Which of the following is NOT a component of a first aid kit?

The correct choice indicates that a fire extinguisher is not a component typically found in a first aid kit. First aid kits are designed to provide essential items necessary for immediate medical help in emergencies, such as treating minor injuries. Common components of first aid kits include adhesive bandages for covering cuts, antiseptic wipes for cleaning wounds, and CPR face shields for performing cardiopulmonary resuscitation safely.

A fire extinguisher, while critical for fire safety and emergencies related to fire, falls under a different category of safety equipment. It is not included in a first aid kit because its purpose is to extinguish fires rather than provide medical assistance for injuries. Understanding the distinction between first aid supplies and other safety equipment helps clarify the composition and intended use of each type of item.
