Health Hazards Data
=======================================================
Route Of Entry Inds - Inhalation: YES
Skin: NO
Ingestion: NO
Carcinogenicity Inds - NTP: NO
IARC: NO
OSHA: NO
Effects of Exposure: ACUTE: INHALATION: ASPHYXIANT. EFFECTS ARE DUE TO LACK OF
OXYGEN. MODERATE CONCENTRATIONS MAY CAUSE HEADACHE, DROWSINESS, DIZZINESS,
EXCITATION, EXCESS SALIVATION, VOMITING AND UNCONSCIOUSNESS. LACK O F OXYGEN
CAN KILL. SKIN CONTACT: NO HARM EXPECTED. INGESTION: THIS PRODUCT IS A GAS AT
NORMAL TEMPERATURE AND PRESSURE. EYE CONTACT: NO HARM EXPECTED. CHRONIC: NO
HARM EXPECTED. OTHER EFFECTS OF OVERE XPOSURE: NITROGEN IS AN ASPHYXIANT.
LACK OF OXYGEN CAN KILL. SIGNIFICANT LAB DATA WITH POSSIBLE RELEVANCE TO
HUMAN HEALTH HAZARD EVALUATION: NONE KNOWN. CARCINOGENICITY: NITROGEN IS NOT
LISTED BY NTP, OSHA OR IARC.
Signs And Symptions Of Overexposure: SEE HEALTH HAZARDS.
First Aid: INGESTION: CALL MD IMMEDIATELY (FP N). INHALATION: REMOVE TO FRESH
AIR. IF NOT BREATHING, GIVE ARTIFICIAL RESPIRATION. IF BREATHING IS
DIFFICULT, QUALIFIED PERSONNEL MAY GIVE OXYGEN. CALL A PHYSICIAN. SKIN
CONTACT: FLUSH WITH WATER. EYE CONTACT: FLUSH EYES WITH WARM WATER FOR AT
LEAST 15 MINUTES. HOLD THE EYELIDS OPEN AND AWAY FROM THE EYEBALLS TO ENSURE
THAT ALL SURFACES ARE FLUSHED THOROUGHLY. N OTES TO PHYSICIAN: THERE IS NO
SPECIFIC ANTIDOTE. THIS PRODUCT IS NEARLY INERT. TREATMENT OF OVEREXPOSURE
SHOULD BE DIRECTED AT THE CONTROL OF SYMPTOMS AND THE CLINICAL CONDITIONS.
REFER TO SECTION 16 .
=======================================================
Handling and Disposal
=======================================================
Spill Release Procedures: CAUTION! HIGH-PRESSURE GAS. IMMEDIATELY EVACUATE ALL
PERSONNEL FROM DANGER AREA. NITROGEN IS ASPHYXIANT. LACK OF OXYGEN CAN KILL.
USE NIOSH APPROVED SELF-CONTAINED BREATHING APPARATUS WHERE NEEDED. SH UT OFF
FLOW IF YOU CAN DO SO W/OUT RISK. VENTILATE AREA OR MOVE CYLINDER TO A
WELL-VENTILATED AREA. TEST FOR SUFFICIENT OXYGEN, ESPECIALLY IN CONFINED
SPACES, BEFORE ALLOWING REENTRY.
Waste Disposal Methods: PREVENT WASTE FROM CONTAMINATING THE SURROUNDING
ENVIRONMENT. KEEP PERSONNEL AWAY. DISCARD ANY PRODUCT, RESIDUE, DISPOSABLE
CONTAINER OR LINER IN AN ENVIRONMENTALLY ACCEPTABLE MANNER, IN FULL COMPLIAN
CE WITH FEDERAL, STATE AND LOCAL REGULATIONS. IF NECESSARY, CALL YOUR LOCAL
SUPPLIER FOR ASSISTANCE.
