According to former employees, emerald miners working for Canada’s Fura Gems, have been working in unsafe conditions. Managers fail to provide basic safety equipment such as masks and safety glasses. According to Fura managers, these allegations are false. The firm claims to take worker safety seriously, and has also stated that this specific location is in the process of adopting more safety standards.
