Fire extinguishers are designed for different types of fires, and selecting the correct extinguisher for the fire class is critical for effective and safe firefighting.

🔴 1. Water Fire Extinguisher
Suitable mainly for Class A fires involving materials such as wood, paper, cardboard, cloth, and other ordinary combustibles. Never use standard water extinguishers on energized electrical equipment or flammable-liquid fires.

🟡 2. Foam Fire Extinguisher
Foam extinguishers are commonly used for Class A and suitable Class B fires. The foam forms a layer over the burning surface, helping suppress flames and reduce the release of flammable vapors.

🔵 3. Dry Powder Fire Extinguisher
Dry chemical powder extinguishers are available in different ratings and can cover Class A, B, C and electrical applications, depending on the specific agent and certification. Always check the extinguisher label.

⚫ 4. CO₂ Fire Extinguisher
Carbon dioxide extinguishers are particularly useful for electrical equipment and certain Class B fires. They leave little to no residue, making them useful around sensitive electrical equipment.

🟡 5. Wet Chemical Fire Extinguisher
Designed primarily for cooking-oil and fat fires, especially in commercial kitchens. The agent helps cool the burning oil and forms a protective layer over the surface.

🟢 6. Clean Agent Fire Extinguisher
Clean-agent extinguishers are suitable for certain electrical and sensitive electronic equipment because they are designed to suppress fire without leaving conventional powder or foam residue.

💧 7. Water Mist Fire Extinguisher
Water mist extinguishers discharge very fine droplets that absorb heat efficiently. They are commonly intended for Class A fires, with some models carrying additional ratings depending on their design and certification.

⚙️ 8. Class D Fire Extinguisher
Specially designed for combustible-metal fires, such as those involving magnesium, sodium, titanium.

1. Measure the Target Bore Roughly
* Use an outside micrometer or vernier caliper to get an approximate dimension of the bore.
* This establishes your reference baseline for selecting parts and setting up tools.
2. Select and Install the Correct Anvil
* Choose an anvil or washer extension combination from your kit that matches the target dimension.
* Thread or snap the anvil securely onto the measuring head opposite the spring-loaded contact point.
3. Calibrate / Zero the Dial Indicator
* Set an outside micrometer to the exact target size and lock the spindle.
* Place the measuring head of the bore gauge between the micrometer anvils.
* Rotate the bezel on the dial indicator until the needle points precisely to 0 at the tightest reading (inflection point).
* Alternative: Use a master ring gauge of known size to zero the indicator.
4. Insert the Gauge into the Bore
* Tilt the gauge head slightly to fit it inside the cylinder or bore.
* Straighten the handle so the self-centering guide shoes align parallel to the cylinder walls.
5. Rock the Gauge to Find the Minimum Reading
* Slowly rock the handle back and forth along the axis of the bore.
* Watch the indicator needle move; it will sweep to a point, pause, and reverse direction.
* Note the inflection point (the point of maximum needle deflection)—this represents the true diameter perpendicular to the axis.
6. Calculate the Final Dimension
* Read the deviation from zero at the inflection point:
* Needle moves clockwise (past 0): The bore is smaller than the reference size by that amount.
* Needle moves counter-clockwise (before 0): The bore is larger than the reference size by that amount.
* Add or subtract the indicator reading from your preset reference size to determine the exact bore diameter.
7. Check for Taper and Out-of-Roundness
* Out-of-Round (Ovality): Measure at the same height while rotating the measuring head 90°. Compare the two readings.
* Taper: Take measurements at three distinc
