The National Library of Medicine does not test products nor does it evaluate information from the product label or the MSDS. (What is an MSDS?)
Acute Health Effects:
Potential Health Effects and Symptoms
Inhalation: Exposure to excessive amounts of dust may cause physical irritation to respiratory tract.
Ingestion: Practically non-toxic. Ingestion is a minor route of entry for intended use of this product
Eye: May cause transient slight irritation.
Skin: May be non-irritant.
Medical Conditions Generally Known to be Aggravated by Exposure: Not determined.
Chronic Health Effects:
Prolonged inhalation of excessive amounts of dust may cause lung damage. Use of this product as intended does not result in inhalation of excessive amounts of dust.
Not available for acute exposure.
For chronic exposure: Muhle et al. reported pulmonary response upon chronic inhalation exposure in rats to a toner enriched in respirable-sized particles compared to commercial toner. No pulmonary change was found at 1 mg/m3 which is most relevant to potential human exposure. A minimal to mild degree of fibrosis was noted in 22% of the animals at 4 mg/m3, and a mild to moderate degree of fibrosis was observed in 92% of the animals at 16 mg/m3.
These findings are attributed to lung overloading
0 = Minimal; 1 = Slight; 2 = Moderate; 3 = Serious; 4 = Severe; N = No information provided by manufacturer; * = Chronic Health Hazard
Avoid breathing dust. Use with adequate ventilation. Keep out of the reach of children. Keep away from oxidizing materials.
DO NOT put toner or toner container into fire; heated toner may cause severe burns. DO NOT shred a toner container, unless dust-explosion preventing measures are taken. Finely dispersed particles form explosive mixtures in air. Disposal should be subject to federal, state and local laws.
