In industries requiring work at heights, such as construction and maintenance, Aerial Work Platforms (AWP) and Elevated Work Platforms (EWP) ensure worker safety and efficiency by providing safe access to elevated areas.
While both provide elevated access, they differ in design and application, influencing which equipment is ideal for specific tasks. Understanding safe operation in adverse weather and correct EWP setup is essential to minimizing risks.
This article will explore the differences between AWPs and EWPs, safety tips for operating in rain, and guidelines for proper EWP positioning to ensure secure and efficient operation.
What Is the Difference Between AWP and EWP?
Both AWP and EWP are terms used to describe equipment designed for lifting workers to elevated positions to perform various tasks, such as maintenance, repairs, and construction work. Despite their similarities, these terms are used in different contexts and carry different meanings.
AWP Aerial Work Platform
AWP stands for Aerial Work Platform, which is a broad category of mobile platforms used to lift personnel and equipment to heights.
The defining characteristic of an AWP is that it provides access to high, hard-to-reach places, and the platform is typically elevated by hydraulic, pneumatic, or mechanical means. Some common types of AWPs include:
- Boom Lifts (also called Cherry Pickers): These are vehicles with an extendable arm and a platform at the end. They are particularly useful for accessing elevated areas from the ground.
- Vertical Lifts: These lifts go straight up and are typically used for tasks that require access to a height without the need for a horizontal reach.
AWPs are designed to provide temporary access to areas that are otherwise unreachable, and they are most commonly used in tasks such as window cleaning, building maintenance, and outdoor construction projects.
EWP Elevated Work Platform
An EWP (Elevated Work Platform) is a type of AWP that is specifically designed for lifting workers and tools to heights for working purposes.
The term “EWP” generally refers to a wider range of lifting platforms and includes devices like scissor lifts and boom lifts. However, in a broader sense, all aerial work platforms are categorized as EWPs if they are intended for lifting personnel and equipment to elevated positions.
- Scissor Lifts: These lifts have a platform that moves up and down via a scissor-like mechanism. They are typically used for working on large flat surfaces, such as in warehouses or on building facades.
- Boom Lifts: These are also classified as EWPs, and their defining feature is the extendable arm with a platform at the end, allowing for both vertical and horizontal movement.
In essence, AWP is a more generic term, while EWP refers specifically to platforms that are designed for working purposes and could include scissor lifts, boom lifts, and other similar equipment.
Can You Operate an EWP in the Rain?
Operating an EWP in the rain or adverse weather conditions can be risky and should only be done with extreme caution.
Whether it’s a boom lift, scissor lift, or any other type of EWP, rain can significantly affect the stability, electrical safety, and overall performance of the equipment. Let’s examine the risks involved:
Risks of Operating an EWP in the Rain
- Slippery Surfaces: When operating in the rain, the ground around the EWP can become slippery, increasing the risk of tipping or the machine sliding. This is particularly dangerous if the EWP is not positioned properly or if the operator does not use the appropriate safety measures.
- Electrical Hazards: Many EWPs are powered by electricity, and exposure to rain or wet conditions can lead to electrical shorts or malfunctions. Electrical systems, controls, and connections are sensitive to moisture, which can result in equipment failure, posing significant safety hazards to operators.
- Reduced Visibility: Rain can impair visibility, making it harder for the operator to see the surroundings, which can increase the likelihood of accidents, such as colliding with nearby objects or structures.
- Decreased Stability: Wet conditions, such as puddles or pooling water, can impact the overall stability of the platform, especially for machines with a higher center of gravity, like boom lifts. This may lead to tipping or instability when reaching high places or moving the platform.
Guidelines for Operating an EWP in the Rain
While it is generally discouraged to operate an EWP in the rain, there are situations where it might be necessary. If you must operate an EWP in wet conditions, follow these key guidelines:
- Check the Manufacturer’s Instructions: Always refer to the operator’s manual to see if the EWP is rated for use in wet conditions. Some models are specifically designed to handle rain, but it’s critical to verify this information before use.
- Inspect the Equipment: Before operation, inspect the equipment for any damage or wear. Make sure the platform is dry and free from any moisture that could lead to slipping.
- Ensure Proper Ground Conditions: Make sure that the ground is stable and level. If the terrain is too slippery, it might be better to postpone or delay the work until the conditions improve.
- Use Personal Protective Equipment (PPE): Ensure that the operator wears the appropriate PPE, including slip-resistant footwear and waterproof clothing, to reduce the risk of injury.
What Are the Safety Considerations When Setting the Location of the EWP?
Choosing a safe location for setting up an EWP is crucial to ensure the operator’s safety and prevent accidents. The location of the EWP must be carefully considered to avoid hazards such as uneven ground, unstable surfaces, and obstacles that could lead to tipping or equipment failure.
Key Safety Considerations When Setting Up an EWP
Level Ground
Always ensure the ground is level and stable before setting up the EWP. Slopes, uneven terrain, and soft or loose soil can cause the platform to tip over or lose stability. If the ground isn’t level, use stabilizers or outriggers, if the machine is equipped with them.
Check for Overhead Hazards
Before setting up the EWP, assess the area for any overhead hazards, such as power lines, tree branches, or nearby structures. Contact with overhead obstructions can result in electrocution or damage to both the platform and the surrounding environment.
Stability of the Surface
Ensure that the surface the EWP is placed on can support the weight of the machine. Avoid setting up on surfaces like gravel or dirt, as they may not be stable enough to support the heavy load.
Clearance Around the EWP
Ensure there is enough clearance around the EWP to allow for safe movement of the platform. This includes clearance from walls, buildings, and other structures that could obstruct the operator’s ability to maneuver the machine.
Wind Conditions
Avoid setting up an EWP in areas where high winds are common. Wind can significantly affect the stability of the platform and increase the risk of tipping or losing control. Always consult the manufacturer’s guidelines for wind speed limits.
Visibility and Access
Ensure that the location allows for clear visibility for the operator and that the platform can be safely accessed by workers. Poor visibility or restricted access may lead to accidents.
Use of Stabilizers and Outriggers
Many EWPs are equipped with stabilizers or outriggers. Always deploy these features to enhance stability, especially when working on sloped or uneven surfaces.

Future trends may bring about improvements in automation, electric-powered lifting equipment, and more sustainable transport solutions.
Conclusion
Both AWP and EWP are essential pieces of equipment in various industries, helping workers access elevated positions safely. However, understanding the differences between them is important for selecting the right equipment for specific tasks.
Furthermore, operating an EWP in the rain can be hazardous, and proper safety protocols must be followed when working in adverse weather conditions. Lastly, when setting up an EWP, safety should always be the top priority.
By considering the location, the ground stability, and potential overhead hazards, operators can significantly reduce the risk of accidents and ensure safe operations. Proper training and adherence to safety guidelines are crucial for maintaining a secure working environment when using elevated work platforms.
