Outdoor garbage containers must be placed on what type of surface?

Outdoor garbage containers must be placed on a smooth, durable, non-absorbent surface to ensure proper sanitation and hygiene. This type of surface prevents liquid waste from being absorbed, which can lead to unpleasant odors, attract pests, and create an unhygienic environment. Smooth surfaces facilitate easier cleaning and maintenance, which is crucial in areas where garbage is stored to minimize the risk of contamination and maintain a safe, sanitary environment for both workers and the public.

Placing garbage containers on other surfaces, such as grass, soil, or rough concrete, can lead to complications like the collection of moisture and debris, making routine cleaning more difficult and allowing for potential leakage that could harm the environment.
