The correct answer is A. safety goggles.
Safety goggles are often considered the minimum requirement for personal protection in a laboratory setting because they protect the eyes from hazardous substances, flying debris, and chemical splashes. While gloves, fire blankets, and aprons are also important for safety, goggles are usually mandatory to safeguard one of the most vulnerable areas during lab work.
The correct answer is B. chemical splash goggles.
Chemical splash goggles are specifically designed to protect the eyes and face from hazardous liquids, chemicals, and splashes, making them the best choice for handling chemicals in a lab. Safety glasses provide some eye protection but do not offer the same level of coverage as goggles, especially against splashes. An apron and gloves are important for other types of protection, but they do not protect the eyes and face directly.
The correct answer is C. locate and use an eye/face wash.
If you get chemicals in your eyes, you should immediately locate an eye/face wash station and flush your eyes with water for at least 15 minutes. This helps to dilute and remove the chemical from your eyes. It's important to seek medical attention afterward, even if you believe the exposure was minor. Going home, putting on safety goggles after the fact, or wiping chemicals off your face are not appropriate actions and may worsen the situation.
The correct answer is C. fire blanket.
A fire blanket is specifically designed to smother flames and can be used to extinguish a fire that is on a person by wrapping it around them to cut off the oxygen supply. While a fire extinguisher can be used for many types of fires, it's generally not suitable for extinguishing fires on people and can sometimes make the situation worse. An apron and eye/face wash are not appropriate for putting out a fire on a person. If a fire blanket is not available, the person should be encouraged to stop, drop, and roll to extinguish the flames.
The correct answer is C. I should wash my hands with soap and water.
Before conducting an investigation in a laboratory, it is important to wash your hands to ensure that any contaminants are removed and to maintain a clean working environment. While it's also a good practice to check that all equipment is safe to use (your answer D is important as well), the act of washing hands is a fundamental safety protocol to prevent contamination and ensure personal hygiene.
Asking for permission to eat or drink (B) is also a good practice, but washing hands is a paramount step prior to handling any materials or equipment in the lab. Taking medicine for allergies (A) is generally a personal health decision and does not relate directly to laboratory safety practices.
