Competent Person - Fall Protection Presented by Turner Safety- your instructor is Steve Turner 1
Falls in Construction Falls are the leading cause of deaths in the construction industry. Most fatalities occur when employees fall from opensided floors and through floor openings. Falls from greater than 11 ft usually result in permanent injury or fatality. Falling from 4 to 6 feet can cause serious lost-time, permanent disability or worse. 2
Fall Protection This class will test your knowledge of OSHA Standards and your ability to recognize fall hazards in the field: If you have a 10 hour or 30 hour OSHA Certification card, you should have a good handle on the basics lets see what you know. 3
Fall Protection Quiz #1 Fall Protection is required when working 10 ft. or more above a lower level- True or False? answer-false, trigger height for Fall Protection is 6 ft. Federal OSHA 4
Fall Protection Quiz #2 Describe the only work situation in which the use of a body belt is permissible? Answer-when used as a positioning device or in Fall restraint applications. 5
Fall Protection Quiz #3 Besides a Personal Fall Arrest System, name two other Fall Protection Systems. Answer- hole covers, guardrails, safety nets, impalement protection, controlled access zone, restraint and positioning devices, catch platforms, safety monitor. 6
Fall Protection Quiz #4 Because of its strength, a lanyard made of steel cable is the safest? Answer-FALSE the arresting force of steel cable on your body would be much higher than a shock absorbing lanyard. They are not permissible. 7
Fall Protection Quiz #5. In a Fall, the arresting force equalsyour body weight multiplied by? Answer- double your body weight multiplied by the distance of the Fall. 8
Fall Protection Quiz #6. Your personal Fall arrest system should be inspected once a month. Answer- FALSE, Fall Arrest Systems should be inspected before each use. 9
Fall Protection Quiz #7. Name the piece of equipment that absorbs most of the Fall arresting energy? Answer- your harness 10
Fall Protection Quiz #8. Tying a knot for a connector may be done only in a few circumstances? answer- FALSE, Fall protection lifelines harnesses and other safety lines must never be tied in a knot. These reduce capacity and may cause failure. 11

No room for mistakes up here!! What is the very first thing these guys were supposed to do before putting on their harness and climbing out on that iron? What s the maximum free-fall distance allowed when using an SRL?
If you re tied off up here and you fall off! There s one small problem
Even a Mountain Climber couldn t get out- Solution? Plan to Rescue before you go up.
How about an engineered system? Could this system be adapted to this tank area?
What is a catch platform? Is it like a NET?. Not really
Question? How close are his feet to the ground if he falls? 1. Lanyard is 6ft long- Tied at shoulder level. Distance from D-Ring to his feet is 5 ft. 5 ft Don t forget, his shock absorber pulls out an additional 4ft. 13 ft Ground Level-
Answer- 3 ft

Cal OSHA 1730 (f) Slopes Greater Than 5:12--Multiple-Unit Roof Coverings. Employees shall be protected from falls from roofs that are of a height of more than 20 feet by one or a combination of the following methods: (1) A parapet at least 24 inches high. (2) Personal Fall Protection [Section 1724(f)]. (3) Catch Platforms [Section 1724(c)]. (4) Scaffold Platforms [Section 1724(d)]. (5) Eave Barriers [Section 1724(e)]. (6) Roof Jack Systems [Section 1724(a)] (Safety lines shall be required in conjunction with roof jack systems on roofs steeper than 7:12) NOTE: For purposes of Section 1730, the height measurement shall be determined by measuring the vertical distance from the lowest edge of the roof or eaves to the ground or level below. The height of parapets shall not be included in the roof height measurements.
When you need Fall Protection.. Pre Planning is the KEY- look close and see his SRL
If this ironworker climbs out of the basket, he can hook up his lanyard to the Horizontal Lifeline system that was pre-installed before the iron was lifted into place. How close to the iron does he have to be to climb out of the basket?
Always use the right gear for the job!
Fall Protection At the end of this topic, you will be able to: List at least four methods of fall protection available for protecting workers State the main criteria that prompts use of fall protection for construction workers 30
Fall Protection Options Personal Fall Arrest System (PFAS) Guardrails Safety Net 31
32
Fall Protection Planning Lanyards and PFAS in use Fall protection systems and work practices must be in place before you start work. 33

Hierarchy of Control for Engineered Controls Fall Exposures Attempt to eliminate the hazard by removing the exposure, changing the procedure, guarding or installing barriers. Administrative Controls Training and instructions; Limiting exposure time; rotating employees, increased rest breaks Personal Protection Fall-arrest harness and lanyard, hard hat, eye protection, foot protection, respirators, hearing protection, hand protection 35
Personal Fall Arrest Systems You must be trained how to properly use PFAS. PFAS = anchorage, lifeline and body harness. 36

Guardrails Top Rail Mid- Rail Toeboard Top rails between 39 and 45 inches tall Toeboards at least 3 1/2 inches high 45
Safety Nets Place as close as possible, but no more than 30 feet below where employees work 46
Cal OSHA Safety Net Standard (trigger height) is 25 feet above the ground and 30 ft max free fall into net. installed as close as practicable under the working/walking surface up to 5-feet fall: net 8-feet out 5-10-feet fall: net 10-feet out greater than 10-feet fall: net 13-feet out 47
What is a Controlled Access Zone?
When Fall Protection is Needed Walkways & ramps Open sides & edges Holes Concrete forms & rebar Excavations Roofs Wall openings Bricklaying Residential Construction 49
Walkways and Ramps Guard ramps, runways, and other walkways 50
Fall Protection - Residential Construction In residential construction, you must be protected if you can fall more than 6 feet 51
Unprotected Sides & Edges Unprotected edge Unprotected sides and edges must have guardrails or equivalent 52
Sides & Edges - Improper Guarding This 1/4" nylon rope alone is not a proper way to guard this open floor 53
Sky Lights and Other Openings Holes more than 6 feet high must be protected This opening could be made safe by using a guardrail, or strong cover 54
Floor Holes Cover completely and securely If no cover, can guard with a guardrail Improperly Covered 55
Concrete Forms and Rebar Use PFAS when working on formwork or rebar Cover or cap protruding rebar 56
Excavations Wider than 30 inches- Cal OSHA Guard excavations more than 6 feet deep when they are not readily seen because of plant growth or other visual barriers In addition to needing guarding, this excavation is not properly shored 57
Roofs If you work on roofs and can fall more than 6 feet, you must be protected 58
Wall Openings Wall opening If you work near wall openings 4 feet or more above lower levels you must be protected from falling 59
Good Work Practices Perform work at ground level if possible Example: building prefab roofs on the ground and lifting into place with a crane Tether or restrain workers so they can't reach the edge Designate and use safety monitors (This is less desirable of all the systems) Use conventional fall protection 60
Training Employers must provide fall protection training The training is to teach you: How to recognize hazards How to minimize hazards The training must cover: Fall hazards Fall protection systems Use of fall protection devices 61
Summary If you can fall more than 6 feet, you must be protected Use fall protection on: walkways & ramps, open sides & edges, holes, concrete forms & rebar, excavations, roofs, wall openings, bricklaying, residential construction Protective measures include guardrails, covers, safety nets, and Personal Fall Arrest Systems 62
