3. Hazards Identifications

 

Potential Health Effects

Primary Route(s) of Exposure          : Inhalation, skin, eyes.

Inhalation : Occasional mild irritation effects to the nose and throat may occur from inhalation of borate dusts at levels greater than 10 mg/m3.

Eye Contact: May irritate the eyes upon contact.

Skin Contact: May irritate the skin upon contact.

Ingestion: Colemanite is not intended for ingestion. Inorganic borate salts have low acute toxicity.

ACUTE (Short term)              : This product may cause mild irritation, redness, tearing and blurred vision to the eyes, and may cause mouth, throat and gastrointestinal tract irritation. It contains small amounts of orpiment and realgar as contaminant, which have low toxicity. Acute arsenic intoxication usually occur via ingestion, specifically arsenic trioxide, with homicidal or suicidal intent, although there have been reports of unusual cases resulting from occupational or environmental exposure. See section 8 for exposure controls.

 

4. First Aid Measures

 

Inhalation                   : Move person to fresh air. Seek medical attention if irritation

  persists.

Eye Contact                : Flush eyes with running water for at least 15 minutes. Seek

  medical attention if irritation persists.

Skin Contact               : Wash with running water for at least 15 minutes. Seek medical

  attention.

Ingestion                     : Observe individual; if symptoms develop, seek medical attention.

  Drink water to dilute material in stomach.

   scooped up for disposal as a non-hazardous waste.

 

7. Handing and Storage

 

Storage Temperature                        : Store in dry, covered warehouse.

Storage Pressure                               : Not applicable

General                                               : No special storage or handling procedures are

  required for  this material.

 

8. Exposure Control / Personal Protection

 

Personal protection:

Respiratory Protection          : Not required unless there is heavy dust occurrence

  in which case a protective mask is recommended.

Skin Protection                       : Use of gloves recommended.

Eye Protection                        : Safety goggles recommended in dusty areas. 

Other Information                  : Not absorbed when in contact with healthy skin or

                                                  eye, wash with plenty of water.

 

Engineering Controls :

 

General dilution ventilation and/or local exhaust ventilation should be provided as necessary to maintain exposures below regulatory limits. Dust collection systems may be necessary in some operations.

 

Environmental Exposure Controls: Borates are naturally occuring and are widely spread on earth.

11. Toxicological Information

 

Acute Toxicity: Not tested. Similar inorganic borate compounds are low in acute oral toxicity; LD50 of colemanite in rats is expected to be greater than 5,000 mg/kg of body weight.

Skin: Not tested. Similar inorganic borate compounds are low in acute dermal toxicity; LD50 of colemanite in rabbits is expected to be greater than 2,000 mg/kg of body weight.

Skin Irritation: Not tested. Not expected to be irritating to skin based experience with other similar inorganic borate compounds.

Eye Irritation: Not tested. Not expected to be irritating to eyes based experience with other similar inorganic borate compounds.

Carcinogenicity/Mutagenicity: Colemanite has not been tested. However, studies conducted with the chemically similar substance boric acid have reported no evidence of carcinogenicity in mies and mutagenic activity in a battery of short-term mutagenicity assays.

Reproductive: Colemanite has not been tested. However, human study of occupationally exposed borate worker population showed no adverse reproductive effects.

Realgar & Orpiment: The toxicity of arsenic ranges from very low to extremely high depending on chemical state. Metallic arsenic and arsenious sulfide have low toxicity; arsine, a gas, is extremely toxic. The toxicity of other organic and inorganic arsenic compounds varies. Although metallic arsenic and arsenic sulfides may be handled safely without special precautions, skin contact with all arsenical compounds should be avoided. Inorganic arsenic is a documented human carcinogen and has been classified by IARC in Group 1.

 

12. Ecological Information

 

The environmental effects of boron are minimal and most noticeable in the world of plants. Minimal quantities of this element is essential for plant growth and hence boron is added to fertilisers used in boron deficient soils. However concentrations as low as 1 ppm boron could be critical for sensitive plants (lemon. etc.) and 10 ppm for semi tolerant plants (mustard, radish). There is no permanent effect as boron gradually soluble in water. In diluted aqueus solutions the predominant boron species present is undissociated boric acid.

Phytotoxicity: Boron is an essential micronutrient for plants. However, it can be harmful to boron sensitive plants in higher quantities. Acute toxicity (72-hr EC50) for algea (selenastrum capricornutum) was determined as 53 mg B/l.

Environmental Fate: Boron and calcium are both ubiquitous in the enviroment and occur naturally in various mineral forms. Colemanite should be expected to decompose in the environment to stable calcium and boron containing mineral species.

Fish Toxicity: Boron naturally occurs in sea water and average concentration of 5 mg B/l. Acute toxicity (96-hr LC50) for under-yearling Coho salmon (oncorhynchus kisutch) in fresh water was determined as 447 mg B/l.

Bioaccumulation:

Species                        : Crassostrea gigas

Exposure Period           : 47 days at 8°C

            Concentration               : 40.5 B mg/l

            BCF                             : ca 4.5-8.5

            Test Substance : Sodium Metaborate

 

 

Low BCFs and reduction of tissue concentrations during exposures suggest regulation and that boron will not accumulate to high concentration.
