also
known as anhydrous ammonia is a colorless liquid with a strong pungent odor
Ammonia
as an important chemical raw material, for transport and storage facilities,
gaseous ammonia is usually obtained by pressurized liquid
ammonia or cooling
Multi-pressure
liquid ammonia storage in cylinders or steel tank, and cannot coexist
with acetaldehyde, acrolein, boron and other substances
Application:
widely
used in industry, corrosive and volatile
Precaution:
Irritating ammonia is
reliable harmful concentration alarm signal. However, due to olfactory fatigue
after long-term exposure to low concentrations of ammonia will be difficult to
detect. Mild inhalation of ammonia poisoning manifestations of rhinitis, pharyngitis,
tracheitis, bronchitis, acute inhalation of ammonia poisoning occurs by many as
the pipe rupture accident, caused by a valve burst. Acute ammonia poisoning
mainly for respiratory tract irritation and burns. Severe inhalation poisoning
can occur laryngeal edema, glottis and respiratory mucosa narrow loss, can
cause airway obstruction, causing suffocation.
The low concentrations of ammonia in the wet skin can rapidly produce a
stimulating effect. Moist skin or eye exposure to high concentrations
of ammonia can cause severe chemical burns. High concentrations of vapor has a
strong irritant to the eyes, can cause pain and burns, cause significant
inflammation and edema may occur, epithelial tissue damage, corneal opacity and
iris inflammation.
