Potential Health Effects
----------------------------------
I
nhalation:Causes irritation to the respiratory tract. Symptoms may include coughing,
shortness of breath.
Ingestion:
Causes irritation to the gastrointestinal tract. Symptoms may include nausea,
vomiting and diarrhea.
Skin Contact:
Causes irritation to skin. Symptoms include redness, itching, and pain.
Eye Contact:
Causes irritation, redness, and pain.
Chronic Exposure:
No information found.
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:
Induce vomiting immediately as directed by medical personnel. Never give
anything by mouth to an unconscious person. Get medical attention.
Skin Contact:
Immediately flush skin with plenty of 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 upper
and lower eyelids occasionally. Get medical attention.
5. Fire Fighting Measures
Fire:
Not considered to be a fire hazard.
At fire temperatures ammonium chloride begins to corrode metals and may
dissociate into ammonia and hydrogen chloride. Mixtures of about 16% to 25%
(by volume) ammonia gas in air are flammable.
Explosion:
Not considered to be an explosion hazard.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire. Water spray may
be used to keep fire exposed containers cool.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. Protect from physical damage. Store in a
cool, dry, ventilated area away from sources of heat, moisture and
incompatibilities. 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:
Ammonium chloride:
-ACGIH Threshold Limit Value (TLV):
10 mg/m3 (TWA); 20 mg/m3 (STEL) Fume
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
half facepiece particulate respirator (NIOSH type N95 or better filters) 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 particulate respirator (NIOSH type N100
filters) 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 R or P filter. For emergencies or
instances where the exposure levels are not known, use a full-facepiece
positive-pressure, air-supplied respirator. WARNING: Air-purifying respiratorsdo 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.

10. Stability and Reactivity
Stability:
Stable under ordinary conditions of use and storage.
Hazardous Decomposition Products:
Involvement in a fire causes decomposition to form hydrogen chloride and
ammonia.
Hazardous Polymerization:
Will not occur.
Incompatibilities:
Concentrated acids, strong bases, silver salts, potassium chlorate, ammonium
nitrate, bromine trifluoride and iodine heptafluoride. Ammonium chloride reacts
explosively with potassium chlorate or bromine trifluoride, and violently with
bromide pentafluoride, ammonium compounds, nitrates, and iodine
heptafluoride. Explosive nitrogen trichloride may result from reaction of
ammonium chloride and hydrogen cyanide.
Conditions to Avoid:
Heat, moisture, incompatibles.
