Some things, like cleaning up and properly filing paperwork, I think, are just a professional courtesy for the techs following you. Every lab professional, regardless of what department they work in, should know that.
I think that checklists and charts do help. They not only serve as a reminder, but also enforce accountability. When I worked at ARC, I had to sign my initials so many times everyday, I felt like I had to initial a form to go to the bathroom.
I found that when someone new comes to the blood bank it helps to not only explain the rules, but explain WHY that rule is in place and some possible negative consequences that could occur if these rules are not followed.
