project. Properly crediting contributors through authorship, acknowledgments, or citations ensures fairness, recognizes intellectual property, and upholds the principles of academic integrity.

Question 7: What should you always check before starting a chemical experiment?

Only the lab schedule
The chemical's hazard information (Correct answer)
Experiment time only
Room temperature

Correct answer: The chemical's hazard information

Before starting any chemical experiment, it is essential to thoroughly review the hazard information for all chemicals involved, typically found in their Safety Data Sheets (SDS). Understanding the risks, such as flammability, corrosivity, or toxicity, allows for appropriate safety precautions and emergency preparedness.

Question 8: Which symbol indicates a substance is corrosive?

Flame
Corrosion (Correct answer)
Health hazard
Explosive

Correct answer: Corrosion

The 'Corrosion' pictogram (a hand and a surface being corroded) is a globally recognized GHS (Globally Harmonized System) symbol indicating that a substance can cause skin corrosion/burns, serious eye damage, or is corrosive to metals. This symbol warns users of the chemical's ability to destroy living tissue or material upon contact.

Question 9: What is the first action in case of a fire in the lab?

Try to extinguish it alone
Pull the fire alarm (Correct answer)
Run for the exit immediately without warning
Finish the experiment first

Correct answer: Pull the fire alarm

In case of a fire in the lab, the absolute first action is to pull the fire alarm to alert everyone in the building and initiate emergency protocols. This ensures that others are warned and that professional help (fire department) is summoned immediately, prioritizing human safety over property.
