Avoid using a telephone during a thunderstorm. There might be a slight chance of electric
shock from lightning.
Do not use a telephone in the vicinity of a gas leak. Under certain circumstances, a spark
may be created when the adapter is plugged into the power outlet, or when the handset is
replaced in its cradle. This is a common event associated with the closing of any electrical
circuit. The user should not plug the phone into a power outlet, and should not put a charged
handset into the cradle, if the phone is located in an environment containing concentrations
of flammable or flame-supporting gases, unless there is adequate ventilation. A spark in such
an environment could create a fire or explosion. Such environments might include: medical
use of oxygen without adequate ventilation; industrial gases (cleaning solvents; gasoline
vapors; etc.); a leak of natural gas; etc.
