EMERGENCY OVERVIEW: This is a colorless to red-brown, non-flammable gas mixture with an acidic odor.Inhalation of this gas mixture can cause serious health effects and may be fatal. Symptoms of overexposure may not become apparent for up to 72 hours. This gas mixture may cause severe irritation and burns to skin, eyes, and other contaminated tissue. This gas mixture is not flammable. Additionally, releases of this gas mixture may produce oxygen-deficient atmospheres. Individuals in such atmospheres may be asphyxiated. Emergency
Responders must protect themselves from inhalation exposures.
ROUTES OF ENTRY, SYMPTOMS OF ACUTE EXPOSURE: WARNING - If rescue personnel need to enter an area suspected of having a toxic level of Nitrogen Dioxide, they should be equipped with Self-Contained Breathing Apparatus (SCBA), and, if available, a full-body chemically resistant suit. Acute overexposure to this gas mixture may cause the following health effects:
EYE CONTACT: If this gas mixture contaminates the eyes, severe injury and swelling of the eye tissue may occur.
INGESTION: Ingestion of this gas mixture is not a likely route of industrial exposure.
SKIN CONTACT: Prolonged exposure may cause potentially harmful amounts of Nitrogen Dioxide, a component of this gas mixture, to enter the body via absorption through the skin. This gas mixture may be irritating to exposed skin, especially in a moist environment. Symptoms of skin overexposure may include scratchiness, pain, and redness.
INHALATION: Inhalation of Nitrogen Dioxide, a component of this gas mixture, in low concentrations produces an irritating effect on the mucous membranes of the eyes, nose, throat, and lungs. Symptoms may include dryness and irritation of the nose and throat, choking, coughing, and bronchospasm.Severe overexposure may cause death through systemic, delayed pulmonary edema. Exposure to high concentrations may also cause unconsciousness, and under some circumstances, death. Medical care after overexposure is essential, as symptoms will rapidly worsen, possibly leading to death. Repeated overexposures to Nitrogen Dioxide can cause dental erosion and gum disorders. Typical symptoms of overexposure are:
|Concentration of Nitrogen Dioxide||Exposure Symptom|
|25 ppm||Delayed (5-72 hours) pulmonary irritation after 8 hours exposure.|
|100-150 ppm||Delayed (5-48 hours) pulmonary edema after exposure for 30-60 minutes.|
|200-700 ppm||Delayed (5-8 hours) severe pulmonary damage after only a few breaths.|
High concentrations of this gas mixture can cause an oxygen-deficient environment. Individuals breathing such an atmosphere may experience symptoms which include headaches, ringing in ears, dizziness,drowsiness,unconsciousness, nausea, vomiting, and depression of all the senses. Under some
circumstances of overexposure, death may occur It should be noted that before adverse health effects or suffocation could occur the effects of overexposure to Nitrogen Dioxide will be felt.

MEDICAL CONDITIONS AGGRAVATED BY OVEREXPOSURE: Pre-existing respiratory, dental, skin, and eye conditions may be aggravated by overexposure to this gas mixture.
CARCINOGENICITY: Nitrogen Dioxide, a component of this gas mixture, is listed as follows: ACGIH-A4 (Not Classifiable as a Human Carcinogen). Nitrogen Dioxide and Nitrogen are not found on the FEDERAL OSHA Z LIST, NTP, or CAL/OSHA, Carcinogenicity lists and therefore are neither considered to be nor suspected to be cancercausing agents by these agencies.
EYE CONTACT: If irritation of the eye develops after exposure to this gas mixture, open victim's eyes while under gentle, lukewarm, running water. Use sufficient force to open eyelids. Have victim "roll" eyes. Minimum flushing is
for 15 minutes. Victim must seek immediate medical attention from an ophthalmologist.
INGESTION: Ingestion is an unlikely route of exposure for this gas.
INHALATION: Remove victim(s) to fresh air, as quickly as possible. Trained personnel should administer supplemental oxygen and/or cardio-pulmonary resuscitation, if necessary. Victim must seek immediate medical attention.
SKIN CONTACT: If irritation of the skin develops after exposure to gas mixture, immediately begin decontamination with running water. Minimum flushing is for 15 minutes. Remove exposed or contaminated clothing, taking care not to contaminate eyes.
NOTES TO PHYSICIANS: Administer oxygen as soon as possible following exposure. Due to the presence of Nitrogen Dioxide in this gas mixture, be observant for signs of pulmonary edema. If possible, have victim breathe as deeply and rapidly as possible to help flush gas from the lungs. Enforce bed rest for 24 - 48 hours, whether or not symptoms have appeared. Start oxygen therapy at the first sign of symptoms. Provide medication to reduce anxiety and dyspnea, as needed. Keep respiratory tract clear of mucous and exudate. Atropine, epinephrine, expectorants, emetics, most sedatives, and most cardiac glycosides are usually ineffective and possibly harmful. Surgical intervention to assist breathing may be necessary. Respiratory infection should be controlled as soon as it is detected. Prednisone has been reported to be effective during recovery, in amounts of 3-8 x 10-6 kg daily, in divided doses. If this gas mixture contaminates the eye, use an optic anesthetic to reduce pain. The victim should be promptly examined by an ophthalmologist.

REACTIVITY: = 0 SPECIAL: None
EXTINGUISHING MEDIA: This is a non-flammable gas mixture; use fireextinguishing
media appropriate for the surrounding materials.
