Our San Antonio H2S Monitors are factory calibrated to last for two years. After they are started new, the monitor starts a 24 month countdown. Once the countdown is finished then the monitor alerts that it is expired and then turns off. After these H2S monitors expire they can not be recalibrated or reset and a new monitor must be obtained for proper protection. Calibration, however, is not the only reason that a monitor may need to be replaced.
H2S monitors also need to have fresh batteries to work properly. The installed battery is sufficient to keep the monitor on for its two-year lifetime. Prior to starting the H2S monitor the battery will begin to age. This means that the monitor must be started before the start-by date listed by the manufacturer.
Dirt and damage may also cause an H2S monitor to fail. Although they are built for rugged use they are not to be abused. The air inlet must also be left clear and clean. Obstructing the inlet with clothing or other blockages prevents the air from entering and giving the sensor a proper sample. The inlet filter should not be allowed to saturate with oil or dirt. Regular bump testing is an important part of monitor maintenance to ensure that the device continues to function properly.
H2S personal monitors are designed to detect small amounts of hydrogen sulfide that are hazardous to human health. High concentrations of H2S (such as above 100ppm) can fatigue the sensor and potentially damage the equipment. New San Antonio H2S monitors indicate this with a feature that shows the highest monitor reading within the last 24 hours. Only use H2S monitors within the listed manufacturers specifications. Never misuse a personal H2S badge by attempting to read from a concentrated source such as by lowering it into a confined space or placing the sensor in front of a vent line.
How do you know that your H2S monitor still works? Regular bump testing uses a small stream of calibrated hydrogen sulfide gas in order to test whether the sensor responds within the proper timeframe. The high and low alarms must sound after the gas makes contact with the sensor. Always follow the manufacturers recommendations for a regular bump test program. These H2S monitors also have a function test that should be performed daily. To perform the function test the worker depresses the function button and observes the function of the LCD screen, visual and audible alarms, as well as the unit vibration alarm. Never use a monitor that fails to alarm properly and never ignore an alarm while in the field.
If you are in need of a new badge then purchase a new H2S monitor in San Antonio. The Eagleford Store sells monitors including a free bump test in order to help prove that workers are obtaining proper protection. Hydrogen sulfide is a deadly gas and all are reminded to avoid worker contact and treat it with the greatest precaution.
