Identifying Hazards in Your Shed and Garage: How to Create a Safer Environment

The garage and shed provide convenient places to store items and equipment you use in and around the home. From tools and outdoor implements to powerful cleaning chemicals, the shelves of a garage tend to accumulate a wide variety of items. Even a well-organized garage can be a dangerous place due to the hazardous chemicals it contains. As you maintain an orderly garage or shed, follow recommendations for storage, use, and disposal of these products. Proper maintenance of hazardous chemicals helps make the garage and the environment safer places.

A wide variety of chemicals are common to a garage or shed. Anyone who maintains a yard or a garden will probably store fertilizer and herbicides in this location. These products can be toxic to humans and animals. Other typical products that sit on garage and shed shelves include paint, solvents, and gasoline. These products are flammable, so they require careful storage to prevent fire risks. For safety, keep these products in their original containers away from any sources of flame. Store oily rags carefully to prevent fire. A sealed metal container is the safest place to keep oily rags. Other automotive products, such as antifreeze, windshield washer fluid, and brake fluid, also contain dangerous chemicals and should be stored carefully.

The safest way to maintain chemicals in the garage is to only purchase what you will be able to use up. This will eliminate the need for disposing of hazardous chemicals. If you can't use a product before it becomes unusable, consider giving it to someone else who can use it. Some municipalities organize donation centers to enable residents to donate hazardous products they don't need. If you do need to throw away products that contain chemicals, always follow local ordinances for safe disposal. Cities often provide collection points for citizens to drop off their hazardous products for safe disposal.
