How can you find a MSDS?

To locate the correct MSDS, always use the product identifier, not a shortened name that may be used at your workplace. Check that the name of the manufacturer and/or supplier matches the label as well. The MSDS and label may also display other identification, such as a product code or catalog number.

What is compressed gas nos?

(Not Otherwise Specified): used as the last qualifier in the definition of a class or category, as a punctuation period that restricts further narrowing of that specification, such as in the UN number for the transportation of dangerous goods; e.g., UN1956 is defined as “Compressed Gas, N.O.S.”; whether it is flammable …

Is compressed nitrogen dangerous?

Inert gases, such as argon, helium, neon and nitrogen, are not toxic and do not burn or explode. Yet they can cause injury or death if they are present in sufficiently high concentrations. They can displace enough air to reduce oxygen levels.

When should you look up a chemical’s MSDS?

A manufacturer, importer, supplier, or employer shall check the accuracy of a Safety Data Sheet (SDS) based on the actual circumstances and update it as needed. A Safety Data Sheet shall be reviewed at least every 3 years. Records of SDS updates such as content, date, and version revision, shall be kept for 3 years.

What is UN1956 used for?

Guide #126 MIG welding – short circuit transfer – general purpose gas UN1956 for mild steel and auto body metal. 1/ When ordering mixes add the MIXTURE DASH NUMBER (or letters) to the mix part number found on the High Pressure Gas and Cylinder Identification Chart.

What are the dangers of compressed gas?

Compressed Gases

• Dangers from Compressed Gases. Compressed gas cylinders are common in the laboratory environment.
• Asphyxiation. Compressed gases can displace oxygen causing injury or death.
• Fire and Explosion.
• Chemical Reaction.
• Poisoning.
• High Pressure.
• Improper Handling.
• Penetrating Skin.

Is breathing in nitrogen bad for you?

Nitrogen is an inert gas — meaning it doesn’t chemically react with other gases — and it isn’t toxic. But breathing pure nitrogen is deadly. That’s because the gas displaces oxygen in the lungs. Unconsciousness can occur within one or two breaths, according to the U.S. Chemical Safety and Hazard Investigation Board.

Is it dangerous to breathe nitrogen?

Because 78 percent of the air we breathe is nitrogen gas, many people assume that nitrogen is not harmful. However, nitrogen is safe to breathe only when mixed with the appropriate amount of oxygen. A nitrogenenriched environment, which depletes oxygen, can be detected only with special instruments.

Is nitrogen gas a hazardous material?

Nitrogen is a colorless gas or a liquid under pressure. It is the main component of air. It has many medical and industrial uses including the quick freezing of food. * Nitrogen is on the Hazardous Substance List because it is cited by ACGIH, DOT and NFPA.

Is nitrogen reactive or nonreactive?

Nitrogen is a rather unreactive element, and the reason is that the N≡N bond energy is 946 kJ mol−1. This lack of reactivity is somewhat unlike other nonmetals given the position of the atom in the periodic table and the fact that nitrogen is a nonmetal having an electronegativity of 3.0 (the third highest value).
