Occupational safety: how aerial platforms can prevent accidents
Occupational safety is a top priority in all sectors, but becomes particularly critical when operating at high heights. Elevating work platforms (EWL), such as tracked self-propelled aerial platforms, offer a safe, efficient means of accessing jobs that require the use of equipment at height. However, as with all heavy equipment, improper use or lack of proper training can lead to serious accidents.
In this article, we will explore how aerial platforms can significantly reduce the risks of accidents at work and what measures need to be taken to ensure maximum operator safety. We will also discuss safety regulations and best practices to follow.
1. The importance of safety in work at height
Working at height involves a number of risks, including falls, rollovers, and collisions with suspended objects. According to data provided by the European Agency for Safety and Health at Work (EU-OSHA), falls from heights are among the leading causes of serious and fatal accidents in the workplace in Europe. Aerial platforms are designed to reduce these risks, but their effectiveness depends on correct use and proper operating conditions.
Safety is not only limited to compliance with regulations, but must become a corporate culture. Every operator must be aware of the risks and know how to deal with them safely.
2. How aerial platforms reduce risks
Aerial platforms, also commonly called MEWPs or man baskets, are used in various industrial sectors, such as construction, maintenance, logistics and agriculture. Thanks to their versatility, these machines allow people and materials to be lifted safely and stably. Let’s take a closer look at how they help prevent accidents.
2.1. Improved stability
Aerial platforms are equipped with advanced stabilisation systems, such as hydraulic or electronic stabilisers, which ensure a solid base during work at height. These systems reduce the risk of rollover, a major cause of serious accidents. Some modern models, such as those produced by companies like CMC, include load sensors that automatically block lifting if the maximum capacity is exceeded.
2.2. Precise movement control
Modern aerial platforms are equipped with advanced control systems that allow the operator to adjust movement with millimetre precision. This reduces the risk of collisions with surrounding structures or other workers in the area. The ability to precisely control speed and direction is essential to ensure that work is carried out safely and without accidents.
2.3. Fall protection
The aerial platforms are equipped with railings and passive safety systems to prevent operators from falling. In addition, the anchoring devices for the use of safety harnesses offer additional protection, ensuring that the operator is always connected to a safe point while working at height. The obligation to use harnesses is enshrined in international regulations, such as OSHA in the United States and European Directives.
2.4. Operator training
One of the most important aspects of accident prevention is the proper training of operators. Aerial platforms require a well-informed use and a thorough understanding of the machine’s functionalities. Companies such as CMC offer training courses for operators, so that they are able to use the platforms safely and react promptly in the event of an emergency. The training covers several aspects, including machine operation, risk management and emergency procedures.
3. Safety regulations and rules
Safety in the workplace with aerial platforms is regulated by international and national regulations that define the standards of use and maintenance. Some of the most important are:
3.1. The Machinery Directive 2006/42/EC
The Machinery Directive 2006/42/EC lays down the essential safety requirements for the design and construction of machinery in Europe. Aerial platforms must comply with this directive in order to be marketed and used within Europe. Among the main provisions are the obligation to install safety systems against falls and to guarantee the stability of the machine.
3.2. OSHA (Occupational Safety and Health Administration) regulations
In the United States, OSHA regulates workplace safety, with a focus on work at height. OSHA regulations require operators be properly trained and machines to be inspected regularly. In addition, OSHA requires the use of personal protective equipment, such as safety harnesses, when working on aerial platforms.
3.3. Periodic maintenance and inspections
Aerial platforms must undergo regular inspections to ensure they are in safe operating condition. The regulations establish the frequency of inspections and checks to be carried out. For example, the inspections must include the checking of hydraulic systems, stabilisation sensors, support structures and safety devices. Preventive maintenance is essential to avoid unexpected malfunctions that could cause accidents.
4. Good practices for the safe use of aerial platforms
In addition to regulatory compliance, there are a number of good practices that operators and safety managers should adopt to minimise the risks associated with the use of aerial platforms.
4.1. Work planning
It is essential to plan the operation carefully before starting any work at height. This includes identifying hazards, choosing the appropriate aerial platform based on job requirements, and checking environmental conditions, such as wind and terrain. The proper planning of work reduces the risk of surprises and operational errors.
4.2. Use of PPE (Personal Protective Equipment)
Operators of aerial platforms must always wear personal protective equipment, such as helmets, harnesses and gloves. Even if aerial platforms are equipped with safety systems, PPE provides additional protection in case of emergencies. It is essential that operators are trained on how to wear these devices correctly and how to react in the event of a platform malfunction.
4.3. Pre-operational inspection of the machine
Before using an aerial platform, operators must perform a pre-operational inspection to verify that all components are functioning properly. The main controls include the operation of the brakes, condition of the tyres or tracks, level of the hydraulic oil and integrity of the safety devices. A careful check before use can prevent many accidents caused by mechanical failures.
4.4. Clear communication
During operations at height, it is essential to maintain clear communication between operators and ground personnel. The use of visual or radio signals can prevent accidents resulting from misunderstandings or unexpected movements of the platform. Good team coordination is essential to ensure that the operation is carried out safely.
5. Technological innovations for greater safety
In recent years, the aerial platform industry has introduced several technological innovations to improve operator safety. These include:
5.1. Remote monitoring systems
Some models of aerial platforms are equipped with remote monitoring systems that allow you to check the status of the machine in real time and detect any anomalies. These systems offer greater safety, as they allow safety managers to intervene promptly in the event of malfunctions.
5.2. Anti-collision sensors
The most advanced aerial platforms are equipped with anti-collision sensors that detect obstacles in the vicinity and automatically block the movement of the machine. This technology is particularly useful in confined environments or on crowded construction sites, where the risk of collisions is greater.
5.3. Self-levelling systems
Some aerial platforms are equipped with self-levelling systems, which automatically adjust the inclination of the machine to ensure a stable base even on uneven terrain. This technology significantly reduces the risk of rollover, especially on construction sites with challenging surfaces.
