Full Description
ASME A17.1-2013/CSA B44-13-one of ASME's most popular safety standards-addresses elevators, escalators, dumbwaiters, moving walks and material lifts. It provides requirements applying to the design, construction, installation, operation, testing, inspection, maintenance, alteration and repair of these conveyances.This living landmark has been defining safety in elevators, escalators and related equipment since 1921. A17.1 has been harmonized with CSA B44 to provide one comprehensive solution for jurisdictions throughout North America.
Major changes for the 2013 edition include:Requirements for wind turbine elevatorsRequirements for outsinde emergency elevatorsA new feature called Elevator Evacuation Operation (EEO) which allows for the use of elevators evacuationAn extensive update to the seismic requirementsUpdated requirements related to the maintenance control programA17.1 is to be used in conjunction with other volumes of ASME's A17 series of safety standards. Careful application of these A17 safety standards will help users to comply with applicable regulations within their jurisdictions, while achieving the operational and safety benefits to be gained from the many industry best-practices detailed within these volumes.
Intended for anyone engaged in the safety of elevators, escalators and related conveyances, including those responsible for: design, engineering and manufacture; installation, operation, testing, maintenance, alteration and repair; inspection; plans, contracts, administration, insurance and liability; property, facilities and plant management; and emergency response.
