Section 1 : PRODUCT AND COMPANY IDENTIFICATION Product name: Nitrogen (Gaseous), Supplier/ Manufacturer: Universal Industrial Gases, Inc. 2200 Northwood Avenue, Suite 3 Easton, PA 18045-2239 USA (610) 559-7967. Emergency phone: (610) 559-7967.

Section 2 : COMPOSITION/ INGREDIENT INFORMATION C.A.S. CONCENTRATION % Ingredient Name OSHA PEL ACGIH TLV OSHA STEL 7727-37-9 > 99 NITROGEN   NONE SIMPLE ASPHYXIANT NONE

Section 3 : HAZARD IDENTIFICATION Emergency Overview: Nitrogen gas is colorless, odorless and non-flammable. It is non-toxic.  The primary health hazard is asphyxiation by displacement of oxygen.  Route of entry: Inhalation, skin and eye contact. Effects of acute exposure   Eye contact: Vapor may cause a stinging sensation. Skin contact: No adverse effects from gas. Inhalation: May cause dizziness. Asphyxiant. Can cause vomiting. May result in unconsciousness. May cause excitation, excess salivation, rapid breathing. May cause headaches and drowsiness. May cause stinging of the nose and throat. Ingestion: Not a likely route of exposure. Effects of chronic exposure: None known.  Chronic exposure to abnormal concentrations unlikely Reproductive effects: Oxygen deficiency during pregnancy has produced developmental abnormalities in humans and experimental animals.

Section 4 : FIRST AID MEASURES Skin contact: None required. Eye contact: None required. Inhalation: RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE TO THIS PRODUCT WITHOUT ADEQUATE PERSONAL PROTECTIVE EQUIPMENT. At a minimum, Self-Contained Breathing Apparatus should be worn. Remove victim(s) to fresh air, as quickly as possible. If not breathing qualified personnel should administer artificial respiration. Get medical attention. If breathing is difficult, administer oxygen. Ingestion: No first aid should be needed. Not considered a potential route of exposure.

Section 5 : FIRE FIGHTING MEASURES Flammability: Not flammable. Conditions of flammability: Will not burn. Extinguishing media: Use appropriate extinguishing media for surrounding fire. Special procedures: Self-contained breathing apparatus required. Firefighters should wear the usual protective gear. Cool fire exposed containers with water spray. Personnel should be evacuated, if necessary, to upwind area. Remove containers from fire area if without risk. Auto-ignition temperature: Not applicable. Flash point (°C), method: Not applicable. Lower flammability limit (% vol): Not applicable. Upper flammability limit (% vol): Not applicable. Explosion Data   Sensitivity to mechanical impact: Avoid impact against container. Explosive power: Closed containers may rupture or explode due to pressure build-up when exposed to extreme heat. Cylinders are equipped with temperature and pressure relief devices but may still rupture under fire conditions.

Section 6 : ACCIDENTAL RELEASE MEASURES Leak/Spill: Evacuate all non-essential personnel. Stop leak without risk. Wear gloves and goggles Use a self-contained breathing apparatus.   Ventilate area. Monitor the surrounding area for Oxygen level. Oxygen must be at least 19.5% before personnel may be allowed into the area without self-contained breathing apparatus.   If the area must be entered by emergency personnel, self-contained breathing apparatus, Kevlar gloves, and appropriate foot and leg protection must be worn.

Section 7 : HANDLING AND STORAGE Handling procedures and equipment: Protect system components against physical damage. Use adequate ventilation. Avoid inhalation. Never work on a pressurized system. If there is a leak, close the upstream valve, blow down the system by venting to a safe place, then repair the leak. Storage requirements: Use storage containers, piping, valves and fittings designed for storage and distribution of Gaseous Nitrogen. Protect cylinders against physical damage. Store in cool, dry, well-ventilated, fireproof area, away from flammable materials and corrosive atmospheres. Store away from heat and ignition sources and out of direct sunlight. Do not store near elevators, corridors or loading docks. Do not allow area where cylinders are stored to exceed 52°C (125°F). Move cylinders with a suitable hand-truck. Do not drag, slide or roll cylinders. Do not drop cylinders or permit them to strike each other. Secure cylinders firmly. Leave the valve protection cap in-place (where provided) until cylinder is placed into service and after it is taken out of service. Use designated CGA fittings and other support equipment. Do not use adapters. Do not heat cylinder by any means to increase the discharge rate of the product from the cylinder. Use check valve or trap in discharge line to prevent hazardous backflow into the cylinder. Do not use oils or grease on gas-handling fittings or equipment. After use, close main cylinder valve. Replace valve protection cap (where provided). Mark empty cylinders "EMPTY".

Section 8 : EXPOSURE CONTROLS / PERSONAL PROTECTION Precautionary Measures   Gloves/Type: Work gloves Respiratory/Type: NIOSH/MSHA approved respirator. Eye/Type: As per local regulations. Footwear/Type: Safety boots per local regulations. Clothing/Type: Wear adequate protective clothes. Other/Type: Eye wash facility should be in close proximity. Emergency shower should be in close proximity. Ventilation requirements: Mechanical ventilation is satisfactory. Ensure oxygen concentration remains above 19.5% and Carbon Dioxide concentration does not exceed 5000 ppm, Local exhaust at points of emission preferred. Exposure limit of material Simple asphyxiant.

Definitions and other useful data: CAS #: The Chemical Abstract Service Number which uniquely identifies each constituent. ACGIH - American Conference of Governmental Industrial Hygienists, a professional association which establishes exposure limits. TLV - Threshold Limit Value - an airborne concentration of a substance which represents conditions under which it is generally believed that nearly all workers may be repeatedly exposed without adverse effect. OSHA - U.S. Occupational Safety and Health Administration. PEL - Permissible Exposure Limit - The same value as a TLV, except it is enforceable by OSHA.
