Area of Science:

  • Fire Safety Engineering
  • Respiratory Protection
  • Foam Technology

Background:

  • Protein-based foams are effective fire suppressants.
  • Occupant safety in foam-filled environments, such as high-rise buildings and ships, requires breathable air solutions.
  • Existing methods for providing air in such scenarios are limited.

Purpose of the Study:

  • To develop a method for providing breathable air to individuals trapped in protein foam environments.
  • To adapt existing respiratory protection equipment for use with fire-extinguishing foams.

Main Methods:

  • Design and construction of a canister attachment for standard gas masks.
  • The canister is engineered to break down incoming air-filled protein foam.
  • Integration of the canister with a gas mask to filter foam and supply breathable air.

Main Results:

  • Preliminary testing demonstrates the feasibility of breathing through air-filled protein foam using the modified mask.
  • The designed canister effectively processes foam to allow air intake.
  • The modified gas mask system shows potential for providing a life-support function.

Conclusions:

  • The developed gas mask modification offers a viable solution for respiratory protection in protein foam-filled environments.
  • This innovation could significantly improve survival rates for individuals trapped in fires utilizing protein foam suppression.
  • Further research and development are warranted to optimize the system for widespread emergency use.
