Chemical contamination incident at DRC coltan mine kills eleven, triggers UN emergency protocol
Eleven workers at an artisanal coltan mine in the Kivu province of the Democratic Republic of Congo died on 13 July after exposure to an unidentified chemical agent. It was released while they were digging into a previously uncharted underground deposit. On 14 July the United Nations Environment Programme (UNEP) activated its hazardous-materials emergency coordination mechanism. It sent a joint assessment team with the World Health Organization (WHO) to identify the agent and assess how far contamination has spread. Early field reports describe symptoms consistent with organophosphate or heavy-metal poisoning, but definitive spectrographic analysis is still pending. About 1,200 workers at nearby mining sites have been evacuated, and a multi-agency cordon now extends 3 kilometres around the area. If you have people in resource extraction in sub-Saharan Africa or other geologically uncharted areas, carry out a hazardous-materials site assessment before deployment and make sure first-responder capability is on site. Staff without hazardous-environment training or the right PPE are not adequately protected where underground hazards cannot be identified in advance.
