SECTION 4 First aid measures

4.1. Description of first aid measures

► If product comes in contact with eyes remove the patient from gas source or contaminated area.
► Take the patient to the nearest eye wash, shower or other source of clean water.
► Open the eyelid(s) wide to allow the material to evaporate.
► Gently rinse the affected eye(s) with clean, cool water for at least 15 minutes. Have the patient lie or sit down and tilt the head
back. Hold the eyelid(s) open and pour water slowly over the eyeball(s) at the inner corners, letting the water run out of the
outer comers.
► The patient may be in great pain and wish to keep the eyes closed. It is important that the material is rinsed from the eyes to
prevent further damage.
Eye Contact ► Ensure that the patient looks up, and side to side as the eye is rinsed in order to better reach all parts of the eye(s)
► Transport to hospital or doctor.
► Even when no pain persists and vision is good, a doctor should examine the eye as delayed damage may occur.
► If the patient cannot tolerate light, protect the eyes with a clean, loosely tied bandage.
► Ensure verbal communication and physical contact with the patient.
DO NOT allow the patient to rub the eyes
DO NOT allow the patient to tightly shut the eyes
DO NOT introduce oil or ointment into the eye(s) without medical advice
DO NOT use hot or tepid water.
If skin or hair contact occurs:
Skin Contact ► Flush skin and hair with running water (and soap if available).
► Seek medical attention in event of irritation.
► Following exposure to gas, remove the patient from the gas source or contaminated area.
► NOTE: Personal Protective Equipment (PPE), including positive pressure self-contained breathing apparatus may be
required to assure the safety of the rescuer.
• Prostheses such as false teeth, which may block the airway, should be removed, where possible, prior to initiating first aid
procedures.
' If the patient is not breathing spontaneously, administer rescue breathing.
' If the patient does not have a pulse, administer CPR.
Inhalation
• If medical oxygen and appropriately trained personnel are available, administer 100% oxygen.
• Summon an emergency ambulance. If an ambulance is not available, contact a physician, hospital, or Poison Control Centre
for further instruction.
' Keep the patient warm, comfortable and at rest while awaiting medical care.
' MONITOR THE BREATHING AND PULSE, CONTINUOUSLY.
' Administer rescue breathing (preferably with a demand-valve resuscitator, bag-valve mask-device, or pocket mask as trained)
or CPR if necessary.
Ingestion ' Not considered a normal route of entry.

BASIC TREATMENT

· Establish a patent airway with suction where necessary.

• Watch for signs of respiratory insufficiency and assist ventilation as necessary.
· Administer oxygen by non-rebreather mask at 10 to 15 I/min.
• Monitor and treat, where necessary, for pulmonary oedema .
· Monitor and treat, where necessary, for shock.
• Anticipate seizures.

ADVANCED TREATMENT

• Consider orotracheal or nasotracheal intubation for airway control in unconscious patient or where respiratory arrest has occurred.
Positive-pressure ventilation using a bag-valve mask might be of use.
Monitor and treat, where necessary, for arrhythmias.
Start an IV D5W TKO. If signs of hypovolaemia are present use lactated Ringers solution. Fluid overload might create complications.
• Drug therapy should be considered for pulmonary oedema.
• Hypotension with signs of hypovolaemia requires the cautious administration of fluids. Fluid overload might create complications.
· Treat seizures with diazepam.
• Proparacaine hydrochloride should be used to assist eye irrigation.

SECTION 7 Handling and storage

7.1. Precautions for safe handling

Consider use in closed pressurised systems, fitted with temperature, pressure and safety relief valves which are
vented for safe dispersal. Use only properly specified equipment which is suitable for this product, its supply pressure
and temperature
The tubing network design connecting gas cylinders to the delivery system should include appropriate pressure
indicators and vacuum or suction lines.
Fully-welded types of pressure gauges, where the bourdon tube sensing element is welded to the gauge body,
are recommended.
Before connecting gas cylinders, ensure manifold is mechanically secure and does not containing another gas.
Safe handling
Before disconnecting gas cylinder, isolate supply line segment proximal to cylinder, remove trapped gas in supply line
with aid of vacuum pump
When connecting or replacing cylinders take care to avoid airborne particulates violently ejected when system
pressurises.
Consider the use of doubly-contained piping; diaphragm or bellows sealed, soft seat valves; backflow prevention
devices; flash arrestors; and flow monitoring or limiting devices. Gas cabinets, with appropriate exhaust treatment, are
recommended, as is automatic monitoring of the secondary enclosures and work areas for release.
DO NOT transfer gas from one cylinder to another.
Fire and explosion
See section 5

8.2. Exposure controls

Engineering controls are used to remove a hazard or place a barrier between the worker and the hazard. Well-designed
engineering controls can be highly effective in protecting workers and will typically be independent of worker interactions to
provide this high level of protection.
The basic types of engineering controls are:
8.2.1. Appropriate
Process controls which involve changing the way a job activity or process is done to reduce the risk.
engineering controls
Enclosure and/or isolation of emission source which keeps a selected hazard "physically" away from the worker and ventilation
that strategically "adds" and "removes" air in the work environment. Ventilation can remove or dilute an air contaminant if
designed properly. The design of a ventilation system must match the particular process and chemical or contaminant in use.
Employers may need to use multiple types of controls to prevent employee overexposure.

