FallingFalling

FallingFalling
• Person loses balancePerson loses balance
• Body unintentionally moves from an Body unintentionally moves from an upright position to a prone or semi-prone upright position to a prone or semi-prone positionposition
10
FallingFalling
• Free-fall velocity at impact when falling 12 Free-fall velocity at impact when falling 12 feet is nearly 20 M.P.H.feet is nearly 20 M.P.H.
• Person hits the ground in less than one Person hits the ground in less than one second from this distancesecond from this distance
11
Three primary elements:Three primary elements:
• Free-fall distance the worker fallsFree-fall distance the worker falls
• Shock absorption at impactShock absorption at impact
• Body weight of the workerBody weight of the worker
Falls are dangerousFalls are dangerous
12
Free-fall distanceFree-fall distance
• Uncontrolled length of travel before a Uncontrolled length of travel before a worker hits the floor, ground, or before fall worker hits the floor, ground, or before fall arrest equipment activatesarrest equipment activates
• OSHA measures as the OSHA measures as the foot level before the fall foot level before the fall to the foot level after to the foot level after the fallthe fall
13
Free-fall distanceFree-fall distance
Free-fall distance should be limited to a few Free-fall distance should be limited to a few feet so as to prevent injury from:feet so as to prevent injury from:• collisions with grade levelcollisions with grade level• collisions with obstructionscollisions with obstructions• High arresting forces from fall arrest High arresting forces from fall arrest

14
Shock absorption at impactShock absorption at impact
• Varies according to the types of fall Varies according to the types of fall protection equipment usedprotection equipment used
• Shock-absorbing lanyards Shock-absorbing lanyards attached to body harness attached to body harness reduce the probability reduce the probability of injuryof injury
15
Body weight of the workerBody weight of the worker• Falls have more severe impact on heavy Falls have more severe impact on heavy
workersworkers
• Fall arrest equipment may not properly fit Fall arrest equipment may not properly fit heavy workers with larger waistlinesheavy workers with larger waistlines
16
Fall arrest systemsFall arrest systems
• Used when engineering controls are not Used when engineering controls are not feasible or sufficient to eliminate the feasible or sufficient to eliminate the risk of a fallrisk of a fall
• Disabling injuries can be prevented with Disabling injuries can be prevented with proper use of equipmentproper use of equipment
17
Fall arrest systemsFall arrest systems
Fall arrest systems prevent:Fall arrest systems prevent:
• a worker from falling more than 6 feeta worker from falling more than 6 feet
• a worker from contacting any lower level a worker from contacting any lower level during arrest of a fallduring arrest of a fall
18
Fall arrest systemsFall arrest systems
Fall arrest systems limit maximum arresting Fall arrest systems limit maximum arresting force on an employee to:force on an employee to:
• 900 pounds when a worker uses a body 900 pounds when a worker uses a body beltbelt
• 1,800 pounds when worker uses a body 1,800 pounds when worker uses a body harnessharness
19
Fall arrest systemsFall arrest systems
Fall arrest systems:Fall arrest systems:• Bring worker to stop and limit deceleration travel Bring worker to stop and limit deceleration travel
distance to 3½ feetdistance to 3½ feet
• Have strength to withstand twice the impact Have strength to withstand twice the impact energy of a worker falling a distance of 6 feet energy of a worker falling a distance of 6 feet
oror
• Have strength to withstand the free-fall distance Have strength to withstand the free-fall distance permitted by system, whichever is lesspermitted by system, whichever is less
