IS 17462 Part 8 : 2020Safety Rules for the Construction and Installation of Lifts — Lifts for the Transport of Persons and Goods — Part 8: Vandal Resistant Lifts

IS 17462:2020 Part 8 is the Indian Standard (BIS) for safety rules for the construction and installation of lifts — lifts for the transport of persons and goods — part 8: vandal resistant lifts. This standard specifies the safety rules for the construction and installation of special evacuation lifts intended for use by persons with disabilities during an emergency. It outlines supplementary requirements to standard passenger lifts, focusing on fire protection of the lift well and lobbies, secondary power supply, two-way communication systems, and specific car dimensions to ensure safe evacuation.
Specifies additional safety rules for lifts intended to be installed in buildings where vandalism is a risk.
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
Practical Notes
! This standard is crucial for high-rise buildings and must be read in conjunction with the National Building Code (Part 4: Fire and Life Safety).
! The evacuation lift is distinct from a 'Fireman's Lift', though they can be a combined unit if all requirements of both standards are met.
! Effective implementation requires close coordination between the architect, fire consultant, MEP engineer, and the lift manufacturer to ensure all protective measures and system interfaces are correctly designed and installed.

Covers similar safety objectives for electric lifts but follows a different code structure and has distinct technical requirements.

Key Differences
≠IS 17462 explicitly references the National Building Code (NBC) of India for fire resistance requirements of landing doors and hoistway construction, which may impose specific national criteria not detailed in the base EN 81-20 standard.
≠The Indian standard requires adherence to Indian Standards for electrical installations, wiring, and earthing (e.g., IS 732, IS 3043), which constitute national deviations from the CENELEC/IEC standards referenced in EN 81-20.
≠While EN 81-77 addresses seismic conditions, IS 17462 incorporates requirements based on India's specific seismic zoning maps and codes (like IS 1893), leading to potentially different design calculations and component specifications for lifts in earthquake-prone areas.
≠IS 17462 may specify or reference Indian Standards for materials (e.g., steel grades, concrete mix), whereas EN 81-20 references corresponding European or ISO material standards. The performance outcomes are the same, but the certification path differs.
Key Similarities
≈Both standards mandate Unintended Car Movement Protection (UCMP) to detect and stop the car if it moves away from the landing with the doors open, a critical modern safety feature.
≈The requirements for safety spaces for maintenance personnel are identical, specifying minimum refuge volumes and postures (e.g., 0.4m x 0.5m x 2.0m for upright) on the car roof and in the pit.
≈Both IS 17462 and EN 81-20 require a full-height, non-contact light curtain or similar device to prevent landing doors from closing on a person or object, replacing the older 'magic eye' concept.
≈The strength and testing requirements for car and landing doors, including the soft and hard pendulum impact tests to ensure containment and robustness, are directly adopted from EN 81-20.
≈The principles for overspeed detection and the mandatory use of a progressive type safety gear for lifts with a rated speed exceeding 0.63 m/s are fully harmonized between the two standards.

Key Clauses
Clause 5.2 - Protection of the evacuation lift environment against fire, smoke and water
What is the primary purpose of an evacuation lift under this code?+
To provide a safe and reliable means of vertical evacuation for persons with disabilities during an emergency, particularly a fire.
What are the minimum internal dimensions for an evacuation lift car?+
1100 mm (width) x 2100 mm (depth), to accommodate a standard stretcher and attendants. (Table 1)
Is a separate power supply required?+
Yes, a secondary, protected power supply is mandatory. It must automatically take over within 60 seconds and run the lift for a minimum of 2 hours. (Clause 5.5)
What kind of communication system is needed?+
A two-way communication system is required, connecting the lift car to the building's fire service control room or a designated control point. (Clause 5.4)