SPECIAL FIRE-FIGHTING PROCEDURES: Evacuate all personnel from area. If
possible without risk, shut off source of gas, then fight fire according to types of materials burning. If cylinder is not actively a part of the fire, remove from fire area. If this is not possible, cool cylinder with a water spray to prevent violent rupture. Fire fighters must wear Self-Contained Breathing Apparatus and full protective equipment. If this product is involved in a fire, fire run-off water should be contained to prevent possible environmental damage. If necessary, decontaminate fire-response equipment with soap and water solution.
UNUSUAL FIRE AND EXPLOSION HAZARDS: This gas mixture presents a significant inhalation hazard to firefighters, due to the presence of Nitrogen Dioxide. Water spray should be used with care. Nitrogen Dioxide can slowly react with water to form a corrosive solution of nitric acid. Nitric acid is corrosive to skin and metal. Corrosive and toxic gases, vapors, and mists may spread from the point of release. This gas mixture does not burn; however, containers, when involved in fire, may rupture or burst in the heat of the fire.
EXPLOSION SENSITIVITY TO MECHANICAL IMPACT: Not sensitive.
EXPLOSION SENSITIVITY TO STATIC DISCHARGE: Not sensitive.
HAZARDOUS COMBUSTION PRODUCTS: Not applicable.
STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED: In the event of a leak of this product, operator should close the gas source if possible to do so safely. Evacuate immediate area. Only trained personnel, wearing Self-Contained Breathing Apparatus (SCBA) and a chemically resistant suit should re-enter a contaminated area. If leak is in user’s gas handling equipment or system, close cylinder valve, safely vent high pressure and purge with inert gas, being sure to bring purge gas to near atmospheric pressure before attempting repairs. If leak is from the cylinder, cylinder valve or the valve pressure relief device (PRD), contact your supplier.
Levels of Nitrogen Dioxide should be below applicable exposure levels listed in Section 2 (Composition / Information on Ingredients) before personnel can be allowed in the area without SCBA.
Detection systems should be available to monitor for leaks and to measure the level of Nitrogen Dioxide.
STORAGE: Cylinders should be stored upright (with valve protection caps or plugs in place) and firmly secured to prevent falling or being knocked over. Cylinders should be stored in dry, well-ventilated areas. Protect from salt or
other corrosive materials. Storage should be away from heavily traveled areas, walkways, elevators, platform edges or other objects or situations that could damage the cylinder wall. Do not store in a manner that will block emergency exits, fire extinguishers or other safety equipment. Do not allow storage temperature to exceed 125°F (52°C). Use a first-in, first-out inventory system to prevent full containers from being stored for long periods of time.
Store empty cylinders away from full cylinders. Consideration should be taken to install leak detection and alarm equipment for storage areas. NOTE: Use only DOT or ASME code cylinders designed for compressed gas storage. Cylinders must not be recharged except by or with the consent of owner.
HANDLING: This mixture can be dangerous and should only be handled by trained personnel. Wearing contact lenses is not recommended when handling this gas mixture. Spectra Gases, Inc., strongly recommends that this gas mixture only be handled in areas with extensive venting capabilities, preferably a gas handling cabinet.
Before using this gas, meticulous leak checking using inert gas is strongly recommended, particularly after new connections are made. Cylinder valves should be inspected regularly for physical damage or corrosion(apparent by discoloration or rust). Care should be taken to inspect the following valve locations for corrosion: neck(where valve inserts into cylinder); bonnet nut (where handle attaches to valve body). Close valve after each use and when empty.
Nitrogen Dioxide detectors are strongly recommended. Do not drag, roll, slide or drop cylinder. Use a suitable hand truck designed for cylinder movement. Never attempt to lift a cylinder by its cap. Secure cylinders at all times while in use. Use a separate pressure regulator to safely discharge product from cylinder. Use a check valve to prevent reverse flow into cylinder. Once cylinder has been connected to properly purged process, open cylinder valve slowly and carefully. If user experiences any difficulty operating cylinder valve, discontinue use and contact supplier. Never insert an object (e.g., wrench, screwdriver, etc.) into valve cap openings; doing so may damage valve, causing a leak to occur. Use an adjustable strap-wrench to remove over-tight or rusted caps.
Do not heat cylinders by any means to increase the discharge rate of product from the cylinder. Never apply flame or localized heat directly to any part of the cylinder. Cylinders should not be artificially cooled as certain types of
steel undergo property changes when cryogenically cooled, thus making the cylinder unstable.
PROTECTIVE PRACTICES DURING MAINTENANCE OF CONTAMINATED EQUIPMENT: Follow practices indicated in Section 6 (Accidental Release Measures). Purge gas handling equipment with inert gas and relieve pressure before attempting repairs.
SPECIAL PRECAUTIONS: Be aware of any signs of dizziness or fatigue; exposures to fatal concentrations of this gas mixture could occur without any significant warning symptoms. All work operations should be monitored in such a way that emergency personnel can be immediately contacted in the event of a release. Local regulations may require specific equipment for storage and use.
VENTILATION AND ENGINEERING CONTROLS: Forced ventilation systems for the general work area should be provided. Spectra Gases, Inc. recommends that cylinders in use be secured within a ventilated enclosure such as a gas cabinet. Employee exposure should be monitored and reduced to the lowest practical levels using ventilation or other appropriate engineering controls. If appropriate, install automatic monitoring equipment to detect the level of
RESPIRATORY PROTECTION: Maintain exposure levels of Nitrogen Dioxide below the levels listed in Section 2 (Composition / Information on Ingredients) and oxygen levels above 19.5% in the workplace. Use supplied air respiratory protection if Nitrogen Dioxide levels exceed exposure limits, if oxygen level is below 19.5%, or during emergency response to a release of this product.The following NIOSH respiratory protection recommendations are for Nitrogen Dioxide.
