EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE!

Inhalation Abdominal pain. Blue lips or finger nails. Blue skin. Confusion. Convulsions. Cough. Dizziness. Headache. Nausea. Sore throat. Unconsciousness.
Local exhaust or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin Redness. Pain.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes Redness. Pain.
Safety goggles, 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 (See Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give a slurry of activated charcoal in water to drink. Refer for medical attention.

RESORCINOL ICSC: 1033
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALS. TURNS PINK ON EXPOSURE TO AIR, LIGHT OR ON CONTACT WITH IRON.

PHYSICAL DANGERS:
As a result of flow, agitation, etc., electrostatic charges can be generated.

CHEMICAL DANGERS:
Reacts with strong oxidants ammonia and amino compounds causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 10 ppm as TWA; 20 ppm as STEL; A4; (ACGIH 2003).
EU OEL: 10 ppm, 45 mg/m, as TWA; (EU 2000).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20C; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract. The substance may cause effects on the blood, resulting in formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
In rare cases, repeated or prolonged contact may cause skin sensitization.
PHYSICAL PROPERTIES
Boiling point: 280C
Melting point: 110C
Density: 1.28 g/cm^3
Solubility in water, g/100 ml: 140
Vapour pressure, Pa at 20C: 0.065
Flash point: 127C c.c.
Auto-ignition temperature: 607C
Explosive limits, vol% in air: 1.4-?
Octanol/water partition coefficient as log Pow: 0.79-0.93
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
Depending on the degree of exposure, periodic medical examination is indicated. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Do NOT take working clothes home.
