Safety Rules

Before beginning any of these

experiments, please read carefully

through the following list. Make an

effort right from the start to work

properly, so you can avoid any

possible risks.

1. Read these instructions before use, follow them

and keep them for reference.

Pay special attention to the quantity speciﬁcations

and the sequence of the individual steps. Only

perform experiments that are described in this

instruction manual.

2. Keep young children, animals and those not

wearing eye protection away from the

experimental area.

3. Always wear eye protection. If you wear corrective

eyeglasses, you will need protective goggles for

those who wear corrective eyeglasses. When

working, wear appropriate protective clothing, like

an old smock and smooth ﬁngered gloves.

4. Store this experimental set out of reach of children

under 10 years of age.

5. Clean all equipment after use.

6. Make sure that all containers are fully closed and

properly stored after use. Carefully close the

chemical vials after use and return them to their

places in the experiment kit.

7. Ensure that all empty containers are disposed of

properly.

8. Wash hands after carrying out experiments.

Chemicals that accidentally get onto your skin must

be rinsed off immediately under running water.

9. Do not use any equipment which has not been

supplied with the set or recommended in the

instructions for use.

10. Do not eat or drink in the experimental area. Do

not use any eating, drinking, or other kitchen

utensils for your experiments unless it is speciﬁcally

recommended. Any containers or equipment you use

in your work should not be used in the kitchen

afterwards.

When you use liquid food products

(such as vinegar, lemon juice, and

mineral water) for an experiment,

transfer the required amount to a

clean container, such as a yogurt

cup. Keep this separate from the

original container and any kitchen

items used for cooking and eating.

Vinegar

11. Do not allow chemicals to come into contact with

the eyes or mouth.

12. Do not replace foodstuffs in original container.

Dispose of immediately. If you are investigating

food products (such as table salt or vinegar), transfer

the required quantity into a clean, empty container

(do not use the double-headed measuring spoon for

this). Make a note on the container of what it

contains and the date it was ﬁlled.

13. The tealight candle required for some of the

experiments has to be placed on a ﬁre-resistant

surface (such as an old plate). Extinguish the fl me

after the experiment has ended, if not earlier, and

extinguish it if you have to leave the experiment

area even just for a moment.

14. During experiments with open fl me, be sure that

there are no fl mmable objects or liquids nearby.

Keep a bucket or box of sand ready in case you need

to put out a ﬁre. If the ﬁre can’t be extinguished

right away, notify the ﬁre department immediately.

15. Any ﬁlled container or experimental apparatus that

has to remain standing for a longer period of time

has to be labeled and stored out of the reach of

children and animals.

16. Get any additionally required materials ready before

starting an experiment.

17. Handle breakable materials (e.g., the glass test

tubes) carefully.

Also note the information on the chemical vial labels,

the information about hazardous substances on page 7,

and the safety notes accompanying the individual

experiments. With additionally required materials, also

take note of the warnings on their packaging.
