2 Your InstructorsANDY BULLPresidentC. H. Bull Company
3 Falls KillUnrestrained falls from 10’ kill or disable 4 out of 5 victimsUnrestrained falls from 11’ kill 4 out of 5
4 PHYSICS OF A FALL Elapsed Distance Velocity Speed MPH Force at Time of fall Ft. per second impactFt LbsFt LbsFt LbsFt LbsFt LbsFt ,000 LbsFt ,000 LbsFt ,600 Lbs*calculations based upon a 200 pound worker including tools.
5 Construction In 1995 1,048 people died on the job 32% of fatal accidents involved falls
6 Key Areas of Concern Falls from heights Confined spaces Lift equipment Scaffolds
7 Eliminating the Risk Don’t go there Build a work platform Implement a personal fall arrest systemUse alternative means
8 Fall ProtectionA series of steps taken to reasonably lessen or eliminate the risk of falling in the work place
9 What Is Fall Protection? Equipment?Planning?A culture change?It is all of the above
10 Key Fall Exposures, Concerns At heightsWhen positionedConfined spacesLift devices
11 The Regulatory Environment Employers have the GENERAL DUTY to provide a safe, healthy workplace
12 Hierarchy of Regulation State or federal standardsMinimum acceptableManufacturer notices, warnings, instructionsEmployer safety policy
13 Generally Speaking the Regs Require Fed OSHA limits free falls to 6’ or lessCal/OSHA limits free fall to 30” or moreSpecial criteria for confined space workFall protection in lift devicesScaffold builders to be “tied off”
14 Specific Regulations 29CFR1910 29CFR1926 Multiple state regulations CAL/OSHA of Regulations, Title 8Subchapter 7
15 Two Types of Personnel Are Described CompetentQualified
16 Competent Persons Know application limits Regulations Able to “solve and resolve” problemsHave authority to take necessary actions
17 Qualified Persons Degree or certificate of competency Vast experience Skill necessary to “solve and resolve” technical problems
18 Personal Fall Arrest Systems Must be in place when the risk is presentMust limit impact loads on the victimMust ACTUALLY work in the environment in which they are used
19 At Heights Maximum free fall Minimum anchor strength Maximum impact loadsAdequate clear space for useFall protection is 10% equipment; 90% rigging
20 When Positioned A fall of NO MORE THAN 2 FEET A minimum 3,000# anchor All other hardware must meet PFAS requirements
21 Confined Space Fall Protection and Retrieval Needs HolesExcavationsShip maintenance & constructionTanks
22 Types of Confined Space Permit Required - IDLH situations may be encounteredNon Permit Required - NO IDLH situations
27 Boom Lift Must be “tied off” 29CFR (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.
28 One More Look at Boom Lifts Do you see any problems here?Free fall potential?Anchor strength?Basket capacity?
29 Scaffold Fall Protection ????Conflicting guidance aboundsCAL / OSHA Title 8Subchapter 18 has the most information on scaffold
30 Federal Regulatory Basis OSHA29 CFR 1926 Sub RSteel erection only29 CFR 1926 Sub MWell documented6’ free fall
31 29CFR1926 Sub R Significant changes (a) sets 15’ “trigger height” with exceptionsSpecific training
32 Definition of “Steel Erection” “…the construction, alteration or repair of steel buildings…installation of decking…used in the process of erection.”29CFR
33 Connectors Protected from falls of more than 30’ 29CFR (b)(1)15’ to 30’ PFAS or positioning or restraint system29CFR (b)(3)
34 DeckingEstablished procedures for controlled decking zone (CDZ)
35 What if Conventional Fall Protection Will Not Work Fall protection plans are acceptable alternativeVery restrictiveVery specific
36 Fall Protection PlansRequire clear statement that “conventional” fall protection “is impractical or creates a greater hazard.”Must clearly identify why conventional systems are not appropriate
37 Plans Must be Specific Where it is to be implemented Who is responsible for implementationA qualified person must approve the plan and any changesThe plan must be maintained on site
38 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….”
39 Controlled Access Zones Control line set not less than 6’ nor more than 25’ from unprotected or leading edgeSet with lowest point no less than 39” nor more than 45” above the working levelMust be clearly marked at not more than 6’ intervals
40 Safety Monitoring Safety monitor must be competent person Must always be in communication with employees being monitoredMonitor should have no other responsibilities diverting attention
41 Safety at Heights: A Simple Proposition A - anchorageB - full body harnessC - connectorsD - devices
42 Anchor Points Basic - most common alternative Engineered - meets 2:1 safety factorMost common errorsAssume anchor point is strong enoughSomebody else tied off to this anchor point
43 Can You Recognize an Appropriate Anchor? 5,000 lbs3,000 lbsHow about a rule of thumb?
44 Anchor Point Evaluation Ford F-250 Extended Cab2 WD5,058 lb.
45 Anchorage Selection 5,000 pound requirement Set as high as possible Cuts free fallUse correct deviceCable or web slingCarabiner, handgrip
46 Weight LimitsMost fall arrest equipment sold in the United States has a stated weight limit of 310 pounds.Why?Anchor quality
47 B: Body HarnessThe only acceptable device for use in a fall arrest situationSpreads load to minimize injuriesOSHA allows 1,800 pound impact loadANSI Z limits impact to 900 poundsPositions victim for rescue
87 Summary- Engineered Systems DefinitionStandardsHazards and SolutionsWhat are the benefits of an Engineered System?
88 Benefits Cost effective Versatile Low Maintenance Very easy to use COMPLIANT
89 Inspection IntervalsTitle 8 Sec 1670 (19) requires that PFAS “shall be inspected not less than twice annually” by a competent personInspection date must be documented
90 Rescue: The Final Challenge Most falls are self rescuedIf rescue is required itMust be timely, per OSHAMust be within 15 minutes, per ANSIMust be part of the plan
91 A Safety Reminder Think again! 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!
92 Thank You!It starts right now. Remember knowledge is not power, it is what you do with what you know that gives you power