Handling And Storage Precautions: STORE & USE W/ADEQ VENT. FIRMLY SECURE
CYLS UPRIGHT TO KEEP THEM FROM FALLING/BEING KNOCKED OVER. SCREW VALVE PROT
CAPS FIRMLY IN PLACE BY HAND. STORE ONLY WHERE TEMP NOT >125F(52C). STORE
FULL & EMPT Y CYLS SEPARATELY. USE FIRST-IN, FIRST-OUT INVENTORY SYS TO
PVNT STORING FULL CYLS FOR LONG PERIODS.
Other Precautions: PROTECT CYLS FROM DMG. USE SUITABLE HAND TRUCK TO MOVE CYLS;
DO NOT DRAG, ROLL, SLIDE OR DROP. NEVER ATTEMPT TO LIFT CYL BY ITS CAP; CAP
IS INTENDED SOLELY TO PROTECT VALVE. NEVER INSERT OBJECT (EG WR ENCH,
SCREWDRIVER, PRY BAR) INTO CAP OPENINGS; DOING SO MAY DMG VALVE & CAUSE
LEAK. USE ADJUSTABLE ( SUPDAT)
=======================================================
Fire and Explosion Hazard Information
=======================================================
Extinguishing Media: NITROGEN CANNOT CATCH FIRE. USE MEDIA APPROPRIATE FOR
SURROUNDING FIRE.
Fire Fighting Procedures: USE NIOSH APPROVED SCBA AND FULL PROTECTIVE EQUIPMENT
(FP N). CAUTION! HIGH-PRESSURE GAS. EVACUATE ALL PERSONNEL FROM DANGER AREA.
IMMEDIATELY DELUGE CYLINDERS W/WATER FROM MAXIMUM DISTANCE UNTIL COOL , THEN
MOVE THEM AWAY FROM FIRE AREA IF W/OUT RISK. ON-SITE FIRE BRIGADES MUST
COMPLY W/OSHA 29 CFR 1910.156.
Unusual Fire/Explosion Hazard: NITROGEN CANNOT CATCH FIRE. HEAT OF FIRE CAN
BUILD PRESSURE IN CYLINDER & CAUSE IT TO RUPTURE. NO PART OF CYLINDER
SHOULD BE SUBJECTED TO TEMPERATURE HIGHER THAN 125F(52C). NITROGEN CYLINDERS
ARE EQUI PPED W/PRESSURE RELIEF DEVICE. (EXCEPTIONS MAY EXIST WHERE
AUTHORIZED BY DOT.) HAZARDOUS COMBUTION PRODUCTS: NONE KNOWN.
=======================================================
Control Measures
=======================================================
Respiratory Protection: NONE REQUIRED UNDER NORMAL USE. HOWEVER, NIOSH APPROVED
AIR SUPPLIED RESPIRATORS ARE REQUIRED WHILE WORKING IN CONFINED SPACES WITH
THIS PRODUCT. RESPIRATORY PROTECTION MUST CONFORM TO OSHA RULES AS S PECIFIED
IN 29 CFR 1910.134.
Ventilation: USE LOCAL EXHAUST SYS, IF NEC, TO PVNT OXYGEN DEFICIENCY. GEN
EXHST VENT MAY BE ACCEPTABLE IF IT CAN MAINTAIN ADEQ SUPPLY OF AIR. SPECIAL:
NONE. OTHER: NONE.
Protective Gloves: WORK GLOVES.
Eye Protection: ANSI APPROVED CHEMICAL WORKERS GOGGLES (FP N).
Other Protective Equipment: EYE WASH & DELUGE SHOWER MTG ANSI DESIGN CRITER (FP
N). METATARSAL SHOES FOR CYLINDER HANDLING. SELECT I/A/W OSHA 29 CFR 1910.132
& 1910.133. REGARDLESS OF PROT EQUIP, NEVER TOUCH LIVE ELECTRICAL PARTS.
Supplemental Safety and Health: OTHER PRECS: STRAP WRENCH TO REMOVE OVER-TIGHT
OR RUSTED CAPS. OPEN VALVE SLOWLY. IF VALVE IS HARD TO OPEN, DISCONTINUE USE
& CNTCT YOUR SUPPLIER. FOR OTHER PRECS IN USING NITROGEN, SEE SECTION 16.
