NITROGEN

CAS: 7727-37-9

RTECS: QW9700000

Fraction By Weight: 100%

ACGIH TLV: ASPHYXIANT; 9192

LD50 LC50 Mixture:NOT SPECIFIED BY MANUFACTURER.
Routes of Entry: Inhalation:YES Skin:NO Ingestion:NO
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:NITROGEN IS DEFINED AS A SIMPLE
ASPHYXIANT. NITROGEN IS NON-TOXIC BUT THE LIBERATION OF LARGE
AMOUNTS IN A CONFINED AREA COULD DISPLACE THE AMOUNT OF OXYGEN IN
AIR NECESSARY TO SUPPORT LIFE. OXYGEN LE VELS SHOULD BE MAINTAINED
AT >18 MOLAR PERCENT AT NORMAL ATMOSPHERIC PRESSURE WHICH IS
EQUIVALENT TO 135 MM HG PART.PRES
Explanation of Carcinogenicity:NITROGEN IS NOT CLASSIFIED AS A
CARCINOGEN BY NTP, IARC OR OSHA.
Effects of Overexposure:EFFECTS OF EXPOSURE TO HIGH CONCENTRATIONS
WHICH DISPLACE OXYGEN IN AIR MAY INCLUDE: LOSS OF BALANCE,
DIZZINESS, TIGHTNESS IN THE FRONTAL AREA OF FOREHEAD, TINGLING OF
TONGUE/FINGERTIPS/TOES, REDUCED CONSCIOUSNESS OF SURROUNDINGS,
LOSS OF TACTILE SENSATIONS, HEIGHTEND MENTAL ACTIVITY, RAPID LOSS
OF ABILITY TO DO TASKS.
Medical Cond Aggravated by Exposure:NONE SPECIFIED BY MANUFACTURER.

First Aid:PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF
OVEREXPOSURE TO NITROGEN, RESCUE PERSONNEL SHOULD BE EQUIPPED WITH
SELF-CONTAINED BREATHING APPARATUS. INHALATION: REMOVE TO FRESH
AIR. QUICK REMO VAL IS MOST IMPORTANT. GIVE MOUTH-TO-MOUTH
RESUSCITATION AND SUPPLEMENTAL OXYGEN. FURTHER TREATMENT SHOULD BE
SYMPTOMATIC AND SUPPORTIVE.

Extinguishing Media:NONFLAMMABLE. INERT GAS.

Spill Release Procedures:EVACUATE ALL PERSONNEL FROM AFFECTED AREA. USE
APPROPRIATE PROTECTIVE EQUIPMENT. IF LEAK IS IN CONTAINER OR
CONTAINER VALVE, CONTACT YOUR CLOSEST SUPPLIER LOCATION OR CALL THE
EMERGENCY TELEPHONE NUMB ER LISTED HEREIN.
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

Handling and Storage Precautions:PROTECT CYLINDERS FROM PHYSICAL
DAMAGE. STORE IN COOL, DRY, WELL VENTILATED AREA AWAY FROM HEAVILY
TRAFFICKED AREAS AND EMERGENCY EXITS.
Other Precautions:DO NOT ALLOW TEMPERATURE WHERE CYLINDERS ARE STORED
TO EXCEED 130F. CYLINDERS SHOULD BE STORED UPRIGHT AND FIRMLY
SECURED TO PREVENT FALLING OR BEING KNOCKED OVER. FULL AND EMPTY
CYLINERS SHOULD BE SE GREGATED.

Respiratory Protection:POSITIVE PRESSURE AIR LINE WITH MASK OR SELF-
CONTAINED BREATHING APPARATUS SHOULD BE AVAILABLE FOR EMERGENCY
USE.
Ventilation:LOCAL EXHAUST TO PREVENT ACCUMULATION OF HIGH
CONCENTRATIONS SO AS TO REDUCE THE OXYGEN LEVEL IN THE AIR TO < 18
MOLAR
Protective Gloves:ANY MATERIAL
Eye Protection:SAFETY GLASSES OR GOGGLES
Other Protective Equipment:SAFETY SHOES
Work Hygienic Practices:USE ONLY IN WELL VENTILATED AREAS.
Supplemental Safety and Health
VALVE PROTECTION SHOULD REMAIN IN PALCE UNLESS CONTAINER IS SECURED
WITH VALVE OUTLET PIPED TO USE POINT. DO NOT DRAG, SLIDE OR ROLL
CYLINERS. USE A SUITABLE HAND TRUCK FOR TRANSPORT. USE A PRESSURE R
EDUCING REGULATOR WHEN CONNECTING CYLINDER TO LOWER PRESSURE. USE A
CHECK VALVE OR TRAP TO PREVENT BACKFLOW.
