Everyone Working In A Laboratory Should Pass This Safety Quiz

The correct answer is "National Fire Protection Agency." NFPA is an acronym that stands for National Fire Protection Agency. This organization is responsible for developing and publishing fire safety codes and standards to minimize the risk of fire hazards and promote fire safety practices.

Eating or drinking in the lab is not safe because it can lead to contamination of the samples or experiments being conducted. Food or drinks may contain substances that can react with chemicals or interfere with the accuracy of measurements. Additionally, spills or accidents can occur, leading to potential hazards such as slips, falls, or damage to equipment. Therefore, it is important to follow lab safety protocols and refrain from consuming food or drinks in the lab.

Open shoes and shorts are not allowed in the lab because skin exposed to chemicals can cause injuries.

If a chemical comes in contact with your skin or eyes, it is important to immediately wash it off with water. This is because water can help dilute and remove the chemical from your skin or eyes, reducing the risk of further damage or injury. Waiting for the teacher to tell you what to do may waste precious time and potentially worsen the situation. Therefore, taking immediate action by washing with water is the most appropriate response in this situation.

The correct answer is "Twice carefully." This implies that you should read the labels on two separate occasions, and each time you should do so with attention and caution. Reading the labels twice helps ensure that you have a thorough understanding of the information provided, reducing the chances of any mistakes or misunderstandings. By emphasizing the need to read them carefully, the answer suggests that simply glancing at the labels or skimming through them may not be sufficient.

In the event of an accident, it is important to notify your instructor. They are responsible for your safety and well-being during the activity or situation, and they need to be informed so that appropriate actions can be taken. Your instructor will have the knowledge and experience to handle the situation effectively, ensuring that you receive the necessary help and support. Notifying your best friend or partner may not be sufficient as they may not have the necessary expertise or resources to assist you in an emergency situation.

In a lab setting, it is generally not allowed to taste anything. Lab environments are controlled and regulated to ensure safety, and tasting substances can pose health risks or lead to contamination. Lab materials may be toxic, corrosive, or otherwise harmful if ingested. Therefore, it is important to follow safety protocols and refrain from tasting any substances in the lab.

When mixing acid and water, it is important to pour the acid into the water rather than the other way around. This is because pouring water into acid can cause a violent reaction, resulting in the acid splashing out and potentially causing harm. On the other hand, pouring acid into water allows for better control and dilution of the acid, reducing the risk of a dangerous reaction.

Wearing contact lenses during a lad can cause injuries and blindness. This is because lads involve physical activities that may result in the contact lenses getting dislodged or scratched, leading to eye injuries. Additionally, lads often expose the eyes to dust, dirt, and other particles that can get trapped under the lenses, causing irritation and potential infections. Therefore, it is recommended to avoid wearing contact lenses during lads to ensure the safety and health of the eyes.

After using a chemical, it is important to properly dispose of it to prevent any harm to the environment or human health. In the case of this question, the correct answer is to drain it down the drain. This implies that the chemical should be safely disposed of by pouring it down the drain, following any local regulations or guidelines for the specific chemical. This ensures that the chemical is properly treated and does not contaminate water sources or cause harm to living organisms.
