UNDERSTAND THE
BIOMECHANICS OF
NORMAL WALKING

Litigating and handling the stairway fall case
WALKING BIOMECHANICS INVOLVE
HEEL TO TOE STRIKE
Causes of Trips
? Damaged steps
? Non-uniform, improper or irregular steps
? Taller of shorter
? Shallower tread depth
? Otherwise irregular
Tread
Riser
PURPOSE OF NORMAL
TREADS and RISES ARE TO
SUPPORT TO FOOT WHEN
BODY WEIGHT IS
CENTERED OVER BALL OF
FOOT DURING DESCENT
HORTER TREADS
PROVIDES LESS SUPPORT
O FOOT WHEN BODY
WEIGHT IS CENTERED
OVER BALL OF FOOT
DURING DESCENT,
CAUSING FOOT TO SLIP
OVER NOSING OF STEP
Understand the Key Components for
Stairway Safety
? Treads
? Rails
? Handrails
? Stair rails
? Guardrails
? Landings and Platforms
KNOW WHAT THE RISER AND
TREAD SAFETY
REQUIREMENTS ARE UNDER
UNIFORM BUILDING CODE
Stairway Construction
?RISER-The part of the stairs that will
help you accomplish the height
?THREADS-The length of plate
?STRINGER-The part of the stairs
that will hold all the weight

HAVE YOUR EXPERT THOROUGHLY INSPECT
FOR STAIRWAY VARIATIONS THAT EXCEED 3/8 OF AN INCH
SAFE RISER/TREAD PROPORTION
STAIRWAY VARIATIONS EXCEED 3/8 OF AN INCH = GOOD LIABILITY
EXAMPLE
LOOK FOR TRIP HAZARDS
FROM UNEVEN NOSINGS
Is It Smooth?
Is It Even?
Does It Have Tendency to “Catch” the Soles of a Shoe?
Are the Nosings Uniform From One Stair to Another?

Most Variations On Stairways Occur On First Two Treads
IDENTIFY WHETHER THERE
ARE VISIBILITY AND
CONTRAST ISSUES
IMPORTANCE OF CONTRAST = ASSIST IN DIFFERENTIATING
STEPS DURING DESCENT
WAYS TO MEASURE CONTRAST
LACK OF CONTRAST REDUCES HUMAN PERCEPTUAL CAPACITY
EXAMPLE
EXAMPLE OF STAIRS WITH & WITHOUT CONTRAST
NOSING CONTRAST GREATLY DIMINISHES FALLS

STAIRS OF NEARBY APARTMENTSTAIRS OF DEFENDANT’S APARTMENT
COMPARE THE DEFENDANT’S CONDUCT WITH THAT OF
OTHER BUSINESSES NEARBY IN THE LOCAL COMMUNITY
EMPHASIZE THE
MINIMAL COST TO
PREVENT THESE
HAZARDS TO THE JURY
KNOW THE APPLICABLE
HANDRAILS REQUIREMENTS
Stairways with four or
more risers, or higher
than 30 inches, must
be equipped with at
least one handrail.
PURPOSE OF HANDRAILS
1.Provide a surface to slide
hand, allowing person to
monitor progress and
stability
2.Provide grab necessary for
support in event of misstep
The IRC and residential portion of the 2009 IBC define Type II handrail as
follows:
? Handrails with a perimeter greater than 6? inches (160 mm) shall
provide a graspable finger recess area on both sides of the profile.
? The minimum width of the handrail above the recess shall be 1? inches
(32 mm) to a maximum of 2? inches (70 mm). Edges shall have a
minimum radius of 0.01 inch (0.25 mm).
MINIMUM DESIGN AND INSTALLATION REQUIREMENT
IF IT’S TOO SHORT, THEN THE RAILS ARE NOT REACHABLE
HANDRAILS SHOULD BE GRASPABLE

GRASPABILITY REQUIREMENT OF HANDRAILS
EXAMPLE OF BAD HANDRAIL
NOT GRASPABLE
GOOD BAD
Where doors or gates
open directly on a
stairway, a platform that
extends 20 inches beyond
the swing of the door must
be provided.
Platforms and Swing Doors
Stairways landings must be at least 30
inches deep and 22 inches wide at
every 12 feet or less of vertical rise
Unprotected sides of landings must
have standard 42 inch guardrail
systems
