The Swiss canton of Valais has banned the use of pyrotechnic devices in all indoor public places after a devastating fire in a bar on New Year’s Eve killed 40 people and injured 116 others.

Authorities said each victim would receive an emergency payment of 10,000 francs ($12,500; £9,200) and a fund had been set up to collect donations.

The canton of Geneva has also announced a ban on fireworks in indoor venues – days after Vaud became the first of Switzerland’s 26 regions to take such a decision.

The fire at Le Constellation bar in the Crans-Montana ski resort is believed to have started when fireworks from champagne bottles ignited acoustic foam padding on the ceiling.

Authorities admitted the pub had not had a safety inspection in five years.

Two partners in Le Constallation, French couple Jacques Moretti and Jessica Moretti, have been charged with manslaughter, negligent bodily harm and negligent arson.

Jacques Moretti was initially detained for 90 days. His wife had to hand over her passport and report to the police every day.

The news that the pub had not been inspected for five years shocked the families of the victims, most of whom were young, eight of them under 16.

Many of the injured had severe burns. Eighty people remain in hospitals in Switzerland and other European countries.

An online platform has been launched to receive testimonies related to the disaster, a lawyer representing the victims’ families said on Tuesday.

“This move is intended to facilitate the investigation for the benefit of the victims,” ​​rather than replace the official investigation, Roman Jordan said.

Among the dead was a waitress who was shown wearing a helmet and holding a champagne bottle with a sparkler in her hand as the ceiling caught fire.

She is widely believed to be 24-year-old Cyane Panine, from Port-Sète in southeastern France, and is said to have a close relationship with the bar manager.

Her family released a statement saying: “Regardless of the outcome of the investigation, the young woman followed her employer’s instructions. She did what the general manager asked her to do. There was nothing unusual. The young employee was not held responsible.”