UW9V
► Safety glasses with side shields.
► Chemical goggles.
► Contact lenses may pose a special hazard; soft contact lenses may absorb and concentrate irritants. A written policy
Eye and face protection document, describing the wearing of lenses or restrictions on use, should be created for each workplace or task. This should
include a review of lens absorption and adsorption for the class of chemicals in use and an account of injury experience.
Medical and first-aid personnel should be trained in their removal and suitable equipment should be readily available. In the
event of chemical exposure, begin eye irrigation immediately and remove contact lens as soon as practicable.
Skin protection See Hand protection below
Hands/feet protection ' When handling sealed and suitably insulated cylinders wear cloth or leather gloves.

SECTION 11 Toxicological information

11.1. Information on toxicological effects

Inhalation of vapours may cause drowsiness and dizziness. This may be accompanied by narcosis, reduced alertness, loss of
reflexes, lack of coordination and vertigo.
Inhalation of vapours or aerosols (mists, fumes), generated by the material during the course of normal handling, may be
damaging lo the health of the individual.
Limited evidence or practical experience suggests that the material may produce irritation of the respiratory system, in a
significant number of individuals, following inhalation. In contrast to most organs, the lung is able to respond to a chemical insull
by first removing or neutralising the irritant and then repairing the damage. The repair process, which initially evolved to protect
mammalian lungs from foreign matter and antigens, may however, produce further lung damage resulting in the impairment of
gas exchange, the primary function of the lungs. Respiratory tract irritation often results in an inflammatory response involving the
recruitment and activation of many cell types, mainly derived from the vascular system.
Common, generalised symptoms associated with non-toxic gas inhalation include :
• central nervous system effects such as headache, confusion, dizziness, progressive stupor, coma and seizures;
► respiratory system complications may include tachypnoea and dyspnoea;
• cardiovascular effects may include circulatory collapse and arrhythmias;
Inhaled
► gastrointestinal effects may also be present and may include mucous membrane irritation and nausea and vomiting.

Material is highly volatile and may quickly form a concentrated atmosphere in confined or unventilated areas. The vapour may
displace and replace air in breathing zone, acting as a simple asphyxiant. This may happen with little warning of overexposure.
The use of a quantity of material in an unventilated or confined space may result in increased exposure and an irritating
atmosphere developing. Before starting consider control of exposure by mechanical ventilation.
Nitrogen is non-toxic but may replace oxygen in the inhaled air producing asphyxiation.
As the amount of inhaled oxygen is reduced from 21% to 14% (by volume), pulse rate and volume of breathing, increase.
Nitrogen inhaled under increased atmospheric pressure (>1.5 atmospheres), may dissolve in fat-containing brain-cells producing
anaesthesia and causing narcosis. Individuals exposed to increased pressures for some time and who are suddenly released
from the pressure may develop decompression sickness. Repeated exposures, without complete decompression, may result in
decompression sickness.
WARNING:- Inhalation of pure nitrogen atmosphere produces immediate loss of consciousness; death follows unless air/oxygen
breathing quickly resumes.
Overexposure is unlikely in this form.
Ingestion Not normally a hazard due to physical form of product.
Considered an unlikely route of entry in commercial/industrial environments
The material is not thought lo produce adverse health effects or skin irritation following contact (as classified by EC Directives
using animal models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable gloves
be used in an occupational setting.
Skin Contact
Open cuts, abraded or irritated skin should not be exposed to this material
Entry inlo the blood-stream through, for example, cuts, abrasions, punclure wounds or lesions, may produce systemic injury with
harmful effects. Examine the skin prior to the use of the material and ensure that any external damage is suitably protected.
Contact with cold gas may cause cryogenic (extreme low temperature) bums.

Eye
Although the material is not thought to be an irritant (as classified by EC Directives), direct contact with the eye may produce
transient discomfort characterised by tearing or conjunctival redness (as with windburn).

NITROGEN
Version No: 9.1

Direct contact with the eye may not cause irritation because of the extreme volatility of the gas; however concentrated
atmospheres may produce irritation after brief exposures ..
Long-term exposure to the product is not thought to produce chronic effects adverse to health (as classified by EC Directives
Chronic using animal models); nevertheless exposure by all routes should be minimised as a matter of course.
Principal route of occupational exposure to the gas is by inhalation.
