Handling Hand and Power Tools
Hand tools are tools that are powered manually. Their greatest hazards result from misuse and improper maintenance. When handling hand tools, always observe the following precautions:
1. Always use the proper tool for the job. Use the right type and size tool for each application.
2. When carrying tools, always keep the cutting edge down.
3. Keep hands clean when using tools. Avoid grease, dirt, or oil on hands when using any tool.
4. Clamp small pieces when using a hacksaw, screwdriver, or soldering iron.
5. Avoid using chisels and punches with mush- roomed heads. Pieces of metal can break off, causing injuries.
6. Never use a file without a handle.
7. Never use plastic-handled tools near an open flame.
8. Keep metal tools clear of electrical circuits.
9. When cutting wire, always cut one wire at a time to avoid damaging the cutting tool.
Power tools used in electronics are normally powered with electricity. When handling the power tools, always observe the following precautions:
1. Ensure all power tools have grounded three-prong plugs or an insulated housing approved by UL (Underwriters Laboratories).
2. Make all adjustments to the machine before turning it on.
3. Double-check any special setups before applying power.
4. Keep all safety guards in proper position at all times.
5. Clean the work area before using a power tool and keep it clean.
6. Keep power tools clean, and put away them when they are not in use.
7. Avoid treating power tools roughly, dropping them, or hitting them against things.
8. Keep all power tools in good condition with regular maintenance.
9. When finished using a power tool in the workshop, find a safe place to set it down when working.
