ITOGON, Benguet: Poor ventilation in the work place again resulted in the death of another miner who choked to death inside a mine tunnel in this mining, a belated report by the Benguet police said. Miner Feliciano Oydoc Lis-ig, a native of Sabangan town in Mt. Province was found dead, eight hours after he and co-miners entered for work at an usok (Iluko term for bending over to enter a small, wet, cramped and gaseous portal). Benguet police director Senior Supt. Florante Camuyot said Lis-ig is one among the long list of contractual miners who choked to death inside poorly-ventilated and oxygen unaided underground mining operations in this so-called gold rush district.
