War Stories, Undergraduate TAs, and Hands On Training
Evolution of Laboratory Safety and TA Training
History of NAU Chemistry Safety and TA Training at NAU – How do we differ from ASU and UofA?
Current Course Design of “Laboratory Safety and Supervision”
Weaving War Stories Into Lab Safety Training – Some Examples
Hands on Aspects of Course: Laboratory Safety Audits, and Mock Emergency Training
NAU Chemistry Department: 1981
Fall 1981 – My First Semester at NAU as 1st Lab Mgr.15-20 Tenure Track Faculty who are Listed as Lab Instructors –
TAs Never listed as Instructors.4 Staff (1.5 Office, 1 Lab Mgr., 1 Stores, 0.5 Inst. Room)2 GTAs20-25 Undergraduate TAs and Stockroom Employees20-30 Total Sections for all Lab Courses per SemesterVery Limited State Operations and Student Wages Budgets that
never really increased much in 15 yearsRisk Management Lab Safety – One Person in FacilitiesNearly Everything in Chemistry Building
NAU Chemistry Department: 2014
Fall 2014 – Now 3 Lab Mgrs. (2 added last five years)15-20 Faculty Tenure Track, Lecturers, & 4 Lab Instructors6 Staff (2 Office, 3 Lab Mgr., 1 Stores)8-10 GTAs40-50 Undergraduate TAs and Stockroom Employees~100 Total Sections for all Lab Courses per SemesterMost of Lab Program Funded by Lab Fees Including Salary for
Undergraduate Employees not GTAs ~60-100 Chemistry Majors per YearIn three different building: CHM, Wettaw, Sci. Lab, New!EH&S 6-7 Professionals
How Have We Attempted to Make This Work?
History of our Safety & TA Training Program:Annual Saturday Morning Safety Program (lecture and fire
extinguisher training) 1-2 hour Spring Refresher on 1st Friday of Semester Incorporated Skits and Mock Emergencies into training
sessions (involved 2-4 faculty)Created course CHM599 for undergraduate employees and
graduate students.Course evolved to CHM 295 and 595, Laboratory Safety an
Supervision, approved by curriculum committee early 90s.
CHM 295 & 595 – Lab Safety and Supervision
CHM 295 and 595 is offered for 1-2 units for undergraduatesFirst unit is for safety training onlySecond unit is for TA training (All TAs in training take 2 units)Required for all students workers in labs (not research)Completion of organic chemistry is required for CHM 595CHM 595 is a required course for all graduate studentsOften taken by students in our science teacher training
programMini Course Format: first 8 weeks of semesterUse Risk Assessment Approach in Our Labs
Safety Training
Presentation format uses war stories, video tapes, group exercises, hands-on activities, EH&S training, and lecture
Evaluation based on weekly quizzes, final, audit, and completion of Mock Emergency Training (CPR xtra)
Texts used include “Safety in Academic Chemistry Laboratories” , “NAU Chemistry Department Chemical Hygiene Plan”, and a reading packet.
Objectives: Familiarity with lab safety concepts, emergency response, references, department & NAU policy and meet OSHA training requirements.
TA Training
Some Common Training Done for All TAs - ChangingUpper Division Labs 1-2 TAs Mostly Graduate Students
Trained Mainly by Faculty Instructor for LabFor General and Organic Chemistry Labs (multiple
sections) TAs are required: Shadow a Lab Section before their section or the semester before Attend All Required TA Meetings Complete a Weekly Workbook
Course Schedule
First week: EH&S Chemical Hygiene Training, Essential Lab Safety and Emergency Response
Week 2: Hazard Codes, Labels, SDS, Group ExerciseWeeks 3-5 Fire Safety, Chemical and Hazardous
Waste Management, Toxicology, Lab Procedures, Laboratory Safety Audit
Week 6: Mock Emergency TrainingWeek 7: Special Lab Hazards and ProceduresWeek 8: Safety and TA Finals
Group Formation
Groups of 4-6 students
Composition of groups is based on chemistry background and Personality
Groups work together throughout the course
Standard Lab Safety Class Format
Hand back and go over quiz from previous week Nearly Every quiz with have Emergency Response and
Prevention question applying war story.Short Lecture over topic(s)Group work applying to lecture focusVideo, tour to see safety stuff or more lectureQuiz
Example War Stories and Lessons
My Stupid Run In With Sulfuric Acid and Lessons Learned
Sodium Amide IncidentNitric Acid and Ethanol Explosion and Hazardous
Waste CollectionMethyl Methacrylate Explosion and Chemical StorageBreaking 2.5L Bottles of Conc. HCl and Transporting
ChemicalsRecent – Nitrile Glove Incident(s)
Laboratory Safety Audit
Each student conducts audit
If possible students check areas where they work
Chemical inventory is done as part of audit
10% of student’s grade is base on audit
Resulting audit and inventory very useful
Mock Emergency Training
Mock emergencies are setup and run by past students in the course, faculty and staff, risk management staff, and campus security
Student groups rotate through 4-6 emergency scenarios over 2-3 hour period.
Each scenario is as real as possible to allow students to practice their emergency response skills
Scenarios also allow for participants to review causes and prevention of lab emergencies
Schedule for Each Scenario
Organize in lecture roomWalk to sceneAssess scene (5-10 sec.): safe to help, scope of problemInitial Response (30 seconds): evacuate lab, put out
fire, notify security, evacuate building, CPR, first aidManage Scene (up to 5 minutes): witnesses, EMS,
MSDS, scene control, TLCScenario ends and group look for causes and preventionCritic by victims and observers, do participant notesReturn to lecture room
Class Responding Groups Students, Faculty and Staff
Team leaderPerson to notify campus
security (EMS)Observer – fills out “Record
of Safety Incidence”Other group membersEach group member must
rotate through each of the roles above
Victims – folks simulating injuries or conditions of some sort.
Bystanders – folks who scream or just confuse the scene.
Observers – people not part of the scene who evaluate the response of each group
Participant Roles for Mock Emergency Training

Mock Emergency Training Objectives
Provide hands-on experience for class membersFun review of safety for student employees who have
taken the courseProvide safety training for faculty and staffHeighten general safety awareness in departmentFoster cooperation between our department, risk
management, and campus security Buy in and focus on lab safety (video example)
