Using a trampoline can be dangerous. Organized clubs and gyms usually have large safety end-decks with foam pads at each end, and spotters are placed alongside the trampoline to try to break the fall of any athlete who loses control and falls. In 1999, the U.S. Consumer Product Safety Commission estimated there were 100,000 hospital emergency room visits for trampoline injuries.

Due to the much larger numbers involved and lesser safety standards, the majority of injuries occur on privately owned home trampolines or in commercial trampoline facilities rather than organized gyms.Bouncing off a trampoline can result in a fall of 3–4 metres (10–13 ft) from the peak of a bounce to the ground or a fall into the suspension springs and frame. There has been an increase in the number of home trampolines in recent years and a corresponding increase in the number of injuries reported. Some medical organizations have suggested that the devices be banned from home use.

Authorities recommend that only one person should be allowed to jump at a time to avoid collisions and people being catapulted in an unexpected direction or higher than they expect. One of the most common sources of injury is when multiple users are bouncing on the trampoline at one time. More often than not, this situation leads to users bouncing into one another and thus becoming injured; many suffer broken bones as a result of landing badly after knocking into another user.

Another of the most common sources of serious injury is an attempt to perform somersaults without proper training. In some cases, people land on their neck or head, which can cause paralysis or even death.In an infamous incident in the 1960s, pole-vaulting champion Brian Sternberg became paralyzed from the neck down in a trampoline accident.

Danger can be reduced by burying the trampoline so the bed is closer to the surrounding surface to lessen falling distance, and padding that surrounding area. Pads over the spring and frame reduce the severity of impact injuries. Keeping the springs covered also reduces the risk of a limb falling between the gaps in the springs and the rest of the body falling off the trampoline.

Kits are available for home trampolines that provide a retaining net around the trampoline and prevent users from bouncing over the edge. The American Academy of Pediatrics states that there is no epidemiological evidence that these improve safety. The nets do prevent jumpers falling off the trampoline onto the ground, but these falls are not the most common source of injury. Multiple users bouncing in a netted trampoline can still be injured. Safety net enclosures have a larger benefit for safeguarding solo trampolinists, so long as they avoid falling on their head or neck.

Having some training in a gym may be beneficial in alerting people to possible hazards and provide techniques to avoid bad falls.

Family-oriented commercial areas in North America, such as shopping centres, carnivals, and so on, often include closed inflatable trampolines (CITs) as a children's attraction. These have safety nets on the sides to prevent injuries.

In order to make safe of the trampoline park, the owner should get enough skilled or professional staff to keep an eye on the customers who will come to play in the park, also need professional coach to teach them how to play with safe. And also the most important thing is to get a expereinced manufacturer for the trampoline park equipment , like SVIYA Group, who is the ASTM and TUV approved trampoline park manufacturer and supplier in China, since 1977 , all the equipment SVIYA make are accordingly to the ASTM and TUV standard, which is the most safety trampoline park.
