Relatives of five African men crushed by a wall in 2016 say they would have answers by now if they had been white and British, the BBC has been told.
All five, from The Gambia and Senegal, died when 15ft of concrete fell on them at a scrap metal plant in Birmingham.
A spokesman for their families said the two-year wait for an inquest, due to take place next month, had “taken a toll” on those left behind.
The health and safety watchdog’s investigation has yet to conclude.
Ousmane Kaba Diabi, 39, who was from Senegal, Alimamo Kinteh Jammeh, 45, Bangally Tunkara Dukureh, 55, Saibo Sumbundu Sillah, 42, and Muhamadou Jagana Jagana, 49, died in the incident. The men were all Spanish citizens with dual Gambian nationality.
They had come to the UK to work, some with their families, and were employed alongside other Gambians at the scrap metal plant in Nechells.
At the time, Shredmet Ltd, which deals with more than 500,000 tonnes of scrap metal each year, said the wall had been in place for more than two years and had not been subject to any damage that could have caused the collapse.
The site was closed for six weeks after the incident.
No criminal prosecutions have been brought over the deaths.
