Section 4: FIRST AID MEASURES
4.1 EYES: Immediately flush with large quantities of water for 15 minutes. Hold eyelids apart during
irrigation to insure thorough flushing of the entire area of the eye and lids. Obtain medical attention if
irritation occurs.
4.2 SKIN: Immediately flush with large quantities of water. Remove contaminated clothing under a safety

4.3 INGESTION: If victim is conscious, give 2 to 4 glasses of water and induce vomiting by touching finger
to back of throat. Obtain medical attention.
4.4 INHALATION: Remove victim from contaminated atmosphere. If breathing is labored, administer
oxygen. If breathing has ceased, clear airway and start mouth to mouth resuscitation. If heart has stopped
beating, external heart massage should be applied. Obtain medical attention.
Section 5: FIRE FIGHTING MEASURES
5.1 FLAMMABLE PROPERTIES: (See Section 9, for additional flammable properties)
Heating this product will evolve ammonia.
Strong oxidizers such as nitrates, nitrites or chlorates can cause explosive mixtures if heated to dryness.
NFPA: Health - 1 Flammability - 0 Reactivity - 0
5.2 EXTINGUISHING MEDIA:
5.2.1 Suitable Extinguishing Media: Not flammable, use media suitable for combustibles involved in
fire.
5.2.2 Unsuitable Extinguishing Media: None known
5.3 PROTECTION OF FIREFIGHTERS:
5.3.1: Specific hazards arising from the chemical:
Physical hazards Heating (flames) of closed or sealed containers may cause violent rupture of
container due to thermal expansion of compressed gases.
Chemical hazards Heating causes release of ammonia vapors. Vapors are irritating to eyes,
Page 3 of 7
skin and respiratory tract. Heating to dryness may cause the release of ammonia, ammonium
sulfate, sulfur and oxides of sulfur.
5.3.2: Protective equipment and precautions for firefighters: Firefighters should wear self-
contained breathing apparatus and full fire-fighting turnout gear. Keep containers/storage vessels in fire
area cooled with water spray.
Section 6: ACCIDENTAL RELEASE MEASURES
6.1 PERSONAL PRECAUTIONS
Use personal protective equipment specified in Section 8. Isolate the hazard area and deny entry to
unnecessary and unprotected personnel.
6.2 ENVIRONMENTAL PRECAUTIONS
This product is not a water pollutant, but should be kept out of "waters of the US" because of potential
aquatic toxicity (See Section 12). This product is a non-hazardous liquid fertilizer solution designed to
supply nitrogen and sulfur to various crops.
6.3 METHODS OF CONTAINMENT
Small releases: Confine and absorb small releases on sand, earth or other inert absorbent.
Large releases: Shut off release if safe to do so. Dike spill area with earth, sand or other inert
absorbent to prevent runoff into surface waterways (potential aquatic toxicity). Recover as much of
the solution as possible. Treat remaining material as a small release (above)
6.4 METHODS FOR CLEANUP
Small release: For small areas use water spray to dilute to a weak fertilizer solution, taking care
not to let water runoff out of containment area.
Large release: Recover as much of the spilled product using portable pump and hoses. Treat
remaining material as a small release (above). Spread fertilizer material over a wide area to
avoid over fertilizing effects.
6.5 OTHER INFORMATION NA
Section 7: HANDLING and STORAGE
7.1 Handling: Avoid contact with eyes. Use only in a well ventilated area. Wash thoroughly after handling.
Avoid prolonged or repeated breathing of vapors. Avoid prolonged or repeated contact with the skin.
7.2 Storage: Store in well ventilated areas. Do not store combustibles in the area of storage vessels. Keep
away from any sources of heat or flame. Store tote and smaller containers out of direct sunlight at moderate
temperatures. (See Section 10.4 for materials of construction)
