Nearly 500 Bangladeshi garment workers have been burned to death in preventable fires in the last five years. Among the worst industrial disasters there in recent years: 84 garment workers — mostly young girls — died in a blaze inside a locked factory in February of 2006. Twenty-one people died at a factory that supplied orders for H&M in February of 2010. (The same factory had had a deadly blaze the previous October. Yet another fire broke out the following April.) Smaller, less deadly fires happen even more regularly.
