10.3 Possibility of hazardous reactions

Fire and Explosion Hazards: Flammable liquid. Combustion may produce irritants and toxic gases. Closed containers may rupture violently when heated. May be decomposed by mild shock. Decomposes when heated; if diluted with toluene, its explosive properties are practically eliminated.3-BROMOPROPYNE is soluble in alcohol, ether, chloroform, carbon tetrachloride and carbon disulfide. It is highly flammable and a dangerous fire risk, sensitive to shock. It is used in organic syntheses, preparation of resins and perfume intermediates [Hawley]. There is a high danger of formation of explosive metal acetylides, when this compound comes in contact with copper, high-copper alloys, mercury, or silver.

10.4 Conditions to avoid

12.2 Persistence and degradability

AEROBIC: Biodegradation of 3-bromo-1-propyne is not expected to compete with chemical degradation processes based on similar half-lives measured for this substance in sterile soil (0.37-11 days) and nonsterile soil (0.046-12 days)(1-3).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated for 3-bromo-1-propyne(SRC), using a water solubility of 1.49X10+4 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

Highly flammable. Toxic if swallowed. Irritating to eyes, respiratory system and skin. Harmful by inhalation. Possible risk of harm to the unborn child. Vapours may cause drowsiness and dizziness.
Potential Health Effects
Causes eye irritation. Lachrymator (substance which increases the flow of tears).
Causes skin irritation. Prolonged and/or repeated contact may cause defatting of the skin and dermatitis.
Harmful if swallowed. Ingestion of large amounts may cause CNS depression.
Causes respiratory tract irritation. Inhalation of high concentrations (>200 ppm) of toluene are clearly associated with CNS encephalopathy, headache, depression, lassitude (weakness, exhaustion), impaired coordination, transient memory loss, and impaired reaction time.
Prolonged or repeated skin contact may cause defatting and dermatitis. Repeated exposure in combination with constant, loud noise can produce hearing loss and dizziness. Chronic hydrocarbon abuse (for example, sniffing glue or light hydrocarbons such as contained in this material) has been associated with irregular heart rhythms and potential cardiac arrest. Toluene abuse has been linked with kidney disease, as evidenced by blood, protein, & pus in the urine, accompanied by elevated serum creatinine, decreased urinary output, & metabolic & renal tubular acidosis. Although kidney toxicity has not been common in cases of occupational toluene exposure, there has been at least one report of renal toxicity following a 40-year occupational toluene exposure. Toluene does not cause the severe injury to the bone marrow that is characteristic of benzene poisoning.

  Eyes: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical aid.
In case of contact, flush skin with plenty of water. Remove contaminated clothing and shoes. Get medical aid if irritation develops and persists. Wash clothing before reuse.
If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. Get medical aid.
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:

  General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Flammable liquid and vapor. Approach fire from upwind to avoid hazardous vapors and toxic decomposition products. Vapors are heavier than air and may travel to a source of ignition and flash back. Vapors can spread along the ground and collect in low or confined areas. May accumulate static electricity.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or appropriate foam.

  General Information: Use proper personal protective equipment as indicated in Section 8.
Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Clean up spills immediately, observing precautions in the Protective Equipment section. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation.
Approach spill from upwind. Keep unnecessary and unprotected personnel away. Use water spray to cool and disperse vapors and protect personnel.

Section 7 - HANDLING and STORAGE
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Avoid mechanical shock and friction. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Use only with adequate ventilation. Keep away from heat, sparks and flame. Avoid breathing vapor or mist. Pure vapor will be uninhibited and may polymerize in vents or other confined spaces.
Keep away from sources of ignition. Keep container closed when not in use. Flammables-area. Keep refrigerated. (Store below 4C/39F.) Separate from oxidizing materials.

  Engineering Controls:
Use explosion-proof ventilation equipment. Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.
