A Mobile Elevating Work Platform (MEWPs) is a powered machine designed to provide temporary access for people and equipment to work at height. MEWPs are integral to various industries, such as construction and manufacturing.
Their ability to elevate workers safely and efficiently makes them essential for tasks that would otherwise require scaffolding or ladders.
Common Applications of Mobile Elevating Work Platforms (MEWPs)
MEWPs are versatile and come in various types that serve different purposes in a worksite.
For example, Scissor Lifts are used to extend vertically and are ideal for tasks that require access directly above the platform. It is often used for installing overhead piping or electrical fixtures on ceilings in high-rise construction projects.
Boom Lifts are Mobile Elevating Work Platforms providing both vertical and horizontal reach, allowing workers to access areas that are hard to reach, such as around obstacles. It is ideal on a factory floor for accessing large machinery or installing equipment on high platforms.
Vehicle-Mounted Lifts are MEWP specializing in mobility across different sites. It is quite handy for outdoor maintenance tasks or installations in multiple locations.
Spider Lifts are used indoors or on uneven terrain due to their flexible legs and are used in manufacturing and construction sites for indoor repairs of machinery in tight spaces or on multi-level platforms where maneuverability is crucial.
While the tasks accomplished by these MEWPs seem routine, there are several Mobile Elevating Work Platform Safety concerns associated with it that are constantly looked upon by the EHS teams.
Let’s dive into a recent safety breach in MEWP use that led to fatality!
On November 22, 2024, a worker at a construction site in East Tung Chung, Hong Kong was working on a Mobile Elevating Work Platform. In between his lift, he was trapped between the lift platform itself and the beam overhead. This led to his death due to entrapment when using the Mobile Elevating Work Platform (MEWP).
This raised serious concerns among the Construction Industry Council (CIC) which immediately set out mandatory safety instructions for operating MEWPs on worksites.
Any public works contract whether for capital works or maintenance on or after 29th November, 2024 must have a Secondary Guarding Device (SGD) for MEWP. While it could be in the form of physical barriers or a smart device, but in this world of technology, an AI-powered SGD can be the only best solution.
Before diving into the latest MEWP safety standards, let’s explore the leading causes behind MEWP-related incidents.
Mobile Elevating Work Platform Safety Concerns
Mobile Elevating Work Platforms (MEWPs) are essential for tasks at height but carry significant risks if safety protocols are not followed. Several MEWP safety issues govern the workers engaged in its task.
1. Falls from Height – It is one of the most common hazards in MEWP safety operations which can result from improper use of safety equipment or sudden movements.
Workers may fall due to improper use of guardrails, overreaching, or failing to wear a harness. It must be made sure that workers are tethered to anchor points with properly adjusted harnesses, with no missing barricades during operation to prevent accidental falls.
2. Electrocution - Working near overhead power lines or electrical installations increases the risk of electrocution.
For example, a maintenance worker could accidentally extend a boom into a live wire if safety protocols are not followed. Maintaining a minimum clearance distance from power lines and using insulated MEWPs can significantly reduce this risk.
Additionally, site-specific hazard assessments should be conducted to identify potential electrical threats before starting work.
3. Entrapments – The recent accident in Hong Kong is an example of how entrapments between MEWPs and external structures cause fatal accidents.
This hazard often arises in confined spaces or when operators maneuver without sufficient visibility. Installing secondary guarding devices (SGD) in the form of added physical barriers or smart AI-powered safety management systems that detect proximity to obstacles can help prevent such incidents.
4. Overturns and Collisions - MEWPs can overturn if operated on unstable ground, overloaded, or used improperly. For example, a MEWP might tip over if it is positioned on sloped terrain without deploying stabilizers.
Ensuring the ground is level and stable is critical before operation. Operators must deploy outriggers when necessary and adhere strictly to load limits. Routine inspections and using MEWPs with automatic levelling systems can also minimize the risk of overturns.
Proper load distribution and securing materials on the platform are essential to prevent sudden shifts that could destabilize the equipment.
In busy worksites, MEWP safety is at risk of colliding with other machinery or vehicles, such as forklifts or cranes. This risk is particularly high in manufacturing plants and logistics hubs where multiple vehicles operate in close proximity.
Installing proximity sensors and using AI video analytics can alert operators to nearby obstructions.
5. Mechanical Failures - Issues such as hydraulic malfunctions, brake failures, or sudden power loss can result in catastrophic accidents.
For example, a scissor lift might collapse if its hydraulic system fails during operation. Regular maintenance and thorough pre-use inspections are crucial in identifying potential issues before they become critical.
Predictive maintenance, powered by AI in MEWP safety, can analyze operational data and predict failures, allowing for timely repairs.
Whether it is detecting an obstacle around the Mobile Elevating Work Platforms (MEWPs) or alerting the HSE teams immediately in case of a safety breach, the only modern-day solution that can ensure workplace safety is the use of AI in MEWP safety.
