6. Safety

6.1 Gas Piping

Gas piping inside the Test Unit is made of nylon tube; outside, viton tube. Gas is very dangerous if
it leaks. Consult the Tanaka authorized distributor for periodical gas leakage check.

THE

TESTER IS NOT EQUIPPED WITH A GAS LEAKAGE DETECTOR

.

6.2 Prevention of Sample from Catching Fire

In case the temperature at which the first test flame application is made is above the flash point of
the specimen, there is a danger: the specimen catches a fire to blaze up.
So as to prevent such a danger in advance, for testing a sample of unknown flash point, use the
Special mode in Section

3.5

. Be sure to arrange at least one proper person in your test room, lab,

etc., when testing, to cope with possible accidents.

6.3 Manual Fire Containment

In case the specimen catches a fire unexpectedly, push manual fire containment switch to
extinguish a fire. Push once more to stop buzzer, and then push RESET key to return MAIN screen.
