How long can I wear the badge?

You can wear the badge continuously for up to 12 hours. However, the badge is designed to measure up to a maximum 400 ppm-hr. integrated exposure. If the H₂S concentration in the environment is excessively high, the badge can saturate before 12 hours. For example, if the concentration of hydrogen sulfide gas is constant at 100 ppm, then the badge will saturate in 4 hours. Use the Pocket Viewer to check your exposure frequently if you are concerned the hydrogen sulfide concentration may be excessively high.
