SAFETY HANDLING PRECAUTIONS

1. SAFETY PRECAUTIONS

Personal Protective Equipment (PPE): Always wear appropriate PPE, including safety goggles, gloves, hard hats, and steel-toed boots when handling or installing crusher parts.

Lockout/Tagout: Always isolate and lock out the crusher from its power source before beginning any maintenance or installation work.

Lifting: Use appropriate lifting tools for specific wear parts to ensure safe and efficient installation. Heavy components such as adjustment rings (8,000-10,000kg), mantles (3-4 tons for 7ft models), and eccentric assemblies require proper lifting equipment .

Training requirement: Maintenance personnel must be properly trained on the safe and correct procedures for installing spare parts on the specific Symons crusher model. Operators should understand that using OEM or quality verified parts with correct tolerances prevents equipment failure.

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 or the wound is deep.
