Explanation:

To solve these lab safety fill - in - the - blanks, we rely on standard lab safety knowledge:

For the "In Case of Accident" section:

Step 1: Analyze the second note

In a lab accident, when there is broken glass (like from a broken beaker or test tube), we need to sweep up the broken glass and then dispose of it as per the teacher's instructions. So the first blank is "broken glass" and the second is "dispose".

Step 2: Analyze the third note

For cleaning up spills, we should do it immediately to prevent further harm. When an acid is spilled, we can neutralize it with a base (this is based on the acid - base neutralization reaction in chemistry). So the first blank here is "immediately" and the second is "neutralize".

Step 3: Analyze the fourth note

Any injuries (or accidents/hazards) that occur in the lab, such as cuts, burns, etc., should be reported to the teacher immediately. So the blank is "injuries (or accidents/hazards)".

For the "How do you handle a chemical spill on your skin?" question:

We should flush the affected area with plenty of water (usually for at least 15 minutes) and then report to the teacher.

For the "No ____ in the lab!" question (from the top part):

Common lab safety rules prohibit eating (or drinking) in the lab to prevent contamination and accidental ingestion of chemicals.

Final Answers (filling in the blanks):

• In Case of Accident - Note 2: broken glass; dispose
• In Case of Accident - Note 3: immediately; neutralize
• In Case of Accident - Note 4: injuries (or accidents/hazards)
• Chemical spill on skin: Flush the affected area with plenty of water and report to the teacher.
• No ____ in the lab: eating (or drinking)
