Natural Gas Safety Natural gas has an excellent safety record as a form of energy used in the home. You can keep your natural gas service safe by becoming familiar with the information and instructions listed in this section.
Natural gas is lighter than air, non-toxic and contains no poisonous ingredients.
Breathing natural gas is not harmful as long as there is an adequate supply of fresh air to breathe along with it. Natural gas by itself will not burn. Combustion or explosion can occur only when there is a mixture of gas and air containing between five and 15 percent of natural gas. Children, the disabled and the elderly are at the highest risk of being scalded. See the instruction manual before setting the temperature on the water heater.
