Match the correct OSHA Fall Protection standard to its applicable industry or operation.

Construction 29 CFR 1926.501(b)(1)) General Industry 29 CFR 1910.28(b)(i)) Scaffolding 29 CFR 1926.451 (g)(1) Steel Erection 29 CFR 1926.760(a)(3)

A work area designated and clearly marked in which certain types of work (such as overhand bricklaying) may take place without the use of conventional fall-protection systems such as a guardrail, personal arrest or safety net.

Controlled Access Zone

What is the best course of action to protect the worker?

Ensure the Lanyard doesn't have any slack.

The vertical displacement of the fall arrest attachment point on the employee's body belt or body harness between onset of the fall and just before the system begins to apply force to arrest the fall.

Free Fall Distance

With respect to implementing a fall protection plan in unusual circumstances, _______________________ means that it is impossible to perform the work using a conventional fall protection system (that is, guardrail system, safety net system, or personal fall arrest system); or technologically impossible to use any one of these systems to provide fall protection.

Infeasible

A roof that has a slope less than or equal to a ratio of 4 in 12 (vertical to horizontal).

Low-slope roof

A fall protection system, such as a guardrail or safety net, that does not require any action on the worker's part and will provide protection 100% of the time.

Passive Fall Arrest System

A safety system in which a competent person is responsible for recognizing and warning workers of fall hazards.

Safety Monitoring System

A deceleration device containing a drum-wound line that can be slowly extracted from, or retracted onto, the drum under minimal tension during normal employee movement and, after onset of a fall, automatically locks the drum and arrests the fall.

Self-Retracting Lifeline/Lanyard (SRL)

Also known as orthostatic incompetence, this life threatening condition occurs when a person is suspended in a fall protection harness causing blood to pool in the legs, robbing the brain and heart.

Suspension Trauma

What is the maximum number of workers a safety monitor is allowed to monitor according to OSHA rules?

There is no stated maximum number.

Any side or edge (except at entrances to points of access) of a walking/working surface, e.g. floor, roof, ramp, or runway where there is no wall or guardrail system, at least 39 inches high.

Unprotected Edge

Which of the following is NOT a consideration of fall protection training?

must correct all fall protection hazards prior to training.

It is permissible to use a crane hook or load line as an anchor for a PFA system so long as a qualified person can determine that it can hold at least 5000 lbs.
