Investigators were first allowed to enter the main building Monday, but it is still off-limits to researchers. Instead, some scientists were focusing attention on an annex on the site, where vertebrate specimens were housed. The fire didn’t reach the area, but it caused the electricity to fail, threatening some artifacts, said Marcelo Wexler, a researcher in the vertebrate department.
“We have animals that need to be frozen, and they were rotting without electricity,” Wexler said.
In a sign of the enormity of the task ahead, a museum security guard created a stir when he arrived on the scene carrying a document he said belonged to the institution that he had found across the street.
“I came here to give it back. I am sure there is much more that flew around,” Felipe Silva told a group of journalists who crowded in to see the document, which he put in a clear plastic folder.
Even as efforts turned to searching the rubble, firefighters were still occasionally directing water at the building, where some embers were still burning. Eduardo Rosse, a fire official, said that was normal for a blaze of this size.
Luiz Fernando Dias Duarte, a museum official, said Monday that anything held in the main building was probably destroyed, and Serejo told the G1 news portal that 90 percent of the collection may have been destroyed.
But on Tuesday, she held out some hope, telling journalists that staff members were “reasonably optimistic about finding some more items inside.”
She added that UNESCO, the U.N.’s cultural agency, had offered financial and technical assistance. French and Egyptian officials also have offered help. The museum was home to Egyptian artifacts, and Egypt’s ministries of foreign affairs and antiquities have expressed concern over the fate of those objects.
With the cause still under investigation, many already have begun to fix blame, saying years of government neglect left the museum underfunded and unsafe.
Roberto Leher, rector of the Federal University of Rio de Janeiro, to which the museum was linked, said it was well known that the building was vulnerable to fire and in need of extensive repair. In fact, the institution had recently secured approval for nearly $5 million for a planned renovation, including an upgrade of the fire-prevention system, but the money had not yet been disbursed.
On Monday, government officials promised $2.4 million to shore up the building and promised to rebuild the museum.
