EXPOSURE
AVOID ALL CONTACT!

•INHALATION Burning sensation. Cough. Laboured breathing. Shortness of breath. Symptoms may be delayed (see Notes).
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
•SKIN Skin burns. Pain. Blisters.
Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
•EYES Corrosive. Redness. Pain. Severe deep burns.
Face shield, or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION Corrosive. Abdominal cramps. Burning sensation. Headache. Weakness.
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Do NOT induce vomiting. Rest. Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place.
Separated from strong oxidants, and alkalis. Ventilation along the floor.

ICSC: 1172 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

PHYSICAL STATE; APPEARANCE:
COLOURLESS VISCOUS LIQUID.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
Reacts with oxidants, sulfuric acid, nitric acid and alkalis.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.


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 will be reached rather slowly on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
Corrosive. The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of its aerosol may cause lung oedema (see Notes). The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point: about 320°C
Relative density (water = 1): about 0.91
Solubility in water: none
Relative vapour density (air = 1): 12.0

ENVIRONMENTAL
DATA


N O T E S

Technical dinonyl phenol is a mixture of various isomers and may contain up to 15% nonyl phenol. The CAS number of 2,4-dinonyl phenol is 137-99-5. The substance is combustible but no flash point is available in literature. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.
