| Expositionsschutz und Persönliche Schutzausrüstung | · Wear positive pressure self-contained breathing apparatus (SCBA).TIH (Toxic Inhalation Hazard) - Term used to describe gases and volatile liquids that are toxic when inhaled. Some are TIH materials themselves, e.g., chlorine, and some release TIH gases when spilled in water, e.g., chlorosilanes. [ERG 2016]. |
| Brandbekämpfungsverfahren | If material on fire or involved in fire: use dry chemical, dry sand, or carbon dioxidedo not use water on material itselfif large quantities of combustibles are involved, use water in flooding quantities as spray and foguse water spray to knock down vaporscool all affected containers with flooding quantities of waterapply water from as far a distance as possible.Use water spray, dry chemical, or carbon dioxide to extinguish small fires. Use water to keep fire-exposed containers cool. Approach fire from upwind to avoid hazardous vapors and toxic decomposition products.Wear special protective clothing and positive pressure self-contained breathing apparatus. |
| Lagerbedingungen | SRP: Operations involving entry into tanks or closed vessels, and emergency situations, require consideration of potentially oxygen deficient, or "immediately dangerous to life and health" IDLH environments. This may necessitate use of a self-contained breathing apparatus (SCBA), or a positive pressure supplied air respirator.Store in a cool, dry, well-ventilated location. Separate from acids, alkalies, oxidizing materials, and water. Outside or detached storage is preferred.All containers, pipes, apparatus, installations, and structures used for the manufacture, storage, transport, or use of these substances must be of material resistant to corrosive substances or be protected by suitable coatings ... All containers or receptacles should be clearly labelled to indicate their contents and should bear the danger symbol for corrosives. /Corrosive substances/ |
| Reinigungsverfahren | SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.Eliminate all ignition sources. Stop or control the leak, if this can be done without undue risk. Use water spray to cool and disperse vapors and protect personnel. Spills can be neutralized by flushing with large quantities of water followed by treatment with sodium bicarbonate. Control runoff and isolate discharged material for proper disposal.Environmental considerations - land spill: dig a pit, pond, lagoon, holding area to contain liquid or solid material /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner/dike surface flow using soil, sand bags, foamed polyurethane, or foamed concreteabsorb bulk liquid with fly ash, cement powder, or commercial sorbents.Environmental considerations - water spill: use natural barriers or oil spill control booms to limit spill travelremove trapped material with suction hoses.Environmental considerations - air spill: apply water spray or mist to knock down vapors. |

| Entsorgungsverfahren | SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air qualitypotential migration in soil or watereffects on animal and plant lifeand conformance with environmental and public health regulations. |
| Preventive Measures | SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.SRP: Contaminated protective clothing should be segregated in a manner that results in no direct personal contact by personnel who handle, dispose of, or clean the clothing. Quality assurance procedures to confirm the efficacy of the cleaning procedures should be implemented prior to the decontaminated protective clothing being returned for reuse by the workers. Contaminated clothing (including shoes/socks) should not be taken home at end of shift, but should remain at employee's place of work for cleaning.SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants. Ensure that the local ventilation moves the contaminant away from the worker.If material not on fire and not involved in fire: keep sparks, flames, and othr sources of ignition awaykeep material out of water sources and sewersbuild dikes to contain flow as necessaryuse water spray to knock down vaporsdo not use water on material itselfneutralize spilled material with crushed limestone soda ash, or lime.For more Preventive Measures (Complete) data for Trichloropropylsilane (6 total), please visit the HSDB record page. |

| Unerwünschte Wirkungen | Dermatotoxin - Skin burns. |
| Human Toxicity Excerpts | /SIGNS AND SYMPTOMS/ Acute inhalation exposure may result in sneezing, choking, laryngitis, dyspnea (shortness of breath), respiratory tract irritation, and chest pain. Higher exposure can cause pulmonary edema, a medical emergency that can be delayed for several hours. This can cause death. Bleeding of nose and gums, ulceration of the nasal and oral mucosa, pulmonary edema, chronic bronchitis, and pneumonia may also occur. If the eyes have come in contact with dimethyldichlorosilane, irritation, pain, swelling, corneal erosion, and blindness may result. Dermatitis (red, inflamed skin), severe burns, pain, and shock generally follow dermal exposure. Inhalation irritates mucous membranes. Severe gastrointestinal damage may occur. Vapors cause severe eye and lung injury. Upon short contact, second and third degree burns may occur. Signs and symptoms of acute ingestion of dimethyldichlorosilane may be severe and include increased salivation, intense thirst, difficulty swallowing, chills, pain, and shock. Oral, esophageal, and stomach burns are common. /Dimethyldichlorosilane//SIGNS AND SYMPTOMS/ Inhalation irritates mucous membranes. Contact with liq causes severe burns of eyes and skin ... Vapors cause severe irritation of eyes and throat and can cause eye and lung injury. They cannot be tolerated even at low concn.

These data suggest that the acute toxicity of chlorosilanes is due to the hydrogen chloride hydrolysis productacute toxicity of the chlorosilanes is both qualitatively (based on clinical signs) and quantitatively (based on molar equivalents of hydrogen chloride) similar to that of HCl. Complete hydrolysis of one mole of a monochlorosilane would yield a maximum of one mole of hydrogen chloride. Complete hydrolysis of a dichlorosilane would yield a maximum of two moles of hydrogen chloride, complete hydrolysis of a trichlorosilane would yield a maximum of three moles of hydrogen chloride, and complete hydrolysis of tetrachlorosilane would yield a maximum of four moles of hydrogen chloride. /Chorosilanes//OTHER TOXICITY INFORMATION/ /Via inhalation/ they have a corrosive action when brought into contact with mucous membranes. /Chlorosilanes/ |
| Environmental Abiotic Degradation | Silane compounds decompose upon contact with water or steam to produce heat and toxic and corrosive fumes of hydrogen chloride. Silane ignites spontaneously in air(1,2). With a little ammonia, it forms a self-igniting product(1). /Chlorosilanes/ |
| Probable Routes of Human Exposure | According to the 2006 TSCA Inventory Update Report, the number of persons reasonably likely to be exposed in the industrial manufacturing, processing, and use for trichloropropylsilane is 100-999the data may be greatly underestimated(1). |
| Environmental Fate/Exposure Summary | Chlorosilane compounds' production and use as intermediates for silicone products may result in their release to the environment through various waste streams. However, these compounds decompose to release hydrogen chloride upon contact with water or steam. Therefore, volatilization, biodegradation, and bioconcentration are not expected to be important environmental fate processes. /Chlorosilanes/ (SRC) |
