Colorized Vermiculite Fire Suppression Agent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solid particle fire suppression agents are difficult to visualize against similarly colored compartment surfaces, such as those found in aircraft cargo holds, making clean-up after discharge or in case of a leak challenging due to their beige, white, or brown color.
Innovation Solution
A fire suppression agent incorporating vermiculite particles and a powderized colorant, such as vivid dyes or pigments, to enhance visibility, with the vermiculite particles being effective against class D, A, B, and C fires, and the colorant particles loosely or tightly associated with the vermiculite to prevent interference with fire suppression capabilities.

Engineering Contradiction Analysis
1Illumination intensity
If a fire suppression agent uses traditional beige, white, or brown particles, then the fire suppression performance is effective, but the visibility of particles against compartment surfaces is poor
Solution Approach 1:
The patent combines traditional fire suppression particles (such as metal powders for Class D fires) with colorant particles to create a composite fire suppression agent. The colorant particles are incorporated into the formulation at concentrations of 0.1% to 5.0% by weight, creating a multi-component system that provides both fire suppression functionality and enhanced visibility through color differentiation from background surfaces.
2Ease of operation
If a colorant is added to enhance visibility, then the visibility and ease of clean-up improve, but the fire suppression performance may be compromised
Solution Approach 1:
The colorant particles are applied in localized quantities (0.1% to 5.0% by weight concentration) rather than uniformly throughout the formulation. This localized addition ensures that the color enhancement function is achieved without significantly altering the bulk properties and fire suppression performance of the primary agent particles. The colorant serves a specific local function of visibility enhancement while the majority of the formulation maintains its fire suppression capabilities.
Solution Approach 2:
The patent carefully controls the concentration parameter of the colorant within a specific range (0.1% to 5.0% by weight) to optimize the balance between visibility enhancement and fire suppression performance. By adjusting this parameter, the formulation achieves sufficient color intensity for visibility and ease of clean-up while maintaining the effective fire suppression properties of the primary agent particles.

AI summary
A fire suppression agent includes a fluid medium, vermiculite particles suspended in the fluid medium, and a colorant additive proximate at least a subset of the vermiculite particles. The fire suppression agent is capable of suppressing a fire comprising a combustible metal material.
