Retailers who sourced garments from Tazreen Fashions in Bangladesh are again being urged to pay "full and fair" compensation to the victims of the factory fire – more than one year after the blaze killed at least 112 people.

Human Rights Watch on Monday (16 December) said survivors are still suffering from their injuries, as well as loss of income, and have not received adequate compensation.

"Many retailers with production at the factory have not yet helped a group of very poor workers and their families," said Brad Adams, the group's Asia director.

The call follows similar demands from other campaign groups and unions last month to mark the anniversary of the fire on 24 November.

Meaningful compensation, the human rights group said, has so far only been provided by the Bangladesh Garment Manufacturers and Exporters Association (BGMEA), the Bangladesh government, retailer C&A and Hong Kong-based Li & Fung.

According to calculations by the Clean Clothes Campaign (CCC), long-term compensation for the injured and families of the deceased should be at least US$5.7m, which could be shared between the factory owner, retailers, the BGMEA, and the government.

"With proper oversight and inspections, this tragedy could have been avoided," Adams added. "Western companies can no longer avoid the fact that people were killed and injured because they were providing cheap labour in unsafe conditions."
