Potential Health Effects
----------------------------------
Inhalation:
Causes irritation to the respiratory tract. Symptoms may include coughing, shortness of breath. May be caustic to nasal and lung tissues; causing severe burning.
Ingestion:
Ingestion of large amounts may cause vomiting, diarrhea of mucous and blood, lethargy, twitching of facial muscles and extremities, convulsions, fever, yellow discoloration of the skin, a fall in blood preassure, collapse, coma, and death. Kidney damage can also occur.
Skin Contact:
Can cause irritation due to caustic nature of material. Prolonged exposure can cause blistering and sloughing of the skin. Absorption of large amounts may cause symptoms similar to those of ingestion.
Eye Contact:
Eye contact may cause irritation with discomfort, tearing or blurry vision, eye corrosion with corneal or conjuctival ulceration.
Chronic Exposure:
Prolonged absorption may cause anorexia, weight loss, vomiting, convulsions, and anemia.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems, or impaired liver, kidney or respiratory function may be more susceptible to the effects of the substance.
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention immediately.
Ingestion:
If swallowed, DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything by mouth to an unconscious person. Get medical attention immediately.
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical attention immediately. Wash clothing before reuse. Thoroughly clean shoes before reuse.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.
Fire:
Not considered to be a fire hazard. Will not burn.
Explosion:
Not considered to be an explosion hazard. Releases oxygen at high temperatures.
Fire Extinguishing Media:
If involved in a fire, use water spray.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode.
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Sweep up and containerize for reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust dispersal. Caution: Reacts with water to give oxygen and strong alkali.
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Avoid high humidities and temperatures above 32C (90F) to prevent loss of oxygen and caking. Do not store with heavy metal salts or combustible organic matter. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
Airborne Exposure Limits:
None established.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved):
For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator (NIOSH type N95 or better filters) may be worn. If oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection:
Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.

White, crystalline granules.
