Ana hatari gani kwa watu?

Hatari kwa watu: HafifuKama kudungwa na nyuki au chini ya hapo. Kimsingi hana madhara kwa watu.

Akiuma

Kubana na kutotikisa: funga bandeji nyororo kwa nguvu juu ya jeraha kisha mguu au mkono mzima, weka banzi, na umweke mtu bila kutikisika kabisa hadi msaada ufike.
Pweza mwenye pete za bluu au konokono koni anaweza kusimamisha pumzi ya mtu akiwa bado ana fahamu: omba msaada na uwe tayari kumpa pumzi ya uokoaji hadi gari la wagonjwa lifike.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikuuma: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama
