Safety Recommendations for Using a Residential Generator

Posted on
25/4/2025

Generators have long been essential devices that help households maintain a proactive power supply during unexpected outages. However, alongside their benefits, improper use of a generator can pose serious risks, affecting both lives and property.

With over 40 years of experience in the generator field, in this article, Huu Toan will share important guidelines that users need to follow to operate a residential generator safely and effectively.

1. Absolutely Do Not Use a Generator Indoors or in Enclosed Spaces

When in operation, a generator produces Carbon Monoxide (CO)—a colorless, odorless, and extremely dangerous gas if inhaled. Placing the machine in enclosed spaces such as a basement, storage room, or garage can lead to gas accumulation and pose a serious threat to the health of users.

Always operate the equipment in a well-ventilated area. If you experience symptoms such as dizziness, nausea, or headaches, leave the area immediately, get fresh air, and open doors and windows for ventilation.

2. Avoid Using the Generator in the Rain or in Humid Conditions

Rain, humid air, and damp conditions are all electrically conductive environments. Operating a generator in these conditions creates a high risk of electrical conduction or surface discharge, which can cause short circuits, fires, or electric shock accidents.

The generator should be placed on a flat, dry surface in a well-ventilated area, and it should be protected from direct contact with water to ensure safe operation.

3. Do Not Connect the Generator Directly to a Wall Outlet

Improperly connecting a generator can cause the electrical current to back-feed into the power grid, which can damage electrical appliances and even pose a fatal risk to users.

If you require a regular backup power source from a generator, the safest solution is to install an Automatic Transfer Switch (ATS) to ensure safety.

4. Store Fuel Properly

The fuels used to run generators, such as gasoline and diesel, are highly flammable. Therefore, they must be stored in a cool, dry, and well-ventilated place, away from ignition sources and flammable materials. Fuel should also be stored outside of living areas to minimize the risk of fire or explosion.

5. Purchase Genuine Generators with a Clear Origin and Brand

Choosing a generator should not be based solely on price; you must carefully consider its origin and the brand's reputation. Prioritize genuine products, as they not only ensure stable operating quality but also come with clear warranty policies and professional after-sales service—giving you peace of mind for long-term use and saving you from unnecessary repair costs.
