Safety of Residents

Cyber Safety
- Besides the resident and the support staff, no one shall have control of the SALE system after it is configured, unless specifically authorized by the resident or support staff.
- Sensitive information such as medical data (from the Smart Pillbox), voice recordings, and camera footage shall be encrypted and private at all times, including during storage and transit.
- The Smart Mobile Device and Remote Support Station shall require authentication to access.
- Administrator or root level accounts shall not be accessible remotely.
- The connections between the Hub, the Smart Mobile Device, and the Remote Support Station shall be authenticated and encrypted.
- Logs shall be maintained of potentially hostile actions for at least 30 days.
- Software shall be automatically kept up to date, to the extent possible.
Physical Safety
- All circuitry shall be properly insulated to prevent shocks or other electrical harms to the resident.
- Wiring shall not be easily accessible to the resident.
- When the hub is on battery power, it shall be able to detect it and reduce power consumption.
- In the event of power failure, the system shall continue operating essential items for customer safety for the durations specified below.
- The Smart Lights shall have power to continuously operate for 90 minutes.
- The Smart Hub shall have power to continuously operate for 24 hours.
- The kick buttons shall be powered by a 12V line through the battery on the wheelchair at all times.
- 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.
- In the event of an internet outage, all features that do not inherently require internet access will continue to operate.
- The Smart Pillbox shall have a way to manually remove the pills in the event of a malfunction.
- 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.
- Residents shall have minimal exposure to motors to avoid motor pinching hazards.
- The Smart Light shall remain safe to touch at all times.
- 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.
- Use tools for the task they were made for.
- Ensure the work environment is clear and there is adequate space for the current task.
- Wear safety glasses when cutting, piercing, or snapping material.
- Do not wear conductive jewelry
- Do not touch energized electrical equipment with bare hands.
- When making physical alterations to a board or electrified part, disconnect the part from the power source.
- Set up 1-meter approach boundaries for electrical equipment and circuits.
Soldering Safety
- Clean the workspace before beginning to operate the equipment.
- Ensure the cleaning sponge is wet when using a heating element.
- Wear safety glasses.
- Turn on the fume fan while working.
- Do not use lead-based solder.
- Ensure that all devices are off before leaving the lab.
Mechanical Safety
- Dedicate a specific section or the lab for storing large structures.
- Wear protective equipment while using sharp objects.
Motor Safety
- Keep your work area clean when working on motors.
- If working on a motor with voltage being supplied, wear safety glasses.
- Tie up any loose hair, clothing, and jewelry before working on a motor.
- When not actively testing a motor, turn off its connection to power.
- Do not exceed the maximum voltage of a motor.
- Keep hands away from the spinning motor.
- When testing a motor with a load, remove any delicate or breakable objects away from the testing space in case the load comes loose.
- Allow a motor to stop completely before removing any load or power source.
- 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.
- If a motor becomes hot, turn off the power supply and allow the motor to cool before continuing testing.
- When not working on a motor, store it away from the public to avoid any injury or motor malfunctions.
Chips, ICs, And PCBs
- Store chips, ICs, and PCBs in non-metallic casing and in climate-controlled places.
- 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.
- Peer-check connections before powering on a microprocessor or microcomputer.
Battery
- Wear safety glasses when connecting a battery.
- Do not bring food or drinks near a battery.
- Remove all jewelry that could touch a battery.
- Always wear closed-toed shoes.
- Handle the battery with care.
- Battery should be placed on non-conductive material.
- When disconnecting a battery from the dock or the cart, disconnect the ground terminal first.
- When connecting a battery, connect the ground terminal first.
- Avoid short-circuiting a battery (connecting the terminals together) by any means.
- When a battery is not in use and in storage, place covers over the terminals to mitigate shorting the terminals.
- In case of a puncture of the battery, keep the battery acid clean-up kit in the lab.
- When connecting or disconnecting a battery to the cart or dock ensure that the kill switch in the location is turned off.
- Store a battery in a dry location at ambient temperature.
- Store in a controlled environment.
- Only team members should have access to the batteries.
- No “loose” uncovered cells or open energized packs can be left unattended anywhere.
- 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.
