Smell of Gas

Natural gas is one of the safest sources of energy available. Natural gas is non-toxic, colorless, tasteless and odorless. NSTAR Gas and other gas companies add an odor to gas so you will know if natural gas is escaping.

If you smell gas:

Put out all open flames. Don’t light matches or lighters, and don’t attempt to light your appliance.
Don’t touch electric switches, thermostats or appliance controls; they may cause sparks.
Leave the premises and call NSTAR Gas at 800-592-2000.

NSTAR Gas provides 24-hour emergency service every day of the year.
