Final answer:
A member should not use mobile phones upon locating a bomb due to the risk of detonation from the electronic signals. Additionally, safety precautions include using hands-free devices and avoiding cell phone use in confined spaces.
Step-by-step explanation:
Upon locating a bomb, a member shall not use C) Mobile phones. Mobile phones can potentially detonate a bomb due to the electric signals they emit. Therefore, it is critical for safety reasons to avoid their use near potential explosive devices.
There are several precautions that can be taken to minimize the risks associated with mobile phones and other electronic devices in the vicinity of a suspected bomb. First, using hands-free devices helps to decrease radiation to the head while also keeping the phone itself away from the body. Additionally, avoiding the use of cell phones in confined spaces like cars without an external antenna is advisable, as the signals can be stronger and potentially more hazardous in such environments.
The use of other electronic devices that emit signals, such as radios or flashlights with electronic switches, should also be under proper consideration when near a suspected explosive device.
