Can You Use a Generator on a Deck or Balcony?

Generator Safety on Elevated Areas

Generators should be used in well-ventilated areas, away from living spaces, and windows. Elevated areas like decks and balconies pose significant risks due to the potential for carbon monoxide (CO) to accumulate and be trapped. CO is a colorless, odorless gas that can be deadly in high concentrations.

Ventilation Requirements

To use a generator safely on a deck or balcony, you need to ensure adequate ventilation. This involves creating a path for CO to escape and not recirculate back into the living space. A general rule of thumb is to provide 10 to 20 square inches of ventilation per 1,000 watts of generator power. For a 5,000-watt generator, you would need approximately 50 to 100 square inches of ventilation area.

Safe Placement Strategies

If you must use a generator on a deck or balcony, consider the following strategies for safe placement:

• Position the generator at least 10 feet away from any windows or doors to living spaces.
• Use a CO detector in the living space, especially if windows are open or ventilation is poor.
• Ensure the generator is installed on a level, stable surface and securely tied down.
• Consider using a generator enclosure or cover with built-in ventilation to help reduce CO risks.
• Follow the manufacturer’s instructions for proper installation and operation of the generator.
