Police statistics have shown that automobile antitheft devices reduce the risk of car theft, but a statistical study of automobile theft by the automobile insurance industry claims that cars equipped with antitheft devices are, paradoxically, more likely to be stolen than cars that are not so equipped:
Which one of the following, if true, does the most to resolve the apparent paradox ？（）

A．Owners of stolen cars almost invariably report the theft immediately to the police but tend to delay notifying their insurance company, in the hope that the vehicle will be recovered.

B．Most cars that are stolen are not equipped with antitheft devices, and most cars that are equipped with antitheft devices are not stolen.

C．The most common automobile antitheft devices are audible alarms, which typically produce ten false alarms for every actual attempted theft.

D．Automobile owners who have particularly theft-prone cars and live in areas of greatest incidence of car theft are those who are most likely to have antitheft devices installed.

E．Most automobile thefts are the work of professional thieves against whose efforts antitheft devices offer scant protection.

2008年，G淀粉公司雇佣临时人员把仓库改造成第三生产车间。该车间为长80m、宽50m、高15m的桁架砖混结构建筑，分成打包间和产品暂存间。打包间用7m高砖墙与暂存间分隔。打包间内有打包机8台、振动筛8台。振动筛安装在6m高的二层钢制平台上，振动筛内筛子采用木质框架，筛子四角与振动筛用铁质螺栓连接。振动筛开关和电动机为防爆电器设备。

2010年3月10日10时30分，当班班长甲发现4号打包机故障，二层钢制平台滞留了大量淀粉，正散落到打包间地面。甲关停4号打包机，并向车间主任报告。14时，甲带领10名工人到二层钢制平台清理淀粉。一部分工人使用扫把、铁锹等工具清理平台上的淀粉，装包后，通过楼梯把成包淀粉滚落到打包车间地面，或从二层平台直接将淀粉包扔到打包间地面。另一部分工人用铁制扳手卸下筛子，用铁棍敲打清理筛子上的淀粉。

当清理工作进行到15时10分时，突然发生燃爆，而后发生多次爆炸，打包间一片火海，第三生产车间厂房的四面墙体全部倒塌。事发时，打包间和暂存问分别有作业人员19人和79人。事故导致18人死亡、7人重伤、38人轻伤。

事故发生后，当地政府立即成立现场救援指挥部。搜救人员多次进入车间搜救，利用切割机、生命探测仪、液压顶杆、起重气垫等装备进行救援，并在厂房周边同时用消防水枪降温，防止再次燃爆。

根据以上场景，回答下列问题：

指出G淀粉公司为预防此类事故再次发生应采取的安全技术措施和安全管理措施。
