| Entsorgungsverfahren | SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure 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, aquatic, and plant lifeand conformance with environmental and public health regulations. |
|---|
| Verschüttetes entsorgen | Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Cover the spilled material with dry sand. Sweep spilled substance into covered dry plastic containers. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT wash away into sewer. |

| Human Toxicity Excerpts | /SIGNS AND SYMPTOMS/ Solution contains /the hydrolysis product/ methyl alcohol, and is toxic and corrosive to tissue./SIGNS AND SYMPTOMS/ Ingestion causes irritation of mouth and stomach./SIGNS AND SYMPTOMS/ Corrosive. The substance is corrosive to the eyes, the skin and the respiratory tract. Inhalation of dusts may cause lung edema. The effects may be delayed. |
|---|
| Non-Human Toxicity Excerpts | /LABORATORY ANIMALS: Acute Exposure/ In a rabbit eye irritation test, a 30% solution in methanol was corrosive./LABORATORY ANIMALS: Acute Exposure/ A 30% solution in methanol was corrosive to rabbit skin./LABORATORY ANIMALS: Acute Exposure/ Corrosive in a rabbit skin irritation test. An 80% aqueous preparation was examined. Since sodium methoxide hydrolyzes rapidly in water to NaOH and methanol, the corrosive action was the result of the NaOH. |
|---|
| Antidote and Emergency Treatment | The symptoms of lung edema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered. |
