Romanian authorities say they have confiscated 38 tons of pyrotechnics in the weeks ahead of New Year celebrations, two months after fireworks set off a nightclub fire which killed 63 people.

The interior ministry said Wednesday it had stepped up checks in December, confiscating pyrotechnics from clubs and other venues.

The use of pyrotechnics and fireworks, both inside and outdoors is common in Romania. Safety regulations can be lax.

A fire broke out at the Colectiv nightclub in Bucharest on Oct. 30 after a spark from fireworks intended for outdoor use ignited foam decor, sending panicked revelers to a single exit door.

Since then, safety measures have been tightened up in Romania. Some clubs temporarily closed to improve fire safety standards.
