Diamond	Hazard	Value	Description
3 3 4	Health	3	Can cause serious or permanent injury.
	Flammability	3	Can be ignited under almost all ambient temperature conditions.
	Instability	4	Readily capable of detonation or explosive decomposition or explosive reaction at normal temperatures and pressures.
	Special

A colorless to light yellow liquid substance with a sharp odor. Flash point 65°F. Denser than water and insoluble in water. Vapors are heavier than air. May be irritating to skin and eyes. Used to make other chemicals. It may decompose explosively with mild shock.

• Highly Flammable

Highly flammable. Insoluble in water.

This material detonates at 428F or more; ignites by impact. Emits highly toxic fumes of bromides when heated to decomposition. Reacts vigorously with oxidizing materials. Becomes shock-sensitive when mixed with chloropicrin. Unstable, avoid heat, flame, shock, and other chemicals (EPA, 1998)

This material is very toxic via the oral route. If inhaled, may be harmful; contact may cause burns to skin and eyes. (EPA, 1998)

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.

Excerpt from 130 [Flammable Liquids (Water-Immiscible / Noxious)]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 50 meters (150 feet) in all directions.

LARGE SPILL: Consider initial downwind evacuation for at least 300 meters (1000 feet).

FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2020)

Wear self-contained breathing apparatus and full protective clothing. Move container from fire area if you can do it without risk. Do not get water inside container. Cool containers that are exposed to flames with water from the side until well after fire is out. Withdraw immediately in case of rising sound from venting safety device or any discoloration of tank due to fire. Isolate for 1/2 mile in all directions if tank car or truck is involved in fire.

To extinguish fire use water, foam, carbon dioxide, or dry chemical. (EPA, 1998)

Excerpt from 130 [Flammable Liquids (Water-Immiscible / Noxious)]:

ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. A vapor-suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Use clean, non-sparking tools to collect absorbed material.

LARGE SPILL: Dike far ahead of liquid spill for later disposal. Water spray may reduce vapor, but may not prevent ignition in closed spaces. (ERG, 2020)

For emergency situations, wear a positive pressure, pressure-demand, full facepiece self-contained breathing apparatus (SCBA) or pressure- demand supplied air respirator with escape SCBA and a fully-encapsulating, chemical resistant suit. (EPA, 1998)

Warning: Propargyl bromide is very toxic via the oral route, has corrosive effects, causes burns to skin and eyes, and is a strong lacrimating agent.

Signs and Symptoms of Propargyl Bromide Exposure: Signs and symptoms of acute exposure to propargyl bromide may include irritation or burning of eyes, nose, throat, respiratory tract with potential chemical pneumonitis or pulmonary edema, esophageal, GI tract, and skin irritations or burns. Kidney and hepatic injury has occurred in animals following exposure to propargyl bromide.

Emergency Life-Support Procedures: Acute exposure to propargyl bromide may require decontamination and life support for the victims. Emergency personnel should wear protective clothing appropriate to the type and degree of contamination. Air-purifying or supplied-air respiratory equipment should also be worn, as necessary. Rescue vehicles should carry supplies such as plastic sheeting and disposable plastic bags to assist in preventing spread of contamination.

Inhalation Exposure:
1. Move victims to fresh air. Emergency personnel should avoid self-exposure to propargyl bromide.
2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer 100% humidified oxygen or other respiratory support.
3. Obtain authorization and/or further instructions from the local hospital for performance of other invasive procedures.
4. Transport to a health care facility.

Dermal/Eye Exposure:
1. Remove victims from exposure. Emergency personnel should avoid self-exposure to propargyl bromide.
2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer 100% humidified oxygen or other respiratory support.
3. Remove contaminated clothing as soon as possible.
4. If eye exposure has occurred, eyes must be flushed with lukewarm water for at least 15 minutes.
5. Wash exposed skin areas three times with soap and water.
6. Obtain authorization and/or further instructions from the local hospital for performance of other invasive procedures.
7. Transport to a health care facility.

Ingestion Exposure:
1. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer 100% humidified oxygen or other respiratory support.
2. Obtain authorization and/or further instructions from the local hospital for performance of other invasive procedures.
3. DO NOT induce vomiting.
4. Activated charcoal may be administered if victims are conscious and alert. Use 15 to 30 g (1/2 to 1 oz) for children, 50 to 100 g (1-3/4 to 3-1/2 oz) for adults, with 125 to 250 mL (1/2 to 1 cup) of water.
5. Promote excretion by administering a saline cathartic or sorbitol to conscious and alert victims. Children require 15 to 30 g (1/2 to 1 oz) of cathartic; 50 to 100 g (1-3/4 to 3-1/2 oz) is recommended for adults.
6. Give the victims water or milk: children up to 1 year old, 125 mL (4 oz or 1/2 cup); children 1 to 12 years old, 200 mL (6 oz or 3/4 cup); adults, 250 mL (8 oz or 1 cup). Water or milk should not be given if victims are not conscious and alert.
7. Transport to a health care facility. (EPA, 1998)
