🔥 Wool vs Synthetic – Flammability Test When these two carpets were exposed to fire, the difference was dramatic: Wool ignites at 570–600°C Synthetics ignite at just 200–300°C Wool chars and self-extinguishes Synthetics melt, burn fast, and release toxic fumes Flashover is the point in a fire when a room’s contents all ignite almost simultaneously, creating a fully developed blaze. In modern homes with synthetic furnishings, flashover can happen in under 5 minutes – and in some cases as little

Here's an A2L refrigerant flame test vs A3 flammability. You can see there is a major difference. For reference R32 and R454B carry the A2L classification. R410A is an A1. #hvac #hvactechnician #HVACTech #hvaclife | Tony Mormino
