What happens during a fall?

What happens during a fall?
Person loses his/her balance

What happens during a fall?
Person loses his/her balance
Body unintentionally moves from an upright position to a prone, or semi-prone position

3b
What happens during a fall?
Free-fall velocity at impact when falling 12 feet is nearly 20 M.P.H.

What happens during a fall?
Free-fall velocity at impact when falling 12 feet is nearly 20 M.P.H.
Person hits the ground in less than one second from this distance

Why falls are dangerous

Falls are dangerous because of three primary elements:
Why falls are dangerous

Falls are dangerous because of three primary elements:
The free-fall distance the worker falls

Falls are dangerous because of three primary elements:
The free-fall distance the worker falls
The shock absorption at impact

Free-fall distance
5a
Free-fall distance
The uncontrolled length of travel before a worker hits the floor, ground, or before fall arrest equipment activates
5a
Free-fall distance
The uncontrolled length of travel before a worker hits the floor, ground, or before fall arrest equipment activates
5a
Free-fall distance
The uncontrolled length of travel before a worker hits the floor, ground, or before fall arrest equipment activates
Measured from the foot level before the fall, to the foot level after the fall
5a
Free-fall distance
5b
Free-fall distance Free-fall distance should be limited to a few feet
so as to prevent injury from:
• collisions with grade level
• collisions with obstructions near the work site
• pendulum-like swings that result in collision with objects

Shock absorption at impact

Shock absorption at impact Varies according to the
types of fall protection equipment used

Shock-absorbing lanyards reduce the probability of injury

Body weight of the worker

Body weight of the worker
Falls have more severe impact on heavy workers
7a
Body weight of the worker
Falls have more severe impact on heavy workers
“The bigger they are, the harder they fall.”
7a
Body weight of the worker
Falls have more severe impact on heavy workers
“The bigger they are, the harder they fall.”
Heavy workers may have larger waistlines, preventing fall arrest equipment from fitting properly

Fall arrest systems
8a
Fall arrest systems
Used when engineering controls are not feasible or sufficient to eliminate the risk of a fall

Fall arrest systems
Used when engineering controls are not feasible or sufficient to eliminate the risk of a fall
Fall arrest systems should match the work situation

Fall arrest systems
8b
Fall arrest systems
Fall arrest systems should:
• prevent a worker from falling more than 6 feet
• prevent a worker from contacting any lower level during arrest of a fall
8b
Fall arrest systems
8c
Fall arrest systems Fall arrest systems should:
• limit the maximum arresting force on an employee to 1800 pounds when a worker uses a body harness
• bring a worker to a complete stop
• limit the deceleration distance a worker travels to 3 1/2 feet
8c
Fall arrest systems
8d
Fall arrest systems Fall arrest systems should:
• have sufficient strength to withstand twice the potential energy impact of a worker falling a distance of 6 feet - or-
• have sufficient strength to withstand the free-fall distance permitted by the system, whichever is less
