Question

q 3. the student pictured below is about to go into a chemistry lab. 1. what lab safety procedure(s) is she not following? options: wear close fitting or short sleeves (checkbox), tie back long hair (checkbox), wear safety goggles (checkbox) (image of a student with long hair, no safety goggles, and a shirt with sleeves)

Explanation:

1. For "Tie back long hair": The student has long hair that is not tied back. In a chemistry lab, long hair should be tied back to prevent it from catching fire or getting into chemicals.
2. For "Wear safety goggles": The student is not wearing safety goggles. Safety goggles are essential in a chemistry lab to protect the eyes from chemical splashes, fumes, or flying debris.
3. "Wear close fitting or short sleeves": The student's sleeves are not close - fitting or short (she has long - sleeved - like appearance? Wait, actually her sleeves seem to be short? Wait, no, looking at the image, maybe the key ones are the hair and goggles. Wait, re - evaluating: The student has long hair not tied back, and no safety goggles. The "wear close fitting or short sleeves" - her sleeves look short, maybe that's okay. So the two she is not following are "Tie back long hair" and "Wear safety goggles". But let's check again. In a chemistry lab, standard safety procedures: tie back long hair, wear safety goggles, wear appropriate clothing (close - fitting or short sleeves to prevent sleeves from catching fire or getting into chemicals). Wait, the student's sleeves: the image shows a short - sleeved top? Wait, maybe the main ones are hair and goggles. So the procedures she is not following are "Tie back long hair" and "Wear safety goggles".

Answer:

• Tie back long hair (the student's long hair is loose, not tied back, which is a safety hazard in a lab as hair can catch fire or interfere with experiments).
• Wear safety goggles (the student is not wearing goggles, which are necessary to protect eyes from chemical splashes, fumes, etc.).
