put your nose directly over the container.
wave your hand gently over the container toward your nose (wafting).

Explanation:

Step1: Analyze lab - safety clothing

Dangling jewelry can get caught on equipment or spill chemicals, so it's not appropriate for lab safety. Closed - toe shoes protect feet, lab aprons protect clothing, and safety goggles protect eyes.

Step2: Analyze volume conversion

We know that 1 liter = 1000 milliliters. To convert 2.5 liters to milliliters, we use the formula $V_{mL}=V_{L}\times1000$. So, $2.5\times1000 = 2500$ mL.

Step3: Analyze odor - detection method

Putting your nose directly over the container of strong - smelling chemicals is dangerous as it can cause inhalation of large amounts of harmful vapors. Wafting is the correct method to detect odor.

Answer:

1. A. Dangling jewelry
2. A. 2500 mL
3. B. Wave your hand gently over the container toward your nose (wafting)
