        SUBJECT: Hydrogen Sulfide (H2S) (U)

        1.         PLLt-POSe. To provide info on the hydrogen Sulfide (H-@S)
        threat  in the fl.L(viaiti theater of operations.

        2. (U) Facts.

             .1 a.,    Ail 0-F i'LLVJait'S oilfields  contain @arious-.I,evL-le of
        H2S which could present adverse effects to Liriprntecteli
        per-. sorin e Iin the event c)-F uncontrolled wellhead explosions, a
        threat to   personnel safety e,@ists.

             b. @ H2S is a cloudless, flammable and to@,ic compound
        ki-sown to provide a. full range of effects On Ltnpr-lotE-cted
        personnel. Primarily -=t respiratory hazard, H2S in low
        concentrations can cause irritation to the eyes and mucus
        nembr,@nes of the nose, mouth and throat. In higher
        concentrations the ga.5 has the distinct smell of "rotten eggs"
        and                                                     The gas is
             can C@Ltt;e death +or unprotected personnel.
        heavier than air and disperses at cirr@L-tnd level.

             C." @     The L>@plosivL, characteristics OF K2S -:%re an
        additional cause of concern. E,,,,plosive limiti$@@f H2S in the ai.-
        -ire
             si,milar to gasoline. Ignition of the gas pilll most likely
        only, come- from, afi e@ct@-rnal cate.1 yst due to the hi q@ temperatures
        required (500 deg r@ahrenhgit) -For spontaneous@c;ombttFtion.

             d.        Prior to operating in areas of t,nown H2@D coi-icc-n@,rA-
        tion, personnel should don the protective mast,..        H2S is not a
        protective fnas@.. penetralor. Protective mas@, filters will
        protect against H2S penetration for the life of the filter.
Personnel can e),,pect to detect the rotten egg smell associated
        with        thus indicating the need to replace -Filters.

             e.        Iraqi troops are assessed to have the ability to
        protect themselves against F12S. Soviet/Warsaw Pact or-otectivl-
        fnasl..-.s in the Iraqi inventory provide protection agai@at H2S.
