Monitoring Hydrogen Sulfide (H S) 2 to meet new exposure .

Where there is potential exposure to Hydrogen Sulfide, a monitoring strategy is recommended to ensure exposures are kept below acceptable levels and standards and that appropriate action is taken when there are excursions above these levels. Either traditional IH monitoring methods or electronic instruments can be used for this purpose.
