Potential Health Effects
----------------------------------
Inhalation:
(tm)
Causes irritation to the respiratory
tract. Symptoms may include coughing, shortness of
breath. Behaves as a
moderately strong
alkali; intense exposure may result in the
destruction of mucous membranes. May cause
asthmatic bronchitis, chemical
pneumonitis, or pulmonary edema.
Ingestion:
Causes irritation
to the gastrointestinal tract. Symptoms may
include nausea, vomiting and diarrhea. May
cause mild burning of mouth, throat,
and stomach. Its alkaline nature may injure the
esophagus and digestive
tract. Aqueous,
highly alkaline solutions may produce caustic
burns.
Skin Contact:
Causes
irritation
to
skin.
Symptoms
include
redness,
itching,
and
pain.
Extent
of
damage
depends
on
duration of contact. More serious
effects may occur if the skin is moist. Aqueous,
highly alkaline solutions
may produce
caustic burns.
Eye Contact:
Causes irritation to the eyes, may have
possible corneal damage, and its aqueous, highly
alkaline solutions
may produce caustic
burns.
Chronic Exposure:
Repeated
exposure
may cause symptoms similar
to
those
listed
for
acute
effects.
May cause
permanent
tissue damage to
the skin and eyes.
Aggravation of Pre-
existing Conditions:
No information
found.
4.
First Aid Measures
Inhalation:
Remove to fresh air. If not breathing,
give artificial respiration. If breathing is
difficult, give oxygen. Get
medical
attention.
Ingestion:
Do NOT
induce vomiting. Give large amounts of water.
Never give anything by mouth to an unconscious
person. Get medical attention.
Skin Contact:
Immediately
flush skin with plenty of soap and water for at
least 15 minutes. Remove contaminated clothing
and shoes. Get medical attention. 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.
5. Fire
Fighting Measures
Fire:
Not considered to be a
fire hazard.
Explosion:
Not
considered to be an explosion hazard.
Fire Extinguishing Media:
Use any means suitable for
extinguishing surrounding fire.
Special
Information:
In the event of a fire,
wear full protective clothing and NIOSH-approved
self-contained breathing apparatus
with
full face piece operated in the pressure demand or
other positive pressure mode.
6. Accidental Release
Measures
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. US Regulations
(CERCLA) require reporting spills and releases to
soil, water and air in
excess of
reportable quantities. The toll free number for
the US Coast Guard National Response Center is
(800) 424-8802.
7. Handling and Storage
Keep
in a tightly closed container, stored in a cool,
dry, ventilated area. Protect against physical
damage.
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:
Trisodium
phosphate:
-AIHA Workplace
Environmental Exposure Limit:
5 mg/m3
(15-minute STEL)
Ventilation System:
A system of local and/or general
exhaust is recommended to keep employee exposures
below the Airborne
Exposure Limits.
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):
If the exposure limit is exceeded and
engineering controls are not feasible, a full face
piece respirator with
high efficiency
particulate filter (NIOSH type N100 filter) 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. If oil particles
(e.g. lubricants, cutting fluids, glycerine, etc.)
are present, use a NIOSH
type Ror P
filter. For emergencies or instances where the
exposure levels are not known, use a full-face
piece
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.
