Hallo,

es wäre sehr nett und hilfreich, wenn jemand Zeit finden würde meinen Vortrag über „brennbare Flüssigkeiten“ im Labor zu korrigieren, ich will mich nicht unnötig blamieren (und die Leute hier sind alle im Stress um da mal drüber zu fliegen).

Besten Dank im Voraus!

Grüsse,
Nicole

P.S. Ich hoffe es ist nicht schlimm, dass ich keine Hervorhebungen gemacht habe im folgd. Text.

PPS. Wie übersetzt man dies: „Materialien, die bei 35°C weder fest noch salbenförmig sind, und bei 50°C einen Dampfdruck von 3 bar oder weniger haben“ ? Danke!

about flammable liquids

definition:

Flammable liquids are materials with a flashpoint.
They belong to one of the hazard categories called „Verordnung über brennbare Flüssigkeiten“, briefly „VbF“.

VbF, hazard categories

hazard category type A:

  • liquids having having a flashpoint described in classes AI till AIII that do not dissolve
    in water, or whose flammable constituents disolve in water

AI : liquids with flashpoint below 21°C
AII: liquids with flashpoint from 21°C till 55°C
AIII: liquids with flashpoint over 55°C till 100°C

hazard category type B:

  • liquids having a flashpoint below 21°C that dissolve in water or whose flammable constituents disolve in water

note generally:
A liquid with a lower flashpoint is more dangerous than a liquid with a higher flashpoint!

rules about flammable liquids handling

  • it is not allowed to store more than 1 L of flammable liquids whose belong to those hazard classes: AI (e.g. Toluene), AII (e.g. Xylene), B (e.g. Acetone) in the laboratory (=working place)

  • keep in mind to transport small amounts of flammable and dangerous liquids from the chemestry storage to your laboratory

  • always combine the bottle/vessel which you are transporting with an additionally vessel, fragile bottles as well as non-fragile bottles

  • while transporting don’t walk to fast, go careful around corners, open doors carefully, too, if you weare long white coat pay attention to don’t shut it into closing doors

  • just store a limit of most used liquids in the laboratory

  • it is allowed to store flammable liquids up to 5 L in fragile vessels,
    up to 10 L is has to be stored in a non-fragile vessels and in a save place

  • do not store flammable liquids in foodstuff vessels (eg. can, water bottle)

  • don’t pipet flammable solvents with your mouth

  • while handling with solvents wear disposable gloves, and don’t clean your hands or body parts with solvents

  • ideal storage place: special cupboard with catchment tray and suction plant, or rooms built after DIN 12925 Part 1

  • work in an extractor hood, if necessary wear breathing protection, when you decant solvents

  • avoid spark formation and unshielded flames or fire !!

  • vessels with more than 5 L volume have to be electrostatically conductive, when decanting you must ground the vessel to avoid flash

  • dispose used moist materials separately (extra trash can in your laboratory, or ask Ms. Swatek)

  • rinse, or evaporate empty vessels of solvents, there is an explosion risk, if the heat or spark formation in the surrounding is high enough

  • keep always in mind: don’t be careless ! eg. when you refill small wash bottles in the laboratory, use the extractor hood for protection; look out for any kind of spark formation sources, or unshielded flames (simple power socket, or unisulated cabels could be a source of danger)

  • avoid as possible to extinguish with water altough the solvent belongs to the hazard category „B“ (solvable with water), try to use the fire extinguisher instead of water, fire extinguisher can be found on the floor, or in the laboraty

most used solvents in our laboratories

  • acetone (ketone) - VbF B , extinguish with powder, foam
    highly flammable (F), irritant (Xi)
    slightly polluting substance

  • ethyl alcohol - VbF B, extinguish with CO2, powder, foam
    highly flammable (F)
    slightly polluting substance

  • isopropyl alcohol - VbF B, extinguish with powder, foam
    highly flammable (F), irritant (Xi)
    slightly polluting substance

  • toluene (benzene) - VbF AI - extinguish with powder, foam
    highly flammable (F), harmful (Xn)
    polluting substance

  • xylene (dimethylbenzene) - VbF AII - extinguish with CO2, powder, foam
    flammable, harmful (Xn), irritant (Xi)
    polluting substance

At least can be sayed that we must take care and act upon the rules you heard to avoid possible accidents at all cost.

