Residential emergency generator safety tips

Sizing a generator is an important part of understanding how to shop for a generator, but there is another crucial point to consider – generator safety. Ensuring that you take proper care when using a generator to power your home is important since electrical generators can be hazardous if not used properly. Here are a few generator safety tips to follow:

Be sure to place a portable generator at least 15 feet from any structure.
Generators should only be used in well-ventilated areas to protect from carbon monoxide output.
Generators should be kept dry and operate only on dry surfaces to prevent electrocution.
When refilling a generator, be sure to let it cool down completely to avoid starting a fire. Store fuel in a safe place, away from sparks or flames.
Only use approved, heavy duty extension cords to power your appliances. Do not overload the generator with more wattage draw than it can manage.

The most important thing to remember about selecting the right type of generator is to plan ahead: for a winter storm, prepare for a hurricane or a blackout/brownout. During a power outage, people rush to the store to grab a generator, so stores may be out of the generator size you need or might not give you enough time to have the generator safely installed in your home. Prevent installation issues by purchasing and installing a generator long before you’re in need of one.
