Which of the following is not listed as a utility to shut off in safety procedures?

• A. Electrical
• B. Gas
• C. Water
• D. Telephone

Answer: (D)

Shutting off utilities in safety procedures centers on removing sources of immediate physical hazards. Electricity is cut to prevent shock and arcing, gas is shut off to stop leaks and potential explosions, and water is turned off to prevent flooding and control contamination or firefighting needs. A telephone line isn’t a hazard source to be controlled in that way; it’s a communication tool that helps responders coordinate and summon help, so it isn’t treated as a utility to shut off. That’s why the option not listed as a utility to shut off is the telephone.
