SECTION 4: First aid measures
Description of necessary first-aid measures
Fresh air, rest.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention .
Most important symptoms/effects, acute and delayed
Pyrene is a carcinogenic agent and is absorbed by the skin. It is a skin irritant, a suspected mutagen, and an equivocal tumor-causing agent. Workers exposed to 3 to 5 mg/m3 of pyrene exhibited some teratogenic effects. Pyrene is a polycyclic aromatic hydrocarbon (PAH). The acute toxicity of pure PAHs appears low when administered orally or dermally to rats or mice. Human exposure to PAHs is almost exclusively via the gastrointestinal and respiratory tracts, and approximately 99 percent is ingested in the diet. Despite the high concentrations of pyrene to which humans may be exposed through food, there is currently little information available to implicate diet-derived PAHs as the cause of serious health effects. (EPA, 1998)
Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Aromatic hydrocarbons and related compounds
SECTION 5: Firefighting measures
Suitable extinguishing media
This chemical is a combustible solid. Use dry chemical, carbon dioxide, water spray, or alcohol foam extinguishers. Poisonous gases are produced in fire. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Notify local health and fire officials and pollution control agencies. From a secure, explosion-proof location, use water spray to cool exposed containers. If cooling streams are ineffective (venting sound increases in volume and pitch, tank discolors, or shows any signs of deforming), withdraw immediately to a secure position.
Specific hazards arising from the chemical
When heated to decomposition, it emits acrid smoke and fumes. (EPA, 1998)
Special protective actions for fire-fighters
Use water spray, carbon dioxide, dry powder, alcohol-resistant foam, polymer foam.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder.
Environmental precautions
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder.
Methods and materials for containment and cleaning up
SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.
SECTION 7: Handling and storage
Precautions for safe handling
NO open flames, NO sparks and NO smoking. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Bioaccumulative potential
Experimental BCF values of 72(1), 457(2), and 600-970(3) have been reported in rainbow trout, goldfish and fathead minnow respectively. According to a classification scheme(4), these BCF values suggest that bioconcentration in aquatic organisms is moderate to high(SRC). Pyrene was shown to bioaccumulate in worms exposed to contaminated sediment over a 4 week incubation period, reaching a maximum concn of 60.9 ng/g and an uptake rate constant of 0.0256 hr-L(5). Pyrene had biota-sediment accumulation factors of 0.76 and 0.92 in Elliptio complanata and Mya arenaria(6). BCFs for pyrene in the amphipod Diporeia spp were measured as 36,329, 30,671, 16,810 and 12,316 calculated from the time-weighted avg water concns of 34.0, 51.3, 84.5 and 130.7 ug/L, respectively(7).
Mobility in soil
Experimental Koc values determined with 5 sediment samples obtained from a freshwater lake in Louisiana were 64,954, 63,372, 73,127, 65,380 and 59,675(1). The Koc values of pyrene obtained with soil samples from Flint, MI and Bordone, Canada were 61,936 and 90,000 respectively(2). Measured Koc values of 160,000, 153,000, 98,700 and 169,000 were obtained for pyrene with suspended solids and sediment from the Boston Harbor, MA(3). An experimental Koc value of 76,000 was reported for pyrene with soil obtained from a water treatment facility in Sweden(4). Experimentally determined log Koc values between 4.9 and 5.4 were reported for pyrene with sediment obtained from Lake Michigan(5) and a log Koc value of 5.5 was reported with sediment obtained from the Boston Harbor, MA(6). Pyrene had a log Koc in sediment from Lake Ketelmeer, The Netherlands of 6.80 (3.75% organic carbon, 0-30 cm depth) and 5.95 (6.48% organic carbon, 40-120 cm depth)(7). Boston Harbor, MA sediment samples taken from South Dorchester Bay, North Quincy, Fort Point Channel and Spectacle Island had log Koc values of 3.54, 3.71, 4.32 and 4.55, respectively, in samples taken Dec 1999(9). According to a classification scheme(10), these Koc values suggest that pyrene is expected be immobile in soil.
Other adverse effects

SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.

Other Information
Pyrene is one of many polycyclic aromatic hydrocarbons - standards are usually established for them as mixtures, e.g., coal tar pitch volatiles.However, pyrene may be encountered as a laboratory chemical in its pure form.Health effects of exposure to the substance have not been investigated adequately.See ICSC 1415.
