Safety Standards for Equipment and
Facilities
• Concerns relative to materials, durability,
establishment of standards, manufacturing,
testing methods, and requirements for use
• Must be in place relative to maintenance
• Concern should be protective ability not
appearance of equipment
• A number of groups and agencies are
involved in standardizing sports equipment
and facilities

Equipment Reconditioning and
Recertification
• NOCSAE has established test standards in
order to reduce head injuries
– Set minimum safety requirements for helmets and
masks for football, baseball/softball and lacrosse
– Accepted standards for various regulatory bodies
in sports
• Type of helmet, amount of use/intensity will
determine condition of help over a period of
time
© 2010 McGraw-Hill Higher Education. All rights reserved.
• NOCSAE label does not warranty helmets
– Indicates helmet met requirements when manufactured or
reconditioned
• NOCSAE recommends reconditioning and
recertification of equipment
– Consumer should use discretion based on use
• Helmets undergoing reconditioning can meet
performance for many seasons depending on model &
usage
– Will help equipment last longer
– If not kept clean various skin conditions and infections can
be unnecessarily transferred
© 2010 McGraw-Hill Higher Education. All rights reserved.
Legal Concerns
• Increasing amount of litigation regarding
equipment
– Must foresee all uses and misuses and warn
user against potential risks inherent in
equipment misuse
• If equipment results in injury due to defect
or inadequacy for intended use
manufacturer is liable
• If equipment is modified --modifier
becomes liable

Off the Shelf vs. Custom Protective
Equipment
• Off the shelf equipment
– Pre-made and packaged
– Can be used immediately
• Neoprene sleeves, inserts, ankle braces
– May pose problem relative to sizing
• Customized equipment
– Constructed according to the individual
– Specifically sized and designed for protective
and supportive needs
© 2010 McGraw-Hill Higher Education. All rights reserved.
Head Protection
• Direct collision sports require head protection due
to impacts, forces, velocities and implements
• Football Helmets
– National Operating Committee on Standards for
Athletic Equipment (NOCSAE) develop standards for
football helmet certification
– Must be protective against concussive force
– While helmets must be certified, they may not always
be fail-safe
– Athletes and parents must be aware of inherent risks
© 2010 McGraw-Hill Higher Education. All rights reserved.
– Each helmet must have visible exterior warning
label
• Label indicates that helmet should not be used to strike
an opponent due to risk of injury
• Also indicates risk of injury accidentally and that athlete
plays at own risk while using helmet
– Athlete must be aware of risks and what label
indicates
• Athlete reads and signs statement regarding warning
label
– There are a number of helmet manufacturers, and
even more have closed due to lawsuits and
liability cases
© 2010 McGraw-Hill Higher Education. All rights reserved.
– Football helmets generally have air or fluidfilled pockets to absorb force
• Riddell Revolution has made revolutionary
changes
– Computer designed helmet that extends further past
the jaw for additional protection and stability
– The distance between the helmet and head has been
increased
– Padding inflates to fit the player’s head shape
– The face guard system has isolated attachment
points from the shell, reducing jarring from low-level
impacts to the face guard

Helmet Fitting
• When fitting head/hair should be wet to simulate
sweat
• Follow manufacturer’s directions
• Must routinely check fit
– Snug fit (credit card test)
– With change in altitude bladder helmets must be
rechecked
– Chin straps (2, 4, or 6 strap systems)
– Jaw pads are essential (prevent lateral rocking)
• Certification is of no avail if helmet is not fit and
maintained

Ice Hockey Helmets
• Undergone extensive testing in an effort to
upgrade and standardize
• Must withstand high velocity impacts (stick
or puck) and high mass low velocity
impacts
• Helmet will disperse force over large area
and decelerate forces that would act on
head (energy absorption liner)
• Helmets must be approved by Canadian
Standards Association (CSA)
© 2010 McGraw-Hill Higher Education. All rights reserved.
© 2010 McGraw-Hill Higher Education. All rights reserved.
Baseball/Softball Batting Helmets
• Must withstand high velocity impacts
• Research has indicated that helmet does
little to dissipate energy of ball
• Possible solution would be to add
additional external padding
• Helmet must still carry NOCSAE stamp
(similar to football label)
© 2010 McGraw-Hill Higher Education. All rights reserved.
Cycling Helmets
• Designed to protect the head during one
single impact
• Football, baseball and hockey helmets are
more durable and can survive repeated
blows
• Many states require use of cycling
helmets, especially in adolescents
© 2010 McGraw-Hill Higher Education. All rights reserved.
Lacrosse Helmets
• Required for male lacrosse players; females
must wear protective eye-guard
• Hard plastic with wire mess cage
• Must have center bar running from top to
bottom to absorb repeated, high velocity
blows
• Four point buckling system to keep helmet in
place and ensure better fit
© 2010 McGraw-Hill Higher Education. All rights reserved.
Face Protection
• Four categories
– Face Guard
• Has reduced the number of facial injuries
• Number of concussions has increased because
head is most often used in initial contact
• There are a variety of protective options depending
on sport and position
• Proper mounting of the mask must occur with no
additional attachments that would invalidate the
manufacturer’s warranty
• All mountings must be flush to the helmet
© 2010 McGraw-Hill Higher Education. All rights reserved.
• In high school hockey, face masks are required (with
white plastic coating) that meet Hockey Equipment
Certifications Council and American Society for Testing
Materials
• Opening can not allow passage of sticks or pucks
• Additional polycarbonate face shields are also available
• The use of throat protectors is also mandated at some
levels
– Throat Protection
• Laryngotracheal injuries, while uncommon can be fatal
• Baseball catchers, lacrosse goalies and ice hockey
goalies are most at risk
– Should be mandatory in these sports

