CÁC CẤP ĐỘ TRÀN DẦU
(TIERED RESPONSE TO OIL SPILLS)
Tier One_Cấp cơ sở (<20 tons)
Small, operational-type spills that typically occur at a company’s own facilities (e.g. jetties or terminals), and as a consequence of its own activities. The operator would typically provide its own resources to respond to the spill, i.e. “the spill may be handled by the spiller”.
Tier Two_Cấp khu vực (<500 tons)
A medium-sized spill that typically occurs within public or multi-user facilities, and which typically is associated with shipping accidents in ports or harbours. Personnel and equipment resources would be pooled from other companies and the industry, with local government agencies acting as coordinators.
Tier Three_Cấp quốc gia (>1000 tons)
A large spill with potentially catastrophic consequences, that typically results from spillages at sea from tankers and offshore platforms. Substantial resources and support from local, national and international stockpiles would be mobilized.
