What is a critical characteristic of an abrasive spray material?

An abrasive spray material is defined by its physical properties, which can necessitate the use of specialized handling equipment. This is primarily due to its composition, which often includes materials that can wear down standard equipment, potentially causing damage or inefficiency. The abrasive nature means that conventional spray systems may not withstand the physical stress that these materials can impose, leading to the requirement of upgraded or specific equipment designed to handle such substances.

In contrast, other characteristics such as viscosity or corrosiveness, while significant in their own rights, do not inherently define the abrasive quality of the material. Using large volumes can be a practical consideration in certain applications, but it does not categorize the material as abrasive nor highlight the challenges in handling it. The characteristic that specifically signals a need for special equipment aligns closely with the inherent risks and demands associated with an abrasive spray material, making this the standout choice.
