EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
Inhalation Burning sensation. Cough. Laboured breathing. Nausea. Vomiting.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Refer for medical attention.

CYCLOHEXYLAMINE ICSC: 0245
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO YELLOW LIQUID, WITH PUNGENT ODOUR.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic and corrosive fumes including nitrogen oxides. The substance is a strong base, it reacts violently with acid and is corrosive. Reacts violently with strong oxidants causing fire hazard. Attacks aluminium, copper, zinc.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 10 ppm as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK: 2 ppm, 8.2 mg/m; Peak limitation category: I(2); Pregnancy risk group: C; (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. The substance may cause effects on the central nervous system.
