Section 3. Hazards Identification
Routes of entry: respiration, eyes, skin contact
Carcinogenicity: none
Target organs: eyes, lungs
Health impact on eye: Direct contact of the eyes with its dust might cause mechanical irritation.
Health impact on skin: Direct contact of the skin with its dust might cause slight skin dryness and slight irritation.
Health impact on digestive system: Inhalation of fine bentonite dust might cause mechanical irritation to the nose and throat..
Section 4. First-aid Measures
Eyes: Flush the eyes with plenty of water or 0.6% saline solution. If irritation or reddish swelling persists, see a doctor.
Skin: An ordinary emollient may eliminate dryness. If irritation or reddish swelling persists, see a doctor. In case of a bruise, clean the wound with dilute suds.
Digestive system: Since this material is not absorbed in the digestive system, it is thought as nontoxic to the body.
Respiratory system: If this occurs, move to fresh air immediately. In case of stop of respiration, take an artificial respiration and send the patient to the hospital immediately. Keep warm and have enough rest.
Emergency eye washing: If employees are likely to be exposed to high concentrations of air-borne dust, the employer shall provide a water source nearby to provide against accidents.
