SECTION 3: HAZARDS INDENTIFICATION

EMERGENCY OVERVIEW: 1)

Colorless gas or compressed liquid with extremely pungent odor

Liquid ammonia reacts

violently with

water. Vapor cloud is produced

Avoid contact with liquid and vapor

Stay upwind and use water spray to absorb vapor

Not flammable under conditions likely to be encountered outdoors

Stop discharge if possible

POTENTIAL HEALTH EFFECTS:
ROUTES OF ENTRY:

Inhalation, Skin Contact, Eye Contact, Ingestion

TARGET ORGANS:

Eyes, skin and respiratory system

EYE CONTACT:

Exposure to liquid or high concentrations of vapor can cause painful, instant and possibly irreversible damage to

tissue such as the conjunctiva, cornea and lens.

SKIN CONTACT:

Prolonged contact with high concentrations can cause painful tissue damage, frostbite and serious chemical burns.

INHALATION:

Depending on exposure concentration and durationís, effects can vary from none or only mild irritation, to obstruction

of breathing from laryngeal and bronchial spasm, to edema and severe damage of the mucous membranes of the respiratory tract with

possible fatal results. Latent edema and residual reduction in pulmonary function may occur.

INGESTION:

Tissue damage, chemical burns, nausea and vomiting can occur. Ammonia is a gas under normal atmospheric conditions

and ingestion is unlikely.

CARCINOGENICITY:

NTP? No IARC? No OSHA? No

SECTION 4: FIRST AID MEASURES

EYE CONTACT:

Flush with large amount of water for at least 15 minutes then immediately seek medical aid.

SKIN CONTACT:

Immediately flush with large quantities of water for at least 15 minutes while removing clothing. Clothing frozen to the

skin should be thawed with water before removal. Seek immediate medical aid.

INHALATION:

Remove from exposure. If breathing has stopped or is difficult, administer artificial respiration or oxygen as needed.

Seek immediate medical aid.

INGESTION:

Do not induce vomiting. Have the victim drink large quantities of water if conscious. Immediately seek medical aid. Never

give anything by mouth to an unconscious person.

SECTION 5: FIRE FIGHTING MEASURES

FLASH POINT(method used):

Not Applicable

FLAMMABLE LIMITS:

16-25% in air

EXTINGUISHING MEDIA:

With a source of ignition, ammonia will burn in the range of 16-25% in air. Stop flow of gas or liquid.

SPECIAL FIRE FIGHTING PROCEDURES:

Move containers from fire zone if possible; if not, use water to cool fire exposed

containers. Use water spray to control vapors. Do not put water directly on liquid ammonia. Personnel must be equipped with

appropriate protective clothing and respiratory protection.

NFPA HAZARD CLASSIFICATION:

Health: 3

Flammability: 1

Reactivity: 0 (least-0



4-highest)

SECTION 6: ACCIDENTAL RELEASE MEASURES

Release of 100 lbs. or more of ammonia within 24 hours must be immediately (within minutes) reported to the National Response Center at

1-800-424-8802, as well as appropriate local and state agencies.

Suggested Local Action:

Stop leak if feasible. Avoid breathing ammonia.

Evacuate personnel not equipped with protective clothing and equipment. Use copious amounts of water spray or fog to absorb ammonia
vapor. DO NOT put water on liquid ammonia. Contain run-off to prevent ammonia from entering a stream, lake, sewer, or ditch. Any
release of this material, during the course of loading, transporting, unloading or temporary storage, must be reported to U.S. D.O.T. as
required by CFR 171.15 and 171.16.

SECTION 7: HANDLING AND STORAGE

Refer to the ANSI K61.1 standard for storage and handling information. Protect containers from physical damage and temperatures

exceeding 120∞F. Use only approved storage systems. Zinc, copper, silver, cadmium and their alloys must not be used in ammonia systems

since they can be rapidly corroded by it. Avoid hydrostatic pressure, which can cause equipment rupture, by adhering to proper filling

procedures and the use of hydrostatic pressure relief valves where appropriate.
