Final answer:
The correct answer includes all the safety items listed: first aid kit, fire extinguisher, and reflective vest, as each serves an important role in emergency situations and ensuring personal safety.
Step-by-step explanation:
When considering optional safety equipment that may include emergency phone numbers, tire chains, the answer to what else might be included is indeed all of the above: a first aid kit, a fire extinguisher, and a reflective vest. Each item serves a specific purpose in ensuring safety. A first aid kit is essential for treating minor injuries on the spot. A fire extinguisher can be crucial in putting out small fires before they escalate. A reflective vest ensures that the wearer is visible to others, particularly in emergency situations or poor visibility conditions. It's important to know where these items are located and to ensure they are maintained and ready for use. In addition to these items, personal protective equipment such as safety goggles, hearing protectors like ear plugs, safety helmets, and safety belts are vital, as they provide protection from various risks encountered during different activities.
