Personal fall protection systems must be inspected before the first use during each workshift. According to OSHA's guidelines in Appendix C to Subpart I of Part 1910, this inspection is crucial to identify any damage or defects that could compromise the equipment's effectiveness, ensuring it meets the requirements of 1910.140.
You must immediately remove the harness from service if it has any damage. OSHA guidelines state that any component with a cut, tear, abrasion, mold, evidence of stretching, corrosion, distorted hooks, or other defects must be taken out of use. The damaged item should be tagged or marked as unusable, or destroyed to prevent accidental reuse, as detailed in Appendix C to Subpart I of Part 1910.
Any personal fall protection system or component that has been subjected to impact loading, such as in a fall, must be removed from service immediately. As outlined in Appendix C to Subpart I of Part 1910, it cannot be used again until a competent person inspects it and determines it is undamaged and safe for use.
Employers must ensure employees are trained in the proper use of fall protection systems before they are allowed to use them. As required by 1910.132 and detailed in Appendix C to Subpart I, training should cover:
No, you should avoid tying a knot in a lanyard or lifeline as it can reduce the strength of the line by 50 percent or more. OSHA's guidance in Appendix C to Subpart I specifically warns against this practice. Instead, use a lanyard of the appropriate length or an adjustable one designed for that purpose to comply with strength requirements in 1910.140.
While it is common practice to interchange components like lanyards and harnesses, employers must ensure that all parts are compatible. OSHA guidance in Appendix C to Subpart I of Part 1910 warns that not all components are interchangeable. Any substitution or change to a system should be fully evaluated or tested by a competent person to ensure it meets OSHA standards before being used. Always consult manufacturer specifications for compatibility.
To calculate the total fall clearance, you must add several factors together to ensure a worker will not strike a lower level. According to guidance in Appendix C to Subpart I of Part 1910, your calculation should include:
The total distance must be less than the distance to the nearest obstruction or lower level. The standard at 1910.140(d) requires that systems be rigged to prevent contact with a lower level.
No, you cannot use positioning components for fall arrest unless they are specifically designed to meet the strength and performance requirements for fall arrest systems. OSHA guidelines in Appendix C to Subpart I clarify that components intended for work positioning, such as pole straps and rebar hooks, are generally not suitable for arresting a fall and should not be interchanged with fall arrest equipment that meets the criteria in 1910.140.
Horizontal lifeline systems must be designed, installed, and used under the supervision of a qualified person. This is emphasized in Appendix C to Subpart I of Part 1910 because factors like sag angle can dramatically increase the forces on the system during a fall, requiring expert analysis to ensure it meets the requirements of 1910.140.
You should avoid tying off around sharp or rough surfaces whenever possible, as they can severely damage rope or webbing and reduce the system's strength. OSHA's non-mandatory guidance in Appendix C to Subpart I recommends using an abrasion-resistant strap, padding the edge effectively, or using a tie-off apparatus like a steel cable sling. If these alternatives are not available, you must take steps to minimize the potential free fall distance.
Give your crews cited answers they can trust, from any safety document or regulation, with your company policies built in, so work keeps moving and nothing falls through the cracks.
