is a slightly lighter than air, flammable, colorless gas, with a distinct garlic–like odor. When mixed with Oxygen, it gives flame temperatures up to 3100°C (5.612°F). It is spontaneously combustible in air, at pressures above 2 BAR (30psi).
• Boiling point: –83.8°C (–118.8°F).
• Trade name: Acetylene.

Precautions

• Although it is non–toxic, acetylene is anesthetic if inhaled. Acetylene concentrations higher than 20% can cause unconsciousness, so areas of storage and use should always be well ventilated.

• Acetylene is explosive when mixed with air, however large or small the quantity. Explosive reactions may occur on ignition. It reacts explosively with halogens and halogenated compounds and will form an explosive compound with copper; therefore, equipment containing more than 65% copper should not be used. Acetylene is also not compatible with mercury or silver.

• Storage temperature should be kept under 54°C (130°F).

• For cutting and welding, safety goggles or glasses must always be used.

Tango Supplier offers a great variety, all purpose Calibration Gases. They are efficiently used for calibration of gas detection systems. TANGO guarantees the mixture components for all its Calibration Gases available:

Nitrogen (N2) is a colorless, tasteless, and an odorless inert gas, slightly lighter than air; it is used for purging tanks and pipelines and for the removal of moisture from refrigeration systems. It does not react with any substance or gas and is non toxic. Nitrogen is also non combustible and does not burn nor does it affect the respiratory system. It is slightly soluble in water and most other liquids and is a poor conductor of heat and electricity. It can also be used for providing a safe blanket for cargo, preventing reactions with Oxygen.
• Trade name: Nitrogen.

Precautions

• As with Argon, Nitrogen displaces Oxygen in non ventilated areas, this can cause asphyxiation and in prolonged cases, even death. Therefore, areas of storage should always be well ventilated and have the possibility for a fast evacuation for your staff.

• Extra precautions should be taken to avoid the possibility of leakages.

• Storage temperature should be kept under 45°C (113°F).

OXYGEN (O2) is a gas heavier than air, colorless, odorless and taste free. Although it is a non–flammable natural born gas oxygen, can still enforce combustion. • Boiling point: –182.97°C (–297.35°F). • Trade name: Oxygen.

Precautions

• Grease, oil or other flammable materials, may react violently on contact with oxygen under pressure. Therefore, they must never mix with any welding or cutting equipment. Moreover, oxygen must never be used as a substitute for compressed air in pneumatic equipment, since this type of equipment contains flammable lubricants.

• Storage temperature should be kept under 54°C (130°F). Moreover, areas of storage should be dry and well ventilated.

• Breathing high concentrations of O2, causes symptoms of hyperoxia, which in some cases may be fatal.

• For cutting and welding, safety goggles or glasses must be used.
