LES PERSONNES QUI ONT REMPLI<\/span><\/strong> Les personnes qui utilisent des bouteilles de plong\u00e9e, qui remplissent des bouteilles d'oxyg\u00e8ne ou qui augmentent le m\u00e9lange de gaz sont habitu\u00e9es \u00e0 utiliser des tuyaux flexibles. Certains tuyaux sont recouverts d'une gaine durable en caoutchouc ou en thermoplastique, tandis que d'autres semblent encore plus robustes avec un filet tress\u00e9 en acier inoxydable \u00e0 l'ext\u00e9rieur. Les tuyaux correctement sp\u00e9cifi\u00e9s peuvent supporter des pressions allant jusqu'\u00e0 6 000 psi.<\/p>\n\n\n\n

Lorsque nous apprenons les bases des hautes pressions dans les tuyaux et les bouteilles, nous sommes conscients des risques de blessures graves pour nous-m\u00eames et pour ceux qui nous entourent. En cas de d\u00e9faillance d'un tuyau, il peut en r\u00e9sulter des bruits assourdissants, des pi\u00e8ces comme projectiles ou un flux de gaz qui s'\u00e9chappe et qui est assez puissant pour arracher un \u0153il. En l'absence de dispositifs de retenue appropri\u00e9s, les tuyaux peuvent \u00eatre projet\u00e9s avec une force suffisante pour amputer un membre.<\/p>\n\n\n

La complaisance prend souvent le dessus dans la plupart des cas, car les tuyaux sont robustes et con\u00e7us pour \u00eatre manipul\u00e9s fr\u00e9quemment et soumis \u00e0 toutes sortes d'abus. Mais les risques ne diminuent jamais, seulement notre perception des risques.<\/p>\n\n\n\n

The keys to hose safety are regular inspection, competent use, and replacement according to the manufacturer\u2019s guidelines. Hose replacement is necessary with regular use and should occur more frequently with high usage or in humid areas where metals corrode easily.<\/p>\n\n\n\n

Le Guide d'\u00e9valuation des risques DAN pour les op\u00e9rateurs et les professionnels de la plong\u00e9e<\/em>qui peut \u00eatre t\u00e9l\u00e9charg\u00e9 gratuitement sur le site DAN.org<\/a><\/strong>Le rapport de la Commission europ\u00e9enne sur les risques li\u00e9s \u00e0 l'utilisation des tuyaux d'arrosage contient une s\u00e9rie de recommandations pour faire face \u00e0 ces risques. Ces informations concernent le choix des mat\u00e9riaux et la fabrication, l'installation et l'utilisation des tuyaux, ainsi que l'inspection et l'entretien.<\/p>\n\n\n\n

Voici quelques recommandations cl\u00e9s pour la s\u00e9curit\u00e9 des tuyaux d'arrosage :<\/p>\n\n\n

  • R\u00e9duire au minimum la longueur des tuyaux flexibles. La meilleure pratique consiste \u00e0 utiliser des tuyaux rigides pour r\u00e9duire la longueur des tuyaux flexibles. Les tuyaux ne doivent pas d\u00e9passer 6,5 pieds et doivent toujours \u00eatre \u00e9quip\u00e9s de dispositifs de retenue aux points d'attache des deux extr\u00e9mit\u00e9s. \u00c9loignez-les des zones occup\u00e9es et placez les longs tuyaux dans un conduit de protection ou un canal couvert.<\/li>\n\n\n\n
  • Choisissez des tuyaux dot\u00e9s de caract\u00e9ristiques anti-fouettement et de mat\u00e9riaux r\u00e9sistants \u00e0 la corrosion, adapt\u00e9s aux zones tr\u00e8s fr\u00e9quent\u00e9es, aux contacts abrasifs et aux environnements typiques de la plong\u00e9e. Leurs caract\u00e9ristiques nominales doivent largement d\u00e9passer les pressions maximales possibles g\u00e9n\u00e9r\u00e9es par l'\u00e9quipement utilis\u00e9.<\/li>\n\n\n\n
  • Un \u00e9l\u00e9ment cl\u00e9 est la mani\u00e8re dont les embouts sont fix\u00e9s au tuyau. Achetez des tuyaux aupr\u00e8s de fournisseurs r\u00e9put\u00e9s et placez l'inspection des embouts en t\u00eate de votre liste de contr\u00f4le.<\/li>\n\n\n\n
  • Regular inspection of a hose\u2019s condition and monitoring the competence of people handling hoses will provide greater safety assurance.<\/li>\n\n\n\n
  • It is difficult to provide an absolute requirement, but good practice is to either inspect and hydrostatically test all gas hoses or replace them every five years, depending on the manufacturer\u2019s instructions. \u2022 Taking these steps will help you lower the risk of a serious accident. Hoses are usually designed for extreme use and are unlikely to fail if handled carefully, regularly monitored for condition, and replaced when they show warning signs of damage due to wear, corrosion, or excessively rough handling.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"
