2. HEALTH HAZARD INFORMATION

 

Swallowed

No significant health effects could be found.

Eye

Mechanical action arising from eye contact (action of dust) may cause slight temporary irritation of the mucosa.

Skin

Slightly irritative.

Inhaled

Irritant to mucous membranes and the respiratory tract.

According to the present state of knowledge this pigment is physiologically harmless; under extreme conditions, however, mechanical action arising from eye contact (action of dust) may cause slight temporary irritation of the mucosa.

If symptoms occur seek medical attention.

In case of eye contact rinse with plenty of water. If irritation of the eyes persists, consult a doctor (ophthalmologist).

Wash affected areas thoroughly with mild soap and water.

Remove from contaminated area immediately, avoid becoming a casualty. If NOT breathing apply artificial resuscitation.

Ensure an eye bath and safety shower are available and ready for use.

Treat symptomatically based on judgement of doctor and individual reactions of patient.

Toxicological tests on chemically identical products yielded the following

results :

Oral LD50 = >5000 mg/kg (Rat)

 

3. PRECAUTIONS FOR USE

 

No exposure standard has been established for this particular material, however the following is recommended for nuisance dust : TWA 10 mg/m3 (total dust) or 5 mg/m3 (respirable dust).

Ensure workplace is well ventilated to maintain airborne concentrations below standards.

Eye protection : goggles Respiratory protection : dust-protection mask if the exposure limit is exceeded. Wash hands and face thoroughly after handling and before work breaks, eating, drinking, smoking and using toilet facilities.

5 OTHER INFORMATION

 

Ecotoxicological tests on chemically identical products yielded the following results : Acute fish toxicity : Golden orfe (Leuciscus idus) LCo > 1000 mg/L Acute bacterial toxicity : No harmful effect on Pseudomonas putida > 1000 mg/L As the product is practically insoluble in water, it is separated in almost any filtration and sedimentation process.
