Important Data
|
Physical State; Appearance:
COLOURLESS CRYSTALS
Physical Dangers:
Chemical Dangers:
The substance decomposes
under the influence of water
producing
cyanamide (see ICSC0424),
ammonia
,
calcium hydroxide
and
acetylene
, causing fire and explosion hazard.
Attacks many metals forming flammable/explosive gas (hydrogen - see ICSC 0001).
Occupational Exposure Limits:
TLV: 0.5 mg/m3
|
Routes of Exposure:
The substance can be absorbed into the body
in hazardous amounts
by inhalation
and
by ingestion.
Inhalation Risk:
A harmful concentration of airborne particles can be reached quickly when dispersed
.
Effects of Short-Term Exposure:
The substance
is severely irritating to
the eyes
and
the respiratory tract
.
Effects of Long-Term or Repeated Exposure:
|
|
Physical
Properties
|
Decomposes when heated
Density: 2.3
g/cm3
|
Solubility in water: reaction
|
|
Environmental
Data
|
This substance may be hazardous in the environment; special attention should be given to aquatic organisms.
|
|
N O T E S
|
In combination with even small amounts of alcohol the substance causes effects on cardiovascular and central nervous systems resulting in flushing, palpitation, hypotension and hyperventilation. The effects may be delayed. Commercial calcium cyanamide is a crystalline substance which contains trace amounts of calcium carbide which may produce acetylene in production vessels or containers.
Reacts violently with fire extinguishing agents such as water.
UN 1403: Calcium Cyanamide with more than 0.1% calcium carbide.
Transport Emergency Card: TEC (R)-43GW2-II+III.
NFPA Code: H-; F3; R1; W
Card has been partially updated in January 2008: see Occupational Exposure Limits.
