Standard Specification for Window Fall Prevention Devices With Emergency Escape (Egress) Release Mechanisms
ABSTRACT
This specification establishes the installation, safety, performance, and labeling requirements for devices intended to address the risk of injury and death associated with accidental falls from windows by children five years old and younger. It applies to window fall prevention devices that are to be used on any window, including those that are designated for emergency escape (egress) and rescue (ingress). It is, however, not intended to meet the unique requirements of the Americans with Disabilities Act (ADA).
SCOPE
1.1 This specification establishes requirements for devices intended to address the risk of injury and death associated with accidental falls through open windows by children five years old and younger.
1.2 This specification is not intended to meet the unique requirements of Americans With Disabilities Act (ADA).
1.3 This specification applies to window fall prevention devices, including window opening control devices, window fall prevention screens, and fall prevention window guards, that are to be used on operable windows, including those that are designated for emergency escape (egress) and rescue (ingress).
Note 1: A separate safety specification, Safety Specification F2006, covers window fall prevention devices for non-emergency escape (egress) and rescue (ingress) windows in installations more than 75 ft6 (23 m) above ground level in multiple family dwelling buildings since windows at these heights are beyond the reach of rescue ladders currently in use.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 This standard does not purport to address all safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

INTRODUCTION
This consumer safety specification addresses window fall prevention devices that protect against
potential falls by children aged five years and under through open windows. Window fall prevention
devices currently available include window opening control devices, window fall prevention screens,
and some types of window guards. These devices use different strategies to prevent children from
falling through open windows. Window opening control devices restrict the size of the open area of
the window so that it is too small for a young child to fall through. They do this by allowing the
window opening to be set at a predetermined position. Window fall prevention screens and fall
prevention window guards provide a barrier to prevent a child from falling through an open window.
A special study by the U.S. Consumer Product Safety Commission (CPSC) indicates that young
children are at risk of death and serious injury from falls through open windows. Children aged five
and younger account for a higher percentage of window fall fatalities and injuries.
Windowfallpreventiondevicesusuallydifferinpurposeandapplicationfromsecurity/burglarbars.
The general purpose of a window fall prevention device is to prevent a child age five or younger from
falling through an open window. The general purpose of a security bar is to prevent unlawful entry
through a window. Generally window fall prevention devices and security bars are two separate
devices. However, a security bar could be used as a fall prevention device if it meets the requirements
of this specification.
The CPSC has advised caregivers to open windows less than 4 in. when children are present as one
means to prevent child falls through open windows.Window opening control devices provide a means
that the window, when opened in an initial operation, will satisfy the CPSC recommendation to open
less than 4 in. The 4-in. dimension is drawn from related building codes and standards for openings
in guardrail assemblies, and is universally accepted as the appropriate dimension to prevent a child
frompassingthroughbalconyorguardrailingsystems.Anadditionaloperationisrequiredtoopenthe
window further. The additional operation must be performed without the use of keys, tools, or special
knowledge. Security from forced entry is not within the scope of this standard and is not the intended
function of any of the devices referred to herein.
The intent of this update to the standard is to improve the clarity of performance and labeling
requirements and to reorganize the sections such that the general requirements, performance tests,
safety information, labeling requirements, and installation instructions are separated by device type.

Window fall prevention devices usually differ in purpose and application from security/burglar bars.

rescue requirements of the applicable building code.
4.5 Window fall prevention screens or fall prevention window guard devices shall be designed with release mechanisms to
allow for emergency escape (egress) without the need for special tools or special knowledge.
4.5.1 Operation of emergency escape (egress) mechanisms shall be accomplished with a minimum amount of effort from the
inside of the building, whether the window fall prevention screen and fall prevention window guard device is mounted inside or
outside the building.
4.5.2 Release of the emergency escape (egress) mechanism shall require no more than 15 lbf (66 N) of force.
4.5.3 To protect against inadvertent operation by a young child, the emergency escape (egress) release mechanism(s) shall
