Answer 1

The correct labeling required on every portable fire extinguisher is 'c. letters and/or symbols that identify the type of fire for which it is intended,' to ensure users know which types of fires they can safely combat with the extinguisher.

Step-by-step explanation:

The question is related to safety protocols within a laboratory setting, specifically concerning portable fire extinguishers and their labeling. Every portable fire extinguisher must provide essential information for safe and effective use, especially during emergencies. According to safety standards, fire extinguishers should have labels or other forms of marking that clearly communicate the types of fires they are suitable to combat.

The labeling includes letters and/or symbols that identify the type of fire for which the extinguisher is intended. It is mandated that these identifiers be present so that users can quickly determine if the extinguisher is appropriate for the fire they are attempting to control or extinguish. Therefore, the correct answer to the student's question is 'c. letters and/or symbols that identify the type of fire for which it is intended.'
