E N D
Types of falls • Falls from same level • Slips • Trips • High frequency rate • Low injury severity rate 1a
Types of falls • Falls from an elevation • Relatively low frequency rate • High injury severity rate • Specific potential fall hazards 1b
Common fall protection systems • Guardrail systems and toeboards • Handrail and stair rail systems • Designated areas 2a
Common fall protection systems • Hole covers • Safety net systems • Ladder cages 2b
Common fall protection systems • Ramps and bridging devices • Slip-resistant floors • Effective housekeeping 2c
What happens during a fall? • Person loses his/her balance • Body unintentionally moves from an upright position to a prone, or semi-prone position 3a
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 3b
Why falls are dangerous Falls are dangerous because of three primary elements: • The free-fall distance the worker falls • The shock absorption at impact • The body weight of the worker 4a
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 • 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 5b
Shock absorption at impact • Varies according to the types of fall protection equipment used • Shock-absorbing lanyards reduce the probability of injury 6a
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 7a
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 8a
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 • 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 • 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 8d
Personal fall protection • Personal fall arrest systems • Positioning device system • Personal fall protection system for climbing activities 9a
Training • Equipment inspection • Application limits • Methods of use • Donning, doffing, adjusting equipment 10a
Training • Anchoring and tie-off techniques • Emergency rescue plans and implementation • Maintenance procedures • Storage techniques 10b
Vendor/Supplier information Comprehensive instructions for fall arrest system use and application, provided by the supplier, should consist of: 11a
Vendor/Supplier information • The force measured during the sample force test • Maximum elongation measured for lanyards during the force test 11b
Vendor/Supplier information • Deceleration distance for deceleration devices measured during the force test • Caution statements on critical-use limitations 11c
Vendor/Supplier information • Application limits • Proper hook-ups 11d
Vendor/Supplier information • Anchoring tie-off techniques • Proper climbing techniques 11e
Vendor/Supplier information • Methods of inspection, use, cleaning, storage • Lifelines 11f
Reporting fall hazards • Employees will not experience repercussions from reporting hazards • Employees should report unsafe equipment, conditions, procedures 12a
Reporting fall hazards • Equipment repair receives top priority • Under no circumstances will defective equipment be used 12b
Reporting fall hazards • When fall conditions exist: • Take short steps • Keep toes pointed out • Walk on the whole foot when crossing rough or slippery surfaces • Avoid making sharp turns • If you fall, protect your head and neck 12c
Reporting fall hazards • Disciplinary actions for failure to use equipment 12d
Housekeeping • Effective housekeeping prevents falls • Keep high work areas free from: • Tools • Materials • Debris • Liquids 13a
