Potential Health Effects
----------------------------------
To the best of our knowledge, the chemical, physical, and toxicological properties have not been thoroughly investigated.
Inhalation:
Irritation of respiratory system, may be harmful.
Ingestion:
May be irritant to the gastro-intestinal tract. may be harmful.
Skin Contact:
May be irritant may be harmful.
Eye Contact:
May be irritant
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
No information found.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Ingestion:
Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious person.
Skin Contact:
In case of contact, immediately wash skin with plenty of soap and water for at least 15 minutes.
Eye Contact:
In case of eye contact, immediately flush with plenty of water for at least 15 minutes. Get immediate medical attention.
Fire:
Not expected to be a fire hazard.
Explosion:
None identified.
Fire Extinguishing Media:
Water, dry chemical, foam or carbon dioxide.
Special Information:
Firefighters should wear proper protective equipment and self-contained breathing apparatus with full facepiece operated in positive pressure mode.
Take up by mechanical means (avoid dust formation) and place into sealed containers for adequate disposal. DO NOT allow to enter in the sewage or ground waters. Wash contaminated area well with soap and water.
Store at room temperature. Keep containers tightly closed and dry. Avoid contact with skin and eyes. Avoid dust formation Store in a dry area. Material is hygroscopic. Use with adequate ventilation. Keep container closed. Wash thoroughly after handling. 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 the substance is apparent and engineering controls are not feasble, consult an industrial hygienist. For emergencies, or instances where the exposure levels are not known, use a full-facepiece 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 and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures:
There is insufficient data in the published literature to assign complete numerical SAF-T-DATA* ratings and laboratory protective equipment for this product. Special precautions must be used in storage, use and handling. Protective equipment for laboratory bench use should be chosen using professional judgment based on the size and type of reaction or test to be conducted and the available ventilation, with overriding consideration to minimize contact with the chemical.
