编者按：在城市规模越来越大，建筑物越建越高的情况下，再谈大型单层建筑的火灾危险性有无必要？究竞有没有必要在这种建筑里安装消防报警及水喷淋系统？──当英国国会于今年7月份立法规定零售商场（单层）也必须安装消防水喷淋系统时，有许多人提出了以上疑问。吉姆·丹尼博 Editor’s note: In the case of an ever-increasing size of the city and the higher the building’s height, why is it necessary to discuss the fire hazard of large single-storey buildings? Is there a need to install fire alarms and sprinkler systems in such buildings? ─ ─ When the U.K. legislature enacted in July this year that the retail market (single floor) must also install a fire sprinkler system, many people raised the above questions.
