(HealthDay News) -- Some parents may falsely assume that all playground equipment is safe.

The Nemours Foundation says certain types of equipment should have parents thinking twice about letting their children use them. These include:

• Swings with animal figures.
• Gliding swings meant for more than one child.
• Ropes for swinging. They may unravel or pose a strangulation hazard.
• Exercise rings (resembling those used by gymnasts) or trapeze bars.
• Monkey bars.
• Trampolines.
