BABY WALKER INCIDENT
INVESTIGATIVE GUIDELINE
I.
A.

INTRODUCTION
Background Information

The Consumer Product Safety Commission (CPSC) has long
recognized the hazards associated with baby walkers. Efforts
to address injuries associated with these products have
included the publication of mandatory safety standards,
participation in the development and revision of a voluntary
standard, and dissemination of a variety of consumer
information materials. A recent review of data on children's
hazards through CPSC's Hazard Screening Project suggested
baby walker injuries to be a potential area for further study
or future project activities.
In 1992, CPSC was petitioned by the Consumer Federation
of America (CFA), the American Academy of Pediatrics (AAP),
the Washington State Chapter of the AAP, the National Safe
Kids Campaign, and Consumers Union to ban baby walkers. The
petitioners asserted that baby walkers have been a major
source of childhood injury, and that the voluntary safety
standard for walkers [developed through the American Society
for Testing and Materials (ASTM)] and numerous consumer
education efforts (by CPSC and others) have had little or no
effect on the number of injuries each year. The petitioners
also alleged that walkers caused adverse developmental
effects on children.
The Commission voted to deny the petition in April 1993,
stating that the record could not support the requested
action. However, the staff was directed to develop a project
for Commission consideration that would contain
recommendations for an appropriate course of action to
address the alleged hazards associated with baby walkers.
The project was approved at mid-year review. This special
study of walker-related injuries is a major part of the
project.

Preliminary findings by CPSC staff indicated that the
risk of walker-related injuries relative to the number of
live births in the U.S. has remained virtually stable since
1984. The literature did not support a conclusion that
walkers caused adverse developmental effects. Nevertheless,
the CPSC estimates that there were about 27,000 walkerrelated injuries to children under 15 months of age treated
in U.S. hospital emergency rooms in 1991. About 80 percent
of these injuries involved falls down steps, stairs, or
between levels. About one-third of these injuries could be
classified as potentially serious, in that they included
fractures, concussions, dislocations, amputations, burns, or
internal injuries. In addition, the CPSC staff is aware of
about one death per year involving baby walkers.
The goal of this special study is to more fully identify
the circumstances involved in baby walker incidents.
Information collected will be used to answer the following
questions:
1) Can product modifications be developed to address the
identified hazards?
2) What portion of the injuries would be addressed by
these modifications?
Data collection will continue over a 12-month period. A
sample of about 300-400 cases identified through the National
Electronic Injury Surveillance System (NEISS) will be
followed up by telephone investigations to obtain additional
information about the incident. Incidents involving falls
down steps or stairs, as well as other incidents for which
additional detail is required, will be reassigned for on-site
investigation. Analysis of the data is expected to be
completed in the spring of FY 1995.

Product Description

Baby walkers are described by ASTM as "a mobile (or
immobile) unit which enables a child to move forward or
sideward while learning to walk." A baby walker generally
consists of a fabric seat with leg openings mounted to a
rigid plastic deck, often with a feeding tray.

2

The deck is attached to a base with wheels. Walkers
generally can be folded for storage, and may have adjustable
seat heights and a bouncing mechanism. Activity
toys may be attached to the trays. Some walkers have wheellock mechanisms (see figure below).

Specific Items of Interest

Incidents involving falls down steps or stairs are of
particular interest, in that they account for the majority of
injuries. Information on the width of the doorway or
stairway entrance, measured at the narrowest point where the
walker would pass through, is critical to determining whether
product modifications, such as increasing the diameter of the
walker, will be effective in preventing these incidents. It
is also critical to determine whether the walker complied
with the 1986 ASTM voluntary standard or the 1989 revisions
to the standard. Both included safety labeling requirements
including warnings about use near stairs, steps, and
thresholds. The 1989 revision requires a permanent stairs
warning label on each product in a place which will be seen
by the consumer when placing the child in the walker,
"WARNING: Avoid serious injury. NEVER use near stairs." It
is essential to report the age of the walker, as well as the
presence, content, and location of warning labels. The
manufacturer and model of the walker should be reported
whenever available.
For the FY 93-94 special study, a systematic random
sample of cases will be selected for follow-up telephone
investigation from CPSC Headquarters. A portion of these
cases (primarily stair-fall incidents) will be assigned for
on-site investigation for further information. A copy of the
completed telephone investigation questionnaire (see
Attachment 1) will accompany all on-site reassignment
messages. Where appropriate, field investigators should make
corrections and additions to the information reported on the
telephone questionnaire. However, on-site investigations
provide invaluable additional descriptive information about
the product, victim, and circumstances involved, and
therefore should not be limited to the data elements
requested on the telephone questionnaire.

time of the incident.
• Report the number of steps or stairs travelled by the
walker, including the top step or stair.
• Try to find out the orientation of the walker as it
started down the steps or stairs. Did it go down
forward, backward, or in some other way? Did it
remain upright, or did it tumble over during the
fall. Was the walker upright or tipped over when
it landed?
• Did the child remain in the walker throughout the
incident or did the child fall out of the walker?
D.

