The safety of large amusement rides, such as roller coasters, will be boosted after China's leading quality watchdog on Tuesday unveiled a set of rules to improve supervision.

Companies that manufacture, install, renovate or repair large rides will be liable for the quality of equipment and machinery, according to a regulation announced by the General Administration of Quality Supervision, Inspection and Quarantine.

Operating companies will be responsible for the safety of the rides, the rules said.

Operators must apply to inspection authorities for regular safety checks in a timely manner, according to the regulation.

They should also make emergency response plans for each ride and hold an emergency rescue drill at least once a year.

The rides refer to those with a designed speed or 2 meters per second or quicker, or those at heights of no less than 2 meters, according to the rules.

Accidents occasionally take place in China. On Sunday, three people were seriously hurt after being thrown out of a spinning machine in an amusement park in the city of Xi'an, northwestern China's Shaanxi Province.

The regulation will become effective on Jan. 1, 2014.
