Agenda • Research & Teaching Synergy (Whole greater than sum of parts) • Involves chemicals, infectious agents, animals, plants, people, radioactive hazards, machines, lasers, etc… • and People • Labs are different… • Hazard Communication & Laboratory Standard • Employees vs. volunteers & students • Field Work & Safety • Teaching • Research • ISEM – core functions • Five Steps
Synergy Research & Teaching
Synergy – Research & Teaching • 90 % communication • Why do students go to college? • What motivates graduate students? • Why are Faculty here? • What motivates faculty & staff? • 10 % information • Ah the hazards: • Health & physicals hazards • Chemical, Physical, Biological, Radioactive…
University Mission • Teaching • Research • Public Service • Research, Grants & Publications • Teaching • Public Service

Community Metrics The normally the most hazardous activity • Throughout US and several foreign countries • Thousands of trips UC-wide • Unknown number field trips annually(at least > 200 at UCR alone) Fieldwork
Specialization • Programs Craig Maxwell Laboratory Safety Inspections Chemical & Laboratory Safety Laboratory & Research Safety Radiation Safety Brenda Wong Laboratory Design Safety Biological Safety Agricultural, Field, Marine Safety
Specialized areaChemical & Laboratory Safety • Chemical Hygiene Plan • Exposure Assessment • Standard Operating Procedures • Nanomaterial safety • High hazard materials safety • Laboratory ergonomics • Departmental Contacts • Campus Policymakers • Chemical safety & fire code segregation
Synergy – hazards are just tools • Researchers select to use chemicals based upon project needs, familiarization & level of effort required • Chemical Hazard Types • Health & physical hazards (OSHA) • Laboratory Standard only applies to health hazards • Chemicals, biohazards, radioactives • Obvious overlap exists
Health Hazards - Chemicals • “statistically significant evidence” that acute or chronic health effects may occur in exposed employees • carcinogens • toxic or highly toxic agents • reproductive toxins • irritants • corrosives • sensitizers • hepatotoxins • nephrotoxins • neurotoxins • hematopoietic damaging agents • anything that damages • lungs, skin, eyes or mucous membranes
Physical Hazards - Chemicals “scientifically valid evidence” it is • combustible liquid • compressed gas • explosive • flammable • organic peroxide • oxidizer • pyrophoric • unstable (reactive) • water-reactive
Chemical Hazard Classes • Corrosives • Flammables • Oxidizers • Toxins • Reactive Chemicals
Labs are Different • Cal/OSHA Lab Standard • OSHA & Cal/OSHA Lab Standard are essentially identical • www.dir.ca.gov/Title8/5191.html • EPA Academic Lab Rule • Not yet adopted by California • Flexibility afforded academic laboratories: • delay in making waste determinations, longer accumulation times, labeling simplified, encourages lab cleanouts – useful for small quantity generators • www.epa.gov/epawaste/hazard/generation/labwaste
Cal/OSHA Laboratory Standard • Occupational regulations for labs that uses chemicals is the “Laboratory Standard” • Requires: • Employer limit exposure • www.dir.ca.gov/Title8/5155table_ac1.html • Initial and periodic exposure monitoring • Written Chemical Hygiene Plan • Capable of protecting employees from health hazards • Capable of keeping exposures below the limits • Readily available to employees
Lab Standard Requires • Standard operating procedures • Criteria determine & implement controls • Fume hoods shall function properly • Employees shall be trained • Circumstances requiring prior approval • Medical consultation and examinations • Chemical Hygiene officer & Committee
Particularly Hazardous Materials • Special provisions required for: • Select carcinogens • Reproductive toxins • Highly acute toxic substances • Establishment of a designated area • Use of containment devices such as fume hoods or glove boxes • Procedures for safe removal of contaminated waste • Decontamination procedures
Issues with Compliance • Who is responsible? • Who is the ‘Employer?’ • Who is doing the work? • Who is the supervisor? Is there a “supervisor”? • Who’s going to pay? • Fines • Controls & protection (engineering through PPE) • Exposure monitoring (initial & periodic) • Written documents • Signs • Equipment
Hazard Controls • OSHA hierarchy of controls • Engineering controls • Work practices • Administrative controls • Personal protective equipment (PPE) Laboratory Safety Orientation, 2009
Engineering Controls • Local Exhaust Ventilation • Fume hoods • Snorkels • Down-drafttables • Glove boxes • Biosafety cabinets Laboratory Safety Orientation, 2009

Fume Hood Function & Failure • Function • Draw air contaminants away from operator • Sweep breathing zone with clean air • Impediments to proper operation • Do not use front 6 inches • Do not block air flow - slots Laboratory Safety Orientation, 2009
On-line Training from UCB • http://www.youtube.com/watch?v=A4AHxLnByts Laboratory Safety Orientation, 2009
Biological Safety Cabinets • BSCs are designed to provide both a clean work environment and protection for the user • BSCs use airflow to create a barrier to airborne particles, such as microorganisms • BSCs use High Efficiency Particulate Air (HEPA) filters to clean air going into the work area and out to the environment Laboratory Safety Orientation, 2009
BioSafety Cabinet (Class IIB2) http://oregonstate.edu/ehs/LVSG-BSC-type
Clean Benches(a.k.a. Tissue culture hoods) • Laminar Flow toward Contamination Source (operator) • NO operator protection • Protects sample & work • DO NOT USE for hazardous material Laboratory Safety Orientation, 2009
Work Practices • Education • Hazard recognition and control methods. • Training • Proper techniques; emergency response & drills • Supervision - good safety performance • Housekeeping • Personal hygiene Laboratory Safety Orientation, 2009
Administrative Controls • Worker exposure • Initial placement, worker rotation for some hazards. • Medical • Surveillance and immunization. • Hazard Identification • Signs - notifications, etc. Laboratory Safety Orientation, 2009
Personal Protective Equipment The Strategy of Last Resort • Respiratory Protection • Eye, Face, Hand, Foot • Protective Clothing • Hearing • Head Protection • Barrier creams Laboratory Safety Orientation, 2009
