It sounds like you’re asking about an old fire extinguisher device, but I’ll need a bit more detail (or a photo) to identify the exact type.
In general, old fire extinguishers can fall into a few common categories:
🔥 1. Soda-acid extinguisher (very old type)
- Metal cylinder, often heavy
- Used water + acid reaction to produce pressure
- Common in early–mid 1900s
- No longer used today
🧯 2. Carbon tetrachloride extinguisher
- Glass or metal container
- Used a toxic chemical to smother fire
- ⚠️ Now banned in many countries due to health risks
🧯 3. Pump or hand-pressurized water extinguisher
- Simple tank with hand pump on top
- Filled with water only
- Used in homes, farms, and old buildings
🧯 4. CO₂ or early gas extinguisher
- Metal cylinder, sometimes with a horn nozzle
- Released gas to cut oxygen supply
- Still used today in updated form
🧠 How to identify yours quickly
Check:
- Shape (round tank, bottle-like, or boxy)
- Material (copper, steel, brass, glass?)
- Any labels or writing
- Nozzle type (pump, horn, lever, or valve)
⚠️ Important safety note
Old extinguishers may:
- Be pressurized and dangerous to open
- Contain toxic or expired chemicals
- Leak or corrode over time
👉 Don’t try to open or test it unless handled by a professional.
✔️ Bottom line
It’s likely an older mechanical or chemical fire extinguisher, possibly from early safety equipment designs before modern ABC dry-chemical types.
If you can upload a picture or describe it (color, size, material), I can tell you exactly what model/type it is 👍
