Overview

ASTM F2006-21, titled Standard Safety Specification for Window Fall Prevention Devices for Non-Emergency Escape (Egress) and Rescue (Ingress) Windows, establishes rigorous safety requirements for devices designed to prevent accidental window falls by children aged five years and younger. Published by ASTM International, this standard specifically targets fall prevention solutions for windows installed more than 75 ft (23 m) above ground level in multi-family dwellings. The goal is to address the significant risk of injury and death due to child window falls while ensuring the devices do not impede essential window functionality or emergency egress in other designated openings.

Key Topics

• Scope and Application: The standard applies only to devices used on non-emergency escape and non-rescue windows in multi-family buildings above 75 ft. It does not cover windows suitable for egress, ingress, or emergency use, nor does it apply to single-family or two-family dwellings.
• Device Types:
  • Window fall prevention screens
  • Fall prevention window guards
• Performance Criteria: Devices must prevent the free passage of a 4-in. (102 mm) rigid sphere at any point in the protected opening, even after durability and impact tests simulating child loads and accidental impacts.
• Installation and Use Requirements:
  • Devices must include clear installation instructions, labeling, and conspicuous safety warnings.
  • Proper application and secure attachment to the correct window types must be specified to maximize effectiveness.
• Limitations:
  • This safety specification does not address security or burglary protection.
  • Devices for emergency escape or rescue windows must comply with a different standard (ASTM F2090).
  • The specification does not replace local building codes or other safety regulations, which users must also consult.

Applications

Manufacturers, building owners, and property managers of multi-family buildings use window fall prevention devices and window guards conforming to ASTM F2006-21 to:

• Reduce the risk of accidental falls for young children in high-rise residential buildings.
• Ensure compliance with relevant codes and best practices for tenant safety at elevated building heights.
• Protect against liability and fulfill safety obligations without obstructing ventilation, light, or violating emergency egress codes for windows below 75 ft.

Typical applications include:

• Retrofitting older multi-story apartment buildings to enhance child safety.
• Equipping new construction projects with compliant window guards and screens at elevations exceeding 75 ft.
• Providing detailed product labeling and installation instructions so that end-users correctly install window guards/safety screens.

Related Standards

For comprehensive compliance and best practices, the following standards are relevant:

• ASTM F2090: Specifications for releasable window fall prevention devices and window opening control devices (WOCDs) for emergency escape and rescue openings.
• ANSI Z97.1: Safety glazing materials used in buildings - impact test requirements.
• ANSI/SMA 1201: Specifications for insect screens for windows and doors, informing durability requirements for exterior fall prevention screens.
• 16 CFR 1201: Safety standard for architectural glazing materials.
• International Building Code (IBC): Referencing opening limitation requirements applicable to guardrails and window openings.
• NFPA 101: Life Safety Code for emergency egress and rescue openings.

ASTM F2006-21 is a critical reference for professionals specifying, installing, or inspecting window fall prevention devices, contributing to safer living environments in high-rise residential settings. By adhering to this standard and related documents, stakeholders ensure both regulatory compliance and the protection of young children from preventable window fall hazards.

INTRODUCTION
This consumer safety specification addresses window fall prevention devices that protect against
potential falls by children age five and under through open windows not designated for emergency
escapeorrescueininstallationsmorethan75ft(23m)abovegroundlevelinmultiplefamilydwelling
buildings since windows at these heights are beyond the reach of rescue ladders currently in use.
Window fall prevention devices currently available include Window Opening Control Devices
(WOCDs), 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. This safety specification is not intended for devices applied to
windows installed in one and two family dwellings.
A special study by the U.S. Consumer Product Safety Commission indicates that young children
are at high risk of death and serious injury from window falls. Children age five and younger account
for a higher percentage of window fall fatalities and injuries.
Security from forced entry is not within the scope of this safety specification and is not the intended
function of any of the devices referred to herein. 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 safety 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. 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.
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.
Vent limiters are devices that restrict a sash from opening to a full open position. In instances where
the vent limiters restrict the sash to prevent the passage of a 4-in. (102-mm) diameter sphere, it may
be accepted as a means of complying with window fall prevention requirements in building codes.As
model building codes typically allow a less than 4-in. opening as an acceptable condition on
non-emergencyescapeandrescueopeningsandwithoutotherperformancerequirements,ventlimiters
are therefore outside of the scope of this safety specification.
Window Opening Control Devices (WOCDs) are not covered by this safety specification to avoid
confusion with devices under the scope of Specification F2006 for non-emergency escape and rescue
openings versus devices under the scope of Specification F2090 where the devices have release
mechanisms for emergency escape and rescue openings. WOCDs are a term to be used solely for
devices that comply with Specification F2090 in which the devices are releasable for sash operation
to allow escape and rescue from an emergency.
