GB 4943.23-2012 Information technology equipment—Safety—Part 23:Large data storage equipment

The requirements of this part of GB 4943 apply to information technology equipment with built-in data storage systems and dangerous moving parts. These data storage systems are typically large enough to allow a person to fully enter, and they also include similar large equipment that allows an entire limb or head to enter the area with dangerous moving parts. The requirements of this part are an addition to the relevant requirements of IEC 60950-1. Storage components are typically characterized by a three-dimensional space of 0.75 m3 or more for movement.
These devices should be installed in restricted access areas, such as data centers. The exceptions mentioned in 2.1.3 and 4.5.4 of IEC 60950-1:2005, as noted in Note 1, do not apply to this part.
Note 1: Examples of equipment included in this part: automatic mass storage and retrieval systems used with dangerous moving parts for processing recorded media (such as tape drives, film cartridges, optical discs) and similar functions.
This part does not apply to equipment that does not contain dangerous moving parts itself, such as robot equipment installed in industrial environments.
Note 2: For robot equipment in industrial environments, see the relevant standards GB 5226.1, GB 5226.3, and GB 11291.1.

GB/Z 28598-2012 Study of the use of lifts for evacuation during an emergency

This guidance technical document focuses on studying the main risks associated with the use of elevators to evacuate people in various emergency situations.
The types of emergencies in the buildings or their neighboring buildings studied include fires, floods, earthquakes, explosions, biological attacks or chemical corrosion, gas leaks, lightning strikes, or storms.
The purpose of this guidance technical document is to provide a clear method related to the design of elevators and buildings, so as to determine whether the given design can use elevators within an acceptable safety level.
This guidance technical document does not consider all the risks of all buildings, nor does it consider that all elevators have all the functions mentioned. It is the responsibility of the building designers to determine the events that are prone to occur in the building according to the importance, function, floor area ratio, condition, geographical location, use, scale, etc. of the given building.
Determining whether an elevator can be used as a safe evacuation tool for a given building is not and cannot be the responsibility of the elevator manufacturers. Making this decision should be the responsibility of other relevant personnel. Elevator manufacturers can only provide some suggestions about the designed capabilities of a specific elevator or the condition of the elevator in a particular situation.
The method adopted in this report can be applied to buildings of any size, new and existing, but it has been proven difficult and uneconomical to apply it to existing buildings in practice.
