What is indicated by the placement of cribbing during aerial operations?

The placement of cribbing during aerial operations primarily serves to provide support and stability to the apparatus. This is crucial in ensuring that the aerial device remains secure and balanced while operating at various heights and angles. Proper cribbing can prevent tipping or shifting, especially on uneven or unstable ground, thereby enhancing the safety of both the firefighters operating the equipment and the individuals they are working to save.

By elevating and stabilizing the apparatus, cribbing helps to distribute the weight appropriately and allows for better operation of the aerial ladder or platform. This is especially important in emergencies where conditions may be unpredictable, and maintaining control is vital for effective firefighting and rescue efforts.
