Machinery and tools, whether manual or powered, are such a common part of our lives that it is difficult to remember that they may pose hazards. Most tools are manufactured with safety in mind but, tragically, serious accidents often occur when tools are not used correctly or malfunction. 

Workers must learn to recognize the hazards associated with the different types of machinery and tools and the safety precautions necessary to prevent those hazards. The following are some key safety procedures:

• Every tool was designed to do a certain job. Use it for its intended purpose.
• Keep your tools in good condition: sharp, clean, oiled, dressed, and not abused. 
• Worn tools are dangerous. For example, the teeth in a pipe wrench can slip if worn smooth, an adjustable wrench will slip if its jaws are sprung, and hammer heads can fly off loose handles. 
• Tools subject to impact (chisels, star drill, punches, etc.) tend to "mushroom". Keep them dressed (sharpened) to avoid flying spalls. Use tool holders. 
• Do not force tools beyond their capacity or use "cheaters" to increase their capacity. 
• Always wear the PPE required for the job. Protect your eyes, hands, ears, and other body parts. Keep clothing out of your work. 
• Always keep work areas clean and free of debris.  
• Keep tools off the floor to prevent tripping hazards
• Always work in well-lit areas only.
• Tools not in use must be safely stored.
• Metal slivers, wood slivers, sawdust, moisture, and grime should be removed from tools before they are stored. Never remove these particles with bare hands.
