BECTION 7 HANDLING AND STORAGE _ Individuals with pre-existing conditions of the heart, lungs, and blood may have increased susceptibility to symptoms of asphyxia. 5. FIRST AID MEASURES (rev. 9-04) EYES In case of a burn to the eye due to combustion of natural gas, cover eyes to protect from light. Seek immediate medical attention. During cutting, annealing, or heating materials, dusts or particulates may cause mechanical irritation including pain, tearing, and redness. Scratching of the cornea can occur if eye is rubbed. Fumes may be irritating. Contact with the heated material may cause thermal burns. SKIN In case of burn due to combustion of natural gas, seek immediate medical attention. Contact with heated material or products of combustion may cause thermal burns. INGESTION Although risk of ingestion is extremely unlikely, in case of oral exposure, seek immediate medical attention. INHALATION If exposed to excessive amounts of natural gas due to a leak, remove person to fresh air using proper protective equipment. If person is not breathing, provide artificial respiration. If necessary, provide additional oxygen once breathing is restored if trained to do so. DO NOT USE ANY EQUIPMENT THAT Page 3 of 8 Revision Date: 9/24/2004 Natural Gas ID No. 1971 ERG. 115 MAY SERVE AS A SOURCE OF IGNITION UNTIL NATURAL GAS HAS COMPLETELY DISIPATED. Seek medical attention immediately. If exposed to excessive amounts of carbon monoxide due to products of incomplete combustion, remove person to fresh air using proper protective equipment. If person is not breathing, provide artificial respiration. If necessary, provide additional oxygen once breathing is restored if trained to do so. DO NOT USE ANY EQUIPMENT THAT MAY SERVE AS A SOURCE OF IGNITION UNTIL CARBON MONOXIDE HAS COMPLETELY DISIPATED. Seek medical attention immediately. 6. FIRE FIGHTING MEASURES (rev. 9-04) FLAMMABLE PROPERTIES: (NFPA Natural Gas) FLASH POINT: Flammable gas AUTOIGNITION POINT: 900 - 1170 “F (482 - 632 °C) OSHA/NFPA FLAMMABILITY CLASS: FLAMMABLE GAS LOWER EXPLOSIVE LIMIT (%): 3.8-6.5 UPPER EXPLOSIVE LIMIT (%): 13-17 FIRE AND EXPLOSION HAZARDS Dangerous fire and explosion hazard when exposed to heat, sparks or flame. Natural gas is lighter than air and may travel long distances to a point of ignition and flash back. Containers containing or which have contained natural gas may explode in heat or fire. EXTINGUISHING MEDIA To extinguish a natural gas fire, stop the flow of natural gas, use dry chemical, carbon dioxide, halon or water. Special note, the fire should not be extinguished unless flow of gas can be immediately stopped. FIRE FIGHTING INSTRUCTIONS Gas fires should not be extinguished unless flow of gas can be immediately stopped. Shut off gas source and allow gas to burn out. If spill or leak has not ignited, determine if water spray may assist in dispersing gas or vapor to protect personnel attempting to stop leak. Use water to cool equipment, surfaces and containers exposed to fire and excessive heat. For large fire the use of unmanned hose holders or monitor nozzles may be advantageous to further minimize personnel exposure. Isolate area, particularly around ends of storage vessels. Let vessel, tank car or container burn unless leak can be stopped. Withdraw immediately in the event of a rising sound from a venting safety device. Large fires typically require specially trained personnel and equipment to isolate and extinguish the fire. Firefighting activities that may result in potential exposure to high heat, smoke or toxic by-products of combustion should require NIOSH/MSHA- approved pressure-demand self-contained breathing apparatus with full face piece and full protective clothing. See Section 16 for the NFPA 704 Hazard Rating. 7. ACCIDENTAL RELEASE MEASURES (rev. 9-04) ACTIVATE FACILITY'S EMERGENCY RESPONSE PLAN. EVACUATE NONESSENTIAL PERSONNEL and secure all ignition sources. No road flares, smoking or flames in hazard area. Consider wind direction, stay upwind, if possible. Evaluate the direction of product travel. Cold vapor cloud may be white, but color will dissipate as cloud disperses - fire and explosion hazard is still present! Stop the source of the release, if safe to do so. Consider the use of water spray to disperse vapors. Isolate the area until gas has dispersed. Ventilate and gas test area before entering. Page 4 of 8 Revision Date: 9/24/2004 Natural Gas ID No. 1971 ERG. 115 8. HANDLING AND STORAGE (rev. 9-04) HANDLING and STORAGE PRECAUTIONS Keep away from flame, sparks and excessive temperatures. Store only in approved containers. These containers must meet the requirements as specified in 49 CFR 173.302. Containers should be bonded and ground when filling or discharging. Use only in well ventilated areas. See also applicable OSHA regulations for the handling and storage of this product, including, but not limited to, 29 CFR 1910.110 Storage and Handling of Liquefied Petroleum Gases. When storing natural gas, use explosion proof or intrinsically safe electrical equipment designed for the atmosphere in accordance with applicable codes, industrial recommended practices, and local, state and federal regulations. Do not smoke or use spark-producing tools in the area of use. 9. EXPOSURE CONTROLS AND PERSONAL PROTECTION (rev. 9-04) WARNING The natural gas when combusted releases products of combustion including carbon dioxide, and oxides of nitrogen. If combustion is not complete, natural gas may release carbon monoxide. Where appropriate, use carbon monoxide detectors when burning natural gas to insure that all natural gas is being combusted completely. If the carbon monoxide detector alarms, discontinue use of the appliance until a Piedmont Natural Gas employee or other authorized natural gas technician can service the appliance. ENGINEERING CONTROLS When using gas at home or in an industrial setting, use adequate ventilation to keep gas concentrations of this product below occupational exposure and flammability limits, particularly in confined spaces. When appropriate, use explosion-proof equipment and lighting in classified/controlled areas. When using natural gas, insure that natural gas concentration has not built up prior to adding ignition source. Failure to insure that natural gas concentration has not built up may result in an explosion. EYE/FACE PROTECTION When lighting natural gas, use eye protection to protect from burns. SKIN PROTECTION Where appropriate, wear proper personal protective equipment (PPE) including flame retardant clothing to protect against burns. RESPIRATORY PROTECTION Use a NIOSH/MSHA approved positive-pressure, supplied air respirator with escape bottle or self- contained breathing apparatus (SCBA) for gas concentrations above occupational exposure limits, for potential for uncontrolled release, if exposure leveis are not known, high carbon monoxide concentration, or in an oxygen-deficient atmosphere. HEARING During a high-pressure release, the release may cause a whistling noise. Hearing protection may be required for high-pressure releases of natural gas. CAUTION: Flammability limits (ie., explosion hazard) should be considered when assessing the need to expose personnel to concentrations requiring respiratory protection. Refer to OSHA 29 CFR 1910.134, ANSI Z88.2-1992, NIOSH Respirator Decision Logic, and the manufacturer for additional guidance on respiratory protection selection.

