Abstract: Dow’s fire and explosion index method is adopted to carry out safety evaluation of the methanol storage tanks of certain company in Nantong. And the risk factors including fire explosion index, radius and areas of exposed zones of methanol tank unit before and after the safety allowance were obtained. The evaluation results showed that the evaluation unit of methanol tank had a “very high” level of hazard before compensation, but the hazards can be reduced to a “relatively light” level after taking safety compensation measures. This indicates that safety compensation measures are necessary, and also provides a theoretical basis for the prevention of accident risks and the management of methanol tank units