Description of the Injured Person
• Verify the age and sex of the injured child.
• Obtain the approximate height and weight of the
child, if available.
• Describe the type of injury and the parts of the
body that were involved. Because head injuries are
of particular interest, provide as much detail as
possible for such injuries (e.g., area involved,
severity, symptoms, etc.).
• Describe the type of treatment received at the
hospital, and state whether there appear to be any
lasting or permanent effects due to the incident.
8

If the child was admitted for hospitalization,
report the length of stay. If the child received
any follow-up treatment after the hospital visit,
please describe.
E.

Product Usage/Exposure

In evaluating possible risks of injury, it is important
to examine various elements of the hazard scenario in
conjunction with information about the general use of the
product. Please report:
• The age of the child when he or she first started
using the walker.
• How often the walker was typically used, and how
long the child was in the walker for each use. Did
this pattern of use change over time? If, so
please describe these changes.
• Whether the time spent in the walker was more or less
than the time spent crawling.
• The rooms or locations in which the walker was most
often used.
• Specific times of day or occasions when the walker
was typically used (e.g., when parent was preparing
meals).
• Safety precautions generally taken before the child was
put in the walker as compared to safety precautions
taken before the child was put on the floor (when not in
the walker).
• Any functions of the walker that the caregiver
considered to be particularly important or useful
(e.g. kept the child happy/quiet, helped the child
to get exercise, etc.). If safety is reported as
an important walker function try to find out the
caregiver's rationale.
• Products sometimes used in lieu of the walker (e.g.,
playpen, high chair, etc.).
• Previous incidents the victim or siblings may have
experienced with this or other baby walkers.
Describe such incident(s) and note the nature and
extent of any injuries that may have resulted.
9

• Whether the child used the walker since the
incident, or would be likely to use it in the
future. If not, describe the reasons why (e.g.,
walker broken, caregiver considers the walker too
dangerous, etc.)
F.

Product Safety Standards

1.

Mandatory Standards

Infant walkers are subject to the banning regulation
under 16 CFR 1500.18(a)(6) of the Federal Hazardous
Substances Act unless they meet the criteria described under
16 CFR 1500.86(a)(4). Under the 16 CFR 1500.86(a)(4)
requirements, infant walkers must be designed to:
• prevent injury from any scissoring, shearing, or
pinching when the frame or other components rotate;
• cover coil springs with spaces greater than 0.125
inches;
• guard any holes, slots, cracks greater than 0.125
inches;
• prevent incidental collapse;
• provide the name and address of the manufacturer,
packer, distributor, or seller; and
• provide code mark on the article, package container, and
on the invoice or shipping records.
In addition, walkers are also subject to the mandatory
standards for small parts, 16 CFR 1501; the sharp point
technical requirements, 16 CFR 1500.48; the sharp edge
technical requirements, 16 CFR 1500.49; and the ban of excess
lead-in-paint, 16 CFR 1303.
Hazards not covered by the mandatory regulations could be
addressed under Section 15 of the Federal Hazardous
Substances Act where appropriate.
2. Voluntary Standard
The ASTM voluntary standard, ASTM F977, Standard
Consumer Safety Performance Specification for Infant Walkers,
contains performance requirements addressing stability,
structural integrity, and occupant retention; test methods;
and labeling requirements.

10

The labeling requirements address instructional
literature, product identification, and warnings and/or
graphics on the product. The warnings on the walker are to
be displayed so that they can be seen during some phase of
assembly or product use (see Attachment 2). In general, the
required warnings are:
•
•
•
•

never leave the child unattended;
never use near stairs, steps, or thresholds;
make certain both feet of the child touch the floor; and
avoid burn injuries, by keeping children away from
ranges, radiators, space heaters, and fireplaces.

In an 1989 revision of the voluntary standard, an
additional stair warning label was required to be placed on
the walker in a place that will be seen by the consumer when
placing a child in the walker. The stair warning states:
"WARNING: Avoid serious injury. NEVER use near stairs."
The instructional literature is required to include an
additional warning that the child "...should always be kept
in view while in the walker."

11

INSTRUCTIONS FOR PHOTOGRAPHING AND DIAGRAMMING THE
INCIDENT SCENE AND PRODUCT INVOLVED.
• Please photograph the walker from front, side, and
overhead views to illustrate the walker base (e.g.,
round, rectangular, etc.) and number of wheels.
• Photograph any warning labels and graphics on the
walker to illustrate their location and content.
• Diagram the room or area in which the incident
occurred to illustrate the path of the walker
during the incident sequence. If the incident
involved a fall down steps or stairs, diagram the
step or stairway opening and provide the inside
width (in inches) of the opening at the narrowest
dimension (e.g., the inside edges of the door
frame) close to the floor.
• Photograph the floor or floor covering(s) present under
the walker during the incident.
• If a threshold strip was present in the incident
location, photograph and provide a diagram of its crosssectional dimensions.
IV.

INSTRUCTIONS FOR OBTAINING DOCUMENTS RELATED TO
THE INVESTIGATION
• Obtain medical records, i.e., emergency room records
or hospitalization records.
• If a death occurred, obtain all available medical
records and other documentation from the medical
examiner or coroner, police, and other knowledgeable
parties.
