Physical Safety

  1. All circuitry shall be properly insulated to prevent shocks or other electrical harms to the resident.
    1. Wiring shall not be easily accessible to the resident.
  2. When the hub is on battery power, it shall be able to detect it and reduce power consumption.
  3. In the event of power failure, the system shall continue operating essential items for customer safety for the durations specified below.
    1. The Smart Lights shall have power to continuously operate for 90 minutes.
    2. The Smart Hub shall have power to continuously operate for 24 hours.
    3. The kick buttons shall be powered by a 12V line through the battery on the wheelchair at all times.
  4. In the event of a power failure, devices that have backup battery power shall have a stable and safe transition from drawing power from the outlet to the battery.
  5. In the event of an internet outage, all features that do not inherently require internet access will continue to operate.
  6. The Smart Pillbox shall have a way to manually remove the pills in the event of a malfunction.
  7. The Smart Door Lock must be able to be unlocked from the outside without being damaged in all circumstances. This includes a simultaneous power failure, battery depletion, internet outage, and unresponsive resident.
  8. Residents shall have minimal exposure to motors to avoid motor pinching hazards.
  9. The Smart Light shall remain safe to touch at all times.
  10. The Smart Hub shall have a case that prevents accidental contact with the fan

Lab Safety

General Safety Concerns

While building the mechanical components of the SALE system, the team will wear closed-toed shoes, safety glasses, and no loose accessories. The team will also adhere to all laboratory safety rules set forth by Lafayette College.

 

  1.  Use tools for the task they were made for.
  2. Ensure the work environment is clear and there is adequate space for the current task.
  3. Wear safety glasses when cutting, piercing, or snapping material.
  4. Do not wear conductive jewelry
  5. Do not touch energized electrical equipment with bare hands.
  6. When making physical alterations to a board or electrified part, disconnect the part from the power source. 
  7. Set up 1-meter approach boundaries for electrical equipment and circuits.

 

Soldering Safety

  1. Clean the workspace before beginning to operate the equipment.
  2. Ensure the cleaning sponge is wet when using a heating element.
  3. Wear safety glasses.
  4. Turn on the fume fan while working.
  5. Do not use lead-based solder.
  6. Ensure that all devices are off before leaving the lab.

Mechanical Safety

  1. Dedicate a specific section or the lab for storing large structures. 
  2. Wear protective equipment while using sharp objects.

Motor Safety

  1. Keep your work area clean when working on motors.
  2. If working on a motor with voltage being supplied, wear safety glasses.
  3. Tie up any loose hair, clothing, and jewelry before working on a motor.
  4. When not actively testing a motor, turn off its connection to power.
  5. Do not exceed the maximum voltage of a motor.
  6. Keep hands away from the spinning motor.
  7. When testing a motor with a load, remove any delicate or breakable objects away from the testing space in case the load comes loose.
  8. Allow a motor to stop completely before removing any load or power source.
  9. If a wire becomes exposed for any reason or a motor malfunctions, turn off all power being supplied to a motor and allow it to cool down before fixing any issues.
  10. If a motor becomes hot, turn off the power supply and allow the motor to cool before continuing testing.
  11. When not working on a motor, store it away from the public to avoid any injury or motor malfunctions.

 

Chips, ICs, And PCBs

  1. Store chips, ICs, and PCBs in non-metallic casing and in climate-controlled places.
  2. If a chip, IC, or PCB has been run for an extended period of time, allow at least two minutes for parts to cool before handling.
  3. Peer-check connections before powering on a microprocessor or microcomputer.

 

Battery

  1. Wear safety glasses when connecting a battery.
  2. Do not bring food or drinks near a battery.
  3. Remove all jewelry that could touch a battery. 
  4. Always wear closed-toed shoes.
  5. Handle the battery with care.
  6. Battery should be placed on non-conductive material. 
  7. When disconnecting a battery from the dock or the cart, disconnect the ground terminal first.
  8. When connecting a battery, connect the ground terminal first.
  9. Avoid short-circuiting a battery (connecting the terminals together) by any means.
  10. When a battery is not in use and in storage, place covers over the terminals to mitigate shorting the terminals.
  11. In case of a puncture of the battery, keep the battery acid clean-up kit in the lab.
  12. When connecting or disconnecting a battery to the cart or dock ensure that the kill switch in the location is turned off.
  13. Store a battery in a dry location at ambient temperature.
  14. Store in a controlled environment.
  15. Only team members should have access to the batteries.
  16. No “loose” uncovered cells or open energized packs can be left unattended anywhere.
  17. All work on open cells and packs must occur within the safety zone, and a safety watch person must continuously observe from outside the safety zone.
