Most sore throats result from viral infections, usually colds, but possibly influenza. In children or adults who were not immunized, the measles, chickenpox or whooping cough can cause a sore throat. Sometimes, a canker sore or fever blister forms in the throat, causing intense pain upon swallowing.
Many vehicles available today come with fuel pump shut-off switches. These devices are essentially circuit breakers that sit inside you car's airbag control module's inertia switch, which is supposed to trigger when the vehicle comes to a sudden stop.
The shut-off valves must be easily accessible in an emergency. If there were a fire, oxygen would accelerate its spread, so quickly cutting off the gas supply is critical. Placing the medical gas shut-off valves behind a door or other building feature is prohibited (EC.02.05.09, EP 3).
