The nine-storey Rana Plaza complex collapsed one day after cracks were seen appearing in the structure on the outskirts of Dhaka, in one of the world’s worst industrial disasters.
The tragedy highlighted appalling safety and other conditions for thousands of workers making clothes for Western retailers, and piled pressure on top brands to clean up Bangladesh’s textile industry, the world’s second largest after China.
Dozens of factories shut down or were ordered to shift to more stable buildings after the disaster, while almost all factories were found to have fire and other safety faults.
