It occurred in a marketplace on the city's Lagos Island -- an enclave filled with highlyflammable structures built with wood and iron sheets, police said.
The family of New Zealand projectionist and film collector Jack Murtagh sent the highlyflammable prints to the organisation for safe keeping after his death in 1989.
According to the report, fridges and freezers built in recent years contain more plastic than older models, but the highlyflammable insulation is not separated from the parts of the appliance where a fire can start.
The situation is made all the worrisome because the hole is believed to be close to a well containing 1.5 million barrels of liquid butane, a highly volatile liquid that turns into a highlyflammable vapor upon release.
