                           Section III - Hazard Identification

Summary of Acute Health Hazards

Ingestion: Ingestion causes burning pain in mouth, throat, stomach, and thorax,

constriction of throat, and coughing. This is soon followed by vomiting of blood or by

passage of loose stools containing blood. Ingestion of 3-4 ml may be fatal.

Inhalation: If inhaled, will cause nausea, vomiting, breathing difficulty, and convulsions.

Shock or loss of consciousness may result. Brief exposure to 5000 ppm may be fatal.

Skin: Absorption; Ammonia, because of its alkalinity and water solubility, tends to

break down and disrupt the outer cell layers, permitting rapid penetration. Even so,

ammonia is not a systemic poison and the effects will be limited to local effects. Contact;

Causes smarting of the skin and first-degree burns on short exposure. May cause second-

degree burns on long exposure.

Eyes: Vapor is irritating to the eyes. Liquid will cause burns.

Signs and Symptoms of Exposure: Burning of the eyes, conjunctivitis, skin irritation,

swelling of the eyelids and lips, dry red mouth and tongue, burning in the throat, and

coughing. In more severe cases of exposure, difficulty in breathing, signs and symptoms

of lung congestion, and, ultimately, death from respiratory failure due to pulmonary

edema may occur.

Effects of Overexposure: Irritation and possible burns of the skin and mucous

membranes. Headache, salivation, nausea, and vomiting. Difficult or labored breathing

and cough with bloody mucous discharge. Bronchitis, laryngitis, hemoptysis, and

pulmonary edema or pneumonitis. Ulceration of the conjunctiva and cornea, and corneal

and lenticular opacities. Damage to the eyes may be permanent.

Medical Conditions Generally Aggravated by Exposure: Ammonia is a respiratory

irritant. persons with impaired pulmonary function may be at increased risk from

exposure.

                             Section IV - First Aid Measures

Ingestion: Do Not Induce Vomiting. If person is conscious, give large quantities of

water and, if possible, diluted vinegar, lemon juice, orange juice, or other citric juices to

neutralize the ammonia. Delay may cause perforation of esophagus or stomach. OBTAIN

MEDICAL ATTENTION.

Inhalation: Remove victim to fresh air. Give oxygen if breathing is difficult. If breathing

has stopped, start artifical respiration. Keep victim calm and resting. OBTAIN

MEDICAL ATTENTION.

Skin: Apply water immediately to exposed areas of skin and continue for at least 15

minutes. Remove contaminated clothing while continuing to apply water. Do not apply

salves or ointments to affected areas. OBTAIN MEDICAL ATTENTION.

Eyes: Immediately flush with flowing water for at least 15 minutes with the eyelids held

apart. OBTAIN MEDICAL ATTENTION.

                           Section V - Fire Fighting Measures

                                             Autoignition Temperature: 850o C; 1560o F

Flash Point: N/A

Lower Explosive Limit: 16% by volume Upper Explosive Limit: 25% by volume

Ammonia gas                          Ammonia gas

Unusual Fire and Explosion Hazards: The presence of oil or other combustible

materials will increase the fire hazard. The explosive (flammable) range of ammonia is

broadened by a mixture of oxygen replacing air, and by temperature and pressure higher

than atmospheric.

Extinguishing Media: Water spray or fog type streams. Chemical or CO2 should be used

on small fires only.

Special Firefighting Procedures: Stop the flow of liquid. Use water to keep fire exposed

containers cool and to protect men affecting the shut off. Wear self-contained breathing

apparatus and full protective clothing. Approach fire upwind and evacuate area

downwind if needed.

                       Section VI - Accidental Release Measures

Stop the flow. Wear self-contained breathing apparatus and full protective clothing.

Approach spill from upwind and evacuate area downwind. Prevent runoff from entering

streams, drinking water supply or sewers. Dike to contain spill. Dilute with water, if

necessary to reduce ammonia vaporization. Can be neutralized with dilute phosphoric or

sulfuric acids. Vinegar will effectively neutralize small spills of aqua ammonia.

                          Section VII - Handling and Storage

Avoid heating containers of aqua ammonia. Avoid storing in close proximity to strong

acids. Avoid contact with skin and eyes. Avoid inhalation of vapors.

Other Precautions: Harmful to aquatic life in very low concentrations. May be

dangerous if it enters water intakes. Notify local health and wildlife officials. Do not

contaminate any body of water by direct application, cleaning of equipment or disposal.

                Section VIII - Exposure Controls/Personal Protection

Respiratory Protection: Unless ventilation is adequate to keep airborne concentrations

below the exposure standard, wear approved respiratory protection such as an ammonia

canister mask or an approved air supplied respirator. Canister or cartridge type masks

must not be used above their exposure limits. From 0-200 ppm, a cartridge type 1/2 mask

respirator is needed. From 200-500 ppm a type "N" gas mask with full face piece is

needed. Over 500 ppm a self-contained breathing apparatus (SCBA) is required.

Ventilation: Local exhaust is essential. Spark-proof fans desirable with mechanical

ventilation. Ducts should be located at ceiling level and lead upwards to the outside.

Local exhaust must be adequate to reduce ammonia concentration below 25 ppm.

Protective Clothing: Rubber boots, gloves, apron, and coat. Use of protective oil will

reduce skin irritation from ammonia.

Eye Protection: Tight fitting chemical safety and splash-proof goggles and/or a splash-

proof faceshield must be worn if there is a likelihood of exposure. Persons subject to

ammonia exposure must not wear contact lenses.

Other Protective Clothing or Equipment: Eyewash fountain and safety shower should

be available in the work area.

Work/Hygienic Practices: Avoid contact with skin and avoid breathing vapors. Do not

eat, drink, or smoke in work area. Wash hands before eating, drinking, or using restroom.
