Section 3 - Hazards Identification

EMERGENCY OVERVIEW

Causes severe burns.

Potential Health Effects

Eye: Liquid splashes may produce severe burns to skin and may cause

damage to eyes

Skin: Liquid splashes may produce severe burns to skin. Nitric Acid

highly corrosive to all parts of bodies.


4/19


Ingestion: Will immediately cause corrosion of and damage to the gastro-

intestinal track.

Inhalation: Fumes are corrosive to respiratory track and will cause

coughing, sore throat and laboured breathing. Fluid build up on

lung (Pulmonary Edema) may occur up to 48 hrs after exposure

and could prove fatal.

Long Term

Effects:

Acute effects predominate and their severity is such that

significant repeated or prolonged exposure is unlikely.

Repeated exposure to high level produces adverse effects on

lung and teeth.

Environment: Nitric acid is harmful to aquatic life.


5/19


Section 3 - Hazards Identification

Other: Not classes as oxidizing agent. Can display oxidizing propertiesand react with combustible materials. May react violently withreducing agents, metals and a number of other substances.Decomposition product includes nitrogen oxides and hydrogen.

Section 4 - First Aid Measures

Product: Speed is essential. Immediately remove contaminated clothing.Obtain medical attention immediately.

Eyes: Immediately irrigate the eyes with eyewash solution or cleanwater for at least 10 minutes. Continue irrigation until medicalattention can be obtained. Hold eyelids open during flushing.


6/19

MSDS FOR NITRIC ACID 60%Skin: Drench with water, remove contaminated clothing and wash or

shower the affected skin with plenty of water. Obtain

immediate medical attention.

Ingestion: Do not induce vomiting. If the person is conscious, wash out

mouth with water and give 2 or 3 glasses of water or milk to

drink. Obtain immediate medical attention and transport the

patient to hospital.

Inhalation: Move the injured person to fresh air at one. Keep the patient

warm and at rest. Administer oxygen if competent person isavailable. Perform artificial respiration, if breathing has

stopped or shows sign of failing. Obtain immediate medical

attention.

Further

medicaladvice:

Following exposure the patient should be kept under medical

review for at least 48 hours as delayed pulmonary edema maydevelo .

Section 5 - Fire Fighting Measures

Extinguishing

Media:

Foam, water and dry power. Use a water spray to cool Fire-

exposed containers and structures.

Specific

hazards if the

product is

involved in aFire:

Not combustible, but having oxidizing properties it may react

with many combustible materials causing Fire and releasing

toxic fumes (Nitrogen Oxide).

May explode on contact with a powerful reducing agent.Reacts with most common metals to liberate hydrogen which

can form explosive mixtures with air. Toxic fumes (oxide

nitrogen) may be given off.

Special

protectiveequipment:

Wear Self-contained breathing apparatus and full protective

clothing.


8/19


Section 6 - Accidental Release Measures

Personal

precautions

Put on protective equipment before entering danger area.

Ventilate area of spill or leak to disperse vapors.Environmental

Precautions:

Take care to avoid the contamination of water course and

drains. Inform appropriate authority in case of accidental

contamination of watercourses.


9/19


Methods for

cleaning:

Swill away small spillage with copious quantities of water.

Waste water must be disposed of correctly. Before

discharging sewage into treatment plants, neutralization is

generally required.Contain large spillage with sand or earth as necessary. Do not

use organic compounds, sawdust etc. neutralize cautiously

with soda ash and /or lime and recover for disposal.

Pump large amount into containers. Containers should

preferably be of: stainless steel or plastic. Do not use carbonsteel, rubberized steel, polypropylene. Seek advice from the

manufacturer if in doubt.


10/19


Section 7 - Handling and Storage

Handling: Wear eye and hand protection when handling small

quantities. Provide adequate ventilation in view of insidious

action of the fumes. When diluting, always add acid to water

not water to acid. Wear full protective equipment where there

is a risk of leaks or splashes.

Storage: Store in cool, well ventilated are, away from potential sources

of heat and direct sunlight. Keep away from combustiblematerials, reducing agents, strong bases. Protect containersfrom corrosion and physical damages. Containers shouldpreferably be of stainless steel. Seek advice from themanufacturer if in doubt.


11/19


Section 8 - Exposure Controls, Personal Protection

Engineering

Controls:

Local exhaust ventilation. Provide safety showers and eye

washing facility at any location where skin or eye contact can

occur.

Exposure

Limits:

ACGIH recommended valuesTLV/TW: 2 ppm = 5.2 mg/m3TLV-STEL: 4 ppm = 10 mg/m3

Personal

Protection:

Wear breathing apparatus if exposure levels exceed therecommended limits. Wear PVC gloves, rubber boots, PVCsuit. Use chemical safety goggles or full face shield.

Section 10 - Stability and Reactivity

Chemical

Stability:

The product is stable under normal conditions of storage and

handling.

Conditions toAvoid:

High temperatures.

Incompatibilities

with Other

Materials:

Contact with combustible materials, reducing agents,

alkalies, metallic powers, hydrogen sulphide, alcohols,

chlorates and carbides, carbon steel, monel, copper, and

several other metals and alloys.Hazardous

Decomposition

Products:

Contact with combustible material may cause fire. May

assist combustion. May react violently with reducing agents,

strong bases, organic materials, chloride and finally divided

metals. Reaction with most common metals liberates

hydrogen and toxic oxides of nitrogen. Exothermic reactionwith water. Corrosive ases / va ors.

Section 11 - Toxicological Information

General: Nitric acid is highly corrosive to all parts of the body.

Toxicity Data

(Skin Contact):

Pain, severe burns and brownish or yellow stains.

Prolonged and repeated exposures to diluted solution may

cause irritation, redness, drying and cracking of the skin.

Eye Contact: Immediate pain, severe burns, permanent corneal damage

which may result in blindness.

Inhalation: Mists and vapors may cause irritation of nose, throat andrespiratory tract, transient cough and broncho-constriction.

Severe over-exposure may result in lung collapse and

pulmonary edema which can be fatal.

Prolonged or repeated exposure to mists or vapors of nitric

acid may result in impaired lung function and possible

discoloration and erosion of teeth.


15/19


Ingestion: Pain, severe burning in the mouth, throat and damage to

gastro-intestinal tract.

Other Data: No adverse effect has been evaluated by IARC asregards carcinogenicity.


16/19


Section 12 - Ecological Information

Mobility: Soluble in water. High mobility in soil.

Persistence/Degradability:

There is evidence of slow degradation in soil and water.

Bio-

accumulation:

The product has low potential of bio-accumulation.

Ecotoxicity: Discharge into the environment to be avoided. Nitric acid isharmful to a be avoided. Nitric acid is harmful to aquatic life

even in low concentrations due to its acid nature.

Neutralization in generally required prior to discharge.

Can cause damage to vegetation. Inhibition of degradation

activity in activated sludge is not be anticipated during

correct introduction of low concentrations.


17/19


Section 13 - DISPOSAL CONSIDERATIONSGeneral: Nitric acid should be disposed of in accordance with local

or national legislation.
