Potential Health Effects
----------------------------------
Inhalation:
Inhalation of large amounts of dust may cause irritation to the respiratory tract.
Ingestion:
Extremely large oral dosages may produce gastrointestinal disturbances.
Skin Contact:
Possible irritation on prolonged contact with moist or sensitive areas of the skin.
Eye Contact:
No adverse effects expected but dust may cause mechanical irritation.
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
No information found.
4. First Aid Measures
Inhalation:
Remove to fresh air. Get medical attention for any breathing difficulty.
Ingestion:
Give several glasses of water to drink to dilute. If large amounts were swallowed, get
medical advice.
Skin Contact:
Wash exposed area with soap and water. Get medical advice if irritation develops.
Eye Contact:
Wash thoroughly with running water. Get medical advice if irritation develops.
5. Fire Fighting Measures
Fire:
As with most organic solids, fire is possible at elevated temperatures or by contact with
an ignition source.
http://www.jtbaker.com/msds/s3386.htm 1/1/99
SODIUM CITRATE Page 3 of 7
Explosion:
Fine dust dispersed in air in sufficient concentrations, and in the presence of an ignition
source is a potential dust explosion hazard.
Fire Extinguishing Media:
Water spray, dry chemical, alcohol foam, or carbon dioxide.
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.
6. Accidental Release Measures
Remove all sources of ignition. Ventilate area of leak or spill. Wear appropriate personal
protective equipment as specified in Section 8. Spills: Clean up spills in a manner that
does not disperse dust into the air. Use non-sparking tools and equipment. Reduce
airborne dust and prevent scattering by moistening with water. Pick up spill for recovery
or disposal and place in a closed container.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against
physical damage. Isolate from incompatible substances. 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:
- OSHA Permissible Exposure Limit (PEL):
15 mg/m3 total dust, 5 mg/m3 respirable fraction for nuisance dusts.
- ACGIH Threshold Limit Value (TLV):
10 mg/m3 total dust containing no asbestos and < 1% crystalline silica for Particulates
Not Otherwise Classified (PNOC).
Ventilation System:
In general, dilution ventilation is a satisfactory health hazard control for this substance.
However, if conditions of use create discomfort to the worker, a local exhaust system
should be considered.
Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded, a half-face dust/mist respirator may be worn for up to
ten times the exposure limit or the maximum use concentration specified by the
appropriate regulatory agency or respirator supplier, whichever is lowest. A full-face
piece dust/mist respirator may be worn up to 50 times the exposure limit, or the maximum
use concentration specified by the appropriate regulatory agency, or respirator supplier,
whichever is lowest. For emergencies or instances where the exposure levels are not
http://www.jtbaker.com/msds/s3386.htm 1/1/99
SODIUM CITRATE Page 4 of 7
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 protective gloves and clean body-covering clothing.
Eye Protection:
Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in
work area.
