Section 4: First-Aid Measures

Emergency and First Aid Procedures:

Causes burns by all exposure routes. Product is a corrosive material. Use of gastric lavage or emesis is contraindicated. Possible perforation of stomach or esophagus should be investigated: Ingestion causes severe swelling, severe damage to the delicate tissue and danger of perforation.

If in eyes:

Flush eyes with plenty of water for at least 15 minutes.  Remove contact lenses if able to do so.  Get medical attention/advice.

If on skin or clothing:

Flush skin with plenty of water for at least 15 minutes and wash with soap and water.  Remove contaminated clothing and shoes.  If irritation persists, consult a physician.

If inhaled:

Move to fresh air. If breathing is difficult, give oxygen. Do not use mouth-to-mouth resuscitation if victim ingested or inhaled the substance; induce artificial respiration with a respiratory medical device. Immediate medical attention is required.

If swallowed:

Do not induce vomiting. Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a doctor.



Section 5: Fire-Fighting Measures

Flash Point:



Non flammable  

Products of combustion:

Corrosive Material. Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Keep product and empty container away from heat and sources of ignition. Sodium oxides Carbon monoxide (CO) Carbon dioxide (CO2)

Extinguishing Media:

Use water-spray, dry chemical, or foam. Tailor extinguishing media to surrounding fire.

Protective equipment and precautions for firefighters:

As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full protective gear.

Section 6:  Accidental Release Measures

Personal precautions:

Wear self-contained breathing apparatus and protective suit. Evacuate personnel to safe areas. Ensure adequate ventilation. Do not get in eyes, on skin, or on clothing.

Environmental Precautions:

If safe to do so, avoid the dispersal of spilled material and contact with soil, waterways, drains, and sewers.  Inform the relevant authorities if the product has caused environmental pollution. Collect spillage.

Containment and cleanup:

If safe to do so, stop the leak/spill and dike the area. Ventilate the area if spilled in confined space or other poorly ventilated areas. Absorb spill with inert material (e.g. vermiculite, sand or earth). Collect  material in a clean container for disposal according to local regulations. Spilled liquid and dried film are slippery. Use care to avoid falls.



Section 7:  Handling and Storage

Safe handling:

Use caution while handling - material is corrosive.  Use appropriate personal protective equipment.  Handle in a well-ventilated area.  Handle in a manner consistent with good industrial/manufacturing techniques and practices.  Wash hands thoroughly with soap and water after use.  Remove contaminated clothing and protective equipment before entering eating area.  Avoid contact with eyes, skin, and clothing.

Safe storage:

Keep containers tightly closed in a cool, dry, well-ventilated place away from direct sunlight.  Containers which are opened must be carefully resealed and kept upright to prevent leakage.  Store away from incompatible materials.


Section 8:  Exposure Controls/Personal Protection

Exposure limits:

OSHA PEL (Permissible Exposure Limit):  (Vacated) Ceiling: 2 mg/m3 TWA: 2 mg/m3


ACGIH (American Conference of Governmental Industrial Hygienists) TLV (Short Term):  Ceiling: 2 mg/m3


NIOSH REL (Short Term):  IDLH: 10 mg/m3 Ceiling: 2 mg/m3

Engineering controls:

Use in well-ventilated area. Ensure water is available nearby. Provide readily accessible eye wash stations and safety showers.

Personal protective equipment:

Chemical resistant gloves, protective clothing, chemical safety glasses, face protection. Respirator protection is not normally required.

Acute Toxicity:

Oral Toxicity (LD50), oral, rabbit: 1350 mg/kg   Dermal Toxicity (LD50), oral, rabbit: not listed

Effects from short- and long-term exposure:

Inhalation may cause respiratory irritation.  Avoid contact which can cause serious irritation, redness, or severe burns. Pre-existing skin conditions may be aggravated by prolonged or repeated exposure. May be harmful if swallowed.  Product is a corrosive material. Use of gastric lavage or emesis is contraindicated. Possible perforation of stomach or esophagus should be investigated: Ingestion causes severe swelling, severe damage to the delicate tissue and danger of perforation.


No component in this product is identified as carcinogenic by IARC, NTP, ACGIH, or OSHA.
