Lab Standard
• US Code, Title 29 CFR 1910.1450
• Occupational Exposures to Hazardous Chemicals in Laboratories
• Enforced by OSHA
• In Minnesota, by Inspectors from the Dept. of Labor and Industry (MNOSHA)
• Location & operation of emergency response equipment
Operation of Fume Hoods
• Magnehelic gauges and how to check if hood is operating properly,
• Use of vertical and horizontal hood sashes & locks,
• Work 8” to 10” inside hood to contain airborne contaminants,
• Do not block exhaust vents or clutter inside of hood with excess stored chemicals.
Chemical Storage Plan
• Flammable storage cabinets
• Other designated flammable and combustible liquid storage
• Acid storage
• Oxidizer storage
• Chemical waste storage
• Radio-isotope stock and waste storage
Chemical Container Labeling• Original container labels should not be defaced,• Required label information:
– Complete name of chemical s(no abbreviations)– Date of preparation– Initials of preparer– Hazard warnings, Assume dilutions have same
hazards as concentrated material.
Personal Protective Equipment
• Laboratory coats or aprons
• Chemical resistant gloves
• Chemical splash goggles & face shields
• Disposable face masks & respirators
• Ear plugs or muffs for noisy environment
Emergency Use Equipment
• Fire Extinguisher
• Eye Wash/Deluge Shower
• First Aid Supplies
• Chemical Spill Cleanup Supplies
• Emergency Call List
Emergency Procedures
• Fire or fire alarm
• Chemical spill
• Biological or radiological spill
• Chemical exposure incident
• Personal Injury
Fire or Fire Alarm
Fire Alarm
• Leave building immediately via nearest exit
Fire in lab– Remove/relocate anyone in danger,– Activate building fire alarm,– Confine/contain fire by shutting door,– Extinguish fire only if small and trained to use
extinguisher, otherwise evacuate.
Chemical Spill
• Leave spill area,
• Alert neighbors,
• Block off entrances to lab, prevent anyone from entering,
• Report to EHS office at 7273
• For more detailed information, consult the chemical spill response guide at www.d.umn.edu/ehso
Radioactive Material Spill
• Inform others and restrict from area, • Use GM instrument to survey self and others who
may be contaminated,• Remove all contaminated clothing,• Call EHS office at 7273• Do not attempt to clean up spill, wait for EHS
personnel,• Consult the Radiation protection page at
www.d.umn.edu/ehso/radiation for more detailed information.
Biohazard Material Spill
• Notify all other lab workers,• Restrict access to spill area,• Remove contaminated clothing, place in
autoclave bag,• Call EHS office at 7273 • Consult the Biological safety page at
www.d.umn.edu/ehso/biosafety for more detailed information.
Chemical Exposure Incident
• Immediately flush affected area with eyewash or deluge shower,
• Flush affected area for 15 minutes,• Remove clothing splashed by spill,• Relocate to fresh air and check for
breathing and pulse,• Transport to emergency services with
copy of MSDS for treating physician.
Personal Injury
• Administer first aid,• Transport to emergency services,• Call 911 for serious injuries,• Complete “Employee Incident Report”
form within 24 hours,• Supervisors must complete a “Supervisor
Incident Investigation Report” within 48 hours.
Experiment PlanningRisk Assessment
• What are the potential hazards?
• What could go wrong?
• What will you do if it does?
• How can risk be minimized?
Potential Hazards?
Chemical exposures• Acute and chronic health effects
• Exposure limits, volatility, particle size• Amounts used, how handled• Process flow
• Skin and eye contact hazard• Corrosive/caustic, pH, water reactive• Absorbs through skin
• If an item is knocked over or there seems to be a problem with materials or equipment (noise, smell, heat, odd odor, etc) report it to your supervisor, Lab Safety Officer, or the EHS office. Use 911 as necessary.
Avoidance of Routine Exposures
• Develop safe habits,• Avoid unnecessary exposure to chemicals by
any route,• Do not smell or taste chemicals,• Inspect gloves and make sure they are correct
polymer for the chemical being used,• Eliminate or minimize release of toxic
substances into air.
Working Alone
• Avoid working alone in labs when using hazardous chemicals or processes,
• Use a buddy system or,
• Notify someone in the facility if you must work alone.
Hazardous Waste
• Follow procedures the Hazardous Waste Management website,
• Label all containers appropriately, use start/end dates,
