In April 2013, Rana Plaza, an eight-storey building on the outskirts of Dhaka, the capital of Bangladesh, collapsed.
More than 1,000 people died and many others were injured.
The building contained five garment factories which manufactured clothes for well-known international brands.
It was the worst industrial disaster in Bangladesh's history.
Parul Akhter, a sewing machinist who survived the collapse, talks to Dan Hardoon.
