| Reactivity Profile | Pure 1,4-BUTYNEDIOL is non-explosive. Small amounts of certain impurities-alkali hydroxides, alkaline earth hydroxides, halides-may cause explosive decomposition upon distillation. Butynediol should not be treated with basic catalysts in the absence of a solvent at room temperature, and its stability is less with elevated temperatures. In strong acids, contamination with mercury salts can also result in violent decomposition. [NFPA 491M 1991]. |
| Chemical Dangers | Decomposes on heating. This produces toxic and corrosive fumes. Reacts violently with anhydrides, acid chlorides, mercury salts and alkaline hydroxides or chlorides. This generates explosion hazard. |
| 소화 | Fire Extinguishing Agents: Water, alcohol foam, dry chemical, or carbon dioxide (USCG, 1999)Use water spray, alcohol-resistant foam, dry powder, carbon dioxide. |
| 응급 조치 | Fresh air, rest. Half-upright position. Refer immediately for medical attention.Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer immediately for medical attention.Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention. |
| 누출 비상 조치 | · CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. |
| 응급 처치 | SKIN CONTACT: wash affected skin area thoroughly with water.General First Aid: |
| 안전 보관 | Separated from incompatible materials. See Chemical Dangers. Cool. Store in an area without drain or sewer access. |
| 노출 관리 및 개인 보호 | · Wear positive pressure self-contained breathing apparatus (SCBA).0.1 [ppm] |

Keep run-off water out of sewers and water sources. |

| 비화재 누출 대응 | Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]: |
| 처리 방법 | 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. |
| 누출 처리 | Evacuate danger area! Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. 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. |
| Preventive Measures | 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.SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit 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.Personnel protection: Avoid breathing vapors. Keep upwind. ... Do not handle broken packages unless wearing appropriate personal protective equipment. If contact with the material anticipated, wear appropriate chemical protective clothing.If material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors. |

| 환경 거동 | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1(SRC), determined from a water solubility of 3.74X10+6 mg/L(2) and a regression-derived equation(3), indicates that 1,4-butynediol is expected to have very high mobility in soil(SRC). Volatilization of 1,4-butynediol from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.7X10-11 atm-cu m/mole(SRC), derived from its vapor pressure, 5.56X10-4 mm Hg(4), and water solubility(2). 1,4-Butynediol is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(4). 1,4-Butynediol has been shown to biodegrade 90% in 4 days using a sewage sludge(5)therefore, biodegradation is expected to be an important environmental fate process in soil(SRC).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1(SRC), determined from a water solubility of 3.74X10+6 mg/L(2) and a regression-derived equation(3), indicates that 1,4-butynediol is not expected to adsorb to suspended solids and sediment(SRC).

Vapor-phase 1,4-butynediol is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be 11 hours(SRC), calculated from its rate constant of 3.4X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). 1,4-Butynediol does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight(4). |

| Human Toxicity Excerpts | /HUMAN EXPOSURE STUDIES/ Ten workers with suspicion of allergic contact eczema who were probably accidentally exposed to butynediol were asked for voluntary patch testing for possible sensitisation6 of these 10 workers were willing to undergo the test.

Furthermore, formaldehyde which is a precursor for synthesis and an impurity in technical grade butynediol was also tested.

| Artificial Pollution Sources | 1,4-Butynediol's production and use as an intermediate, corrosion inhibitor, electroplating brightener, polymerization accelerator, stabilizer for chlorinated hydrocarbons and cosolvent for paint and varnish removal(1) may result in its release to the environment through various waste streams. Its use as a defoliant(1) (not regristered for this application in the US(2)) will result in its direct release to the environment(SRC). |
