It is convenient for fighting and evacuation, and a circular fire lane should be set up. With the accelerating pace of urbanization, urban land is increasingly tight, which promotes the construction of high-rise buildings. Many high-rise buildings, due to poor consideration of fire prevention design and other reasons, have many congenital hidden dangers, and fires occur from time to time, causing heavy losses. In order to create convenient conditions for fire fighting and rescue work and ensure the safety of buildings, circular fire lanes should be set up around high-rise buildings. However, regardless of the size of the building, it is indeed difficult to require the circular fire lanes. Lanes can be set up along the two long sides of the building. In order to prevent the collapse of building components in case of fire from affecting the normal operation of the fire lane, the distance between the fire lane and the outer wall should be 5m. There should be no trees, overhead pipelines, etc. that hinder the operation of climbing fire engines between fire lanes and high-rise buildings. If the total length of the building exceeds 220m, a fire lane shall be set up to pass through the building. There is no inner courtyard in the building, there are ring fire lanes around it, and fire engines crossing the building need to be set up. Q: An L-shaped high-rise building has a total length of about 170m, a length of 120m along the street, and a length of 50m along the inner street (residential road). Do you want to set up fire lanes crossing the building? A: The relevant provisions of the "Construction Regulations" and "High Regulations" consider that there is no restriction on the length of the two wings on the premise of meeting the requirements of fire fighting and evacuation. The building only needs to set up a pedestrian passageway connecting the street and the inner courtyard at the part over 80m along the street, and there is no need to set up a fire lane. In the planning of fire lanes, in addition to the relevant provisions of the "Construction Regulations" and "High Regulations", attention should also be paid to香港SARS疫潮过后，人们终于从阴霾中走出来。脑外科医生程至美（吴启华饰）突然得知前女友的死讯，情绪崩溃，极度自责抑郁。法医岑雅晴（黎姿饰）伴其左右，鼓励他重新建立信心。急症室医生黎国柱（林保怡饰）结束了与女友的恋情，却卷入与骨科医生叶淘（吴美珩饰）及见习医生曾淑淇（廖碧儿饰）的三角恋中。不幸感染SARS的心脏科医生林敏智（陈豪饰）留下后遗症，为保全名声而隐瞒病情，却令病情日益恶化。妇产科医生万安生（邵美琪饰）与急症科医生向众仁（曹永廉饰）正计划共同生活，然而却因护士戴玉莹（姚嘉妮饰）的介入而面临一场情感考验。This is the disassembled evaporator, and the edge is covered with residues (cold air is generated from here and blown into the car through the blower).
