No information found.
Aggravation of Pre-existing Conditions:
No information found.
4. First
Aid Measures
Inhalation:
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.
5. Fire
Fighting Measures
Fire:
Not expected to be a fire hazard.
Explosion:
None identified.
Fire Extinguishing Media:
Use extinguishing media appropriate for surrounding fire.
Special Information:
Firefighters should wear proper protective equipment and self-contained
breathing apparatus with full face piece operated in positive pressure mode.
6.
Accidental Release Measures
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.
7.
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.
8.
Exposure Controls/Personal Protection
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 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.
