What should be done if a gas detection instrument is subjected to physical shock?

When a gas detection instrument is subjected to physical shock, rechecking its calibration is critical because physical impacts can affect the internal components and the accuracy of the instrument's readings. Calibration ensures that the instrument provides reliable and precise measurements of gas levels, which is essential for maintaining safety in potentially hazardous environments. Physical shock might displace sensors, disrupt electronic settings, or alter the baseline readings, meaning the device could deliver inaccurate data if it is not recalibrated.

Taking immediate action, such as rechecking calibration, can help identify any issues caused by the shock, ensuring that safety protocols are upheld. This step supports the integrity of the instrument's readings and maintains a safe working atmosphere, which is vital in mining operations where gas levels must be continuously monitored to prevent dangerous situations.
