Natural gas is colorless and can only be detected by an odor added to the natural gas which produces a distinct, strong smell. The WMGLD periodically sends a card to its customers to familiarize them with the smell. If you think you have a gas leak, leave the home immediately. DO NOT TOUCH anything which could create a spark: i.e. turning on a light switch, using the telephone, etc. Telephone the WMGLD at (781) 246-6363 from a neighbor’s home.
