Guardrail systems.
Top edge height of top rails, or equivalent guardrail system members, shall be 42 inches (1.1 m) plus or minus 3 inches (8 cm) above the walking/working level.
Your wire rope – or any other flexible material – cannot deflect below 39” when the 200 lbs of force is applied to it. Regardless of whether we're discussing a rooftop guardrail system, a temporary railing system, or a job-made railing the height of the top rail must always be 42” (plus or minus 3” in Construction).
Working at Heights — Any work at height of 1.8 meter or more from the ground level or floor. Elevated working positions where the hazard of a fall exists and where there is no physical protection such as handrails.
Consists of top rail, mid rail, and posts. Height from the upper surface of top rail to floor level is 42 inches. Mid rail height is 21 inches.
The height requirement for guardrail for a typical single-family detached home is at least 36”. This includes the space between the platform itself and the top rail. Meanwhile, commercial decks have slightly stricter requirements. The guardrail height for a commercial deck has to be at least 42”.
Guardrail systems must be capable of withstanding at least 200 pounds of force applied within 2 inches of the top edge, in any direction and at any point along the edge, and without causing the top edge of the guardrail to deflect downward to a height less than 39 inches above the walking/working level.
The IRC requires guardrails to be at least 36" in height, measured from the deck surface to the top of the rail.
What must the top edge of a guardrail be?
In general, 29 CFR 1926.502(b)(1) specifies that the top edge of a guardrail system must be between 39 and 45 inches above the walking/working surface.
Crash testing shows that the specified height of 30 to 32 inches for Midwest Guardrail System (MGS) is the optimal height to prevent errant vehicles from climbing over the guardrail.
Guardrail height—The height of the toprail for scaffolds manufactured and placed in service after January 1, 2000 must be between 38 inches (0.9 meters) and 45 inches (1.2 meters).
GUARDRAIL REQUIREMENTS
Any platform 4 feet or higher above a lower floor or the ground must be protected by a guardrail on all open sides. Guardrails must have vertical heights of 42 inches from the upper surface of the top rail to floor, platform, runway, or ramp level.
Guard Railing Minimum Height: 36 Inches
Horizontal walking surfaces that have a drop-off of more than 30 inches must be protected by a guard railing. Measure the height of the guard railing vertically from the top of the walking surface to the top of the guard railing.
Going by the general rule that safe working height is ¾ of your height, a safe working height would therefore be approximately 3.85m.
Four feet is the minimum height at which precautions should be taken. It changes depending on the industry: Four feet for general industry work. Five feet for shipyards.
The term “aloft” refers to anywhere 15 feet or higher, to the point where a harness is required. The term applies to Sailors working not only on the mast, but over the side of the ship as well. While a few different departments go aloft, the duty falls mainly to combat systems.
The specific threshold may vary, but it's common for handrails to be required for stairs with three or more steps. However, some codes may require handrails for two-step stairs as well. Stair Height: Building codes may also consider the overall height of the staircase when determining the need for a handrail.
Lean Budget Guardrails in SAFe (Scaled Agile Framework) is a way to ensure that the team is not overspending on any given project. It helps the team to be more agile and responsive by providing a framework for how much work can be done within a given timeframe.
What is the difference between handrail and guardrail OSHA?
Guardrails are meant to protect personnel and other job-site hazards from falling to lower levels. Handrails are meant to provide support and guidance along stairways and platforms. Both must be smooth to touch and able to withstand 200 lbs.
The OSHA publications on warehouse safety recommend that guardrails either be tagged at regular intervals to indicate hazards or be bright yellow, which is the industry standard color of 'warning'.
Spacing between balusters cannot exceed 4 inches. In order to be up to code, U.S. building codes mandate that balusters have no more than a 4-inch gap between them.
OSHA 1910.29(b)(1):
To meet OSHA's guardrail height requirements, the top rail needs to be 42 inches plus or minus 3 inches above the walking-working surface.
Leading edges. Each employee who is constructing a leading edge 6 feet (1.8 m) or more above lower levels shall be protected from falling by guardrail systems, safety net systems, or personal fall arrest systems.
