Idivayisi yokuphonsa esindisa impilo (ephathekayo, epakishwa njengesikhwama segalofu) Asikho isidingo somthombo womoya wangaphandle ukuze usindiswe ngokushesha, ifakwe igeyiji yokucindezela komoya.

Amapharamitha ayisisekelo:
1. Ukusebenzisa i-CO2/umoya ocindezelwe, ingcindezi yokusebenza: 5-7 MPa, isisindo esiphelele ≤ 7.5KG, isisindo esiphonsayo ≤ 1.5KG.
2. Ibanga lokuphonsa: Ibanga lokuphonsa ngamanzi lama-lifebuoys azenzakalelayo afuthwayo ≥ amamitha angu-80-100, ibanga lokuphonsa phansi lingafinyelela kumamitha ayi-100-120.
3. Imininingwane yentambo yokuphonsa: Φ3mm × 110/100/ izinhlobo ezimbili zezintambo zokuphonsa, amandla azo okudonsa angaphansi kuka-2000N. Ama-projectile okutakula, izintambo zokutakula kanye nemikhono yokuvikela amanzi kungasetshenziswa kabusha.
4. Isikhathi sokundiza emoyeni: imizuzwana emi-3-5. Ama-projectile okutakula asekelwe emanzini angena ngokuzenzakalelayo abe ama-lifebuoy zingakapheli imizuzwana emi-5 ngemva kokungena emanzini, akhiqize amakhilogremu angaphezu kuka-8 okuntanta.
5. Ukusebenzisa i-CO2 engama-33g noma isilinda sokuphefumula komoya njengamandla okuqalisa, akukho ilangabi elivulekile. Lingadutshulwa noma lingene endaweni evuthayo lisuka endaweni evuthayo.
6. I-thrower ephathekayo ilula, iyashesha futhi ilula ukuyisebenzisa. Ngesikhathi sokutakula ensimini, akukho mthombo womoya wangaphandle odingekayo. Ingaphonswa futhi isindiswe nganoma yisiphi isikhathi, okusindisa isikhathi sokutakula esiyigugu futhi kuthuthukiswe ngempumelelo ukusebenza kahle kokutakula.
7. Umzimba wesilinda womjikijolo uhlonyiswe ngesilinganiso somfutho womoya, esingabonisa ngokucacile inani lomfutho womoya ngaphakathi komjikijolo ngesikhathi sokusetshenziswa, kugwenywe umfutho wokungena ngokweqile noma onganele ongathinta umphumela wokusetshenziswa. Kuphinde kuqinisekise ukuphepha komsebenzisi.
8. I-phoster ephathekayo ifakwe idivayisi yokukhipha intambo ukuze idonseleke entanjeni, engabuyisa ngokushesha intambo yokutakula futhi ithuthukise isikhathi sokutakula kanye nokusebenza kahle.
9. I-thrower ephathekayo inezici zobukhulu obuncane, isisindo esincane, kanye nokuhlanganiswa okulula. Iphakheji iyiphakheji yangaphandle efana nesikhwama sebhola legalofu, engathwalwa futhi ithwalwe. Kulula ukuyiphatha futhi ilungele abasebenzi bokuhlenga abangena ngokushesha endaweni yokuhlenga futhi baqale ngokushesha umsebenzi wokuhlenga.
10. Lo mjikijeli unezindlela ezimbili zokuphonsa: A: Isilinda somoya esincane esingu-33g esigcwaliswe ngqo ukuze siphonse.
B: Iqembu lamapayipi anomfutho ophezulu elixhunywe kusilinda sokuphefumula emoyeni ukuze kukhuphuke umoya futhi kuphonswe.
Uhlu lokucushwa:
Ukucushwa okujwayelekile kwephrojektha ephathekayo kungokulandelayo: isethi eyodwa yezingxenye eziyisisekelo zokuqalisa, ama-projectile amabili okusetshenziswa komhlaba (aqukethe intambo yokutakula yamamitha ayi-110), ama-projectile amabili okusetshenziswa kwamanzi (aqukethe intambo yokutakula yamamitha ayi-100), i-projectile eyodwa yokuqeqesha, i-impactor eyodwa, isethi eyodwa yamapayipi anengcindezi ephezulu enezinjongo ezimbili, ithubhu elifushane lokuqalisa, izikhwama zezintambo ezimbili (esinye sazo siqukethe intambo engu-110m), amasilinda amane e-CO2 angu-16-gram, amasilinda angu-8 e-CO2 angu-33g. Ama-igniter angu-4, isethi eyodwa yesembozo sokuvikela amanzi, isethi eyodwa yamasongo okuvala avamile, iphakheji eyodwa yesitayela sesikhwama segalofu.
