4. First aid measures
First aid measures
First-aid measures afterinhalation:

Remove the victim to fresh air, and make him blow his nose andgargle. If necessary, get medical treatment.

First-aid measures after skincontact:

Wash the affected areas under running water, get medicaltreatment as soon as possible.

First-aid measures after eye
contact:

Wash the affected areas under running water for at least 15
minutes. Get medical treatment.

First-aid measures afteringestion:

Rinse mouth with water. Give the victim one or two glasses ofwater or milk. Do not induce vomiting. Get medical treatment assoon as possible.

Personal Protection in FirstAid and Measures:

Rescuers should wear proper protective equipment like rubber
gloves, goggles.

:

Inhalation of high concentration of ammonia gas caused pulmonary
edema, and cessation of breathing. Ammonia water has severe
irritation and corrosion of skin, and penetrates into deepertissues. Contact of high concentration of ammonia water with eyes
may lead visual disturbance.

Suitable extinguishing media:

Water, dry chemical powder, carbon dioxide, dry sand, foam

Unsuitable extinguishing media

:

None

3/6

Issue date: 8/10/2009
Revision date: 3/13/2024
Fire hazard:

Ammonia water is incombustible, but igniting air-fuel mixture is
produced by releasing ammonia vapor.

Firefighting instructions:

Move containers from fire area if it can be done without risk, if
not possible, apply water from a safe distance to cool andprotect surrounding area.
Fight fire from windward.
Dry chemical powder, carbon dioxide or dry sand should be used
for small fires. Foam extinguisher is effective for a large scale
fire.

Personal protection (Emergencyresponse):

Firefighters should wear protective equipment.

6. Accidental release measures
Personal Precautions, Protective Equipment and Emergency Procedures
General measures:

Wear proper protective equipment and avoid contact with skin andinhalation of vapor. Conduct operations from upwind and evacuate
people downwind. Remove all sources of ignition. Keep away
personnel except for authorized ones from spillage area by
stretching ropes.

:

Attention should be given to avoid discharge of spilled productinto rivers and resulting environmental damage. When diluting
spill with large amounts of water, discharge of untreatedwastewater into the environment must be avoided.

Environmental precautions
Environmental precautions

Methods and Equipment for Containment and Cleaning up
For containment:

Collect the spillage as much as possible to switable empty
container. Neutralize residue with dilute acid and then flushwith copious of water.

Prevention Measures for
Secondary Accidents:

Remove nearby sources of ignition and prepare extinguishingmedia.

Technical measures:

Wear proper protective equipment to avoid contact with skin or
inhalation of vapor. Pay attention to fire.

Precautions for safe handling:

Use with an enclosed system or a local exhaust ventilation.
Handle in a well-ventilated place. When outdoors, work is done
from the windward.

Storage conditions:

Store in a dark, cool place and tightly closed.

Material used inpackaging/containers:

Polyethylene, fluorine resin.

Aspiration hazard: Classification not possible: No classification (gas)Classification not possible (vapor)
Classification not possible (dust, mist): Causes severe skin burns
In the skin irritation test with rabbits, there is a report thatshowed the corrosion by the application of a 20% aqueous solutionof ammonium hydroxide. Since ammonium hydroxide is strongly
alkaline, and based on the description that it causes corrosion toeyes and skin, it was classified into category 1C.
: Causes serious eye damage
There are descriptions that in the application test of 1mg ofammonium hydroxide to rabbit eye, irritation was noted, and that in
the application test of 28.5% aqueous solution to rat eye,irreparable cornea damages such as nebula and opacity, andvascularization were observed. Moreover, there are descriptions
that ammonium hydroxide is strongly alkaline and corrosive to eyeand skin, and that the substance is strongly irritating to mucosa.
Thus, it was classified into category 1.
: Classification not possible: Classification not possible: Classification not possible: Classification not possible: Classification not possible: Causes damage to organs (central nervous system, respiratoryorgans)
Ammonium hydroxide shows respiratory irritation in humans andcauses severe irritation and pain of airway mucosa. The substanceis also severely corrosive to mouth, throat and stomach on oralroute. Inhalation exposure and transdermal exposure usually cause
visual damage of directly exposed sites, but severer exposurescause neurological effects, such as elevated blood ammonia levels,
seizure, coma, nonspecific diffuse brain damage, muscular weakness,
reduced deep tendon reflex and unconsciousness leading to death.
Thus, it was classified into category 1 (central nervous system,
respiratory organs).
: Classification not possible: Classification not possible