Danke erst mal!! (etwas Text)

hazard category type A:

  • liquids having having a flashpoint described in classes AI
    till AIII that do not dissolve
    in water, or whose flammable constituents

(DO NOT???)

disolve in water

Ja, „do not“, denn diese Gruppe löst sich nicht in Wasser; ist es richtig ausgedrückt?

halllo Nicole,

vorher ging’s etwas schnell, deswegen muß ich mich auch stellenweise selbst korrigieren

  • always

STORE ???

the bottle/vessel which you are transporting

IN ANOTHER

vessel, fragile bottles as well as
non-fragile bottles

  • while transporting don’t walk to fast, go

carefulLY

around
corners, open doors carefully, too, if you

WEAR LONG CHEMIST’S ROBES PAY ATTENTION NOT TO SHUT THEM IN
CLOSING DOORS

  • it is allowed to store flammable liquids up to 5 L in
    fragile vessels,
    up to 10 L is has to be stored in a non-fragile vessels and in
    a save place

UPTO 5L FLAMMABLE LIQUITS ARE ALLOWED TO BE STORED IN FRAGILE
VESSELS
UPTO 10L THE VESSELS HAVE TO BE NON-FRAGILE

So, daß war mal die Korrektur der Korrektur.

hallo Nicole,

hier kommt der 2. Teil

  • rinse, or evaporate empty vessels of solvents,

ATTENTION: HEAT OR SPARK FORMATION NEARBY MAY CAUSE THE SOLVENT
TO EXPLODE
TO AVOID DANGER REMOVE ALL POSSIBLE SCOURCES SUCH AS SIMPLE POWER SOCKETS,UNISULATED CABLES AND OTHERS
WHEN REFILLING EVEN SMALL WASH BOTTLES USE THE EXTRACTOR HOOD

there is an
explosion risk, if the heat or spark formation in the
surrounding is high enough

  • keep always in mind: don’t be careless ! eg. when you refill
    small wash bottles in the laboratory, use the extractor hood
    for protection; look out for any kind of spark formation
    sources, or unshielded flames (simple power socket, or
    unisulated cabels could be a source of danger)

TO EXTINGUISH BRUNING SOLVENT USE THE FIRE EXTINGUISHER FOUND ON THE FLOOR OR IN THE LABRATORY. DON’T USE WATER (NOT EVEN FOR SOLVENTS THAT BELONG TO THE CATEGORY B).

  • avoid as possible to extinguish with water altough the
    solvent belongs to the hazard category „B“ (solvable with
    water), try to use the fire extinguisher instead of water,
    fire extinguisher can be found on the floor, or in the
    laboraty

HOW TO EXTINGUISH SOME OF THE MOST USED SOLVENTS IN OUR LABORATORY:

most used solvents in our laboratories

TO AVOID ACCIDENTS EVERYBODY HAS TO ACT ACCORDING TO THE RULES EXPLAINED ABOVE

At least can be sayed that we must take care and act upon the
rules you heard to avoid possible accidents at all cost.

So, ich hoffe, ich hab das noch rechtzeitig geposted.
(für 100% Fehlerfreiheit kann ich allerdings auch nicht garantieren)

PPS
Hallo Nicole,

PPS. Wie übersetzt man dies: „Materialien, die bei 35°C weder
fest noch salbenförmig sind, und bei 50°C einen Dampfdruck von
3 bar oder weniger haben“ ? Danke!

Was soll „salbenförmig“ sein? Ansonsten:

Material that are neither solid nor [salbenförmig] at 35 °C, and that have a vapo(u)r pressure of 3 bar or less at 50 °C.

Vapor ist US, vapour UK-Englisch.

salbenförmig
Hallo Kubi,

auch Dir erstmal Dankeschön!

„salbenförmig“ das stammt aus dieser (hieb und stichfesten) Definition, hätte man nicht „deutscher“ ausdrücken können.
Das sind die Stoffe, die nicht fest, aber „medium“-fest sind, na ja, matschige Pampen.
Ich werde das weglassen, schon der normale Satz klingt nach „da rein da raus“.

