+# Autonomy Lab Safety Policies & Procedures
+
+Document serves purpose of safety guidelines (both in 701 and outside)
+
+### The importance of this safety guide is to ensure:
+
+1. **NO ONE GETS HARMED** or we mitigate the risk of people getting harm
+1. There isn’t a lot of capital damage to the car or anything in the
+   surrounding area
+1. Helps prevents any easily avoidable mistakes that could be prevented
+   and set back the timeline
+
+## General
+
+### If something starts smoking:
+
+- Press estop and turn off all power immediately
+- Clear the lab asap
+- Call for help
+
+### If fire:
+
+- Fire extinguisher is on inside of car
+- Larger one in front of 701
+
+### If something in eye:
+
+- Eye wash is on either sink in 701
+- Do not rub eye
+- Call for help
+
+### If bleeding:
+
+- Call for help
+- Apply pressure to wound
+- First Aid kit near exit of 701
+- Use gauze/band aids
+- Wash hands
+- Use disinfectant
+
+### If bleeding is not stopping:
+
+- Keep applying pressure
+- Call for help
+- Go to urgent care
+
+### If someone passes out / loses consciousness:
+
+- Call 911 NO EXCEPTIONS
+
+## When Using Equipment:
+
+### MUST:
+
+- Wear goggles
+- Wear electrical gloves (if handling +48V line)
+- Place chock blocks on wheels if tires are not on dollies
+
+This includes but not limited to: mechanical maintenance, using hand
+tools, using power tools, cutting/stripping wire, soldering
+
+### When jacking car:
+
+- Announce “ALL CLEAR, JACKING FRONT” or “JACKING BACK”
+- Announce “ALL CLEAR, LOWERING” when releasing the jack
+- Wait until clear before jacking or releasing jack
+
+### When going under car:
+
+- Announce / shout out “GOING UNDER CAR” to make sure everyone near the
+  car knows not to sit inside the car or move the car
+- Do not go under car until sure no one is going to sit in car / move
+  car
+- Put up caution tape or assign someone else to watch car or stand at
+  door so people coming in know not to go into car while you are under
+  the car
+
+### When operating experimental boards / devices / new additions to car:
+
+- Check that it works on a node not plugged into car first
+- Check board is not being back-powered through battery device
+- Operate with power supply before connecting to electronics to car
+
+### When car is in 701:
+
+- Ensure car will not drive into wall (put car on dollies or use chock
+  blocks at all times)
+- Have the car face at the wall where it won’t hit the hallway or anyone
+  else in case it drives forward by itself
+- Avoid keeping the car on it’s wheels unless needed for testing
+- Even this should be avoided by using the jack stands in the lab
+
+### When using power tools / drills:
+
+- Announce/ shout out “ALL CLEAR, DRILLING” so that all in car know to
+  be clear
+- Make sure all are clear before using tool
+- Ensure item you are drilling into is clamped in some way so that it
+  doesn’t go flying or break
+- Use step bits when possible for drilling into plastic
+
+### When wiring to a battery (if battery leads are exposed):
+
+- Make sure all are clear before removing tape / no one is touching
+  other side of battery to prevent shorts
+- If anything is loose or hanging use electric tape to prevent any
+  accidental shorts
+- Use battery boots (when possible)
+- If battery shorts, STOP what you're doing, turn off all systems to
+  prevent further damage, identify problem.
+
+### When soldering:
+
+- Ensure some sort of fan/filter is on (either the ceiling air sucker or
+  the mini fan)
+- Ensure soldering iron is not left on when finished
+
+### When using Heat-Gun
+
+- Make sure ONLY pointing at items want to heat up
+- Keep others clear when heat gun is on
+- Ensure heat gun is turned off when finished
+
+### When running new steel cables for Brake-by-Cable:
+
+- Use swage tool in vice when possible
+- Clean all steel shavings when cutting cables
+- Tape/cover all sharp ends of the cable
+
+## Test Day Procedures
+
+### Test day safety officer
+
+- One person (can be volunteer) is assigned to be safety officer for day
+- This person will make sure people are following the ALL CLEAR shouts
+- Person makes sure no one is in car when people are under car
+- Person makes sure people using tools are wearing goggles
+- Will be the person to call 911 if needed
+- Will be the first person to use the fire extinguisher if needed
+- Responsible for asking people not being safe to leave the room/test
+  environment
+
+### In General
+
+- If not directly touching / testing something on car, STAY CLEAR
+- If have curiosity questions, it’s okay to ask but wait until the team
+  member who is working is finished or save questions for reflections or
+  other times
+- If afraid you might forget your question, write it down somewhere
+- Ideally, unless it’s urgent, don’t distract people using tools and
+  working on car
+- Not only is it important for team members to focus while using tools
+  to work on the car, distractions can cause mistakes which could cause
+  the car to become unsafe
+
+### When car is ARMED
+
+- Armed means any of the following: Key is in ignition, Node boards are
+  powered
+- Take extreme care not to short connections
+- If possible, turn off car / nodes before using metal tools on the
+  boards (metal snips, screw drivers, etc)
+- If anything shorts / makes smoke/ explodes, STOP what you're doing,
+  call for help, turn all systems OFF to prevent further damages,
+  identify problem before moving on
+- If working with something connected to a battery, take even more care
+  not to short components
+
+### When outside:
+
+- Yellow caution tape and orange cones for to corral/block pedestrians
+- No one in front or behind car while car is “ARMED” NO EXCEPTIONS
+- Must have fire extinguisher in car
+
+### Before commencing Test Day run through safety checklist:
+
+- Who is designated student safety officer?
+- Does the ESTOP work as intended?
+- Is the weather suitable for a test day?
+- Is there a lab technician or someone certified who agreed they’d be
+  with you during the duration of the test day?
+- Is the school grounds team aware of what section of the sidewalk will
+  be blocked for testing?
+- Make sure all members present for test day understand what system is
+  being tested when and are conscious of any dangers that maybe
+  associated with it
