1 NEW DELHI, India (CNN) - Indian Prime Minister Atal Behari Vajpayee’s ruling Bharatiya Janata Party has conceded defeat in parliamentary elections in a stunning voting upset that should see the return of the Nehru-Gandhi dynasty to power.2 Vajpayee - who called the election six months early - is also expected to resign later Thursday, BJP President Venkaiah Naldu said.3 The move follows a stronger than anticipated showing from the main Congress party headed by Italian born-Sonia Gandhi.4 Though the party won’t be able to form a majority, the stage has now been set for Gandhi to become the next prime minister in the world’s biggest democracy.5 Counting is continuing but unofficial trends by major TV stations and early results have Congress leading the BJP and likely to win over 200 seats in the 543-member lower house, or Lok Sabha.6 The immediate result of the vote count is likely to be a hung parliament, with no party gaining a clear majority of 272 seats.7 Senior Congress officials say they are confident they will be able to form a government with the help of left-leaning parties, CNN New Delhi Bureau Chief Satinder Bindra reports.8 "We have not got the mandate of the people, we have decided to sit in the opposition," BJP President Naidu announced Thursday.9 Gandhi, 57, is the widow of Rajiv who was assassinated in 1991 by Sri Lanka’s Tamil Tiger rebels. Rajiv is the son of former prime minister Indira Gandhi and grandson of India’s first premier, Jawaharlal Nehru.10 India’s last female leader was Indira Gandhi, who was assassinated while in power in 1984.11 Gandhi, and her popular children Rahul and Priyanka, have revitalized the Congress party, leading it to defy opinion polls that only weeks ago suggested they had no hope of faring well in this election. Vajpayee called the early election in a seemingly unassailable position - boosted by a booming economy and also a strengthening peace process with neighbor and arch-rival, Pakistan.12 Congress party officials said they would keep pursuing a peace dialogue with Pakistan, while Islamabad - which had been hopeful the BJP-led ruling coalition would be reelected - says it is hopeful talks will continue.13 The 79-year-old Vajpayee had sought a fourth term as prime minister, arguing he had earned another five years in office because he had turned the economy around.14 Early opinion polls had indicated that Vajpayee s ruling Hindu nationalist-led coalition would easily win a new five-year term.15 In contrast, the Congress party and its allies have been championing the nation’s poor, which the party says has been left out of India’s new found prosperity.16 While Indians have traditionally voted on party, caste and religious lines, this election has been fought on bread-and-butter issues such as jobs, prosperity, water and electricity. Which of the following is NOT mentioned in the passage.

×日，B石化分公司双苯厂硝基苯精馏塔发生爆炸，造成8人死亡，60人受伤，直接经济损失6908万元，并引发江水污染事件。国务院事故及事件调查组认定，中石油B石化分公司双苯厂“12·13”爆炸事故和江水污染事件是一起特大生产安全责任事故和特别重大水污染责任事件。 1．爆炸事故的直接原因是：硝基苯精制岗位处操作人员违反操作规程，在停止粗硝基苯进料后，未关闭预热器蒸汽阀门，导致预热器内物料气化；恢复硝基苯精制单元生产时，再次违反操作规程，先打开了热器蒸汽阀门加热，后启动粗硝基苯进料泵进料，引起进入预热器的物料突沸并发生剧烈振动，使预热器及管线的法兰松动、密封失效，空气吸入系统，由于摩擦、静电等原因，导致硝基苯精馏塔发生爆炸，并引发其他装置、设施连续爆炸。 2．爆炸事故的主要原因是：双苯厂对安全生产管理重视不够、对存在的安全隐患整改不力，安全生产管理制度存在漏洞，劳动组织管理存在缺陷。 3．污染事件的直接原因是：双苯厂没有事故状态下防止受污染的“清净下水”流入江水的措施，爆炸事故发生后，未能及时采取有效措施，防止泄漏出来的部分物料和循环水及抢救事故现场消防水与残余物料的混合物流入江里。 4．污染事件的主要原因： 一是B分公司及双苯厂对可能生的事故会引发江水污染问题没有进行深入研究，有关应急预案有重大缺失。 二是该市事故应急救援指挥部对水污染估计不足，重视不够，未提出防控措施和要求。 三是中国石油天然气集团公司和股份公司对环境保护工作重视不够，对B分公司环保工作中存在的问题失察，对水污染估计不足，重视不够，未能及时督促采取措施。 四是该市环保局没有及时向事故应急救援指挥部建议采取措施。 五是省环保局对水污染问题重视不够，没有按照有关规定全面、准确地报告水污染程度。 六是环保总局在事件初期对可能生的严重后果估计不足，重视不够，没有及时提出妥善处置意见。 根据以上场景，回答下列问题： 危险化学品单位应当制定本单位事故应急救援预案，配备应急救援人员和必要的应急救援器材、设备，并定期组织演。危险化学品事故应急救援预案应当报( )备案。
