That's a really thoughtful question, and it's something more people should consider when choosing outdoor equipment for their homes. To answer you directly: no, a well-designed outdoor trash can should not have any dangerous sharp edges.
Modern trash cans, especially those designed for residential use, are built with safety and durability in mind. Manufacturers typically use materials like polyethylene or galvanized steel, which can be molded and formed with rounded, smooth edges. This isn't just for safety; it also makes the cans more robust and resistant to cracking.
You might find sharper edges on older, more worn-out metal cans or on cheaper, low-quality models where the plastic molding isn't as refined. These can potentially pose a snag or scratch risk, especially if you have curious children or are maneuvering the can in a tight space like a garage.
When you're shopping for a new can, run your hand along the lid's rim, the handles, and the base. You should feel smooth, rolled, or rounded contours. This simple check is a great way to ensure you're bringing a safe product into your home environment. Ultimately, your peace of mind is important, and opting for a can from a reputable brand that prioritizes user-friendly design is the best way to eliminate this worry entirely.
