Verschüttetes entsorgenPersonal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.
Eye PreventionWear face shield or eye protection in combination with breathing protection.
Fire PreventionNO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust. Prevent build-up of electrostatic charges (e.g., by grounding).
Inhalation RiskA harmful concentration of airborne particles can be reached quickly when dispersed.
Skin PreventionProtective gloves.
Exposure PreventionAVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!
Ingestion PreventionDo not eat, drink, or smoke during work. Wash hands before eating.
Inhalation PreventionUse local exhaust or breathing protection.
Gesundheitliche AuswirkungenBreathing or swallowing, or skin contact with organotins, can interfere with the way the brain and nervous system work, causing death in severe cases. Organic tin compounds may also damage the immune and reproductive system. (L307, L308)
Unerwünschte WirkungenNeurotoxin - Other CNS neurotoxin
ExpositionspfadeThe substance can be absorbed into the body by inhalation and by ingestion.Oral (L308)inhalation (L308)dermal (L308)
ToxizitätsübersichtOrganotin compounds produce neurotoxic and immunotoxic effects. Organotins may directly activate glial cells contributing to neuronal cell degeneration by local release of pro-inflammatory cytokines, tumor necrosis factor-_, and/or interleukins. They may also induce apoptosis by direct action on neuronal cells. Organotin compounds stimulate the neuronal release of and/or decrease of neuronal cell uptake of neurotransmitters in brain tissue, including aspartate, GABA, glutamate, norepinephrine, and serotonin. This may be either a contributing factor to or result of the neuronal cell loss. The immunotoxic effects of organotins are characterized by thymic atrophy caused by the suppression of proliferation of immature thymocytes and apoptosis of mature thymocytes. Organotin compounds are believed to exert these effects by suppressing DNA and protein synthesis, inducing the expression of genes involved in apoptosis (such as nur77), and disrupting the regulation of intracellular calcium levels, giving rise to the uncontrolled production of reactive oxygen species, release of cytochrome c to the cytosol, and the proteolytic and nucleolytic cascade of apoptosis. The suppression of proliferation of immature thymocytes further results in the suppression of T-cell-mediated immune responses. Organotins are also endocrine disruptors and are believed to contribute to obesity by inappropriate receptor activation, leading to adipocyte differentiation. Inorganic tin triggers eryptosis, contributing to tin-induced anemia. (L308, A182, A184)
Signs and SymptomsHeadache. Confusion.Redness. Pain. Further see Inhalation.Inorganic or organic tin compounds placed on the skin or in the eyes can produce skin and eye irritation. (L308)
ICSC Environmental DataThe substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal.
Carcinogen ClassificationNo indication of carcinogenicity to humans (not listed by IARC).
