What kind of suggestion are you making?
Technical such as dimensions or application of the standard
What should we change?
Change #1 -
21.1.1.A. Point on Braking Mechanism
Current Draft: "They have tracks .....plus braking."
Change #2
21.1.1. - Current Draft: (Implied only as a "wheeled device")
Change #3
Point on Comfort and Support Features
Current Draft: (Not mentioned)
Change #4
Point on Manufacturing Quality and Warranty
Current Draft: (Not mentioned)
What should we change it to?
Change #1
Proposed Change: "They are equipped with continuous track or belt systems that use SELF-BRAKING, friction-based mechanisms to ensure a controlled, safe descent downstairs. The system should require no manual brake operation by the operator, allowing them to focus on steering and stability."
Change #2 -
Proposed Change: "The chair must incorporate a 4-point safety harness to securely restrain the occupant's torso and a hammock-style seat that cradles the occupant, preventing any forward or lateral slippage during descent. A flat seat is unacceptable for safety."
Change #3
Proposed Change: "The chair should include padded headrest, adjustable armrests and a stable, adjustable footrest to provide full-body support and comfort for the occupant during evacuation."
Change #4
Proposed Change: "Devices must be manufactured to the highest safety and durability standards, with preference given to manufacturers with rigorous national safety certifications FDA, ISO, (e.g., UK, USA, Germany, manufacturers renowned for this specialty of Evacuation Chairs). Purchasing specifications should require a full lifetime warranty on the frame and mechanism."
Why should we change it?
Change #1 -
Reason for Change: The term "plus braking" is vague and implies an optional or separate manual brake, which is not standard and could be dangerous if misunderstood or misused in a high-stress evacuation. Global best practice relies on automatic, friction-based systems that provide constant, predictable control without operator intervention, maximizing safety and ease of use.
Change #2-
Reason for Change: A flat seat with only a lap belt presents a severe risk of the occupant sliding out or experiencing "submarining" under the belt. A 4-point harness distributes force and prevents forward slump, while a hammock seat provides crucial lateral and rearward containment. This combination is essential for safety, security, and occupant comfort, reducing panic and injury risk.
Change #3
Reason for Change: Comfort is directly tied to safety and cooperation. A comfortable occupant is more likely to remain calm and still. Proper arm and foot support prevent limbs from dangling, which could cause injury, interfere with the tracks, or unbalance the chair. These features also show respect for the occupant's dignity during a stressful event.
Change #4
Reason for Change: Evacuation chairs are life-critical safety devices that may sit unused for years but must perform perfectly in an emergency. A lifetime warranty ensures the manufacturer stands behind the product's longevity and durability, guaranteeing parts and support for its entire service life. Sourcing from established, high-regulation markets mitigates the risk of substandard materials or construction, ensuring a reliable product that will last.
