In addition to what's been mentioned above, our Safety Officer uses the Safety Checklist (from the 2015 Safety Manual) to track the team's safe practices throughout each daily build session. At the end of each session she gives the team a rating (which is posted on the wall). The completed checklist is kept in the Safety Binder. Five happy faces in a row earns the team cookies.
Also, all of our team members are certified in First Aid, CPR and the use of AED. New members are certified each year.
