Qatar says it has begun a review of labour conditions for migrant workers after questions were raised about safety on construction sites, including projects for the 2022 World Cup.
The study comes as football's governing body Fifa meets in Zurich to discuss Qatar issues that include possibly moving the tournament to winter to avoid the searing summer heat.
Unions have warned that bad working conditions in the country could result in as many as 4,000 deaths before the tournament begins.
The Guardian has reported that 44 Nepalese workers died there between June 4 and August 8 this year.
Families of migrant workers already killed and injured on building sites in the Gulf state have called on Fifa to give the 2022 tournament to another country unless the Doha government can give guarantees on worker safety.
A statement issued by Qatar labour minister Ali Ahmed al-Kholeifi said an outside legal consultant was hired to lead an independent review of worker conditions and related issues.
Qatar and other Arab Gulf states bring in millions of migrant labourers, mostly from South Asia, for building projects.
Conditions have generally improved, but complaints persist about low wages and practices such as employers keeping workers' passports.
