Fire, Evacuation First Aid
  • Report fire or accident by
  • pressing nearest fire-alarm button in case of
    fire
  • contacting a first aid helper in case of
    accident or
  • dialing 2500 in any case of emergency

Dont panic - Keep calm - Dont take any risks
4
Fire, Evacuation First Aid
Supply the following information
Where is the accident? What happened? Are persons
injured? How many? Condition of the victim(s)?
Unconsciousness? Wait for further inquiries!
  • Warn all people in your immediate vicinity.
  • Remove victim from danger zone if possible
    without risking
  • your own safety.

5
In Case of Evacuation
  • Exit the building following the escape route
    signs and proceed to the meeting point
  • outside the main entrance in the car park in
    front of Building 25 b
  • between building 32 and 33 for Building 3
    (Helgoland)
  • Dont panic.
  • Dont run on your way out.
  • Dont use the elevator danger of power
    failure.
  • Follow the instructions of the fire wardens, the
    DESY emergency response team and the fire
    brigade.
  • Dont return to the building until authorised by
    the coordinator at the meeting point.

General Laboratory Safety Rules
  • Mouth pipetting is prohibited.
  • It is not allowed to eat, drink, smoke, apply
    cosmetics or handle contact lenses in the
    laboratories.
  • Foods and drinks must never be stored in
    laboratories and cold rooms.
  • Working areas must be kept in good order.
  • The quantity of cardboard boxes and paper in the
    laboratories should be minimised.
  • Laboratories should always be cleared up to
    permit thorough cleaning.
  • It is the duty of the supervisor to ensure that
    the laboratory is in good order and that the
    workers are instructed and trained appropriately.

7
General Laboratory Safety Rules
  • Familiarise yourself with the location of

emergency showers,
eye washing equipment,
first aid kit.
8
Personal Protective Equipment
  • Closed shoes, a lab coat and safety goggles must
    be worn when handling hazardous chemicals,
    radiochemicals or pathogenic biological agents.
  • Depending on the hazard, appropriate gloves must
    be worn. Gloves must be removed before touching
    handles, switches, taps or leaving the
    laboratory.

9
General Laboratory Safety Rules
  • Glass pipettes should be replaced by plastic
    pipettes whenever possible in order to minimise
    the risk of injuries.
  • The use of sharp items (syringes, hypodermic
    needles) should be avoided whenever possible.
  • Needles must not be recapped.
  • Sharp objects must not be placed in standard
    waste bins but into multi-safe boxes.

10
Microwave Ovens in the Lab
  • Do not place microwaves at or above eye level.
  • Never heat alcoholic solutions or flammable
    liquids in a microwave oven because of the risk
    of explosion!
  • Do not heat formaldehyde or acids (e. g. acetic
    acid) in the microwave oven as harmful vapours
    would be released.
  • Do not heat agarose with ethidium bromide but
    melt the agar first, add ethidium bromide to the
    cooled down agarose.
  • Do not cover vessels with aluminium foil.
  • Use glass beads or an abrasive glass rod to
    prevent sudden uneven boiling.
  • After heating, wait for a moment before opening
    the door of the oven in order to avoid sudden
    boiling caused by vibration or temperature shock.
  • Place the vessel gently on the bench.
  • Wear safety goggles or use a face protection
    shield when opening the oven.

Rules for Handling Chemicals Safely
  • Before using any chemical inform yourself about
    the risks associated with the chemical and the
    appropriate preventative measures to take (read
    MSDS Sheets).
  • Use substitutes that are less harmful or use
    ready-prepared solutions or tablets if available.
  • Perform all work with hazardous chemicals under
    the fume hood.
  • All containers of chemicals, including waste
    containers, have to be properly labelled.
  • Highly toxic and toxic substances are to be kept
    in such a way that only qualified and instructed
    persons have access to them.
  • The condition of all chemicals stored in the lab
    should be checked at least once a year.
  • Chemicals which are no longer needed or have
    become unsuitable for use are to be disposed of.

Biological Safety
non-hazardous
Natural organisms
hazardous
non-hazardous
Genetically modified organisms
hazardous
Depending on the hazard they present all
bacteria, viruses, parasites, fungi, algae and
mosses are classified into four risk groups.
16
Classification
  • Group 1
  • Organisms and viruses presenting no risk to
    human health and/or environment if standard
    hygiene is maintained.
  • Risk group 2
  • Organisms and viruses which may cause disease to
    human health and/or environment - the risk is
    estimated to be little.
  • Risk group 3
  • Organisms and viruses which may cause disease to
    human health and/or environment - the risk is
    estimated to be moderate.
  • Risk group 4
  • Organisms and viruses which may cause disease to
    human health
  • and/or environment - the risk is estimated to be
    high.

17
Biological Safety Administration
  • Information on projects involving GMOs classified
    as S1 is collected in form Z (Available from
    Young-Hwa Song).
  • Projects involving GMOs classified as S2 have to
    be applied for with the authorities. Information
    is collected in form Z.
  • We have only one approved S2 projectStructural
    proteomics of Mycobacterium tuberculosis.
  • It is sufficient to fill out one form Z per
    project per research group.

