📢 SCUBA SAFETY ALERT: CRITICAL VALVE MISMATCH !

⚠️ 潛水安全警告：致命的氣樽閥門誤配！

Divers and professionals, please take a moment to read this life-saving message. A tiny technical error can turn a scuba cylinder into a lethal "missile."

各位潛水同好及業界朋友，請花一分鐘閱讀這則救命信息。一個微小的規格錯誤，足以令氣樽變成「導彈」。

🚨 真實慘劇 / Real Tragedies:

Fatal accidents have occurred in Australia and globally. During filling, the valve ejected at high velocity, leading to fatalities or severe injuries.

澳洲及海外曾發生多宗致命事故。技術員在充氣時，氣樽閥門（Valve）突然以極高速度噴出，造成操作員當場死亡或面部重傷。

❌ 致命錯誤 / The Fatal Mistake:

Forcing a Metric M25 valve into an Imperial 3/4" NPSM cylinder (or vice versa).

將 公制 M25 (Metric) 閥門強行旋入 英制 3/4" NPSM (Imperial) 氣樽（或反之亦然）。

• 初期假象 / Initial Illusion:

The first few turns may feel loose, leading to a false sense of fit.

旋入前幾圈時可能感覺很鬆，讓人誤以為匹配。

• 強行鎖死 / Forced Wrenching:

It binds halfway due to mismatched threads; many mistakenly use a wrench to force it down.

旋到一半因規格不合而咬死，若用扳手強行鎖到底，會徹底破壞螺紋牙的完整性。

• 結構崩壞 / Structural Failure:

The threads are damaged and cannot hold the massive pressure.

此時螺紋已受損，無法承受高壓。

🔥 物理威力 / Physical Power:

At 230 bar, the valve endures 2,000-3,000 kg of upward thrust. If threads fail, the valve launches like a rocket!

在 230 bar (3300 psi) 壓力下，閥門承受約 2,000-3,000 kg 的向上推力。一旦螺紋崩裂，威力足以擊穿牆壁！

✅ 專業建議 (SOP) / Professional Advice:

1. 對照圖片檢查刻印 / Identify Stamps:

Verify cylinder neck stamps against valve specs.

充氣前必須核對氣樽頸鋼印與閥門刻印。

2. 手指旋入準則 / Finger-Tight Rule:

Correct valves should screw in easily by hand. If a wrench is needed halfway, STOP immediately! 正確規格應能用手指輕鬆旋入。若需動用扳手才能旋到底，請立即停止！

3. 信任專業 / Trust Professionals:

Never DIY install valves from unknown sources.

潛水安全，由細節做起！請分享此信息，救人一命。

切勿安裝來源不明或自行網購錯誤的閥門。

⚠️ IMPORTANT: For Owners of Second-hand SCUBA Cylinders
Whether you bought it used, received it from a friend, or have cylinders stored at home, there is a potential "silent risk." A mismatched valve may seem fine under low pressure but can become a lethal projectile during filling or temperature changes.
If you have any doubts about your equipment, STOP using it immediately. Contact Infinity Dive for a professional inspection. Your safety—and the safety of your family and dive buddies—is our priority.
⚠️ 特別提醒：私人擁有及二手水肺氣瓶之安全建議
針對自備氣瓶、購入二手器材或於家中存放水肺氣瓶的人士，請務必提高警覺。
閥門規格誤配（Mismatch）的風險往往極為隱蔽，在日常儲存時未必有明顯異樣，但在高壓充氣過程或環境氣溫劇烈變化時，壓力可能導致閥門瞬間脫落並產生強大衝擊力，造成致命危險。
若閣下對現有裝備的規格配對有任何疑慮，請立即停止使用，並聯繫 Infinity Dive 進行專業鑑定。我們致力於為悉尼潛水界提供專業的安全評估，確保閣下、家人及潛伴的生命安全。
