Air and Water Reactions

fire hazard
Specific Hazards From Combustion Products: Exposure to fire may produce irritating fumes and toxic gases such as carbon dioxide and carbon monoxide. (USCG, 1999)
health hazard
Corrosive. Very harmful to mucosal tissues, upper respiratory tract, eyes and skin. Symptoms may include burning, coughing, wheezing, laryngitis, shortness of breath, nausea, and vomiting. Extremely harmful to the skin. It can be absorbed through the skin. (USCG, 1999)
reactivity profile
PENTANOIC ACID is a carboxylic acid. It exothermically neutralizes both organic and inorganic bases, producing water and a salt. Can react with active metals to form hydrogen gas and a metal salt. Reacts with cyanide salts to form gaseous hydrogen cyanide. Flammable and/or toxic gases and heat are generated by reaction with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides and sulfides. Reacts with sulphites, nitrites, thiosulphates and dithionites releasing flammable and/or toxic gases and heat. Reacts with carbonates and bicarbonates to form a harmless gas (carbon dioxide) but still heat. It can be oxidized by strong oxidizing agents and reduced by strong reducing agents. These reactions generate heat. Can initiate polymerization reactions. It can catalyze (increase the speed of) chemical reactions.
Belongs to the following reactive group(s)
- carboxylic acids
Potentially incompatible absorbents

Response recommendations
What is this information?
ÖResponse recommendation fieldsinclude isolation and evacuation distances, firefighting recommendations, non-firefighting procedures, protective clothing and first aid. CAMEO Chemicals information comes from a variety of sourcesdata sources.
isolation and evacuation
Extract fromGuia ERG 153[Substances - Toxic and/or Corrosive (Fuel)]:
IMMEDIATE PRECAUTIONS: Isolate the spill or leak area in all directions at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.
BURIAL: Increase distance of immediate upwind precaution if necessary.
FIRE: If a tank, wagon or truck is involved in a fire, ISOLATE 800 meters (1/2 mile) in all directions; Also consider the initial evacuation of 800 meters (1/2 mile) in all directions. (ERG, 2020)
fight fire
Extract fromGuia ERG 153[Substances - Toxic and/or Corrosive (Fuel)]:
SMALL FIRE: Dry chemical, CO2 or water spray.
LARGE FIRE: Dry chemical, CO2, alcohol-resistant foam, or water spray. If safe to do so, remove undamaged containers from fire area. Fire protection dike drain for later disposal.
TANK OR VEHICLE/TRAILER LOADS FIRE: Fight fire from maximum distance or use unmanned Master Flow devices or surveillance nozzles. Do not fill the containers with water. Keep containers holding large volumes of water cool until well after fire is out. Remove immediately if there is increased noise from vent fuses or tank discoloration. ALWAYS stay away from burning tanks. (ERG, 2020)
No fire reaction
Extract fromGuia ERG 153[Substances - Toxic and/or Corrosive (Fuel)]:
ELIMINATE all sources of ignition (no smoking, flames, sparks or flames) in the immediate area. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop the leak if it's safe to do so. Prevent entry into waterways, sewers, basements or confined areas. Soak up or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT PUT WATER INTO CONTAINERS. (ERG, 2020)
protective clothing
Fully waterproof protective clothing including boots and gloves. Where splashing is possible, wear full face shield or chemical goggles. Do not wear contact lenses when working with this material. Use approved respirator to protect against fumes. (USCG, 1999)

Testdetails
Permeability data was generated for DuPont by a third party laboratory. Industrial chemical permeation data is obtained in accordance with ASTM F739. Normalized breakthrough times (the time for the permeation rate to exceed 0.1 µg/cm2/min) are given in minutes. All chemicals were tested between approximately 20°C and 27°C unless otherwise noted. All chemicals tested at greater than 95% concentration unless otherwise noted. Chemical warfare agents (Lewisite, Sarin, Soman, Sulfur Mustard, Tabun, and VX Nerve Agent) were tested at 22°C and 50% relative humidity per military standard MIL-STD-282. The "breakthrough time" for chemical warfare agents is defined as the time at which the cumulative mass that has penetrated the tissue exceeds the limit in MIL-STD-282 [1.25 or 4.0 μg/cm2].
A DuPont warning
This information is based on technical data that DuPont believes to be reliable at the time of publication. It may be revised as additional knowledge and experience is gained. The information reflects the laboratory performance of fabrics, not complete garments, under controlled conditions. It is intended for informational use by persons technically capable of evaluating it under its specific end-use conditions at their own risk and expense. It is the user's responsibility to determine the level of toxicity and the appropriate personal protective equipment required. Anyone wishing to use this information must first ensure that the clothing selected is suitable for its intended use. In many cases, seams and fasteners have shorter break times and higher permeation rates than woven fabrics. If the fabric is torn, frayed or punctured, or if seams or fasteners fail, or if attached gloves, visors, etc. are damaged, the end user must stop using the garment to avoid potential chemical exposure. Because the Terms of Use are beyond our control, DuPont makes no warranties, express or implied, including but not limited to the warranties of merchantability or fitness for a particular use, and assumes no liability in connection with the use of this information. This information is not intended as a license to operate or a recommendation to infringe any patent, trademark, or technical information of DuPont or others relating to the Materials or their use.

More information...
...Tychem® ThermoPro, Tychem® Reflector® and Tychem® TK types 600T/601T (with aluminised outer shell) have been developed and tested to reduce burn injuries while escaping a stick fire. Users of Tychem® ThermoPro, Tychem® Reflector® and Tychem® TK Styles 600T/601T (with aluminized outerwear) should not intentionally enter a potentially explosive atmosphere. Tychem® garments with attached socks must be worn in protective outdoor footwear and are not suitable as outdoor footwear. These attached socks do not have sufficient durability or slip resistance to be used as outer foot covering.

First aid
EYES: First check the victim for contact lenses and remove if present. Flush the victim's eyes with water or normal saline for 20 to 30 minutes while calling a hospital or poison control center. Do not put any ointment, oil, or medication in the victim's eyes without the specific direction of a doctor. Transport the victim to a hospital IMMEDIATELY after washing the eyes, even if there are no symptoms (such as redness or irritation).
SKIN: Flush affected skin IMMEDIATELY with water while removing and quarantining all contaminated clothing. Wash all affected skin thoroughly with soap and water. Call a hospital or poison control center IMMEDIATELY even if there are no symptoms (such as redness or irritation). IMMEDIATELY transport the injured person to a hospital for treatment after washing the affected areas.
INHALATION: IMMEDIATELY leave contaminated area; take a deep breath of fresh air. If symptoms develop (such as wheezing, coughing, shortness of breath, or a burning sensation in the mouth, throat, or chest), call a doctor and prepare to take the victim to a hospital. Provide emergency responders with appropriate respiratory protection when entering an unfamiliar atmosphere. If possible, use self-contained breathing apparatus (SCBA); If not available, use a level of protection greater than or equal to that recommended in protective clothing.
INGESTION: DO NOT INDUCE VOMITING. Harsh chemicals destroy the mucous membranes of the mouth, throat and esophagus, and also pose a high risk of being inhaled into the victim's lungs when vomiting, increasing medical problems. If victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute chemical and call a hospital or poison control center IMMEDIATELY. Transport the injured person to a hospital IMMEDIATELY. If the victim is convulsing or unconscious, do not give anything by mouth, make sure the victim's airway is patent, and lay the victim on their side with the head lower than the body. DO NOT INDUCE VOMITING. Transport the victim to a hospital IMMEDIATELY. (NTP, 1992)
