EVIDENCE OF RICHARD CREESE TERRY GOVERNMENT ANALYST - SWORN.
کھا
My name is Richard Creese Terry and I am the Assis-
tant Government Chemist. I have visited the "Kwong Tung"
on Monday xxx morning the 2nd February, 1948.
I was
shown where the fire had broken out. I collected various
samples of goods lying around in the vicinity of the fire.
Subsequent to my visit and collection of samples, I receivea
other samples from the Western Police but I have no know-
when
ledge as to к they were collected. The samples I
collected comprised, (a) a material occurring in readish
lumps,
(b) a white powder,
(c) a white powder,
(d) a white powder,
(e), (f) & (g) charred sacking.
Sample (a) consisted of a vegetable tanning extract
of a similar nature to cutch.
Samples (b), (c) & (a) were identical and consisted
of potassium chlorate.
Sample (a) is in no way dangerous and burns with great
aifficulty.
Samples (b), (c), and (d) Potassium chlorate must be
regarded as a dangerous chmical. It is dangerous in itself
& also when in contact with other substances.
In my opinion the potassium chlorate was/
concerned
in the fire. Potassium chlorate has been known to explode
itself, and inflame organic matter in contact with it, on
percussion. In cases where potassium chlorate inflames
organic matter the matter would probably burst into flames
while the potassium chlorate decomposes forming a white smoke.
