Hydrocarbons, Aliphatic Saturated

Saturated aliphatic hydrocarbons, such as N-HEXACOSANE, may be incompatible with strong oxidizing agents like nitric acid. Charring of the hydrocarbon may occur followed by ignition of unreacted hydrocarbon and other nearby combustibles. In other settings, aliphatic saturated hydrocarbons are mostly unreactive. They are not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents. When heated sufficiently or when ignited in the presence of air, oxygen or strong oxidizing agents, they burn exothermically to produce carbon dioxide and water.

SRP: Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in air, soil or water; effects on animal, aquatic and plant life; and conformance with environmental and public health regulations. If it is possible or reasonable use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination.|Product: Offer surplus and non-recyclable solutions to a licensed disposal company; Contaminated packaging: Dispose of as unused product.

Incompatible materials: Strong oxidizing agents.

Flash point data on this compound is not available, but it is probably combustible. (NTP, 1992)

SMALL SPILLS AND LEAKAGE: 1. STORAGE PRECAUTIONS: You should store this material in a refrigerator. (NTP, 1992)

RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. RECOMMENDED GLOVE MATERIALS: Permeation data indicate that butyl rubber gloves may provide protection to contact with this compound. Butyl rubber over latex gloves is recommended. However, if this chemical makes direct contact with your gloves, or if a tear, hole or puncture develops, remove them at once. (NTP, 1992)|Eye/face protection: Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).|Skin protection: Handle with gloves.|Body Protection: Choose body protection in relation to its type, to the concentration and amount of dangerous substances, and to the specific work-place.|Respiratory protection: Respiratory protection is not required. Where protection from nuisance levels of dusts are desired, use type N95 (US) or type P1 (EN 143) dust masks. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).

Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.|Advice for firefighters: Wear self contained breathing apparatus for fire fighting if necessary.

ACCIDENTAL RELEASE MEASURES: Personal precautions, protective equipment and emergency procedures: Avoid dust formation. Avoid breathing vapors, mist or gas. Environmental precautions: Do not let product enter drains. Methods and materials for containment and cleaning up: Sweep up and shovel. Keep in suitable, closed containers for disposal.

ACCIDENTAL RELEASE MEASURES: Personal precautions, protective equipment and emergency procedures: Avoid dust formation. Avoid breathing vapors, mist or gas. Environmental precautions: Do not let product enter drains.|Precautions for safe handling: Provide appropriate exhaust ventilation at places where dust is formed. Normal measures for preventive fire protection.|Appropriate engineering controls: General industrial hygiene practice.|Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands.|For more Preventive Measures (Complete) data for n-Hexacosane (6 total), please visit the HSDB record page.

/Higher alkanes/ may cause eye and skin irritation.

Alkanes (C20-C32) were the most abundant trace organic compounds found in particulate matter from vehicle exhaust with emission factors for hexacosane from diesel driven light-duty vehicles of 3.42-78.2 ug/km(1).

SEDIMENT: Hexacosane concentrations were 0.7-133 ng/g dry weight in sediments samples collected from 14 sites from the Shinano River in Niigata, Japan from November 2005 to April 2006(1).

URBAN/SUBURBAN: Hexacosane was detected in particulate air samples from Georgia Tech campus, GA at mean concentrations of 1.15 and 2.33 ng/cu m for summer 2005 and winter 2006, respectively(1). A mean hexacosane concentration of approximately 18 ng/cu m was reported in the particulate phase of air samples collected in an urban and industrialized area in Prato, Italy during 2002(2). Hexacosane concentration was 8.2 and 8.7 ng/cu m in particulate phase in the summer and winter, respectively; the concentration was 5.6 and 0.9 ng/cu m in the vapor phase in summer and winter, respectively; samples were collected in an urban area in Nagoya, Japan in 1991(3).|RURAL/REMOTE: Hexacosane was detected in particulate air samples from a rural area of Yorkville, GA at mean concentrations of 0.29 and 1.74 ng/cu m for summer and winter, respectively(1).|SOURCE DOMINATED: Hexacosane was detected in the gas and particle phase of tailpipe emissions from non-catalyst equipped gasoline powered motor vehicles at concentrations of 9.6 and 764 ug/km, respectively(1). Hexacosane was detected at 61-650 pg/cu m with a mean of 220 pg/cu m in particulate air samples collected near a highway in Raleigh, NC; concentrations in samples collected 275 meters from the highway contained 70-740 pg/cu m with a mean of 190 pg/cu m(2). Hexacosane was detected in particulate air samples from an interstate highway in Georgia at a mean concentration of 1.93 and 4.00 ng/cu m for summer and winter, respectively(3).
