FIRE |
Not combustible. Heating will cause rise in pressure with risk of bursting. Gives off irritating or toxic gases including cyanide gas in a fire.
|
N/A |
In case of fire in the surroundings: all extinguishing agents allowed. Cool exposed containers with water. |
EXPLOSION |
N/A |
N/A |
In case of fire: cool cylinder by spraying with water but avoid contact of the substance with water. |
ROUTE OF EXPOSURE |
|
Synopsis: |
Cyanogen Chloride has properties similar to riot control agents and it can cause irritation of the eyes, nose, and airways resulting in lacrimation (tearing), rhinorrhea (runny nose), and increased fluid production in the lungs. |
AVOID ALL CONTACT! |
(See ATSDR Toxicology Profile on cyanide and ATSDR medical management guidelines on hydrogen cyanide.)
|
Inhalation: |
- Runny nose (rhinorrhea).
- Sore throat.
- Drowsiness.
- Confusion.
- Nausea.
- Vomiting.
- Cough.
- Unconsciousness.
- Edema with symptoms which may be delayed (See Notes.)
|
Ventilation, local exhaust, or breathing protection.
Pressure demand, self-contained breathing apparatus (SCBA) (SCBA CBRN, if available) is recommended in response to non-routine emergency situations.
CBRN, Full Facepiece APR (when available) is recommended in non-routine, emergency situation environments less than IDLH but above REL or PEL levels.
|
Fresh air, rest. Half-upright position. Artificial respiration if indicated.
Seek medical attention immediately. |
Skin: |
Cyanogen Chloride is readily absorbed through intact skin causing systemic effects without irritant effects on the skin.
On contact with liquid frostbite may occur. The liquid may be absorbed.
Redness. Pain.
|
Cold-insulating gloves. Butyl rubber gloves. Teflon, Responder, or Tychem Protective clothing.
|
Frostbite: rinse with plenty of water, do NOT remove clothes.
Seek medical attention immediately. |
Eyes: |
On contact with liquid: frostbite.
Redness. Pain. Excess tears (lacrimation).
|
Face shield, or eye protection in combination with breathing protection.
|
First rinse with plenty of water for several minutes.
Seek medical attention immediately. |
Ingestion: |
N/A |
Do not eat, drink, or smoke during work. Wash hands before eating. |

DECONTAMINATION |
Patients/victims: Wet contaminated clothing should be removed and the underlying skin washed with soap and water or water alone for 2-3 minutes. Equipment: N/A
Environment: (See Spillage Disposal.)
|
SPILLAGE DISPOSAL |
Evacuate danger area! Consult an expert! Ventilation. NEVER direct water jet on liquid. Remove vapor cloud with fine water spray. Do NOT wash away into sewer. Chemical protection suit including self-contained breathing apparatus.
Storage: Fireproof if in building. Provision to contain effluent from fire extinguishing. Cool. |

IMPORTANT DATA |
PHYSICAL STATE; APPEARANCE:
Colorless compressed liquefied gas, with pungent odor.
PHYSICAL DANGERS:
The gas is heavier than air.
CHEMICAL DANGERS:
The substance decomposes on heating producing toxic and corrosive fumes (hydrogen cyanide, hydrochloric acid, nitrogen oxides). Reacts slowly with water or water vapor to form hydrogen chloride.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.
INHALATION RISK:
A harmful concentration of this gas in the air will be reached very quickly on loss of containment.
EFFECTS OF SHORT-TERM EXPOSURE:
The substance severely irritates the eyes with excessive tearing (lacrimation), the skin and the respiratory tract causing runny nose (rhinorrhea) and edema (fluid buildup in the lungs). Cyanides poison the vital organs of the body (for example the lungs and heart) including areas of the brain that regulates proper functioning of those organs. Exposure may result in convulsions, unconsciousness and in death. (See Notes.) Inhalation of the substance may cause lung edema (see Notes). The effects may be delayed. Rapid evaporation of the liquid may cause frostbite. Medical observation is indicated.
EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

NOTES |
| The occupational exposure limit value should not be exceeded during any part of the working exposure. The symptoms of lung edema (buildup of fluid in the lungs) often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Do NOT spray water on leaking cylinder (to prevent corrosion of cylinder). Turn leaking cylinder with the leak pointing up to prevent escape of gas in liquid state. |
