What are Aerial Lifts?
Aerial lifts, often seen as the backbone of shipyards , Laydowns, Material Storage yards and boatyards etc. Aerial lifts are specialized equipment designed to elevate workers to heights where traditional staging might be impractical. These include boom-supported personnel platforms and bucket trucks, colloquially known as cherry pickers.
Importance of Aerial Lift Safety
In the dynamic environment, where tasks overlap and urgency is a constant, the safety of workers on aerial lifts is paramount. This article aims to shed light on the intricacies of aerial lift safety, emphasizing the potential dangers, best practices, and essential guidelines.
2. The Dangers of Aerial Lifts
Common Causes of Injuries and Deaths
The utility of aerial lifts is undeniable. However, they have been linked to numerous worker injuries and fatalities. Incidents range from boom failures and tip-overs to falls and unexpected ejections. While equipment malfunction is a culprit, human error, inadequate training, or oversight often exacerbate these risks.
The Impact of Boom Failures and Tip-Overs
A malfunctioning boom can spell disaster. When it fails, the elevated platform can collapse, endangering any worker atop. Tip-overs, influenced by factors like unstable terrains, gusty winds, or proximity to open edges, are equally perilous.
3. Essential Safety Measures Employers Must Adopt
Providing Safe and Well-maintained Equipment
Safety begins with the equipment. Employers bear the responsibility of ensuring that aerial lifts are in pristine condition. Regular maintenance checks are non-negotiable. Any irregularities, be it wear and tear or malfunctioning components, warrant immediate attention.
The Imperative of Proper Supervision and Training
Training is the cornerstone of safety. All personnel, whether operating the lifts or working in their vicinity, must undergo comprehensive training. This encompasses equipment operation, safety protocols, emergency response, and risk mitigation.
The Non-negotiable: Fall Protection Equipment
Every worker on an aerial lift should be equipped with fall protection gear. This includes a body harness and a lanyard, anchored securely. This simple measure can prevent potential falls, ensuring worker safety even in precarious situations.
4. Safe Work Practices for Aerial Lifts
The Golden Rule: Always Tie-Off
The importance of tying off cannot be overstated. It’s a simple, yet crucial action that can be the difference between a regular day at work and a tragic accident. Regardless of the height, the mandate is clear – always tie-off.
Harnessing Safety: Proper Use of Body Harness and Lanyard
Merely having safety equipment isn’t enough; using it correctly is key. Workers should be adept at wearing the body harness and securing the lanyard to a reliable anchorage point.
The Cardinal Sin: Moving the Lift with Workers Elevated
Moving the lift while workers are elevated is a grave risk. Such an action can lead to catastrophic accidents, from tip-overs to workers being jolted off balance. It’s a risk that’s unwarranted and avoidable.
5. Training and Operation
Training Operators for Safe Equipment Operation
Every aerial lift operator should undergo rigorous training. This training should not only focus on the technical aspects of operating the lift but also on understanding the potential risks and how to mitigate them.
Adhering to Manufacturer’s Instructions
Every piece of equipment comes with a set of manufacturer’s instructions. These guidelines are crafted based on extensive testing and understanding of the equipment. Ignoring them can lead to mishaps. It’s imperative that operators familiarize themselves with these instructions and adhere to them.
Importance of Properly Marked Equipment Controls
Clearly marked equipment controls eliminate guesswork. In a high-risk environment, clarity can prevent accidents. Employers should ensure that all controls are legible, accessible, and understood by the operators.
6. Safety Devices and Their Significance
Dangers of Overriding Safety Devices
Safety devices are integrated into aerial lifts for a reason. They act as the last line of defense against potential mishaps. Overriding or tampering with these devices can lead to unintended movements or malfunctions, putting workers at risk.
Understanding the Lift’s Movement on Barges
When operating a lift on a barge, operators should be acutely aware of the list, trim, and lash down points. The aquatic environment introduces additional variables, and understanding them is crucial for safe operation.
7. Preventing Accidents Near Open Edges
Using Stops for Enhanced Safety
Stops can prevent the aerial lift from moving inadvertently, especially when near open edges. These simple devices can prevent tip-overs and ensure the lift remains stationary when required.
Awareness of the Swing Radius
Every aerial lift has a swing radius. Operators should be well-versed with this radius to ensure the lift doesn’t collide with nearby structures, equipment, or personnel.
8. Safety Tips When Elevated
Dangers of Getting Between Structures and the Lift
When elevated, workers should be cautious not to position themselves between the lift and any structure. Any inadvertent movement could lead to crushing or pinning, resulting in severe injuries.
How Movement Can Lead to Crushing
The aerial lift, especially when elevated, should be operated with utmost caution. Any unexpected movement, swing, or shift can lead to workers being crushed against structures or other obstacles.
9. Preventing Tip-Overs
Setting Brakes and Using Wheel Chocks
Before elevating the platform, it’s essential to set the brakes. Additionally, using wheel chocks can prevent the aerial lift from moving, especially on inclined surfaces or uneven terrains.
Checking Tire Pressure and Extending Outriggers
Maintaining the correct tire pressure is crucial for stability. Low tire pressure can lead to an unstable base. Outriggers, when extended, provide additional stability, especially when the lift is elevated to significant heights.
Ensuring the Lift is Level
Before elevating, operators should ensure that the lift is level from all sides. An uneven base can lead to tip-overs, especially when the platform is raised.
Weather and Environmental Considerations
High winds can destabilize the lift. Operators should be trained to assess environmental conditions and avoid operating the lift in adverse weather, especially during high winds.
10. Understanding Personal Flotation Devices (PFD)
Limitations of PFDs in High Falls
While PFDs are essential when working over water, they have their limitations. A fall from a significant height, even into water, can lead to severe injuries. PFDs won’t mitigate the impact of such falls. Hence, tying off remains crucial.
The Importance of Tying Off
Tying off ensures that even if a worker loses balance or there’s a tip-over, they remain secured to the lift. It’s a simple measure that can prevent fatal falls.
11. Risks Associated with Lifting and Moving Objects
Dangers of Using Aerial Lifts for Lifting
Aerial lifts are designed to elevate personnel, not to lift heavy objects. Using them for lifting can lead to overloading, resulting in tip-overs or collapses.
Understanding Load Capacity and Its Implications
Every aerial lift has a specified load capacity. This capacity includes the weight of the worker, tools, and any other materials on the platform. Exceeding this capacity can lead to catastrophic failures.
12. Statistics and Real-life Incidents
Analyzing Fatal Falls from Aerial Lifts
Half of all fatal falls from aerial lifts occur when workers aren’t tied off. Such statistics highlight the importance of adhering to safety protocols.
The Role of Improper Set-Up and Operation
Improper set-up or operation accounts for a significant number of aerial lift accidents. Such incidents underscore the importance of training and adherence to manufacturer guidelines.
13. OSHA Guidelines and Recommendations – Aerial Lift Safety
Lifting Heavy Objects and Load Capacity
OSHA guidelines emphasize the dangers of lifting heavy objects using aerial lifts. Adhering to these guidelines can prevent accidents and ensure worker safety.
Understanding the Risks of Basket Hang-Ups
Basket hang-ups can lead to tip-overs or collapses. Operators should be trained to recognize and mitigate the risks associated with such hang-ups.
Safety should never be compromised. In the dynamic environment of shipyards, where aerial lifts play a pivotal role, ensuring the safety of workers is paramount. Through continuous training, adherence to guidelines, and the use of safety equipment, accidents can be minimized, ensuring a safe and productive workspace.
