LD50: None. LC50: None.
03. HAZARDS IDENTIFICATION

EMERGENCY OVERVIEW:

Warning:
High pressure gas.

Can cause rapid suffocation.

Do not breathe gas.

Self contained breathing apparatus may be required by rescue workers.

Potential Health Effects Information:

Routes of Exposure:

Inhalation:
Simple asphyxiant. Nitrogen is nontoxic, but may cause suffocation by displacing

the oxygen in air. Exposure to oxygen-deficient atmosphere (<19.5%) may cause

dizziness, drowsiness, nausea, vomiting, excess salivation, diminished mental

alertness, loss of consciousness and death. Exposure to atmospheres containing

8-10% or less oxygen will bring about unconsciousness without warning and so

quickly that the individuals cannot help or protect themselves. Lack of sufficient

oxygen may cause serious injury or death.

Eye:
None.

Skin:
None.

Chronic Effects:
None established.

Medical Conditions Aggravated By
None.

Overexposure:

Other Effects Of Overexposure:
None.

Carcinogenicity:
Nitrogen is not listed by NTP, OSHA, or IARC
04. FIRST AID MEASURES

Inhalation:
Persons suffering from lack of oxygen should be removed to fresh air. If victim is

not breathing, administer artificial respiration. If breathing is difficult, administer

oxygen. Obtain prompt medical attention.

Skin:
None.

Eye:
None.

Ingestion:
None.

Notes To Physician:
None.
05. FIRE FIGHTING MEASURES

Flash Point:
Not applicable; Gas.

Auto ignition:
Nonflammable.

Flammable Limits - Lower:
Not applicable.

Flammable Limits - Upper:
Not applicable.

Extinguishing Media:
Nitrogen is nonflammable and does not support combustion. Use extinguishing

media appropriate for the surrounding fire.

Fire Fighting Instructions:
Nitrogen is a simple asphyxiant. If possible, remove nitrogen cylinders from fire

area or cool with water. Do not direct water spray at the container vent.

Self-contained breathing apparatus may be required for rescue workers. Evacuate

this area.

Fire And Explosion Hazards:
Upon exposure to intense heat or flame cylinder may vent rapidly and/or rupture

violently. Most cylinders are designed to vent contents when exposed to elevated

temperatures. Pressure in a container can build up due to heat and it may rupture if

pressure relief devices should fail to function.

Hazardous Combustion Products:
None known.

Sensitivity To Static Discharge:
Not applicable.

Sensitivity To Mechanical Impact:
None.
06. ACCIDENTAL RELEASE MEASURES

Evacuate:
Evacuate all personnel from the affected area. Shut off source of Nitrogen if

possible without risk. Ventilate area or remove leaking containers to a well

ventilated location. If leaking from cylinder or its valve, contact your supplier.
07. HANDLING AND STORAGE

Storage:
Store and use with adequate ventilation. Cylinders should be stored upright with

valve protection cap in place and firmly secured to prevent falling or being knocked

over. Protect cylinders from physical damage; do not drag, roll, slide or drop. Do

not allow storage area temperature to exceed 125F (52C). Full and empty

cylinders should be segregated. Use a first-in, first-out inventory system to prevent

full containers from being stored for long periods of time

Handling:
Use a suitable hand truck for cylinder movement. Never attempt to lift a cylinder

by its valve protection cap. Keep cylinders and their valves free from oil and

grease. Open valve slowly. If user experiences difficulty operating cylinder valve,

discontinue use and contact supplier. Never insert an object (e.g., wrench,

screwdriver, pry bar, etc.) into valve cap openings. Doing so may damage valve,

causing a leak to occur. Never strike an arc on a compressed gas cylinder or make

a cylinder a part of an electrical circuit. Use an adjustable strap wrench to remove

over-tight or rusted caps. For additional precautions in using nitrogen see Section 16

- Other Information.
08. EXPOSURE CONTROLS - PERSONAL PROTECTION

Engineering Controls:

Ventilation:
Natural or mechanical to prevent oxygen-deficient atmospheres under 19.5%

oxygen.

Personal Protective Equipment (PPE):

Skin Protection:

Glasses:
Safety glasses are recommended when handling cylinders.

Shoes:
Safety shoes are recommended when handling cylinders.

Gloves:
Work gloves are recommended when handling cylinders.

Respirator:
None required in general use.

Emergency Use:
Self-contained breathing apparatus (SCBA) or positive pressure airline with mask

are to be used in oxygen-deficient atmosphere. Respirators will not function.
