4.First-aid measures

4.1 Description of necessary first-aid measures

General advice

Consult a physician. Show this safety data sheet to the doctor in attendance.

If inhaled

Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.

In case of skin contact

First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention .

In case of eye contact

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

If swallowed

Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest. Refer for medical attention .

4.2 Most important symptoms/effects, acute and delayed

Inhalation: intolerable odor and irritation; respiratory injury may occur at higher levels. Ingestion causes irritation of mouth and stomach. Contact with either liquid or vapor may cause burns of eyes. Liquid produces frostbite-type of skin burn if free to evaporate; if confined to skin, burn may cause skin sensitization; not readily absorbed in toxic amounts. (USCG, 1999)

4.3 Indication of immediate medical attention and special treatment needed, if necessary

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Ethylene oxide and related compounds/

5.Fire-fighting measures

Personal protection: filter respirator for organic vapours of low boiling point adapted to the airborne concentration of the substance.

6.3 Methods and materials for containment and cleaning up

Personal precautions, protective equipment and emergency procedures: Wear respiratory protection. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Remove all sources or ifnition. Evacuate personnel to safe areas. Beware of vapors accumulating to form explosive concentrations. Vapors can accumulate in low areas...

9.Physical and chemical properties

10.Stability and reactivity

10.1 Reactivity

no data available

10.2 Chemical stability

Stable under recommended storage conditions.

10.3 Possibility of hazardous reactions

Dangerous fire hazard when exposed to heat, flame or powerful oxidizers.The vapour is heavier than air and may travel along the ground; distant ignition possible. The vapour mixes well with air, explosive mixtures are easily formed. As a result of flow, agitation, etc., electrostatic charges can be generated.Epoxides, such as 1,2-BUTYLENE OXIDE, are highly reactive. They polymerize in the presence of catalysts or when heated. Contact with anhydrous metal halides; amino, hydroxyl and carboxyl functions; inorganic acids and charcoal may cause polymerization. These polymerization reactions can be violent. Compounds in this group react with acids, bases, and oxidizing and reducing agents. They react, possibly violently with water in the presence of acid and other catalysts.

10.4 Conditions to avoid

no data available

10.5 Incompatible materials

Incompatible materials: Oxidizing agents.

10.6 Hazardous decomposition products

When heated to decomposition it emits acrid smoke and fumes.

11.Toxicological information

Acute toxicity

• Oral: LD50 rat (oral) 900 mg/kg body weight
• Inhalation: LC50 rat (inhalation, 4 hr) > 6,300 < 20,000 mg/cu m
• Dermal: no data available

Skin corrosion/irritation

no data available

Serious eye damage/irritation

no data available

Respiratory or skin sensitization

no data available

Germ cell mutagenicity

no data available

Carcinogenicity

Evaluation: No epidemiological data relevant to the carcinogenicity of 1,2-epoxybutane were available. There is limited evidence in experimental animals for the carcinogenicity of 1,2-epoxybutane. Overall evaluation: 1,2-Epoxybutane is possibly carcinogenic to humans (Group 2B). In making the overall evaluation, the Working Group took into consideration that 1,2-epoxybutane is a direct acting alkylating agent which is mutagenic in a range of test systems.

Reproductive toxicity

No information is available on the reproductive or developmental effects of 1,2-epoxybutane in humans. In a developmental inhalation study, the pregnancy rate of rabbits was reduced but birth defects were not observed at high doses; these results may be confounded by a high rate of maternal mortality. No reproductive or developmental effects were observed in an inhalation study of rats.

12.Ecological information

12.1 Toxicity

• Toxicity to fish: no data available
• Toxicity to daphnia and other aquatic invertebrates: no data available
• Toxicity to algae: no data available
• Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: 1-Butene oxide, present at 100 mg/L, reached 100% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test which classified the compound as readily biodegradable(1); 1,2-butanediol was formed as the degradation product(1). 1-Butene oxide failed the ready biodegradability test (OECD 301D, closed bottle, sewage sludge test) with 17% degradation after 29-30 days(2,3). In a CO2-Headspace test according to ISO 14593 (activated sludge, domestic, non-adapted), 80-90% degradation of 1-butene oxide was reached within 28 days which classified the compound as readily biodegradable(3,4). Using OECD Guideline 301A (new version, Ready Biodegradability: DOC Die Away Test), 80-90% degradation was reached within 28 days(3,4). A conclusion from the available test results is that 1-butene oxide is readily biodegradable(3).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for 1-butene oxide(SRC), using a log Kow of 0.68(1) and a regression-derived equation(2). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of 1-butene oxide can be estimated to be 10(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1-butene oxide is expected to have very high mobility in soil.

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
