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 lower and upper eyelids occasionally. Get
medical attention immediately.
Note to Physician: -.
5. Fire
Fighting Measures
Flammability of the Product: The product is not flammable.
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.
Auto-Ignition Temperature: NA.
Flash Points: NA.
Flammable Limits: NA.
Products of Combustion: It emits toxic oxides of carbon and
oxides of nitrogen when heated to decomposition.
Fire: The product is not flammable.
Explosion: Slightly explosive in presence of heat.
Fire Extinguishing Media: Water spray. Use means suitable for
extinguishing surrounding fire. 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
face piece operated in the pressure demand or other positive pressure
mode. At high temperatures or when moistened under fire conditions, it
may produce toxic or irritating fumes.
6.
Accidental Release Measures
Small Spill: Avoid dust formation. Avoid breathing dust. Ensure adequate
ventilation. Use appropriate tools to put the spilled solid in a convenient
waste disposal container. Finish cleaning by spreading water on the contaminated
surface and dispose of according to local and regional authority requirements.
Large Spill: Do not let the product enter drains. Use a shovel to put the
material into a convenient waste disposal container. Finish cleaning by
spreading water on the contaminated surface and allow evacuating through the
sanitary system.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
Do not breathe dust. Wear suitable protective clothing. In case of insufficient
ventilation, wear suitable respiratory equipment.
Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Wash
hands thoroughly after handling. Provide appropriate exhaust ventilation at
places where dust is formed. If you feel unwell, seek medical attention.
Keep Zinc ammonium chloride in a tightly closed container, stored in a cool,
dry, ventilated area. Protect against physical damage or contact with oxidizing
material and combustible substances.Zinc Chloride is a Toxic Chemical under Section 313 of Title III/SARA, and 40
CFR Part 372.
Ammonium Salts Generate Ammonia in Water. For SARA 313 Requirements, 10% of the
Total ammonia present in aqueous ammonia solutions is reportable.

Exposure Controls/Personal Protection
Airborne Exposure Limits:---- For Ammonium Chloride:

ACGIH: |
10 mg/m3 TWA
(fume)
20 mg/m3 STEL
(fume) |
|
OSHA: |
10 mg/m3 TWA
20 mg/m3 STEL |
|
NIOSH: |
10 mg/m3 TWA
(fume)
20 mg/m3 STEL
(fume) |
---- For Zinc Chloride:
|
ACGIH: |
1 mg/m3 TWA (fume)
2 mg/m3 STEL (fume) |
|
OSHA: |
1 mg/m3 TWA (fume)
2 mg/m3 STEL (fume) |
|
NIOSH: |
1 mg/m3 TWA (fume)
2 mg/m3 STEL (fume) |
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.
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 may be worn. For emergencies or
instances where the exposure levels are not known, use a full-face
positive-pressure, air-supplied respirator.
Skin Protection: Wear protective gloves and clean body-covering
clothing.
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: Maintain good housekeeping in work area.
Dust deposits on floors and other surfaces may pick up moisture and
cause the surfaces to become slippery and present safety hazards. Handle
in accordance with good industrial hygiene and safety practice. Wash
hands after handling.

Stability and Reactivity
Stability: Zinc
ammonium chloride is stable under ordinary conditions of use and
storage. The material is delinquent and should be stored in tightly
closed containers.
Hazardous Decomposition Products: Involvement in a fire causes
decomposition to form hydrogen chloride and ammonia.

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: Moisture, Heat, Incompatibles.11.
