Important Data
|
Physical State; Appearance:
COLOURLESS
MOBILE LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The vapour is heavier than air
and may travel along the ground; distant ignition possible.
Chemical Dangers:
The substance can readily polymerize
due to warming or
under the influence of light or peroxides,
with fire or explosion hazard.
Reacts
violently with
strong oxidants
.
Occupational Exposure Limits:
TLV: 10 ppm as TWA, 15 ppm as STEL; A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2004).
MAK:
Carcinogen category: 3A;
(DFG 2004).
OSHA PEL: none
NIOSH REL: C 4 ppm (15 mg/m3) 15-minute
NIOSH IDLH: N.D. See: IDLH INDEX
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation
and
by ingestion.
Inhalation Risk:
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
is irritating to
the eyes
,
the skin
and
the respiratory tract
.
The substance may cause effects on the
lungs
, resulting in
tissue lesions
.

|
N O T E S
|
Other melting points: -100°C.
Use of alcoholic beverages enhances the harmful effect.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
The stabilizing quality of hydroquinone is limited to 60 days. For prolonged storage, another inhibitor, such as diphenylamine, is recommended.
