TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Foam, powder, carbon dioxide.
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.

EXPOSURE
PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!

•INHALATION
Local exhaust or breathing protection.
Fresh air, rest.
•SKIN
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
•EYES Redness. Pain.
Safety goggles, 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
Do not eat, drink, or smoke during work.
Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
WHITE POWDER OR GRANULE.

PHYSICAL DANGERS:
Dust explosion possible if in powder or granular form, mixed with air.

CHEMICAL DANGERS:
The substance may polymerize due to heating to more than 120°C for more than 12 hours, or under the influence of catalysts. The substance decomposes on burning producing toxic fumes including nitrogen oxides. Molten triglycidyl isocyanurate reacts rapidly with primary and secondary amines, carboxylic acids and anhydrides, thiols, phenols and alcohols.

OCCUPATIONAL EXPOSURE LIMITS:
TLV (as TWA): ppm; 0.05 mg/m3 (ACGIH 1998).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates severely the eyes. The substance may cause effects on the central nervous system, kidneys, liver, lungs and gastrointestinal tract , resulting in tissue lesions.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization. May cause heritable genetic damage in humans.

PHYSICAL
PROPERTIES

Melting point: 95°C
Solubility in water, g/100 ml at 25°C: 0.9 (technical grade)
Flash point: >170°C (technical grade)
Auto-ignition temperature: >200°C (technical grade)
Octanol/water partition coefficient as log Pow: -0.8 (technical grade)

ENVIRONMENTAL
DATA


N O T E S

Technical grade of this substance is a mixture of alpha and beta isomers.
