It is with heavy hearts that we share in the sadness of this grave tragedy that afflicted Rio on Sunday. To AAIV and all fans of Il Volo in Brazil and South America, please know our thoughts are with you. My current boss was born in Rio, Brazil, so I, too, have a connection to this. 🙁
There is a very nice and in-depth article published by the NY Times, of which I am providing the link: https://www.nytimes.com/2018/09/03/world/americas/brazil-museum-fire.html
It said the museum did not have a fire suppression system, but was due to get a $5 million dollar grant/overhaul soon, which included a fire suppression system.

National Museum of Brazil
Local name: Museu Nacional
Location: Rio de Janeiro, Brazil
The National Museum is the oldest scientific institution of Brazil and one of the largest museums of natural history and anthropology in the Americas. The museum is located inside the Quinta da Boa Vista park, in the city of Rio de Janeiro, and is installed in the Paço de São Cristóvão. The palace served as residence for the Portuguese Royal Family between 1808 and 1821, housed the Brazilian Imperial Family between 1822 and 1889, and also hosted the Republican Constituent Assembly from 1889 to 1891, before being assigned to the use of the museum in 1892.
