What is commonly used to mark designated lengths on ladders?

Metal tags are commonly used to mark designated lengths on ladders for several reasons, primarily related to durability and visibility. These tags are typically made of robust materials that can withstand exposure to various environmental conditions without fading or eroding. This ensures that the markings stay legible over time, even in harsh conditions that fire services may face.

Furthermore, metal tags can be securely attached to the ladder, making them less likely to be inadvertently removed or damaged compared to other marking methods. The use of metal tags also conforms to safety standards, ensuring that each ladder is easily identifiable and compliant with operational protocols, which is essential for the safety and efficiency of firefighting operations.

In contrast, stickers may not adhere well under extreme temperatures or could wear off with time, paint could chip or fade, and inscriptions might not be as prominent or durable as metal tags. Hence, metal tags are the most reliable choice for marking designated lengths on ladders used in firefighting.
