In case of fire in the surroundings: all extinguishing agents allowed. Cool exposed containers with water.

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!

Triage procedures and medical management guidelines. (See ATSDR Toxicology Profile on cyanide and ATSDR medical management guidelines on hydrogen cyanide.)

• 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.

Triage procedures and medical management guidelines - see ATSDR Toxicology Profile on cyanide and ATSDR medical management guidelines on hydrogen cyanide.

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.

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.

OSHA PEL: N/A
NIOSH REL: C 0.3 ppm (0.6 mg/m³)
ACGIH TLV: 0.3 ppm; as (ceiling value) (ACGIH 2002).
NIOSH IDLH: N/A

Patients/victims: Wet contaminated clothing should be removed and the underlying skin washed with soap and water or water alone for 2-3 minutes.

NFPA 704 Signal:

Special - N/A

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:
unknown
