REVISED BSI STANDARDS

摘要

BSI, the business standards company, has revised BS 7273-4:2015 Code of Practice for the operation of fire protection measures - Part 4: Actuation of release mechanisms for doors. It was developed using collaborative input from the fire and safety industry with such organisations as the Fire Industry Association (FIA), Fire Protection Association and National Landlords Association offering guidance. Fire doors are typically designed to be kept closed at all times so that fire and heat are contained and their spread minimised. This is achieved through use of well-engineered fire doors. However, on occasion they may be held open to facilitate convenience and/ or accessibility around a building and, in this situation, mechanisms to hold them open should follow BS 7273-4.
