Describe different types of ladders in brief. Enlist the common causes of ladder accidents.

There are several types of ladders commonly used in various industries and applications, each designed for specific tasks and environments:

1. Step Ladders: Step ladders are self-supporting, portable ladders with a hinged design that allows them to stand freely. They feature steps on one side and a platform or top cap for stability and support. Step ladders are commonly used for tasks such as painting, maintenance, and household chores.

2. Extension Ladders: Extension ladders consist of two or more sections that slide or telescope to extend to various heights. They typically feature rungs on one side and guides on the other for stability when extended. Extension ladders are suitable for accessing elevated areas such as rooftops, walls, or ceilings.

3. Platform Ladders: Platform ladders are similar to step ladders but feature a larger, flat platform at the top for added stability and comfort. They provide a secure working platform for tasks requiring extended reach or prolonged periods of work at height.

4. Rolling Ladders: Rolling ladders are equipped with casters or wheels at the base, allowing them to be easily moved and repositioned. They often feature handrails or guardrails for safety and are commonly used in warehouses, libraries, and retail environments for accessing shelves and storage areas.

5. Telescoping Ladders: Telescoping ladders are compact and adjustable, with nested sections that slide into one another for storage and transportation. They can be extended to various heights and locked into position using a mechanism such as a latch or locking pins. Telescoping ladders are versatile and suitable for a wide range of applications.

Common causes of ladder accidents include:

1. Incorrect ladder selection: Choosing the wrong type or size of ladder for the task at hand, or using a damaged or defective ladder, increases the risk of accidents.

2. Improper ladder setup: Failure to properly set up and secure the ladder, such as not extending it to the correct height, not locking it in place, or placing it on unstable or uneven surfaces, can lead to falls and instability.

3. Overreaching: Stretching too far to the side or leaning too far forward while on the ladder can cause loss of balance and falls.

4. Carrying heavy loads: Carrying heavy tools or materials while climbing or descending the ladder can throw off balance and increase the risk of falls.

5. Ignoring weight capacity: Exceeding the maximum weight capacity of the ladder or allowing multiple workers to use the ladder simultaneously can compromise its stability and lead to collapse or failure.

6. Lack of proper training: Inadequate training on ladder safety, including climbing techniques, proper use, and inspection procedures, increases the likelihood of accidents and injuries.

By addressing these common causes and promoting proper ladder safety practices, the risk of ladder accidents can be significantly reduced, ensuring the safety of workers and minimizing the potential for injuries.
