Inhalation:             Yes

Skin:                       Yes

Ingestion:              Yes

 

EFFECTS OF OVEREXPOSURE: A mildly hazardous product, which can irritate skin and eyes and is expected to have moderate inhalation or ingestion toxicity.  May produce hazardous vapors, including nitrous oxide and cyanide, if heated to decomposition.  To the best of our knowledge, the chemical, physical and toxicological properties have not been thoroughly investigated.

 

ACUTE EFFECTS

 

EYE EXPOSURE:  May cause reddening and irritation of the eye.

 

SKIN OVEREXPOSURE: May cause irritation to skin consisting of reddening, itching, and pain.

 

INHALATION: May cause irritation of the throat, coughing, shortness of breath and respiratory tract irritation.

 

INGESTION:  May be harmful if swallowed causing psychosis, vomiting, disorientation, weakness, low blood pressure, and convulsions.


4. FIRST AID

 

FIRST AID FOR EYES:  Check for and remove contact lenses.  Flush with water in an eyewash for at least 15 minutes, holding eyelids open.  Do not use eye ointment.  Obtain medical attention if discomfort or medical symptoms persist.

 

FIRST AID FOR SKIN: Remove contaminated clothing and wipe off excess solution from skin.  Flush area with water for 10-15 min.  Use deluge safety shower to decontaminate large areas of body surface with running water and nonabrasive soap.  Obtain medical attention if discomfort or symptoms persist.

 

FIRST AID FOR INHALATION: Remove person to fresh air.  Monitor for respiratory distress and start artificial respiration, if needed.  Obtain medical attention if discomfort or symptoms persist.

 

FIRST AID FOR INGESTION: Remove dentures, if any.  Have conscious person drink several glasses of water or milk. Induce vomiting by sticking finger in throat.  Lower head so vomit will not reenter the mouth or throat.  Never give an unconscious person anything to ingest.  Obtain medical attention.


5. FIRE AND EXPLOSION HAZARD DATA

 

Combustible: Yes

Flash point: 59 C  (D93 Method A)

Autoignition temperature:  N/A

Flammable limits in air by volume, percent:     lower: N/A; upper: N/A

Transportation of dangerous goods flammability class: Combustible

 

EXTINGUISHING MEDIA:  Product may contribute to a fire at elevated temperatures or by contact with an ignition source.  Use water spray, CO2, dry chemical powder, alcohol or polymer foam.

 

FIREFIGHTING PROCEDURES: Wear positive pressure, self-contained breathing apparatus and protective clothing. Prevent contact with skin and eyes.  Unusual fire and explosion hazards: emits toxic fumes under fire conditions, including carbon and nitrogen oxides, sulfur oxides, hydrogen cyanide and ammonia.


6. ACCIDENTAL RELEASE MEASURES

 

Note that accidental releases may be subject to special reporting requirements and other regulatory mandates.  Check and comply with applicable laws and regulations.

 

PERSONAL PROTECTIVE EQUIPMENT FOR SPILL CONDITIONS:  Use gloves, boots, and impermeable clothing to avoid skin contact.  Use chemical goggles, face shield, or other appropriate eye protection. 

 

SPILL AND LEAK RESPONSE:  Evacuate area, allowing trained personnel to use pre-planned procedures to perform cleanup.  Wear personal protective equipment as required.  Remove all sources of ignition.  Contain liquid with absorbant material.  Decontaminate and ventilate area.  Place spill residue in sealed double bags.  Dispose of contaminated material in accordance with federal, state and local hazardous waste disposal regulations.


7. HANDLING AND STORAGE

 

IRRITANT. Keep container tightly closed in a cool, dry area.  Avoid contact with acids.  Avoid skin contact and inhalation.  Wear eye protection and gloves when handling.  Store reagent at room temperature (15-30 C), under standard atmospheric conditions.  Keep container tightly sealed to minimize evaporation.  The solution is suitable for most laboratory storage areas.  Avoid eating and smoking in work areas.  Wash hands thoroughly after using this material.


8. EXPOSURE CONTROLS / PERSONAL PROTECTION

 

GENERAL PROTECTION AND PRECAUTIONS

 

Laboratory exhaust hood or local exhaust should be used when working with large volumes of reagent.  Ensure availability of safety shower and eyewash before using.
