Potential Health Effects
----------------------------------
Inhalation:
Dusts may irritate the respiratory tract with symptoms of coughing, and
shortness of breath.
Ingestion:
May irritate the G. I. tract. Abdominal pain, nausea, and vomiting may
occur. Ingestion of large amounts may result in diuresis and systemic
ammonia poisoning. Normal human subjects infused with ammonium acetate
exhibit flaccidity of facial muscles, tremor, generalized discomfort,
anxiety and impairment of motor performance .
Skin Contact:
May cause irritation with redness and pain.
Eye Contact:
May cause irritation, redness and pain. Splashes from solutions may produce
severe eye damage.
Chronic Exposure:
Chronic ammonium acetate ingestion may cause some liver dysfunction.
Aggravation of Pre-existing Conditions:
Persons with pre-existing liver damage may be more susceptible to the
effects of this material.
4. First Aid Measures
Inhalation:
Remove to fresh air. Get medical attention for any breathing difficulty.
Ingestion:
Induce vomiting immediately as directed by medical personnel. Never give
anything by mouth to an unconscious person. Call a physician.
Skin Contact:
In case of contact, immediately flush skin with plenty of water for at
least 15 minutes. Call a physician.
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:
As with most organic solids, fire is possible at elevated temperatures or
by contact with an ignition source.
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 facepiece 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. 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:
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 dust or mist is apparent, a
half-face dust/mist respirator may be worn. 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.
