Particle moves free and weak.
Can be compress because the density is low.
Collision frequency depends on the density of gas.
Shape and volume based on container.
Move randomly at all temperature.

POTENTIAL OF HAZARD
Potential Acute Health Effects:
Eye contact (irritant), inhalation, skin contact (irritant, permeator), of
ingestion. . Inflammation of the eye is characterized by redness,watering, and itching.
Potential Chronic Health Effects:
Classified Reproductive system/toxin/female. The substance is toxic to
blood, bone marrow, central nervous system (CNS). The substancemay be toxic to liver, Urinary System. Repeated or prolonged exposure
to the substance can produce target organs damage.

HOW TO CONTROL ? Engineering Controls:
Provide exhaust ventilation or other engineering controls to keep the
airborne concentrations of vapors below their respective threshold limit
value. Ensure that eyewash stations and safety showers are proximal to
the work-station location.
Personal Protection Splash goggles. Lab coat. Vapor respirator. Be sure to use an
approved/certified respirator or equivalent. Gloves.
HOW TO STORAGE? Store in a segregated and approved area. Keep container in a cool, well-
ventilated area. Keep container tightly closed and sealed until ready for
use. Avoid all possible sources of ignition (spark or flame).

Ammonia gas
POTENTIAL OF HAZARD
Inhalation: VERY TOXIC, can cause death.
Skin Contact: CORROSIVE. The gas irritates or burns the skin.
Eye Contact: CORROSIVE. The gas irritates or burns the eyes.
Ingestion: Not a relevant route of exposure (gas)
Effects of Long-Term (Chronic) Exposure: May harm the respiratory system. Can
irritate and inflame the airways.
Carcinogenicity: Not known to cause cancer.
Teratogenicity / Embryo toxicity: Not known to harm the unbornchild.
Reproductive Toxicity: Not known to be a reproductive hazard.
Mutagenicity: Not known to be a mutagen. Conclusions cannot be
drawn from the limited studies available.

HOW TO CONTROL? Engineering Controls
Use a local exhaust ventilation and enclosure, if necessary, to control
amount in the air. It may be necessary to use stringent control measuressuch as process enclosure to prevent product release into the workplace.
Personal Protective Equipment Eye/Face Protection: Wear chemical safety goggles. A face shield may also
be necessary. Skin Protection: Wear chemical protective clothing e.g. gloves, aprons,
boots.
Respiratory Protection: Up to 250 ppm wear a NIOSH approved air-purifying respirator with an appropriate cartridge
HOW TO STORAGE? Store in an area that is cool, dry, out of direct sunlight and away from
heat and ignition sources, separate from incompatible materials, secureand separate from work areas, an approved, fire-resistant area. Store inthe original, labeled, shipping container.

EMERGENCY OVERVIEW:This is a greenish,
NITROGEN gas
POTENTIAL OF HAZARD
This is a greenish, non-flammable gas mixture with a distinct, irritating odor of
Chlorine.
Releases of this gas mixture can cause a hazard of asphyxiation by
displacement of oxygen.
This gas mixture presents no hazard of flammability or reactivity
Flame or high temperature impinging on a localized area of the cylinder
can cause cylinder to rupture violently or explosively.
Inhalation of this gas may cause, discomfort to the nose and throat.
It was also a result of the inhalation of chlorine, it can also make us cough,
shortness of breath, sore throat and lung problems which can be fatal.

HOW TO CONTROL?
VENTILATION AND ENGINEERING
RESPIRATORY PROTECTION EYE PROTECTION
HAND PROTECTION
BODY PROTECTION
HOW TO STORE? Cylinders should be stored upright and be firmly secured to prevent falling orbeing knocked-over.
Cylinders should be stored in dry, well-ventilated areas away from sources of
heat or ignition.
Do not allow the area where cylinders are stored to exceed 52c(125F).
