• Any behavior creating direct or potential safety hazards.

5.2 Hand and Power Tools

• Use only after completing basic tool safety training and approval.
• Personal Protective Equipment (PPE): goggles required; dust and hearing protection for grinding/polishing; anti-cut gloves for cutting; no gloves when operating rotating machinery.
• Dust/particles: conduct dusty operations outdoors when possible; indoors must use dedicated dust collection or wet methods.
• Clear workspace before operation. Only workpieces, fixtures, and safety devices may remain.
• Confirm all safety devices (guards, shields, light curtains) are installed and functioning.
• Workpieces must be clamped securely; body kept away from cutting, rotating, heating zones.
• Verify that the rotational speed of the tool matches the rated specifications of its attachments.
• Hands or any part of the body must never be placed near blades, drill bits, pinch points, or other moving/cutting components.
• Compressed air: use pressure-limited safety nozzles only; never spray on human body; depressurize after use.
• Stop immediately if tool jams, slips, or makes abnormal sounds/vibrations.
• Unauthorized operation, modification, or disassembly of equipment is strictly prohibited.
• Storage: Sheathe all blades, power off equipment, organize cables, and return items to their designated locations with locks secured.
• Workstations must be cleaned after use; tools returned to designated location.
• All injuries or abnormalities must be reported immediately.

5.3 3D Printers

• Due to limited equipment availability and high demand, strict compliance with relevant rules is required to ensure equitable access for all users.
• Violations may result in immediate loss of 3D printer access. More information refer to Violation and Penalty Regulation.
• Unauthorized materials prohibited. New materials must be pre-approved by administrators.
• Refer to Innovation Lab 3D Printer Regulations.

5.4 Consumables

• Consumables must be taken only as needed; stockpiling and waste are prohibited.
• High-value/rare consumables require administrator approval.
• Usage must be recorded. Leftover consumables must be returned or logged. Chemicals and resins recorded in chemical ledger.
• Storage must follow labeling and compatibility; expired/contaminated consumables must not be used.
• Disposal must follow EHS and university hazardous waste protocols.

5.5 Computers and Workstations

• No unauthorized relocation, opening, or modification of computers or peripherals.
• Unauthorized software installation is prohibited. Piracy, cracking, and P2P activities are strictly forbidden. Software installation and updates are managed solely by administrators. All licensing and data compliance regulations must be strictly followed.
• Requests for new software must go through administrators.
• Users must log out of NetID accounts after use. Public machines will auto-reset; local data will be deleted.
• Storing restricted or sensitive data (personal, exam, research) is prohibited unless cleared through compliance processes.

• Hotspot creation, private servers, or policy changes prohibited.
• Users must log out when finished; power-saving practices required.

5.6 Smart Hardware Devices

• Login accounts must use applicant’s NetID; data must be cleared before return.
• Rooting/jailbreaking prohibited; cloud/network synchronization requires approval.
• Personal data collection requires prior consent. Local data must be deleted before return; proof of clearance may be required.
• Devices must be restored to default settings prior to return. All accessories (e.g., headsets, controllers, tripods, lens caps) must be included.
