2. FIRST AID MEASURES
Eye Exposure: If dust or debris enters the eyes, flush immediately with plenty of clean water for at least 15 minutes, holding eyelids open. Seek medical attention.
Cut Injury: Apply direct pressure to stop bleeding. Clean wound with clean water. Cover with sterile dressing. Seek medical attention if bleeding is profuse.
Inhalation: If diesel exhaust or dust is inhaled, move to fresh air. If symptoms persist (coughing, difficulty breathing), seek medical attention.
3. FIRE FIGHTING MEASURES
Flammability: Excavators contain diesel fuel, hydraulic oil, and electrical systems. Use extinguishing media appropriate for class B and class C fires.
Extinguishing Media: Use dry chemical powder, carbon dioxide (CO₂), or foam for fires involving fuel, oil, or electrical components.
Fire Response: In the event of a fire, evacuate the area immediately. Call emergency services. Do not attempt to fight a fire involving fuel tanks or hydraulic systems unless trained.

Stone Crusher
A stone crusher is a heavy-duty machine designed to reduce large rocks into smaller stones, gravel, or rock dust for use in construction, road building, and other aggregate applications. These machines use mechanical force to break down stone material, typically through compression or impact. Stone crushers come in various types such as jaw crushers, cone crushers, impact crushers, and hammer crushers, each suited to specific crushing requirements. They are widely used in mining, quarrying, construction, and recycling industries to produce consistent aggregate sizes for foundations, concrete, asphalt, and more.
Tap and Die Set
A tap and die set is a collection of tools designed for threading and cutting threads on screws, bolts, and other fasteners. The set typically includes various sizes of taps and dies, which are used for creating or repairing threads on metal surfaces. Taps are used to cut internal threads, while dies are used for cutting external threads.
A 32-piece set implies that it contains 32 individual tools, which may include both taps and dies in different sizes. The sizes can vary to accommodate a range of thread specifications commonly found in mechanical and automotive applications. These sets are useful for machinists, mechanics, or anyone involved in metalworking who needs to create or repair threads in various sizes and diameters. The set may also come with a case for organization and storage, making it a convenient and versatile tool kit for threading tasks.
