2. BİLEŞİMİ HAKKINDA BİLGİLER

3. HAZARDS IDENTIFICATION

It is a colorless, odorless, non-toxic, inert, non-flammable, compressed gas in steel tubes under high pressure. Tubes should be used and stored below 45 oC. Argon is not toxic; but at high concentrations it behaves as a simple suffocating gas. It is 1.38 times lighter than air.

4. FIRST AID MEASURES

Inhalation: The casualty should be taken to a clean area immediately, minimizing the risk to the worker. There should be no obstructions to the air intake. If respiratory failure is present or has stopped, give CPR immediately. The casualty should be kept warm and comfortable. Subsequent treatment should be symptomatic and supportive care.

5. FIRE FIGHTING METHODS

Suitable Extinguishing Media / Extinguishing Method : Argon is not flammable. Extinguishing media suitable for the ignited material is used. Argon in the gas phase is stored compressed in high pressure steel tubes. In case of fire, the increase in pressure along with the increase in temperature can cause the tube to rupture violently. Cylinders exposed to fire should be cooled with water from a safe distance during and after combustion. In order to prevent gas compression, water should not be kept on the valve part of the tube. Otherwise, gas may collect and explosion may occur.

Unsuitable Extinguishing Media / Method : None.
Harmful Substances Resulting from Combustion: None.
Protective Equipment in Fire Fighting: Fire fighting team should wear respiratory protection device and flame resistant clothing.
6. MEASURES TO BE TAKEN AGAINST ACCIDENTAL RELEASE OF GAS
Personal Precautions: The area where the product is spread should be evacuated immediately. Positive pressure breathing apparatus should be used at the entrances to the area where the product is spread, until the ambient atmosphere is completely safe.

Measures to be Taken in the Environment: The gas leaking tube should be taken to a safe area and the company should be called before any repairs are made on it.

Cleaning methods : The affected area should be ventilated.

7. HANDLING AND STORAGE

Usage : While the cylinders are being transported within the facility, they should be transported with their valves closed and their caps attached. During transportation, the tubes should not be tilted, preferably in an upright position, on a trolley and should be transported tied up. Tubes should not be transported by lifting from their cap and valve. Magnet rope or chain should be used to lift the tubes, the tubes must not fall or collide with each other. Cylinders brought to the place of use should be used upright, and the correct gas should be checked from the label on the tube. The cover should be removed and the valve threads should be checked. Appropriate pressure reducer (regulator) and equipment should be installed. The valve should never be lubricated and open slowly. Gas leaks should be checked with an appropriate method (soap foam, leak detection lotion). Before putting the tube into use, care should be taken that there is no feedback to the system. Direct naked flame or electrical heating devices should never be used to pressurize a cylinder. The tube should never be exposed to a temperature above 45 °C. Before the gas in the cylinder is completely exhausted, the valve of the cylinder should be closed without difficulty and its cap should be attached. A blank label should be affixed to it and taken to the warehouse. Tubes chock, roller, support etc. should not be used for such purposes.

Storage : Cylinders should be stored in a well-ventilated area protected against corrosion and harsh weather. During storage, precautions should be taken so that the temperature of the tube does not go below -40 degrees Celsius and does not rise above 45 °C. Cylinders should be kept free from the risk of fire and away from heaters/igniters. The storage area should be kept clean and only authorized personnel should be able to enter. The storage area should be marked with appropriate hazard warning signs. Stored cylinders should be kept in such a way that they will not tip over or roll over. Tube valves must be tightly closed and their protective caps must be in place. Full and empty tubes should be stored separately, and full tubes should be adjusted so that old stock is used first.

Special Uses: It is known that there are special uses other than those mentioned above. Users should adhere to the applicable methods and procedures, gaining knowledge from the literature on these particular applications.

8. EXPOSURE CONTROL / PERSONAL PROTECTION

Occupational Exposure Limit: Ventilation should be done to prevent the oxygen level in the air from falling below 19.5%.

Occupational Exposure Controls : Argon is not toxic, but in high concentration it acts as a simple suffocating gas. It should not be deliberately inhaled.

Protection of the Respiratory System: If the concentration in the air is higher than the oxygen concentration required for respiration, tube respirators should be used.

Hand Protection: Sturdy work gloves should be used.

Eye Protection: Face shield and eye mask should be used.

Skin Protection: Appropriate work clothes and steel-toed shoes should be used.

Environmental Exposure Controls: There is no harmful effect on the environment in terms of its chemical properties.
