2. It is safe to eat or drink in the science lab.

True

False

Eating or drinking in a science lab is unsafe due to the presence of hazardous chemicals, biological agents, and potential contaminants. Consuming food or beverages can lead to accidental ingestion of toxic substances, which may cause serious health risks. Additionally, spills and residues from experiments can compromise the safety of consumables. Therefore, strict protocols prohibit eating and drinking in laboratory environments to ensure the safety and well-being of all individuals present.

3. WHMIS stands for Workplace Hazardous Materials Information System.

True

False

WHMIS is a comprehensive communication system designed to ensure that workers are informed about hazardous materials in the workplace. It provides essential information through labels, safety data sheets, and worker education and training programs. By standardizing the way hazardous materials are identified and communicated, WHMIS helps to protect workers from potential health risks and promotes a safer working environment. Therefore, stating that WHMIS stands for Workplace Hazardous Materials Information System is accurate.

9. Which of the following is the correct thing to do if a chemical splashes in your eyes?

Rub your eyes with a cloth

Rinse your eyes immediately at the eyewash station for 15 minutes

Wait to see if it gets better on its own

Put on your safety goggles after the splash

Rinsing your eyes immediately at the eyewash station for 15 minutes is crucial because it helps to flush out harmful chemicals, reducing the risk of serious injury or permanent damage to the eyes. Quick action is essential in minimizing exposure and mitigating potential harm. Waiting or rubbing the eyes can worsen the situation, as it may cause further irritation or spread the chemical. Safety goggles can prevent splashes but are not a remedy once exposure has occurred. Immediate rinsing is the most effective response to chemical splashes in the eyes.

10. What does the WHMIS symbol showing a flame over a circle represent?

Toxic material

Corrosive material

Oxidizing material

Flammable material

The WHMIS symbol featuring a flame over a circle indicates oxidizing materials, which can enhance the combustion of other substances. These materials are not necessarily flammable themselves but can cause or accelerate the burning of other materials, posing significant fire hazards. Recognizing this symbol is crucial for safety in handling and storage, as it helps prevent dangerous reactions that could occur when oxidizers come into contact with flammable or combustible substances.
