PPE and Fit
Under the OSHA PPE Fit Standard, this is the maximum number of flat fingers that should fit between a harness leg strap and a worker's thigh.
What is two?
This is the exact length of the standard shock-absorbing lanyards used by ACS?
What is 6 feet?
OSHA requires floor hole protection, such as a cover or guardrail, for any floor opening measuring more than this many inches.
What is 2 inches?
To eliminate tripping hazards on a busy walking path, extension cords and air lines should be routed in this direction whenever possible.
What is overhead?
This is the mandatory lean ratio for portable extension ladders, meaning for every 4 feet of vertical height, the base must be moved this far back from the wall.
What is 1 foot?
This specific tag or stitched section on a full-body harness rips open during a fall and tells you the harness must be immediately thrown away.
What is an impact indicator?
Assuming an average worker height and standard anchor points, this is the total minimum clear fall distance required below a worker using a 6-foot lanyard.
17.5 feet?
Temporary floor hole covers must be structurally capable of supporting at least this many times the maximum intended load of workers, tools, and vehicles.
What is twice (or 2x) the load?
This is the immediate dual-action protocol a worker must take the moment a liquid chemical or oil spill is spotted on a walking surface.
What is barricade it and clean it up immediately?
When accessing an elevated roof line via an extension ladder, the side rails must extend at least this many feet past the landing surface.
What is 3 feet?
Because of recent OSHA fit enforcement, relying on a box of these generic-sized harnesses is no longer legally compliant if they don't fit your smaller or larger worker
Universal (or One-Size-Fits-All) harnesses
In the fall clearance formula, 3.5 feet is specifically allocated for this distance—the maximum length a standard shock absorber can rip open.
What is deceleration distance?
To prevent accidental removal, all temporary floor covers must be securely fastened and clearly marked with one of these two specific words.
What are "HOLE" or "COVER"?
Slips and trips are highly likely to occur when a worker carries a large load that completely blocks this safety asset.
What is their line of sight?
To ensure stability and prevent collapse under heavy loads, scaffold legs must always rest on base plates and these wooden foundations.
What are mud sills?
When wearing a full-body harness correctly, the back D-ring must be positioned exactly between these body parts.
What are the shoulder blades?
If you anchor your 6-foot lanyard here instead of overhead, your required fall clearance distance drastically increases, putting you at risk of hitting the ground on lower platforms.
What is at foot level
Standard physical barricades (guardrails) must feature a top rail set at this height, plus or minus 3 inches, above the walking surface.
What is 200 pounds?
To prevent workers from tripping and falling over debris, wood cut-offs, drywall scraps, and packaging must be cleared out at this frequency.
What is continuously throughout the shift?
While general fall protection thresholds are lower, active fall protection or guardrails are strictly triggered on scaffolding when a worker reaches this height.
What is 10 feet?
This life-threatening medical condition can cause a worker to lose consciousness in under 15 minutes while hanging suspended in a harness.
What is suspension trauma
This 1-foot variable in the clearance equation accounts for the upward sliding and stretching of the harness straps during a fall arrest.
What is harness stretch?
The top rail of a physical barricade or guardrail system must be strong enough to withstand this many pounds of downward or outward force.
What is 200 pounds?
This specific federal OSHA standard section dictates that all walking-working surfaces, passageways, and storerooms must be kept in a clean, orderly, and sanitary condition.
What is OSHA 29 CFR 1910.22 (Walking-Working Surfaces) General Industry and 29 CFR 1926.25 Housekeeping
Recent OSHA regulatory revisions proposed removing the strict 2036 hard deadline to completely replace these legacy safety structures on fixed ladders over 24 feet.
What are ladder cages (or wells)?