18
Organisms in Risk Group 1
  • Organisms and viruses presenting no risk to human
    health and/or environment if standard hygiene is
    maintained.
  • E. coli K12 and B strains (all usual expression
    hosts).
  • Experimentally proven safe strains (e.g. M.
    tuberculosis BCG).
  • Genetically modified organisms that are as safe
    as the S1 host they originate from (e.g. E. coli
    expressing gene products that are non-hazardous
    and not virulence factors).
  • Yeast strains such as S. cerevisiae and P.
    pastoris.
  • Eukaryotic cell lines such as HEK293, Sf9, Sf21.
  • Baculovirus in combination with insect cell lines
    (Sf9).

19
Organisms in Risk Group 2 (at EMBL Hamburg)
  • Genetically modified organisms expressing genes
    from Mycobacterium tuberculosis since the
    principles of pathogenicity of M. tuberculosis
    hasnt been fully understood yet.
  • Genetically modified organisms (S1 host)
    expressing genes of unknown function or virulence
    factors from donor organisms of risk groups 2-4.
  • Mycobacterium smegmatis.
  • Genetically modified organisms that are as safe
    as the S2 host they originate from (e.g. Mtb
    genes expressed in M. smegmatis).

    areas.
  • Hands must be disinfected after work before
    washing.
  • The posted hygiene plan has to be followed.
  • S 2 waste has to be sealed in autoclavable bags
    inside a laminar flow hood.
  • Samples must be transported inside EMBL, outside
    S2 areas, in containers that are break-proof and
    with an additional not-contaminated outside
    container.
  • No S2 plates in the cold room!

23
Mycobacterium smegmatis Cultures
  • All cultures should be carried out in S2 lab.
  • Lysis should be carried out in a closed vessel
    to avoid producing aerosols.
  • Transport of materials only in closed vessels.
  • All liquid handling should be carried out in
    laminar flow hood.
  • Waste should be collected separately and
    inactivated.

24
Disposal of S1 and S2 Liquid Waste
All biological waste (even S1) has to be
inactivated before discarding!
  • Whenever possible, the waste has to be
    inactivated by autoclaving.
  • Cover flasks with lid or aluminium foil.
  • Do not fill the flasks more than two third.
  • Avoid using flasks larger than 2 L.
  • Liquid S1 waste from the cell cultures also has
    to be inactivated.
  • Collect media, cells and virus in 10-L plastic
    bottle containing Lysoformin (gt5).
  • Autoclave glass flasks containing media, cells
    or virus.
  • Other glassware that has been in contact with
    media, cells or virus should be disinfected with
    Virkon S (2).

25
Disposal of S1 and S2 Solid Waste
  • Collect waste (e.g. plastic products, paper
    tissues, tips, etc.) in autoclave bags.
  • Close with tape.
  • Put into the dedicated container in the media
    kitchen.
  • Disinfect all materials that have been in contact
    with cells with 2 Virkon S.
  • Remove S2 waste immediately after ending the
    work!

26
Precautions when using alcohol-based disinfectants
  • Use ethanol at a concentration of 70 .
  • Use alcoholic disinfectants only for smaller
    areas (max. 2 m2).
  • Keep away from sources of ignition.
  • Rather wipe than spray alcoholic disinfectants.
  • Allow surfaces, hands etc to dry after alcoholic
    disinfection.

27
Protection of Expectant Mothers
Chemicals to avoid strictly (also by women in
childbearing age) are lead (Pb) and derivatives
and mercury alkyl salts
Pregnant women must not handle substances that
may cause cancer (R 45) cancer by inhalation (R
49) heritable genetic damage (R 46) harm to the
unborn child (R 61) or that present a limited
evidence of carcinogenic effect (R 40) a
possible risk of irreversible effects (R 68) a
possible risk of harm to the unborn child (R 63)
28
Protection of Expectant Mothers
Nursing mothers should minimise exposure to these
chemicals and avoid all substances that may cause
harm to breastfed babies (R 64).
Expectant and nursing mothers should take special
care when handling any kind of harmful
substances, solvents and solvent containing
substances.
Good personal hygiene and following the
guidelines for safe laboratory practice is even
more important during pregnancy.
Please consult the Head of Health and Safety
Office for advice.
29
Hygiene
  • Hands have to be cleaned before leaving the
  • laboratory or touching anything such as taps,
  • handles etc.
  • After handling agents of risk group 2, hands must
    be disinfected before washing.
  • After cleaning a skin protecting cream (e. g.
    Silonda) should be applied to avoid skin dryness
    and cracking of the skin.
  • Please see the skin care plan posted.

30
Occupational Medical Examinations
  • Based on the EMBL Staff Regulations, all staff is
    requested to undergo an initial and a leaving
    medical examination. Further examinations take
    place at regular intervals.
  • The frequency of the further examinations depends
    on your workplace.
  • The occupational physician who has been
    officially appointed by EMBL to carry out the
    examinations at EMBL Hamburg is Dr. Katharina
    Bünz and her staff.
