- Safety is the top priority in this shop. No tool or job is more important than you.
- WEAR PROPER EYE PROTECTION AT ALL TIMES. Safety glasses with side shields are the minimum requirement. Goggles or face shields are to be used when grinding. Properly tinted goggles or face shields are to be used when welding. DO NOT WEAR CONTACT LENSES WHEN WELDING. Lenses can become fused to the cornea of the eye, which may cause blindness.
- Wear proper clothing when you come to work in the shop. Wear socks and shoes that enclose the feet and long pants to protect your feet and legs from hot sparks and sharp metal chips. Wear long sleeve shirts buttoned high to the neck when welding to protect you from sparks and welding arc light which is actinic light (excessive ultraviolet) and will cause severe burns to the skin. Rolls sleeves up or wear short sleeve shirts, remove rings, watches, and necklaces, put long hair up under a hat, and do not wear loose or dangly clothing when working around moving machine parts. Shirts must cover up to the neck to protect you from hot metal chips. Highly flammable clothing is to be avoided.
- Keep your work area clean and clear of clutter.
- Understand the operation of the machine and the procedure to be performed. DO NOT HESITATE TO ASK QUESTIONS.
- All machine guards and safety devices must be installed and in good operating condition before starting or using any machine or tool. If you are not sure, STOP and ASK the instructor.
- Use the proper tool for the job. Keep the tools sharp. Keep tool over hang as short as possible and use proper speeds and feeds so as to prevent tool breakage and chatter.
- IF AN EMERGENCY HAPPENS, THROW OFF THE ELECTRICAL SWITCH.
- Carefully plan and check each job before starting to work. Give your full attention to the job. Understand the relative motions of the various parts of the machine, the tool, and the work in order to prevent collisions.
- NEVER leave a machine unattended while it is running. Do not lean on the machine.
- Always have adequate light for the job.
- ALWAYS REPORT ANY INJURY!!!
- ALWAYS STOP THE MACHINE BEFORE taking measurements, adjusting, repairing, cleaning, or oiling.
- NEVER USE YOUR FINGERS TO REMOVE METAL CHIPS. Chips are sharp. Use a brush. Do not use air pressure. Airborne chips are eye hazards and air pressure can force chips under the machine slides causing premature wear to the machine.
- Report or correct any hazards you find in the shop. Report any malfunctioning equipment.
- Before touching metals check for heat. Metal working processes generate heat. Beware of sharp edges. Carry materials safely so as to not injure other people.
- Get help when lifting heavy or awkward objects.
- If you need help or are unsure of yourself get help from the instructor.
- Cutting tools must NOT be in contact with the work piece when starting the machine.
- Keep hands away from the starting switch or clutch lever when taking measurements, adjusting the work, or changing cutting tools. Be sure no one else is near them.
- REMOVE CHUCK KEYS AND WRENCHES FROM MOVING MACHINE PARTS. DO NOT LET GO OF THEM UNTIL THEY ARE STOWED IN THEIR PROPER PLACE. They will become dangerous projectiles if left on the moving machine part. Secure the work and the tools properly to the machine.
- On Bench grinders, the tool rest and top guard must be adjusted to within 1/8 inch (3mm) of the grinding wheel. When grinding, the tool rest is used to support your hand. This gives you better control of the operation. Only grind ferrous metals on an aluminum oxide wheel. Other materials will load up the wheel creating heat causing the wheel to burst. For the other materials use silicone carbide wheels.
The physics department is well equipped for both research and instruction, with such
- Two superconducting magnets, the smaller one operating at a field up to 6
teslaand the other reaching 13.5 tesla, are used in research on the quantum Hall effect, superconductivity, and resonant tunnelingstudies.
- A helium leak detector and a computer-based data acquisition system are available for cryogenic work.
- A mobile pumping station capable of achieving
vacuumin the range of 10 -8 torrcan be used for gas transfer and sample preparation work.
- A Class 1000 clean room for processing semiconductors and for other applications requiring a controlled environment. The clean room contains a Karl Suss photolithographic mask aligner that is able to pattern microscale circuits and devices.
- Two intrinsic-germanium detectors and a multiparameter analyzer are used in studies of coincident gamma rays. Apparatus is available for studies of the Mossbauer effect.
- Other supporting equipment includes a high-vacuum
evaporator,and a rapid thermal annealer. Additionally, the department has recently setupa phonon imaging laboratory which allows the study of heat propagation in solids. This is a low temperatureimaging system utilizing a cavity dumped argon-ion laser to excite thermal waves in semiconductors and insulators.
