Why are the results provided by on-site gas sensors inaccurate?
A gas analyzer that operates normally is an important component of any facility's safety and health policy. This is especially true when people consider the danger caused by the accumulation of undetected combustible gases, which typically leads to fires or explosions, thereby damaging or damaging the entire facility. Therefore, determining why gas analyzers cannot provide accurate readings is a core part of any comprehensive workplace safety plan. If the gas analyzer does not provide accurate readings, in addition to potential legal issues that may arise, it also poses a significant risk to both the facility and employees. However, it is important to determine why the analyzer did not provide accurate results in order to find an effective solution.
Poor position
To be effective, the placement of the gas analyzer needs to make the surrounding atmosphere a characteristic of the entire area to be protected. Improper placement may damage the target. For example, placing the analyzer near the door may result in inaccurate readings due to the mixing of indoor air and external space air. Similarly, placing the analyzer near an area that typically emits flammable gases may result in a higher reading than the combustion chamber. Therefore, gas analyzers should be placed in areas exposed to average gas levels, rather than areas where extreme situations may occur in any direction.
Poor calibration
An important part of installing and maintaining gas sensors is correct calibration. Correctly calibrated sensors themselves are not just simple and accurate. They can contribute to the overall information generated by gas sensor networks regarding facilities. Therefore, it is necessary to regularly calibrate each sensor and provide training and evaluation for employees to correctly calibrate all sensor types that will be used in the factory. In addition to its other advantages, regular calibration of sensors can also help facilities detect sensors that need to be replaced. The discovery of multiple sensors, especially newly installed sensors, with incorrect readings usually indicates that the company's calibration policy needs to be reviewed.
Poor maintenance
When major faults occur at the workplace, those who perform improper or delayed maintenance are usually unknown. It is important to maintain a regular sensor maintenance plan and promptly repair or replace sensors that have not passed inspection. In addition, if the number of sensors that require repair or replacement unexpectedly increases, management should immediately determine the root cause. In some cases, these issues may be the first signs of more severe malfunctions occurring within the facility.
Gas analyzers are the first line of defense against potential hazards of toxic or flammable gases. By ensuring the normal operation of the facility's analyzer network, potential hazards to physical factories, facility employees, and surrounding communities can be eliminated. Therefore, management and its employees should always consider maintaining any gas analyzer as a top priority.
