Seule votre t\u00eate est lourde dans l\u2019eau.
\n<\/p>\n

    \n
  1. Immerg\u00e9 dans l'eau l\u2019hommes est en apesanteur, flottant l\u00e9g\u00e8rement la t\u00eate dans l\u2019eau. Les v\u00eatements influent peu, sauf s\u2019ils poss\u00e8dent leur propre flottabilit\u00e9 positive comme par exemple, les v\u00eatements de protection contre les intemp\u00e9ries, le froid, ou les combinaisons de survie flottantes.\n<\/li>\n
  2. Par des mouvements de natation ou par \u00abpi\u00e9tinement dans l\u2019eau", vous pouvez maintenir les \u00e9paules et votre t\u00eate au-dessus de l'eau de fa\u00e7on \u00e0 pouvoir respirer. Toutefois, il ne vous est plus possible de maintenir d\u00e9lib\u00e9r\u00e9ment votre t\u00eate en dehors de l\u2019eau en cas d\u2019\u00e9puisement ou d\u2019\u00e9vanouissement: votre t\u00eate bascule vers l'avant \u2013 et les voies respiratoires se retrouvent sous l\u2019eau.\n<\/li>\n
  3. Une flottabilit\u00e9 suppl\u00e9mentaire pourrait remplacer les mouvements de natation n\u00e9cessaires pour garder la t\u00eate hors de l'eau. C\u2019est par exemple le cas avec une aide \u00e0 la flottabilit\u00e9, comme le montre le dessin ci-contre. La flottabilit\u00e9 est ici plac\u00e9e autour du corps, surtout dans le dos et en son bas. Cela permet effectivement d\u2019\u00e9lever la personne vers le haut, mais conduit \u00e0 une amplification du mouvement de bascule vers l\u2019avant. En cas d\u2019\u00e9puisement ou d\u2019\u00e9vanouissement, ses voies respiratoires se retrouvent \u00e9galement sous l\u2019eau. C'est la raison pour laquelle une aide \u00e0 la flottabilit\u00e9 n'est pas un gilet de sauvetage! Le seul r\u00f4le de l'aide \u00e0 la flottabilit\u00e9 est de soutenir la nage active et d\u2019aider les pratiquants de sports nautiques. Une aide \u00e0 la flottabilit\u00e9 n\u2019a pas vocation \u00e0 secourir quelqu\u2019un!\n<\/li>\n
  4. Un gilet de sauvetage avec suffisamment de flottabilit\u00e9, plac\u00e9 correctement au-devant de la poitrine, autour du cou et sous le menton permet de maintenir la t\u00eate hors de l'eau en toute s\u00e9curit\u00e9. Seul un tel flotteur prot\u00e8ge la personne \u00e9puis\u00e9e ou \u00e9vanouie de la noyade. La bonne position au corps, la r\u00e9partition intelligente de la flottabilit\u00e9 autour de la t\u00eate et des \u00e9paules, ainsi qu\u2019une flottabilit\u00e9 (au moins 100 newtons) sont des caract\u00e9ristiques essentielles \u00e0 la bonne performance d'un EPI (\u00c9quipement de Protection Individuelle). Une r\u00e9serve de flottabilit\u00e9 est recommandable. La nouvelle norme EN ISO 12402 est structur\u00e9e en cons\u00e9quence: plus les exigences en mati\u00e8re de performance dans des conditions m\u00e9t\u00e9orologiques et de mer d\u00e9favorables sont grandes, plus la flottabilit\u00e9 du flotteur doit \u00eatre grande. La situation dans l'eau des naufrag\u00e9s en sera d\u2019autant plus stable et leurs chances de survie plus importantes.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
