DEATHS IN THE WORK PLACE
  • 101,500 Deaths in the work place (2003)
  • 116,385 Deaths in the work place 1969 (highest)
  • 86,777 Deaths in the work place 1992 (lowest)
  • In 2003 there were 16,200 deaths due to falls
  • Just a note every 5 minutes there is a fatal accident and every 1.6 seconds a disabling injury occurs.  This had a cost of  $607.7 billion.  If  we  took out  motor vehicle accidents, falls are the #1 cause of death in the workplace. (Statistics are quoted from the National Safety Council)



6
Key Areas of Concern
  • Falls from heights
  • Confined spaces
  • Lift equipment
  • Scaffolds
7
REDUCE FALLS BY
ELIMINATING THE RISK
  • Don’t go there
  • Build a work platform
  • Implement a personal fall arrest system
  • Use alternative means
8
Fall Protection
  • A series of steps taken to reasonably lessen or eliminate the risk of falling in the work place
9
What Is Fall Protection?
  • Is it Equipment?
  • Is it Planning?
  • Is it a Culture change?
  • It is all of the above
10
The Regulatory Environment
  • Employers have the GENERAL DUTY to provide a safe, healthy workplace
11
Hierarchy of Regulation
  • State or federal standards
    • Minimum acceptable
  • Manufacturer notices, warnings, instructions
  • Employer safety policy
12
Two Types of Personnel Are Described
  • Competent
  • Qualified
13
Competent Persons
  • Know application limits
  • Regulations
  • Able to “solve and resolve” problems
  • Have authority to take necessary actions
14
Qualified Persons
  • Degree or certificate of competency
    • PE
  • Vast experience
  • Skill necessary to “solve and resolve” technical problems
15
Personal Fall Arrest Systems
  • Must be in place when the risk is present
  • Must limit impact loads on the victim
  • Must ACTUALLY work in the environment in which they are used
16
Powered Lift Equipment
  • Confusing Scenario
  • Push around lift
  • Scissor lift
  • Boom lift
17
Scissors Lift
  • Working surface
  • Not required by OSHA
  • Could be required by some companies
18
Boom Lift
  • Must be “tied off”
    • 29CFR1910.67(c)(2)(v) A full body harness shall be worn and a lanyard attached to the boom or basket when working from an aerial lift.
19
What if Conventional Fall Protection Will Not Work

  • Leading edge has 4’ exposure will a 6’ lanyard and body harness work?
  • Fall protection plans are acceptable alternative


    • Very restrictive
    • Very specific
20
Fall Protection Plans
  • Require clear statement that “conventional” fall protection “is impractical or creates a greater hazard.”
  • Must clearly identify why conventional systems are not appropriate
21
Plans Must be Specific
  • Where it is to be implemented
  • Who is responsible for implementation
  • A qualified person must approve the plan and any changes
  • The plan must be maintained on site
22
Additional Actions May be Required for Compliance
  • Title 8§1671.1(a)(9) requires controlled access zones and safety monitoring when “no other alternatives measure has been implemented….”
23
Controlled Access Zones
  • Control line set not less than 6’ nor more than 25’ from unprotected or leading edge
  • Set with lowest point no less than 39” nor more than 45” above the working level
  • Must be clearly marked at not more than 6’ intervals
24
Safety Monitoring
  • Safety monitor must be competent person
  • Must always be in communication with employees being monitored
  • Monitor should have no other responsibilities diverting attention
25
Safety at Heights: A Simple Proposition
  • A - anchorage
  • B - full body harness
  • C - connectors
  • D – devices
  • R - rescue
26
Anchor Points
  • Basic - most common alternative
  • Engineered - meets 2:1 safety factor
  • Most common errors
  •      Assume anchor point is strong enough
  •      Somebody else tied off to this anchor point
27
Can You Recognize an Appropriate Anchor?
  • 5,000 lbs
  • 3,000 lbs
  • How about a rule of thumb?
28
Anchor Point Evaluation
  • Ford F-250 Extended Cab
  • 2 WD
  • 5,058 lb.
29
B: Body Harness
  • The only acceptable device for use in a fall arrest situation
  • Spreads load to minimize injuries
    • OSHA allows 1,800 pound impact load
    • ANSI Z359.1-1992 limits impact to 1800 pounds
  • Positions victim for rescue
30
Harness Categories
  • General use
  • Specialized
  • Rescue, Climbing
31
Harness Fit
  • Legs closed tightly
  • Sub pelvic strap correctly positioned
  • D-ring positioned between shoulders
32
Harness Inspection
  • Webbing okay?
    • No burns, tears, discoloration
  • Hardware okay?
    • Properly positioned
    • No cracks
33
Connectors
  • Must be double locking
  • Must be compatible
  • Must be inspected prior to each use
34
Energy Absorbing Devices
  • Must absorb the energy built up during a fall
  • Must control energy imparted on both victim and anchor point
  • All get longer under load
35
Shock Absorber Types
  • Rip stitch
  • “Woof material”
  • Tearing
  • Self retracting lifelines
36
Inspection is Critical
  • Webbing undamaged?
  • Hardware functional?
  • Shock absorber okay?
37
Falls Actually Don’t Kill…. The Stop Does the Damage
  • Contact with lower levels, dangerous equipment
  • Swings into structures
38
Fall Protection Math
  • Lanyard length + shock absorber length + victim height + elongation = REQUIRED CLEAR SPACE
  • 6’ + 6’ + 42” + 1’ = >16’
  • Do you have this much distance?
39
Fall Protection:
  • 10% equipment
  • 90% rigging
40
Rigging Is Critical
  • Anchor set as high as possible
  • Lanyard attached properly to harness
    • Shock absorber clipped to back d-ring
41
Self Retracting Lifelines
  • Must be positioned over work area
    • Minimize swing fall potential if you practice the 30 degree rule
  • Cuts anchor requirement
    • 3,000 lbs.... Vs. 5,000 lbs..
42
Inspection Intervals
  • Title 8 Sec 1670 (19) requires that PFAS “shall be inspected not less than twice annually” by a competent person
  • Inspection date must be documented
43
Rescue: The Final Challenge
  • Most falls are self rescued
  • If rescue is required it
    • Must be timely, per OSHA
    • Must be within 15 minutes, per ANSI
  • Must be part of the plan
44
A Safety Reminder
  • Even if you were born to do a job, it doesn't necessarily mean that you're going to automatically do it safely.…
    You know what you're doing, its what you've been trained to do your whole life. Nothing could possibly go wrong, right???
  • Think again!
45
Thank You!
  • It starts right now.  Remember knowledge is not power, it is what you do with what you know that gives you power
