IV.  FIRE AND EXPLOSION HAZARDS DATA

Flash Point:  N/A 

Autoignition Temperature:  N/A 

Explosive LimitsUpper:  N/A          Lower:  N/A

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

Special Fire Fighting 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 & Explosion Hazards:  When heated to decomposition zinc oxide may emit toxic fumes of ZnO.  May explode when mixed with chlorinated rubber.  Violent reaction with magnesium, linseed oil.

 

 

V.  HEALTH HAZARD INFORMATION

Effects of Exposure:

Zinc compounds have variable toxicity, but generally are of low toxicity.  Zinc is not inherently a toxic element.  However, when heated it evolves a fume of zinc oxide which, when inhaled fresh, can cause a disease known as “brass founders” “ague,” or “brass chills”.  Zinc oxide dust which is not freshly formed is virtually innocuous.  There is no cumulative effect form the inhalation of zinc fumes (Sax, Dangerous Properties of Industrial Materials, eighth edition).

Acute Effects:

Inhalation:  May cause  respiratory tract irritation with nasopharyngitis and laryngitis.

Ingestion:  Moderately toxic by ingestion.

Skin:  May cause irritation.

Eye:  May cause irritation

Chronic Effects:

Inhalation:  May cause human systemic effects.

Ingestion:  No chronic health effects recorded.

Skin:  No chronic health effects recorded.

Eye:  No chronic health effects recorded.

Target Organs:  No target organs recorded.

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

CarcinogenicityNTP:  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 and seek medical attention.

INGESTION:  Give 1-2 glasses of milk or water and induce vomiting; seek medical attention.  Never induce vomiting or give anything by mouth to an unconscious person.

SKIN:  Remove contaminated clothing; brush material off skin; wash affected area with mild soap and water; seek medical attention if symptoms persist.

EYE:  Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes.  Seek medical attention if symptoms persist.

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- Special Protection Information.  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 waste disposal regulations.

 

 

 

 

VIII.  SPECIAL PROTECTION INFORMATION

Respiratory Protection (Specify Type):  NIOSH/MSHA - approved dust respirator.

Ventilation:  Local exhaust ventilation may be necessary to control any air contaminants to within their PELs or TLVs during the use of this product.  Good general exhaust is recommended.

Protective Gloves:  Rubber gloves

Eye Protection:  Safety glasses

Other Protective Equipment or Clothing:  Protective gear suitable to prevent contamination.  Barrier creams may help prevent irritation in hypersensitive individuals.

 

 

IX.  ADDITIONAL COMMENTS

Precautions to Be Taken in Handling and Storage:  Store in a tightly sealed container.  Store in a cool, dry area.  Wash thoroughly after handling.

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.

DOT Regulations:

Hazard Class:  None
