Health hazards

powder mixture) May cause skin and eye irritation. May cause irritation of the upper respiratory tract (nose, mouth and/or throat), resulting in sneezing coughing and sore throat. Long-term respiratory exposure exceeding exposure limits may damage the lungs, leading to impairment of lung capacity. ----------------------------------------------------------------------------- The acute and chronic health effect statements below are for the pure chemicals only, unless noted.

Potential Acute Health Effects

1,3,5-Triglycidyl Isocyanurate) INGESTION: Moderately toxic. Symptoms are not fully known, may include loss of appetite and nose bleeding. INHALATION: Irritating to upper respiratory tract. May cause nosebleeds. EYE CONTACT: Irritating. SKIN CONTACT: Irritating. Can be absorbed through the skin in harmful amounts. Effects similar to ingestion. A COMMERCIAL POLYESTER POWDER MIXTURE CONTAINING 5% TGIC WAS TESTED IN RATS (SAFEPHARM (UK) 1998) FOR ACUTE ORAL TOXICITY WITH THE FOLLOWING RESULTS: LD50:>5000 mg/Kg (m/f) (TITANIUM DIOXIDE) INGESTION: Low oral toxicity. No toxic effects due to ingestion are described in literature. INHALATION: Irritating to upper respiratory tract. EYE CONTACT: Irritating. (ALUMINUM HYDROXIDE) Dust exposure causes eye irritation; basic eye burns are possible depending upon the duration of contact. This material is reported to exhibit a low order of toxicity via inhalation & ingestion. Prolonged skin contact may result in minor mechanical irritation. (SILICA, AMORPHOUS) Contact with dust may include eye irritation (discomfort, tearing or blurring of vision) or slight skin irritation (discomfort or rash). Overexposure to dust by inhalation may cause temporary lung irritation (cough, discomfort or difficulty in breathing).

Potential chronic health

1,3,5-Triglycidyl Isocyanurate) Irritation of eyes, skin and respiratory tract; loss of appetite, may cause nosebleeds; toxic by ingestion and if absorbed through the skin. Prolonged or repeated contact may cause skin sensitization. TGIC has shown mutagenic activity in laboratory cells culture test and laboratory animals. Based on those studies, TGIC has been classified as "Possible Human Germ Cell Mutagen", and capable of causing permanent heritable damage in reproductive cells on humans. Overexposure can result in toxic effects on liver and lungs. (TITANIUM DIOXIDE) Laboratory studies show that inhalation exposure to high levels (250 mg/kg) of Titanium Dioxide causes cancerous tumors in rats. This ----------------------------------------------------------------------------- response occurs at lower exposure levels and may be due to the high levels overwhelming normal lung clearance mechanisms. The relevance of this data to humans is not significant where the TLV is observed. MEDICAL CONDITIONS PRONE TO AGGRAVATION BY OVEREXPOSURE: (1,3,5-Triglycidyl Isocyanurate) Respiratory illness & dermatitis may be aggravated by excessive exposure. (SILICA, AMORPHOUS) Preexisting lung diseases may increase susceptability to the effects of excessive amorphous silica dust exposure.
