NFPA 704
data unavailable
General Description
A colorless odorless gas. Shipped as a liquefied gas under its own vapor pressure. Noncombustible. Heavier than air. Very toxic by inhalation. Contact with the unconfined liquid can cause frostbite. Prolonged exposure to heat can cause containers to rupture violently and rocket. Used as an insecticide fumigant in wooden structures to control termites and wood-infesting beetles, and used in organic synthesis.

Air & Water Reactions
Sulfuryl fluoride is a gas which is unaffected by water at temperatures up to 300F, but is slowly hydrolyzed by solutions of strong bases (Adv. Inorganic Chemistry, Cotton and Wilkinson, 1972, p. 455). The products of hydrolysis are hydrofluoric acid and sulfuric acid (Pesticide Profiles, Kamrin, ed., 1997, p. 548).
Fire Hazard
Excerpt from ERG Guide 123 [Gases - Toxic]:
Some may burn but none ignite readily. Vapors from liquefied gas are initially heavier than air and spread along ground. Cylinders exposed to fire may vent and release toxic and/or corrosive gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket. (ERG, 2024)

Health Hazard
Excerpt from ERG Guide 123 [Gases - Toxic]:
TOXIC; may be fatal if inhaled or absorbed through skin. Vapors may be irritating and/or corrosive. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause environmental contamination. (ERG, 2024)

Reactivity Profile
SULFURYL FLUORIDE is a gas which is unaffected by water at temperatures up to 300F, but is slowly hydrolyzed by solutions of strong bases (Adv. Inorganic Chemistry, Cotton and Wilkinson, 1972, p. 455). The products of hydrolysis are hydrofluoric acid and sulfuric acid and it is soluble in ethanol, toluene and carbon tetrachloride (Pesticide Profiles, Kamrin, ed., 1997, p. 548). It is much less reactive than sulfuryl chloride (Adv. Inorganic Chemistry, Cotton and Wilkinson, 1972, p. 455).

information in CAMEO Chemicals comes from a variety of
data sources.
Isolation and Evacuation
Excerpt from ERG Guide 123 [Gases - Toxic]:
IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 100 meters (330 feet) in all directions.
SPILL: See ERG Table 1 - Initial Isolation and Protective Action Distances on the UN/NA 2191 datasheet.
FIRE: If tank, rail tank car or highway tank 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, 2024)

Firefighting
Excerpt from ERG Guide 123 [Gases - Toxic]:
SMALL FIRE: Dry chemical or CO2.
LARGE FIRE: Water spray, fog or regular foam. Do not get water inside containers. If it can be done safely, move undamaged containers away from the area around the fire. Damaged cylinders should be handled only by specialists.
FIRE INVOLVING TANKS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Do not direct water at source of leak or safety devices; icing may occur. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks in direct contact with flames. (ERG, 2024)

Non-Fire Response
Excerpt from ERG Guide 123 [Gases - Toxic]:
Do not touch or walk through spilled material. Stop leak if you can do it without risk. If possible, turn leaking containers so that gas escapes rather than liquid. Prevent entry into waterways, sewers, basements or confined areas. Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material. Do not direct water at spill or source of leak. Isolate area until gas has dispersed. (ERG, 2024)

Protective Clothing
Excerpt from NIOSH Pocket Guide for Sulfuryl fluoride:
Skin: FROSTBITE - Compressed gases may create low temperatures when they expand rapidly. Leaks and uses that allow rapid expansion may cause a frostbite hazard. Wear appropriate personal protective clothing to prevent the skin from becoming frozen.
Eyes: FROSTBITE - Wear appropriate eye protection to prevent eye contact with the liquid that could result in burns or tissue damage from frostbite.
Wash skin: No recommendation is made specifying the need for washing the substance from the skin (either immediately or at the end of the work shift).
Remove: No recommendation is made specifying the need for removing clothing that becomes wet or contaminated.
Change: No recommendation is made specifying the need for the worker to change clothing after the workshift.
Provide: FROSTBITE WASH - Quick drench facilities and/or eyewash fountains should be provided within the immediate work area for emergency use where there is any possibility of exposure to liquids that are extremely cold or rapidly evaporating. (NIOSH, 2024)

First Aid
Excerpt from NIOSH Pocket Guide for Sulfuryl fluoride:
Eye: FROSTBITE - If eye tissue is frozen, seek medical attention immediately; if tissue is not frozen, immediately and thoroughly flush the eyes with large amounts of water for at least 15 minutes, occasionally lifting the lower and upper eyelids. If irritation, pain, swelling, lacrimation, or photophobia persist, get medical attention as soon as possible.
Skin: FROSTBITE - If frostbite has occurred, seek medical attention immediately; do NOT rub the affected areas or flush them with water. In order to prevent further tissue damage, do NOT attempt to remove frozen clothing from frostbitten areas. If frostbite has NOT occurred, immediately and thoroughly wash contaminated skin with soap and water.
Breathing: RESPIRATORY SUPPORT - If a person breathes large amounts of this chemical, move the exposed person to fresh air at once. If breathing has stopped, perform artificial respiration. Keep the affected person warm and at rest. Get medical attention as soon as possible. (NIOSH, 2024)

The information in CAMEO Chemicals comes from a variety of
data sources.
Note: For Vapor Density and Specific Gravity, comparing the value to 1.0 can tell you if the chemical will likely sink/rise in air or sink/float in fresh water (respectively). Short phrases have been added to those values below as an aid. However, make sure to also consider the circumstances of a release. The Vapor Density comparisons are only valid when the gas escaping is at the same temperature as the surrounding air itself. If the chemical is escaping from a container where it was pressurized or refrigerated, it may first escape and behave as a heavy gas and sink in the air (even if it has a Vapor Density value less than 1). Also, the Specific Gravity comparisons are for fresh water (density 1.0 g/mL). If your spill is in salt water (density about 1.027 g/mL), you need to adjust the point of comparison. There are some chemicals that will sink in fresh water and float in salt water.
