Excerpts or circulars regarding specific amendments made in the 2021 update. Code of Practice (805) - EMSD

The Code of Practice on the Design and Construction of Lifts and Escalators (2021 Edition), often referred to as the "Design Code," is a mandatory regulatory document issued by the Electrical and Mechanical Services Department (EMSD) of the Hong Kong Government. It sets the technical standards, safety rules, and procedural requirements for the installation and commissioning of vertical transportation systems in the region. Core Purpose and Effective Date

The 2021 Edition was gazetted on December 31, 2021, and officially became effective on October 1, 2022. Its primary goal is to enhance the safety and reliability of new installations by harmonizing local requirements with the latest international standards, such as the European standard EN 115-1:2017 for escalators. Key Technical Updates in the 2021 Edition Government portals (e

Adoption of EN 115-1:2017: A major portion of the amendments focused on Section E Part 4, incorporating international escalator standards adjusted for local needs. Enhanced Escalator Safety:

Drive Chain Replacement: Drive chains for escalators with a vertical rise exceeding 15 meters must now be replaced at intervals not exceeding six years.

Brake Testing: Rigorous testing of the braking system is required at least every five years.

Anti-climbing Measures: Specific requirements for shelter walls (at least 1800mm high) and balustrade clearances (max 75mm) to prevent falls, particularly for escalators with a rise greater than 15 meters.

Lift Design and Stability: All components and structural members must conform to established principles of applied mechanics and strength of materials to ensure they are free from defects and suitable for their intended operating environment.

Emergency Communication: New requirements for acknowledgement lights in lifts for persons with disabilities, which must blink to notify users that an emergency call is active. Code of Practice (805) - EMSD