HAZARDS IDENTIFICATION (rev. 9-04) EMERGENCY OVERVIEW DANGER! EXTREMELY FLAMMABLE GAS — MAY CAUSE FLASH FIRE OR EXPLOSION!! Keep away from heat, sparks, flames, or other sources of ignition (e.g. static electricity, pilot lights, mechanical / electrical equipment) Page 1 of 9 Revision Date: 9/24/2004 Natural Gas ID No. 1971 ERG. 115 WARNING This product is a simple asphyxiant. In high concentrations it will displace oxygen from the breathing atmosphere, particularly in confined spaces. Signs of asphyxiation will be noticed when oxygen is reduced to below 16%, and may occur in several stages. Symptoms may include rapid breathing and pulse rate, headache, dizziness, visual disturbances, mental confusion, incoordination, mood changes, muscular weakness, tremors, cyanosis, narcosis and numbness of the extremities. Unconsciousness leading to central nervous system injury and possibly death will occur when the atmospheric oxygen concentration is reduced to about 6% to 8% or less. WARNING The burning of any hydrocarbon as a fuel in an area without adequate ventilation may result in hazardous levels of combustion products, including carbon monoxide, and inadequate oxygen levels, which may cause unconsciousness, suffocation, and death. 4. HEALTH HAZARDS IDENTIFICATION (rev. 9-04)

Potential health effects

Note: Natural gas in its gaseous state under normal conditions and at very low concentrations, does not present an inhalation, ingestion or skin hazard. At high concentrations, natural gas will reduce the available oxygen in the air, thus resulting in symptoms of headache, nausea, dizziness, fatigue and possibly coma and / or death. In situations where natural gas is not compietely combusted, carbon monoxide will accumulate which can cause an explosion hazard and a suffocation hazard. Special note: Using natural gas for cutting, annealing, as a chemical ingredient, or as a raw material in chemical manufacturing may cause exposure to other unknown hazards. See manufacturer of other materials for potential exposures.

Principle Routes of Exposure

Inhalation. EYES Not irritating. Under most circumstances, exposure to natural gas will not affect the eyes. Use of natural gas to heat, cut, or anneal materials should require the use of safety glasses to insure that no foreign materials enter the eye. SKIN Not irritating. When natural gas is being combusted, heat is generated which may burn the skin. Under most other circumstances, exposure to natural gas will not affect the skin. Use of natural gas to heat, cut, or anneal materials may require the use of protective clothing to insure that no parts of the body are burned or foreign materials enter the skin. INGESTION Risk of ingestion is extremely unlikely. INHALATION This product is considered to be non-toxic by inhalation. The effects of inhalation of high concentrations may cause the same effects as asphyxiation. This includes central nervous system depression such as dizziness, drowsiness, headache, and similar narcotic symptoms, but no long-term effects if removed from exposure area. Numbness, a "chilly" feeling, and vomiting have been reported from accidental exposures to high concentrations. Carbon Monoxide poisoning can occur as a result of poor installation, poor maintenance or failure or damage to an appliance in service, the fuel is not burned properly, or when rooms are poorly ventilated and the carbon monoxide is unable to escape. Carbon monoxide poisoning occurs when carbon monoxide Page 2 of 8 Revision Date: 9/24/2004 Natural Gas ID No. 1971 ERG. 115 enters the lungs via the normal breathing mechanism and displacing oxygen from the bloodstream. Interruption of the normal supply of oxygen puts at risk the functions of the heart, brain and other vital functions of the body. CHRONIC and CARCINOGENICITY Methane and ethane, the main components of natural gas, are considered practically inert in terms of physiological effects. At high concentrations these materials act as simple asphyxiants and may cause death due to lack of oxygen. Exposure to carbon monoxide concentrations can cause the following: Concentration of CO in air | Inhalation time and toxic developed 50 parts per million (ppm) Safety level as specified by the Health and Safety Executive 200 PPM Slight headache within 2-3 hours 400 PPM Frontal headache within 1-2 hours, becoming widespread in 3 hours 800 PPM Dizziness, nausea, convulsions within 45 minutes, insensible in 2 hours 1200 PPM Immediately Dangerous to Life and Health (IDLH) CARCINOGENICITY: OSHA: NO IARC: NO NTP: NO ACGIH: NO
