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.

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.
Window fall prevention devices usually differ in purpose and application from security/burglar bars.
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
from passing through balcony or guard railing systems. An additional operation is required to open the
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.

5. Performance Tests
5.1 Preparing Specimen for Testing:
5.1.1 Window fall prevention guards shall be extended to the maximum width and height as specified by the manufacturer.
Extended fall prevention window guards and window fall prevention screens shall be mounted in a test frame or holder assembly
using installation techniques that are representative of the same mounting devices and techniques as recommended in the
manufacturer’s installation instructions. All testing shall be done with the fall prevention window guard or window fall prevention
screen device placed so that its inside (exposed) surfaces are subjected to the applied forces under 5.2 and 5.3.3.
5.1.2 The test supports shall be located in such a manner that they are contacting only the test frame and not providing any
support directly to the installed window fall prevention device.
5.1.3 Use the same window fall prevention device specimen for all performance tests (5.2 – 5.4). Test following the order
indicated by the performance test number sequencing.
5.2 Static Load (Hang) Test:
5.2.1 A load distribution device capable of exerting a 60 lb (267 N) force shall be used.
5.2.2 This test shall be performed for each different type of component in the window fall prevention device (vertical bars,
horizontal bars, webbing, or other graspable components, etc.).
5.2.3 With the window fall prevention device installed as specified in 5.1.1, suspend the load distribution device from each of
the individual component part members of the window fall prevention device (for example, hang the weight from a horizontal bar
component or from a member or opening of webbing, or other graspable component) in a manner that simulates the anticipated
load representative of a child hanging from any individual part of the window fall prevention device.
5.2.4 Apply a vertical force of 60 lb on the component at any representative point within or on the device. Reasoning statement:
To simulate the weight of a five year old child hanging from any component/part of the device.

F2090 − 13
5.2.5 Once the test weight is removed, the tested specimen is inspected to determine that the window fall prevention device shall
prohibit the free passage of a 4.0 in. (102 mm) diameter rigid sphere through or around it anywhere in the window opening (as
required by applicable codes for that jurisdiction).
5.2.6 The latching or locking device of release mechanism shall remain engaged and operative after testing.
5.3 Pendulum Test:
5.3.1 Rationale—This test is based on subjecting the window fall prevention screen or fall prevention window guard device to
100 ft-lb (136 J) of energy. This is the energy that would be generated by a 50-lb (22.7-kg) child (95th percentile 5-year-old) falling
directly onto the window fall prevention device from a height of 2 ft or running directly into the window fall prevention device
at a speed of 11.4 ft/s (3.48 m/s) (approximately 50th percentile 6-year-old sprint speed; 6 years is the youngest age for which data
are available).
NOTE 3—100 ft-lb is a reasonably stringent criterion. If, while bouncing on a bed for instance, the child fell against the window fall prevention device,
it is not likely that all of the energy from such a fall would be directed straight into the window fall prevention device, as it is in the testing situation.
In addition, the window fall prevention device is not intended to protect against an intentional all-out effort on the part of the child to run through the
window fall prevention device.
5.3.2 Test Objective—The test determines the fall prevention device’s resistance to allowing an opening to develop that would
permit a child to pass through after being impacted. The fall prevention device must not have an opening larger than the maximum
space as prescribed by 4.1. If such a space is found after the test, this will constitute failure of the device.
5.3.3 Test Procedure:
5.3.3.1 The fall prevention device is mounted into the test fixture utilizing the manufacturer’s written installation instructions.
5.3.3.2 The impactor (100 lb) (45.3 kg), such as in Figures 2 and 3 from ANSI Z97.1 (see Appendix X1), is prepared and
mounted to the test fixture cable so that when at rest it is no farther than 2 in. (50 mm) away from the horizontal and vertical center
of the window fall prevention device.
5.3.3.3 The impactor is pulled away from the specimen until the bottom of the impactor rises to the vertical distance of 12 in.
(300 mm) above the at rest position.
5.3.3.4 When all motion has stopped, the impactor is released and allowed to impact once into the test specimen.
5.3.3.5 Once the impact is completed and the test weight is removed, the tested specimen shall prohibit the free passage of a
4.0-in. (102-mm) diameter rigid sphere through or around it anywhere in the window opening (as required by applicable codes for
that jurisdiction).
5.3.3.6 The latching or locking device of the release mechanism shall remain engaged and operative after testing.
5.4 Release Mechanism Test:
5.4.1 Apply a force of no greater than 15 lbf (66 N) in the direction normally associated with opening (releasing) the release
mechanism of the window fall prevention device in accordance with manufacturer’s instructions.
5.4.1.1 Neither of the two distinct actions necessary to activate the release mechanism shall require a force greater than 15 lbf
(66 N).
5.4.2 The window fall prevention device shall open promptly after the release mechanism has been activated.
5.4.3 Re-secure window fall prevention device into a closed position.
5.4.4 Perform this procedure for a total of five times with zero failures within a 2-min period. The release mechanism shall
not fail to operate.
6. Safety Information
6.1 Safety information shall be distinct from the Installation Instructions. Safety information shall be headed “IMPORTANT
SAFETY INFORMATION” and shall contain a note of attention to the installer to leave the safety information behind for the
occupant.
6.2 Safety information shall include at least the information, signal word panels, and graphics contained in 6.4, 6.5, and 6.6.
