Paragraph starter

The integration of phase change materials (PCMs) into firefighter protective clothing (FFPC) presents a significant opportunity to enhance thermal performance. Research by Lee K. McCarthy (2010) demonstrated that PCMs effectively absorb heat during their phase transition, leading to a reduction in the temperature experienced at the skin surface. This finding suggests that incorporating PCMs into protective garments can improve user safety and comfort in high-temperature environments.
