What is the purpose of the soap bubble solution in fire investigations?

The purpose of the soap bubble solution in fire investigations is primarily to locate leaks in a pressurized system. When applied to areas suspected of having leaks, the soap bubbles will form and expand, making it visually apparent where gas or liquid is escaping. This is particularly important in incidents involving flammable gases or contents under pressure, as identifying leaks can help investigators assess the potential for further hazards and facilitate a safer investigation.

In fire investigations, being able to quickly and accurately pinpoint the source of leaks is essential for determining the origin of the fire and any factors that might have contributed to its development or spread. This method is efficient and effective for both gas and liquid leaks, playing a critical role in the overall safety and integrity of the investigation process.
