Abstract: To address the practical issue of lacking suitable foam solutions for training and equipment testing in non-firefighting scenarios (such as daily drills) for fire rescue teams, an eco-friendly and economical foam concentrate has been developed to meet personnel training and equipment testing requirements. Test results indicate that under standard testing conditions, this product achieves a foam expansion of 8~9 times with a 25% drainage time of 4~5 min, accurately simulating the foam characteristics of fire extinguishing foam agents. Application tests using typical dispensing equipment like foam nozzles and foam monitor yielded results similar to those of fire extinguishing foam agents, further verifying the product's reliability. Additionally, this product contains no PFAS or other harmful persistent organic pollutants, demonstrates a 28-day biodegradation rate >99%, and shows a 96 h LC50 value for zebrafish exceeding 3 000 mg/L, exhibiting excellent environmental performance that significantly reduces post-use environmental risks.
