TOOLS & SAFETY

TOOL SAFETY Anytime you work with tools safety must be your primary concern. A few general rules to keep in mind are: Protective glasses or goggles should be worn whenever power tools are in use; and when chiseling, sanding, scraping, or hammering overhead, especially if you wear contact lenses. Wear ear protectors when using power tools, since some operate at noise levels that damage hearing. Be careful of loose hair and clothing, so they don't get caught in tools. The proper respirator or face mask should be worn when sanding or sawing or using substances with toxic fumes. Keep blades sharp. A dull blade requires excessive force, can slip, and cause accidents.

6. Always use the appropriate tool for the job. 7. Repair or discard tools with cracks in the wooden handles, or chips in the metal parts, that could fail and cause injury. 8. Don't drill, shape, or saw anything that isn't firmly and properly secured. 9. Take care in storing oily rags, which can spontaneously combust. 10. Don't abuse your tools. 11. Keep a first aid kit on hand. 12. Don't work with tools if you are tired or in a hurry. That's when most accidents occur. 13. Read the owner's manual for all tools and know the proper use of each. 14. Keep all tools out of reach of small children. 15. Unplug all power tools when changing settings or parts.
