SECTION 4 - FIRST AID MEASURES
4.1 Description of First Aid Measures
Inhalation
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a physician.
Ingestion
Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious person. Call a physician.
Skin
Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes before reuse.
Eyes
Immediately flush eyes with plenty of water for at least fifteen minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.
4.2 Most Important Symptoms and Effects, Both Acute and Delayed
Inhalation
Urea:
Symptoms may include coughing, shortness of breath. May be absorbed into the bloodstream with symptoms similar to ingestion.
Boric Acid:
May be absorbed from the mucous membranes of the respiratory tract, and depending on the amount of exposure could result in symptoms paralleling ingestion.
Tris-Base:
Coughing, shortness of breath.
Ingestion
Urea:
Symptoms may include nausea, vomiting, and diarrhea. May also cause headache, confusion and electrolyte depletion.
Boric Acid:
Depending on the amount of exposure, ingestion could result in the development of nausea, vomiting, diarrhea, drowsiness, rash, headache, fall in body temperature, low blood pressure, renal injury, cyanosis, coma, and death. Adult fatal dose reported at 5 to > 30 grams.
Tris-Base:
Symptoms may include nausea, vomiting, and diarrhea. Large oral doses may cause weakness, collapse, blood clotting, and coma. The estimated lethal dose of Tris Base is 50 grams dry solid.
Skin

Symptoms include redness, itching, and pain.
Boric Acid:
Symptoms of skin absorption parallel inhalation and ingestion.
Tris-Base:
Redness, itching, and pain.

4.3 Indication of Any Immediate Medical Attention and Special Treatment Needed
Unknown/not applicable
SECTION 5 - FIRE FIGHTING MEASURES
5.1 Extinguishing media
Use media appropriate to the primary cause of fire.
5.2 Special Hazards Arising from the Substance/Mixture
Hazardous Combustion Products
Thermal decomposition products may include toxic oxides of nitrogen and carbon.
Hazardous Decomposition Products
Urea decomposes upon heating and can form products including ammonia, oxides of nitrogen, cyanuric acid, cyanic acid, biuret, and carbon dioxide. Boric acid loses chemically combined water upon heating, forming metaboric acid (HBO2) at 212 - 221F, then pyroboric acid (H2B4O7) at 285-320F, and Boric anhydride at higher temperatures. The burning of tris-base may produce carbon monoxide, carbon dioxide and nitrogen oxides.
Hazardous Polymerization
Will not occur under normal conditions of use (See Sections 10.4 & 10.5).
5.3 Advice for Firefighters
In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode.
5.4 Further Information
No data available.
SECTION 6 - ACCIDENTAL RELEASE MEASURES
6.1 Personal Precautions
Wear appropriate protective equipment as specified in Section 8.
6.2 Environmental Precautions
Prevent discharge into the environment. Dike spills and stop leakage where practical. Do not allow material to enter drains.
6.3 Methods and Materials for Containment and Cleaning Up
Contain and clean up spill immediately, prevent from entering floor drains. Contain liquids using absorbents. Shovel all spill materials into disposal drum. Scrub spill area with detergent, flush with copious amounts of water.
6.4 References to Other Sections
For disposal information see Section 13. For protective clothing and equipment see Section 8.
SECTION 7 - HANDLING AND STORAGE
7.1 Precautions for Safe Handling
Avoid contact and inhalation. Do not get in eyes, on skin, on clothing. Wash thoroughly after handling.
7.2 Conditions for Safe Storage (including any incompatibles)
Keep in a tightly closed container, stored in a cooled, dry, ventilated area.
Incompatibles
Urea:
Urea reacts with calcium hypochlorite or sodium hypochlorite to form the explosive nitrogen trichloride. It is incompatible with sodium nitrite, gallium perchlorate, strong oxidizing agents (permanganate, dichromate, nitrate, chlorine), phosphorus penta
Boric Acid:
Potassium, acetic anhydride, alkalis, carbonates, and hydroxides.
Tris-Base:
No incompatibility data found.
7.3 Specific End Uses

8.2 Exposure Controls
Engineering Controls
A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source.
Respiratory Protection
For conditions of use where exposure to the dust or mist is apparent, a full-face dust/mist respirator may be worn. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator.
Eye Protection
Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Skin Protection
Wear protective gloves and clean body covering clothing.