– Mouth Guards
• Most dental injuries can be prevented with
appropriate customized intraoral mouth guards
• Protect teeth, minimize lip lacerations, absorb
shock of chin blows, and prevent concussions
• Should fit comfortably, not impede speech or
breathing
• Should extend back as far as last molar
• Constructed of flexible resilient material formed
to fit teeth and upper jaw
© 2010 McGraw-Hill Higher Education. All rights reserved.
• Do not cut down mouth guard as it voids
warranty for dental protection and could
become dislodged and disrupt breathing
• Three types
– Stock
– Commercial (formed following submersion in water)
– Custom (fabricated from dental mold)
• Mandated use in high school and collegiate
levels
• Mouth guards wear down over the course of a
season
– Coaches should routinely inspect mouth guards to determine
if replacement is necessary
© 2010 McGraw-Hill Higher Education. All rights reserved.
– Ear Guards
• Most sports do not use
• Wrestling, water polo and boxing utilize to prevent ear
irritation and ultimate deformity of ears
– Eye Protection Devices
• Highest percentage of eye injuries are sports related
• Generally blunt trauma
• Glasses
– May slip on sweat, become bent, fog, detract from peripheral
vision or be difficult to wear with headgear
– Properly fitting glasses can provide adequate protection
– Lens should be case hardened to cause crumbling and not
splintering on contact (disadvantage = increased weight)
– Polycarbonate lens is virtually unbreakable
– May have polarizing/tinting ability
– Plastic lenses while lightweight are easy to scratch
© 2010 McGraw-Hill Higher Education. All rights reserved.
– Contact Lenses
• Become part of the eye and move with it
• Corneal and sclera lenses
• Peripheral vision, astigmatisms and corneal
waviness is limited
• Will not fog and can be tinted
• Disadvantages include cost, corneal irritation,
possibility of coming dislodged
• Soft hydrophilic lenses and disposable lenses
are very popular
© 2010 McGraw-Hill Higher Education. All rights reserved.
– Eye and Glasses Guards
• Necessary in sports with fast moving projectiles
• Athletes not wearing glasses should wear closed
eye guards to protect orbital cavity
• While eye guards afford great protection, they can
limit vision
• Polycarbonate eye shield have been developed for
numerous pieces of head gear
– Neck Protection
• Serve primarily as a reminder to athlete to be
cautious rather than providing definitive restrictions

• Football Shoulder Pads
– Two types
• Cantilevered - bulkier and used by those engaged in
blocking and tackling
• Non-cantilevered - do not restrict motion (quarterback and
receivers)
– Rules of fitting
• Width of shoulders must be measured
• Inside of pad should cover tip of shoulder in line with
lateral aspect of shoulder
• Epaulets and cups must cover deltoid and allow motion
• Neck opening must allow athlete to raise arms over head
w/out pads sliding forward and back
• With split clavicle pads, channel for top of shoulder must
be in proper position

• Straps underneath arms should hold pads firmly inplace, w/out soft tissue restriction
– Combinations of padding (football and hockey)
may be used to supplement padding and
protection
• Sports Bras
– Significant effort has been made to develop
athletic support for women
– Most designed to minimize excessive vertical
and horizontal movements that occur with
running and jumping
– To be effective, should hold breasts to chest,
preventing stretching of Cooper’s ligament
© 2010 McGraw-Hill Higher Education. All rights reserved.
– Types available
• Compressive (bind breasts to chest wall - recommended
for medium size breast)
• Support (heavy duty with additional upward support for
larger breasts)

• Heel Counter - prevents medial and lateral roll
of foot
• Shoe Uppers - top of shoe made with
combination of materials, designed for
appropriate ventilation, drying and support
• Arch Support - durable but soft and supportive
to foot
• Price- due to impact on performance and injury
prevention, may be worth the extra investment
© 2010 McGraw-Hill Higher Education. All rights reserved.
• Shoe fitting
– Measure both feet, as there will be slight
differences
– Approximate conditions of use
– Fit at the end of day due to gradual increase in
volume due to weight bearing
– Should be snug but allow ample movement of foot
and toes
– Should break at widest part, coinciding with ball of
foot
– Must also consider width of shank, non-yielding
nature of sole and function of arch support
