What is the minimal length ladder that a worker needs to access a landing nine feet above the adjacent floor?
To determine the minimal length of a ladder needed to reach a landing nine feet above the adjacent floor, we can use the Pythagorean theorem. Assuming the ladder is positioned at a safe angle (typically around 75 degrees), the minimal length can be calculated. For a height of 9 feet, a ladder length of approximately 10.2 feet would be required when factoring in the angle for safe use. Always ensure the ladder is placed securely and follows safety guidelines.

How long must a ladder be to reach the top of a 20 ft wall if the ladder and the wall form a 32 degree angle?
A ladder leaning against a 20ft wall, with an angle of 32 degrees with respect to the wall, must be 24ft long. cos(theta) = adjacent over hypotenuse cos(32) = 20 / hypotenuse hypotenuse = 20 / cos(32) hypotenuse = 23.58
If you had a slide 3 meters long at an angle of 40 degrees how high will the ladder need to be?
Is this a vertical ladder? Another contributor's answer:Providing that the slide is on level ground and that the ladder is vertical then you have the outline of a right angle triangle with an hypotenuse (the slide) of 3 metres and an adjacent angle of 40 degrees. To find the height of the opposite (the ladder) side of the triangle use the trigonometrical sine ratio: sine = opposite/hypotenuse When the ratio is rearranged: opposite = hypotenuse*sine opposite = 3*sine 40 degrees = 1.928362829 metres So the height of the ladder needs to be nearly 2 metres high.
If a sign is 35 ft tall and i place a ladder 10 ft from the bottom of the sign how long of a ladder will i nedd to reach 15 ft up the sign?
In effect you have the outline of aright-angled triangle with an adjacent side of 10 ft and an opposite side of 15 ft and you need to find the length of the hypotenuse (which will be the ladder). Use Pythagoras' theorem to find the length of the hypotenuse: adjacent2+opposite2 = hypotenuse2 102+152= 325 square feet The square root of 325 = 18.02775638 feet So the ladder needs to be at least 18 feet in length.

How far above the work surface must a straight ladder extend?
A straight ladder should extend at least 3 feet above the work surface or landing for safe access to and from the ladder. This helps provide stability and a secure handhold when climbing up or down.
The top of a ladder must extend how many feet above the surface a worker is climbing onto?
From the US OSHA Construction standards:1926.1053(b)(1)When portable ladders are used for access to an upper landing surface, the ladder side rails shall extend at least 3 feet (.9 m) above the upper landing surface to which the ladder is used to gain access; or, when such an extension is not possible because of the ladder's length, then the ladder shall be secured at its top to a rigid support that will not deflect, and a grasping device, such as a grabrail, shall be provided to assist employees in mounting and dismounting the ladder. In no case shall the extension be such that ladder deflection under a load would, by itself, cause the ladder to slip off its support.
What is the minimum height of a ladder required for me to reach the top of the roof?
To determine the minimum height of a ladder needed to reach the top of the roof, measure the vertical distance from the ground to the top of the roof. This measurement will be the minimum height required for the ladder.
What is the minimum size for an attic access?
Approx. 21". If there is space for it, consider the size of a drop down ladder unit, which is more useful than an opening that requires a ladder.
A ladder leans against a wall making an angle of 73 degress with the ground The ladder's base is 1.17m away from the wall Determine the length of the ladder?
Providing that the ground is level and that the wall is straight, you have the outline of a right angled triangle with an adjacent angle of 73 degrees and an adjacent length of 1.17 metres. In order to find the length of the hypotenuse (which is the ladder itself) we use the cosine ratio: cosine = adjacent/hypotenuse Which when rearranged is: hypotenuse = adjacent/cosine hypotenuse = 1.17/cosine73 degrees = 4.001755235 So the length of the ladder is 4 metres correct to one significant figure.
What is an accommodation ladder?
An accommodation ladder is a flight of stairs or a ladder for lowering over the side of a ship for access to and from a small boat.
Which one of the following means of level access requires a load capacity of 5 times expected load with a minimum of 1000 pounds?
Extension ladder
When using an articulated ladder how should you access a roof?

What is the minimum length of a ladder required to access a roof surface 12 feet off the ground?
You should normally have three rungs(steps) past the surface you are climbing to from the ladder. They are a foot apart on most ladders so 15 feet would be close. Add a foot since you have to angle the ladder appropriately(scope) so 16 feet or longer is safe. A 20 foot extension ladder would be a good choice.
How can I safely access the roof using a ladder extension?
To safely access the roof using a ladder extension, make sure the ladder is long enough to reach the roof and is securely placed on a stable surface. Extend the ladder at least 3 feet above the roof edge for stability. Use proper ladder safety techniques, such as maintaining three points of contact and facing the ladder while climbing. Have someone hold the ladder at the base for added stability.
Do you need fall protection when climbing a caged ladder?
If the cage extendes for more than a specified distance without a landing, then you will need to use fall protection when climbing a caged ladder.
