What is the OSHA standard for railings?
OSHA states that guardrail must reach a height of 42 inches, plus or minus 3 inches, above the walking-working surface and withstand a force of 200 pounds at any point in a downward or outward direction. If the railing dips below 39 inches, due to the force, the railing is not OSHA compliant.
What is the maximum gap between handrails?
As a result, four inches would be the maximum allowable opening between the two handrails.
What is the maximum permitted gap between a guardrail Toeboard and the working surface?
0.25-inch
Have a minimum vertical height of 3.5 inches (9 cm) as measured from the top edge of the toeboard to the level of the walking-working surface. Do not have more than a 0.25-inch (0.5-cm) clearance or opening above the walking-working surface.
What are the specifications of a standard guardrail?
(a) A standard guardrail shall consist of top rail, midrail or equivalent protection, and posts, and shall have a vertical height within the range of 42 inches to 45 inches from the upper surface of the top rail to the floor, platform, runway, or ramp level.
Where are OSHA guardrails required?
Guardrails shall be provided on all open sides of unenclosed elevated work locations, such as: roof openings, open and glazed sides of landings, balconies or porches, platforms, runways, ramps, or working levels more than 30 inches above the floor, ground, or other working areas of a building as defined in Section 3207 …
Where should a handrail start and stop?
In these settings, the railing must be continuous, starting at the nosing of the upper landing and extending at a minimum to the nosing of the lowest step or “riser.” In addition, for optimal safety, the handrail should run the entire length of the nosing line wherever possible.
What is the minimum gap between handrails?
A clear minimum gap of between 50mm and 75mm should be provided between the handrail and adjacent wall. 8. All handrails should be supported with fixings that do not obstruct the passage of hands.
What is the maximum spacing allowed between posts in a typical wooden guardrail system?
Typical specifications call for a double two-by-four top rail 42 inches (one metre) above stair level, a mid-rail, and support posts no further than five feet (1.5 metres) apart. All guardrails, especially those made of wood, should be inspected regularly.
What is the difference between a handrail and a guardrail?
While handrails are there to help slow or prevent a fall on a stair or ramp, guards are to help prevent a fall over an open side of a walking surface. Guards are required along the open sides of means of egress paths where there is a vertical drop of at least 30 in. (760 mm).
What is the minimum distance between guard rails?
Distance between guardrails, intermediate rails or toeboards shall not be less than 550mm.
Why should guardrails be 42 inches high?
Height: Top rail to walking-working surface should be around 42 inches – allows flexibility for +/-3 inches. Opening Limitations: OSHA requires a 21” midrail such that a 19” or larger spherical object cannot pass through the guardrail.
How far apart should railing spindles be?
4 inches
Balusters are the vertical guards that support the handrail. They must be installed close enough that the space between them is less than 4 inches. Most city inspectors carry a 4-inch ball with them to test the spacing. Installed balusters should withstand 50 pounds of pressure exerted over a 1-sq.
Does a handrail have to be continuous?
ADA Requirements
The Americans with Disabilities Act (ADA) explains that handrails are required on both sides of stairs and must be continuous within the full length of each stair flight. The code adds that inside handrails on switchback or dogleg stairs must also be continuous.
What is the legal gap between spindles?
The building regulations state that a 100mm sphere cannot pass through any opening and this includes between spindles. So your maximum space between spindles is 99mm.
How is post spacing calculated in railings?
Spacing of Deck Posts
Deck posts should be cut about 10 inches longer than the railing. The two most common sizes used for deck posts are 4×4 and 6×6. When using 4×4 posts, place them no more than 6 feet apart, and when using 6×6 posts, no more than 8 feet apart.
Can a guard rail be a handrail?
Often the two are used interchangeably. However, a guardrail is a barricade installed at the perimeter of a raised surface such as balconies or walkways. While a handrail is any horizontal or sloping railing especially on escalators or stairways on which you can grasp by the hand.

What’s the standard height for railing?
between 34 and 38 inches
The IRC required the top of all Handrails must be between 34 and 38 inches measured from the walking surface or the nose of the stairs.
What is code for distance between balusters?
4″
In the U.S. building codes typically require that balusters be spaced *no more* than 4″ apart. Code inspectors use a 4″ diameter ball to demonstrate that the spacing is safe: the ball should not be able to pass through any opening in the guard along a stair, balcony, or deck.
Can a 2×4 be used as a handrail?
According to the IRC (2018), you can use a 2×4 to make a handrail, but you must cut finger recesses along both sides of the board and position the lumber lengthwise on its end. Using a 2×4 as a handrail laid vertically is not allowed.
How do you calculate post spacing?
How To Plan Out Fence Posts-Calculating Post Spacing
How do you calculate railing gaps?
Subtract your spindles’ total width from the railing length you will install them to get the total width of all the combined spaces. Say, 200 cm – 45 cm = 155 cm. Divide this difference by the number of spaces you need, usually the number of spindles plus one.
What’s the difference between a handrail and a guard rail?
Guard: A building component or a system of building components located near the open sides of elevated walking surfaces that minimizes the possibility of a fall from the walking surface to the lower level. Handrail: A horizontal or sloping rail intended for grasping by the hand for guidance or support.
