According to BPI, what is the appropriate speed for gas sniffing at fittings?

The appropriate speed for gas sniffing at fittings is 1 inch per second. This speed is recommended to ensure accurate detection of gas leaks. Sniffing at this rate strikes a balance between being thorough and efficient, allowing the sniffing device to pick up on the presence of gas without missing any potential leaks due to moving too quickly. If a technician sniffs too rapidly, it may result in failing to detect small or slow leaks, leading to unsafe conditions. Conversely, moving too slowly can be impractical and time-consuming, limiting the effectiveness of the inspection. Thus, 1 inch per second is optimal for ensuring comprehensive safety assessments during gas leak inspections.
