ULC CAN/ULC 590:2019 (R2024) Standard for Design, Installation, Inspection, Testing and Maintenance of Safety Way Guidance System

PREFACE

This is the First Edition of CAN/ULC 590, Standard for the Design, Installation, Inspection, Testing and Maintenance of Safety Way Guidance Systems.

This Edition of the Standard has been formally approved by the ULC Standards Committee on Life Safety Accessory Devices.

This Standard has been developed in compliance with the requirements of SCC for accreditation of a Standards Development Organization.

Only metric SI units of measurement are used in this Standard. If a value for measurement is followed by a value in other units in parentheses, the second value may be approximate. The first stated value is the requirement.

Annexes A and B, identified as Normative, form a mandatory part of this Standard.

In Canada, there are two official languages, English and French. All safety warnings must be in French and English. Attention is drawn to the possibility that some Canadian authorities may require additional markings and/or installation instructions to be in both official languages.

Attention is drawn to the possibility that some of the elements of this Canadian standard may be the subject of patent rights. ULC Standards shall not be held responsible for identifying any or all such patent rights.

Requests for interpretation of this Standard should be sent to ULC Standards. The requests should be worded in such a manner as to permit a “yes” or “no” answer based on the literal text of the requirement concerned.

This CAN/ULC 590 Standard is under continuous maintenance, whereby each revision is approved in compliance with the requirements of SCC for accreditation of a Standards Development Organization. In the event that no revisions are issued for a period of four years from the date of publication, action to revise, reaffirm, or withdraw the standard shall be initiated.

Comments or proposals for revisions on any part of the Standard may be submitted at any time. Proposals should be submitted via a Proposal Request in the Collaborative Standards Development System (CSDS) at https://csds.ul.com.

This Standard is intended to be used for conformity assessment.

Scope

1.1 This Standard covers the principles governing the design and application of visual components used to create a safety way guidance system (SWGS) and requirements for the installation, inspection, testing and maintenance of SWGS.

1.2 This Standard contains general principles valid both for electrically powered and for

photoluminescent components. Special information which is related to the type of component is given to assist in defining the environment of use, choice of material, layout, installation and maintenance of SWGS.

NOTE: This Standard recognizes that a safety way guidance systems may have additional features or functions differing from those detailed in these requirements, if the features or functions enhance the life safety of the occupants of the building.

1.3 This Standard does not provide guidance for egress safety evaluations. Applications with different risks to the occupants typically require different layouts and types of SWGS. SWGS is to be reviewed by qualified persons.

1.4 This Standard also does not include the special considerations of possible tactile or audible components of SWGS, nor does it include requirements for high mounted components of the emergency egress / emergency means of egress lighting, especially the design and application of emergency egress / emergency means of egress lighting.

1.5 The installation of components not covered by these requirements shall be in accordance with good engineering practice and manufacturer's published installation instructions.
