 Review common faults with personal fall arrest

systems

 Learn key terminology and methods of

implementing personal fall arrest systems

 Review of lesser known fall protection products

available to assist the roofing industry

 Implementing effective training as part of a Fall

Protection Program

Takea eaways ys

 Participants will have understanding of many

common faults in PFAS systems

 Knowledge on key PFAS terminology and

concepts such as “fall restraint”, “calculating fall distance”, “cross-arm straps”, & mobile fall protection.

 Handouts on equipment inspections & hands-on

practical examination tool.

 Falls are the leading cause of

fatalities in construction. Approximately 1 person dies from a fall in the construction industry every workday

 Vast majority of falls under 6’ are not

fatal

 Federal law mandates fall protection

when 6’ and greater above lower level

 Most roofs are greater than 6’ high

typically have 3.5 feet of additionally woven material.

 Stitched in precise manner to

significantly reduce fall forces.

○ Construction requires forces be

reduced to 1,800lbs or less. Most equipment designed to reduce forces below 900lbs.

INCORRECT Shock absorber end of the lanyard is placed on the lifeline away from the

• body. Falling over the roof edge may

put force on the lanyard and impede the shock absorbers deployment. CORRECT The shock absorber should be as close to the body as possible. Minimize the chance of it getting disturbed during fall, maximize potential for proper deployment.

CORRECT Image depicts proper tie off. This is for demonstration purposes only. Cross arm strap must be anchored to something substantial enough to support 5,000lbs in the event of a fall (fall arrest forces), or 1,000lbs to prevent from reaching the fall hazard (fall restraint forces)

Swi wing ng Fall ll Hazar zard

Minimize swing falls:

 Work directly below

the anchor.

 Do not extend your

work zone more than 30o from the anchor.

 Manage the slack in

the rope.

 On most homes,

multiple anchor points will be required to manage swing-fall hazards.

 It is also important to

locate anchor points at a height that prevents striking a lower level should a fall occur.

 Whenever possible

connect to an anchor point located above your shoulders.

 Tie-offs below your

shoulders or at your feet increase your fall distance.

 When tie off below

shoulders is necessary, you must tie off behind you and keep lifelines tight at the roof edge to prevent more than a 6’ free fall.

MA MAKING ING PF PFAS AS W WORK RK

Always think, “What will happen if I fall?”

PRE - PLANNING

Roo

f Rep epairs

 Use of chicken

ladders & “slator” roof anchor for fall protection.

 Invest in the “competent person”

○ Capable of identifying existing and predictable hazards ○ Authorization to take prompt corrective measures

 Utilize your vendors  Training (not just an OSHA 10-hour card)

○ Initial ○ On-the-job ○ Refresher – tool box talks ○ Recurrent – annual

 Evaluation & Enforcement

○ Front Line, Middle and Upper Management ○ Recommend documenting / photographs for training ○ Helps in evaluating the effectiveness of training

"Certification of training.“

1926.503(b)(1)

The employer shall verify compliance with paragraph (a) of this section by preparing a written certification record…

1926.503(b)(2)

The latest training certification shall be maintained.

1926.503(c)

"Retraining." When the employer has reason to believe that any affected employee who has already been trained does not have the understanding and skill required by paragraph (a) of this section, the employer shall retrain each such employee. Circumstances where retraining is required include, but are not limited to, situations where:

1926.503(c)(1)

Changes in the workplace render previous training obsolete; or

1926.503(c)(2)

Changes in the types of fall protection systems or equipment to be used render previous training obsolete; or

1926.503(c)(3)

Inadequacies in an affected employee's knowledge or use of fall protection systems or equipment indicate that the employee has not retained the requisite understanding or skill.

Investing esting in in th the e Compet petent ent Per erson son

 PFAS requires a great

deal of knowledge.

 Provide thorough

training for key personnel.

 3rd parties can assist.

Vendors have great training schools

 Not just a one and

• done. Refresher

training needed, continuous education.
