Strength of an eye-bolt is rated along th ithe axis

Strength is greatly reduced if the force is applied at an angle to this axis (in the direction of the shear))

INSPECTION REQUIREMENTS INSPECTION REQUIREMENTS

OSHA 1926 Subpart M– Before using personal fall protection systems, and after any e o e us g pe so a a p o ec o sys e s, a d a e a y

component or system is changed, employees shall be trained in the … proper methods of equipment inspection

d tand storage.

"Inspections " Personal fall arrest systems shall be– Inspections. Personal fall arrest systems shall be inspected prior to each use for mildew, wear, damage and other deterioration, and defective components shall be removed from service if their strength or function may be adversely affected.

STANDARDS STANDARDS

ANSI Standards– ANSI Z359 1-2007– ANSI Z359.1-2007

• Section 6.1.1. “Equipment shall be inspected by the user before each use and, additionally, by a competent person , y, y p pother than the user at intervals of no more than one year.”

– ANSI A10.32-2004• Section 6.3.2. “Formal inspections shall be made by either

a Competent or Qualified Person on at least a semi-annual basis.”

BACKGROUNDBACKGROUND

Miller study – May 1, 2006– Is Your Fall Protection Equipment a Silent Hazard?q p

• “All fall protection equipment deteriorates with use and exposure over time, regardless of brand and/or manufacturer.

• Equipment is not inspected often enough for wear and damage.

• Proper training is not provided--often, the wrong equipment is selected for a particular situation, and equipment is not worn p q pproperly.”


Miller study – May 1, 2006– Over several months shock-absorbing lanyards have beenOver…several months, shock absorbing lanyards … have been

voluntarily removed from job sites for safety qualification

RESCUE OSHA REQUIREMENTS RESCUE – OSHA REQUIREMENTS

“The employer shall provide for prompt rescue of employees in the event of a fall or shall assure that employees in the event of a fall or shall assure that employees are able to rescue themselves.”

Letters of Interpretations– “While an employee may be safely suspended in a body harness for a p y y y p y

longer period than from a body belt, the word “prompt” requires that rescue be performed quickly -- in time to prevent serious injury to the worker ” August 14 2000worker. August 14, 2000
