Three workers (30, 35, and unknown age) died while another was hospitalised after a suspected gas leak at a lubricant-manufacturing factory. The accident occurred around 8:30 pm when employees entered a chamber for routine maintenance and were exposed to toxic fumes. The hospitalised worker was stable. Company manager said one of the workers lost consciousness, prompting two colleagues to rush to his aid. All three were soon overwhelmed by the fumes. The trio was taken to a hospital where they were declared dead.
