　　熱水器使用時(shí)一是要氧氣助燃，二是要產(chǎn)生煙氣。正常情況下，煙氣中的一氧化碳含量是很少的，但是在空氣供應(yīng)不充足的狀況下，煙氣中的一氧化碳含量會(huì)大大增加。熱水器在通風(fēng)不良情況下使用時(shí)，空氣中的氧氣越來越少，一氧化碳越來越多，缺氧使人窒息，一氧化碳使人中毒。</p><p> 　　一氧化碳是一種無色、無臭、無刺激的有毒氣體，中毒后除頭痛、頭暈、惡心外，還可有耳鳴、心悸、嘔吐、四肢無力等癥狀。使用熱水器必須通風(fēng)良好，萬萬不可粗心大意。</p><p><strong>　　怎樣避免事故發(fā)生</strong></p><p> 　　為了減少和避免事故發(fā)生，使用熱水器的用戶要牢記正確使用注意事項(xiàng)，并做到以下幾點(diǎn)：</p><p> 　　經(jīng)常檢查燃?xì)夤艿?，避免管道漏氣。發(fā)現(xiàn)漏氣時(shí)應(yīng)及時(shí)關(guān)閉燃?xì)忾y，打開門窗，禁止火種;</p><p> 　　熱水器運(yùn)行時(shí)上部冒黑煙，說明熱交換器已經(jīng)嚴(yán)重堵塞或燃燒器內(nèi)有異物存在，應(yīng)立即停用并送維修;</p><p style="text-align:

　　運(yùn)行時(shí)發(fā)現(xiàn)火焰溢出外殼或下部有火苗躥出，應(yīng)暫停使用;</p><p> 　　寒冷季節(jié)熱水器應(yīng)注意防凍;</p><p> 　　對(duì)未成年人，外來親朋使用熱水器應(yīng)特別注意安全指導(dǎo)，教會(huì)正確使用，切勿大意;</p><p> 　　排煙道應(yīng)注意防止腐蝕，煙道不可堵塞;</p><p>
