Nitrogen is a colorless gas or liquid under pressure. It is mainly used as a refrigerant with applications in the medical field and food industry. Nitrogen is also used for tank blanketing for the transportation of other chemicals by helping reduce the potential of ignition from combustible or flammable liquids and other chemical reactions.

Unmarked cylinders used or stored in large quantities can pose many dangers. Communicate the hazards of cylinders with our Gas Cylinder Shoulder Labels to keep workers out of harm's way. Labels are pre-printed with UN number and feature pictogram depicting the class of hazard the cylinder contents pose.

Nitrogen Cycle Definition. "Nitrogen Cycle is a biogeochemical process which transforms the inert nitrogen present in the atmosphere to a more usable form for living organisms.". Furthermore, nitrogen is a key nutrient element for plants. However, the abundant nitrogen in the atmosphere cannot be used directly by plants or animals.

Oxygen - nitrogen gas mixture is a colorless odorless gas. Both oxygen and nitrogen are noncombustible; however, oxygen can accelerate the burning of a fire. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket.

Oxygen-free nitrogen is defined as gaseous nitrogen-containing no more than 0.5 parts per million of oxygen. OFN gas is typically maintained at 99.998% purity. This grade of nitrogen gas is useful in scientific research and calibration processes where oxygen impurities might alter outcomes or cause incorrect results.

OSHA, FDA and DOT have guidelines developed for precautionary labels for use on oxygen cylinders and cryogenic vessels. These are to be used to identify the contents, warning of principal physical and health hazards, and providing appropriate precautionary information. It is the responsibility of the company(s) that fills, stores, delivers, handles and uses the gas to ensure that the label ...

Denitrification. Denitrification completes the nitrogen cycle by converting nitrate (NO 3-) back to gaseous nitrogen (N 2).Denitrifying bacteria are the agents of this process. These bacteria use nitrate instead of oxygen when obtaining energy, releasing nitrogen gas to the atmosphere.

OSHA nitrogen gas regulations require industrial employers to identify and properly label areas of high or potentially high concentrations of nitrogen gas with clearly visible warning signs. In addition to posting bold signs warning workers of potential risks of enclosed spaces, employers will need to obtain special permits for confined spaces ...

As these bacteria are aerobic, some oxygen is required for the bacteria to survive, but too much oxygen inactivates the enzyme nitrogenase that catalyses nitrogen fixation. The nitrogen molecule (N 2) is very stable and 16 molecules of ATP are needed for each molecule of nitrogen that is fixed. In the soil microorganism Klebsiella pneumoniae a ...

Dissolved oxygen, temperature, and aquatic life. Water temperture affects dissolved-oxygen concentrations in a river or water body. As the chart shows, the concentration of dissolved oxygen in surface water is affected by temperature and has both a seasonal and a daily cycle. Cold water can hold more dissolved oxygen than warm water.

Nitrogen, compressed. Nitrogen is the chemical element with the symbol N and atomic number 7. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772.
