  • UW Physical Sciences Lab in Stoughton (costly, but high-quality and versatile)
  • COE Student Shop instrumentation specialists (inexpensive, easy to walk over and chat about ongoing work)

Heavy Machinery Operation

• Be aware of the location of others
• Inspect the machine before use to confirm proper operation

• Minimize load weight, if possible
• Forklift and crane operation
