IV.   FIRE AND EXPLOSION HAZARDS DATA

Flash Point:  N/A

Autoignition Temperature:  N/E

Explosive Limits:  Upper:  N/A          Lower:  N/A

Extinguishing Media:  Use suitable extinguishing media for surrounding materials and type of fire.

Special Firefighting Procedures:  Firefighters must wear full face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes.  Fumes from fire are hazardous.  Isolate runoff to prevent environmental pollution.

Unusual Fire and Explosion Hazards:  Dissolves in water to form perrhenic acid, HReO₄.  Rhenium oxide is an oxidizer; contact with combustible material may cause fire.

 

 

V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

To the best of our knowledge the chemical, physical and toxicological properties of rhenium oxide have not been thoroughly investigated and recorded.

No toxic effects are known for rhenium metal.  Rhenium compounds may be irritating to the eyes and respiratory tract.

Acute Effects:

Inhalation:  May cause irritation to the respiratory tract.  May cause irritation of the nose, throat, lungs and possible chemical burns to mucous membranes.

Ingestion:  May cause chemical burns of the mouth, throat and gastrointestinal tract.

Skin:  Corrosive and strong irritant.  May cause severe irritation and chemical burns.

Eye:  Corrosive and strong irritant.  May cause chemical burns to eye tissue, visual impairment, including blindness.

Chronic Effects:

Inhalation:  May cause lung edema and laryngeal spasms.

Ingestion:  No chronic health effects recorded.

Skin:  Corrosive and strong irritant.  May cause dermatitis.

Eye:  Corrosive and strong irritant.

Target Organs:  May affect the respiratory system, skin and eyes.

Medical Conditions Generally Aggravated by Exposure:  Pre-existing respiratory and skin disorders.

Carcinogenicity:  NTP:  No      IARC:  No     OSHA:  No

 

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION:  Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult.  Seek medical attention immediately.

INGESTION:  Give 1-2 glasses of water or milk, do not induce vomiting; seek medical attention immediately.  Never give anything by mouth to an unconscious person.

SKIN:  Remove contaminated clothing, brush material off skin, wash with mild soap and water and seek medical attention immediately.

EYE:  Immediately flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes.  Seek medical attention immediately.

VII.   SPILL OR LEAK PROCEDURES

Steps to Be Taken in Case Material Is Released or Spilled:  Wear appropriate respiratory and protective equipment specified in Section VIII.  Isolate spill area and provide ventilation.  Vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal.  Take care not to raise dust.

Waste Disposal Method:  Dispose of in accordance with Local, State and Federal Regulations.

 

 

 

VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection:  NIOSH - approved dust, mist, vapor respirator.

Ventilation:  Handle in an inert gas in a controlled atmosphere.  Use local exhaust to maintain concentration at a low exposure level.  General exhaust is recommended.

Protective Gloves:  Rubber or neoprene gloves.

Eye Protection:  Safety goggles.

Other Protective Clothing or Equipment:  Protective gear suitable to prevent contamination.

 

 

IX.   SPECIAL PRECAUTIONS

Precautions to be Taken in Handling and Storage:  Store in tightly sealed container.  Keep out of direct sunlight.  Wash thoroughly after handling.

Other Precautions:  Rhenium oxide decomposes in water.  Handle and store in a controlled atmosphere and under an inert gas such as argon.  Rhenium oxide is an oxidizer.  Contact with combustible material may cause fire.

Work Practices:  Implement engineering and work practice controls to reduce and maintain concentration of exposure at low levels.  Use good housekeeping and sanitation practices.  Do not use tobacco or food in work area.  Wash thoroughly before eating and smoking.  Do not blow dust off clothing or skin with compressed air.  Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.