Grüsse,
Nicole *fest*

Hallo, Nicole,
der Fachausdruck dafür dürfte im Deutschen „pastös“ sein.
Das führt dann zu „paste-like“

nochmal: salbenförmig
Hallo Eckard (und alle Dudenkenner?),

damit ihr nicht denkt, ich denke mir den Begriff „salbenförmig“ nur aus, hier das Wort schwarz auf weiss:

Hallo,

es wäre sehr nett und hilfreich, wenn jemand Zeit finden würde
meinen Vortrag über „brennbare Flüssigkeiten“ im Labor zu
korrigieren, ich will mich nicht unnötig blamieren (und die
Leute hier sind alle im Stress um da mal drüber zu fliegen).

Besten Dank im Voraus!

Grüsse,
Nicole

P.S. Ich hoffe es ist nicht schlimm, dass ich keine
Hervorhebungen gemacht habe im folgd. Text.

PPS. Wie übersetzt man dies: „Materialien, die bei 35°C weder
fest noch salbenförmig sind, und bei 50°C einen Dampfdruck von
3 bar oder weniger haben“ ? Danke!

Material which at 35 degrees centigrade is neither solid nor has the consistency of a salve and which have a whatever the hell dampfdruck in english is at a barometric pressure reading of three or less.

Note: material can be in the plural but in this sentence would more likely be singular. Other examples are homework. (I have a lot of homework. Not homeworks. And that biggest of all bugaboos: information. A native speaker would never say I have some informations for you. Always information. The best way I can explain it is that a native speaker sees these items (and there must some others that escape me at the moment) as a big cheese from which something can be cut if desired. Thus - there is a lot of information on the internet. I think I will try to find out the name of Gerhard Schroeder’s mother’s cat. That is A PIECE of information that would interest me.)

That can be used in place of which but which is a bit more formal, hence more properly used here.

possible adjustments follow (I did not read all the other answers, incidentally, so there will be some duplication.

xxx:aboutxxx CONCERNING flammable liquids

nota bene: By and large, when going from everyday language to something more formal, educated native speakers tend to switch from that portion of the English vocabulary which came from the old Anglo-Saxons, who had the honor of speaking something rather like Frisian, to that portion of the English vocabulary which comes from the French language. Please note that I am not saying from French, but rather from that portion of English which derives from French. I recommend a good history of the English people and language, should that confuse you.

definition:

Flammable liquids are materials XXXwithXXX WHICH HAVE a flashpoint.
They belong to one of the categories OF HAZARDS referred to in the REGULATIONS „Verordnung
über brennbare Flüssigkeiten“, briefly „VbF“.

note the switch to a French grammar form. hazard categories sounds a bit as if the categories are themselves hazardous.

VbF, hazard categories

hazard category type A:

  • liquids having xxxhavingxxx a flashpoint described in classes AI
    till AIII

better: Al to Alll
or: Al to and including Alll
or: Al through Alll

till is probably usually used only with time, although this is off the top of my head: I am staying until two o’clock. Then I must go.

which are those which (beware here, are we talking about things ALL OF WHICH belong in Al through Alll and also do not dissolve in water, or some do and some do not dissolve in water?. Put another way, are we speaking of one circle with both A and B in it, or a circle A and a circle B which overlap in part. I suspect the former, but I cannot tell from the english sentence. I bet you can’t tell from the German one, either, judging by the translation. Normally not a big deal, but to avoid some dunderhead misunderstanding and blowing himself up, we should probably err on the side of caution and subsequent verbosity. up do not dissolven water, or whose flammable constituents xxxdisolvexxx ARE WATER SOLUBLE. XXX in waterXXX

incidentally, it occurs to me that you should also be aware that flammable means the same as inflammable. Don’t ask me why. Just a crazy-ass thing that happened im Volksmund im Laufe der Zeit.

AI : liquids with flashpoint below 21°C
AII: liquids with flashpoint from 21°C till 55°C
AIII: liquids with flashpoint FROM ABOVE 55°C TO 100°C

hazard category type B:

  • liquids having a flashpoint below 21°C AND WHICH XXX thatXX dissolve in
    water or whose flammable constituents disolve in water

note generally:
A liquid with a lower flashpoint is more dangerous than a
liquid with a higher flashpoint!

rules about flammable liquids handling okay, but I would probably write: Rules for the handling of flammable liquids. or

Rules for handling flammable liquids
