Which of the following should be readily accessible to all workers in case of a fire?

The right choice emphasizes the importance of having fire extinguishers and alarms readily accessible to all workers in the event of a fire. These safety items are crucial for immediate response in emergency situations. Fire extinguishers allow workers to act quickly to extinguish small fires and can prevent the fire from spreading, while alarms are vital for alerting everyone on site about the present danger, allowing for a quick and organized evacuation if necessary.

In a construction environment, where combustible materials and potential fire hazards are often present, ensuring that fire safety equipment is easily accessible can significantly enhance the safety of all personnel on site. This is in line with fire safety regulations and best practices, which dictate that workers should be able to reach these items without delay to mitigate the risks posed by fire.

In contrast, while construction blueprints, personal protective equipment, and tools and machinery manuals are important for daily operations and safety, they do not directly contribute to immediate fire response. Blueprints are typically used for construction planning, personal protective equipment is designed for worker safety against physical hazards, and manuals provide operational guidance for tools and machines, rather than addressing fire emergencies specifically.
