Aerial platform trucks provide the department with an extremely powerful tool for rescue, ventilation, and extinguishing fires.
All Fire Apparatus Manufacturers’ Association (FAMA) member companies are concerned with firefighter safety, and those that produce products that lift people into the air are particularly sensitive to promoting safe practices. This article will discuss the issue of platform safety, focusing on the aerial device itself and its operational characteristics.
Emergency Vehicle Standards
Because of their tremendous capabilities and working heights, elevating platform devices are highly engineered products that must be strong but lightweight. As a result, the vehicles on which the aerial platform devices are installed are complex and require skill and training to use them effectively. The key parameters regarding structural safety factors, truck stability, and many more key requirements are covered in detail in the 2016 edition of National Fire Protection Association (NFPA) 1901, Standard for Automotive Fire Apparatus. The latest edition includes several changes that affect aerial platform design. The FAMA Apparatus Safety Guide is also an excellent source of information regarding aerial apparatus safety.
Preparation and Training
As a young engineer, I was involved in the design of tower cranes and marveled at the operators’ ability to lift heavy construction materials at great heights and precisely place the material to the workers above. The operators appeared to be experienced and well-trained, understood the equipment, and had tremendous skills. Much like the tower crane operator, the aerial platform operator should have this level of understanding, training, and skills.
Because of the versatility and capability of platform aerials, it is critical that you read and understand the operator’s manual. You should complete a comprehensive study of the manual and have a thorough knowledge of operating instructions, control systems, load capacities, safety precautions, and limitations. It is important to understand the capabilities of your unit, because vehicle capabilities change as technology develops and also change from manufacturer to manufacturer.
The experienced operator should avoid complacency and always keep focus on the task at hand. If you are new to the truck, make sure you find the original manual information to review and work with an experienced trainer to understand the device.
Platform operations
Fireground scenarios naturally create a stressful environment; use your training and practice time to become confident in your abilities at the scene. Give your undivided attention to the aerial during operations; if distracted, stop operations.
In recent years, the technologies used in platform control systems have advanced considerably. These advancements can improve both the controllability and the safety of a platform. For example, it is very common to have joysticks that have ramping characteristics that smooth out abrupt starts and stops. However, the ramping feature may be different from truck to truck, and older units will likely not have the feature at all. It is important to understand the control system of the specific truck.
Another example of technological enhancement is controlling platform speeds based on aerial position. An extended platform rotating at high elevation angles moves at a relatively low speed. However, with the extended ladder rotated at low angles at the same speed, the platform will move with high speeds relative to the ground. This can be as high as 10 feet per second. At these speeds, use extr
