NFPA 704
data unavailable
General Description
Colorless to pale yellow liquid with an odor of rubbing alcohol. Floats or sinks in water. (USCG, 1999)

Hazards

The Hazard fields include special hazard alerts air and water reactions, fire hazards, health hazards, a reactivity profile, and details about reactive groups assignments and potentially incompatible absorbents. The information in CAMEO Chemicals comes from a variety of data sources.
Reactivity Alerts
none
Air & Water Reactions
No rapid reaction with air. No rapid reaction with water.
Fire Hazard
Special Hazards of Combustion Products: Irritating fumes of hydrogen chloride may form in fires.

Behavior in Fire: Solvent vapors are heavier than air and may travel to a source of ignition and flash back. (USCG, 1999)
Health Hazard
Ingestion may produce toxic effects. Contact with eyes or skin may cause severe damage. (USCG, 1999)
Reactivity Profile
HEXADECYLTRIMETHYLAMMONIUM CHLORIDE is a quaternary ammonium compound. Therefore it has a permanently charged nitrogen atom with four alkyl or aryl groups on it. Compounds in this group are generally soluble in water and are near pH 7 (neutral). They do not undergo the acid-base reactions typical of primary, secondary, or tertiary ammonium ions.

Quaternary ammonium salts often serve as catalysts in reactions. They are incompatible with many strong oxidizers and reducing agents, such as metal hydrides, alkali/active metals, and organometallics.
Belongs to the Following Reactive Group(s)
Potentially Incompatible Absorbents

Response Recommendations

The Response Recommendation fields include isolation and evacuation distances, as well as recommendations for firefighting, non-fire response, protective clothing, and first aid. The information in CAMEO Chemicals comes from a variety of data sources.
Isolation and Evacuation
Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.

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)
Firefighting
Fire Extinguishing Agents Not to Be Used: Water may be ineffective

Fire Extinguishing Agents: Dry chemical, alcohol foam, carbon dioxide (USCG, 1999)
Non-Fire Response
Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]:

Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent dust cloud. For Asbestos, avoid inhalation of dust. Cover spill with plastic sheet or tarp to minimize spreading. Do not clean up or dispose of, except under supervision of a specialist.

SMALL DRY SPILL: With clean shovel, place material into clean, dry container and cover loosely; move containers from spill area.

SMALL SPILL: Pick up with sand or other non-combustible absorbent material and place into containers for later disposal.

LARGE SPILL: Dike far ahead of liquid spill for later disposal. Cover powder spill with plastic sheet or tarp to minimize spreading. Prevent entry into waterways, sewers, basements or confined areas. (ERG, 2020)
Protective Clothing
Goggles or face shield; rubber gloves (USCG, 1999)
DuPont Tychem® Suit Fabrics
No information available.
First Aid
INGESTION: do NOT induce vomiting; drink large quanities of fluid and call a physician immediately.

EYES: flush with water for at least 15 min. and call a physician.

SKIN: flush with water. (USCG, 1999)

Physical Properties

The Physical Property fields include properties such as vapor pressure and boiling point, as well as explosive limits and toxic exposure thresholds 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.
