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.

Benzene GAs

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).
