The correct answer is: A. Neon Lighting.
A fireman’s switch is a type of switch that is used to isolate electrical equipment from the mains supply in the event of a fire. It is typically located in a fire station or other emergency services facility.
Neon lighting is a type of lighting that uses neon gas to produce a bright, colorful light. It is often used in signs and advertising.
High pressure sodium lighting is a type of lighting that uses high pressure sodium gas to produce a bright, white light. It is often used in streetlights and parking lots.
Water features are decorative features that use water, such as fountains and waterfalls. They are often used in gardens and parks.
Hotel rooms are rooms that are rented out to guests by hotels. They typically have a bed, a dresser, a nightstand, and a television.
The reason why neon lighting requires a fireman’s switch is because it is a fire hazard. Neon lights can produce a lot of heat, and if they are not properly maintained, they can start a fire. A fireman’s switch can be used to quickly and easily turn off the power to a neon light in the event of a fire.
The other options are not fire hazards, and therefore do not require a fireman’s switch.
