Which of the following is true about fixed ladders?
A. They must have safety devices if the ladder extends more than 18 feet above a surface.
B. Each rung must be able to support 175 pounds.
C. All safety devices must be activated within 2 feet of a fall.
D. All safety devices must be activated within 4 feet of a fall.
Answer (2)
The true statement about fixed ladders is that they must have safety devices if the ladder extends more than 18 feet above a surface, making option A the correct choice. Other options regarding rung support weight and safety device activation distances are incorrect or misstate the regulations. Safety devices are crucial for ensuring the safety of those using the ladders in high places.

The question relates to the safety requirements for fixed ladders, which is a topic generally covered in engineering and safety regulations. Fixed ladders are permanent fixtures designed to provide access between different levels, commonly used in industrial settings or on the exteriors of buildings.
To ensure safety, there are specific regulations and standards that must be adhered to, particularly under Occupational Safety and Health Administration (OSHA) guidelines in the United States:
Height and Safety Devices : Fixed ladders require safety devices if they extend more than 24 feet above a surface. This often includes the installation of ladder safety systems, cages, or wells to prevent falls.
Rung Requirements : Each rung, cleat, or step of the ladder must be able to support a load of at least 250 pounds applied in the middle of the step.
Activating Safety Devices : Safety devices should be activated within a specified distance during a fall. According to OSHA regulations, safety devices such as a ladder safety system should be designed to activate within a distance of 3.5 feet (42 inches) of a fall.
Therefore, based on these guidelines, the correct statement from your options is related to safety devices being activated within a specified distance during a fall. If these guidelines have been revised, make sure to refer to the current standards on the OSHA website or relevant local regulations for the most accurate and up-to-date information.
