M.S.D.S. 0379
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Prompt action is essential.
Ingestion:
Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious
person. Get medical attention.
Skin Contact: In case of contact, flush skin with water.
Eye Contact: In case of eye contact, immediately flush with plenty of water for at least 15 minutes.
Note to Physician: This material is anticipated to have low toxicity. Treatment is symptomatic and supportive.
========================================================================
PREVENTATIVE MEASURES
========================================================================
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): Not expected to require personal respirator usage.
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 judgement 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.
Handling and Storage:
Keep container tightly closed. Suitable for any general chemical storage area. 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.
========================================================================
ENVIRONMENTAL PROTECTION DATA
========================================================================
Wear self-contained breathing apparatus and full protective clothing. With clean shovel, carefully place material
into clean, dry container and cover; remove from area. Flush spill area with water.
