General Description. A colorless odorless gas. Noncombustible and nontoxic. Makes up the major portion of the atmosphere, but will not support life by itself. Used in food processing, in purging air conditioning and refrigeration systems, and in pressurizing aircraft tires. May cause asphyxiation by displacement of air.
Liquid Nitrogen and Argon. All users of cryogenic liquid nitrogen (LN2) and liquid argon (LAr) in laboratory settings should review this guideline. This document focuses on the use of liquid nitrogen but can be used for liquid argon because of the similarities in properties and equipment (see Appendix A for properties of these cryogenic liquids ...
Safety Gas. Although nitrogen is non-toxic, when released into an enclosed space it can displace oxygen, and therefore presents an asphyxiation hazard. This may happen with few warning symptoms, since the human carotid body is a relatively poor and slow low-oxygen (hypoxia) sensing system.

This Safety Bulletin is being issued to alert readers to the potential hazard of nitrogen asphyxiation following the November 6, 2005, fatality of two contractor maintenance workers at the Valero Energy Corporation's Delaware City, Delaware refinery. Nitrogen gas, inert under most conditions, is widely used as a barrier to prevent unwanted ...
Responsibly transporting nitrogen cylinders is essential to the safety of employees and the general public. Gas Safe recommends that any organisation transporting dangerous goods, such as nitrogen gas bottles, follows the basic legal safety regulations within ADR, including driver training, vehicle ventilation, safety equipment …
Case Study: Mix-up Nitrogen and Air A contract employee planned to use a hammer powered by air to chip residue from a furnace in an aluminum foundry. •He wore an airline respirator. •Two compressed gas lines were available, one was labeled "natural gas" and one was labeled "air". •Once the respirator was in place, the
Compressed gas is defined as any non-flammable material or mixture contained under pressure exceeding 41 psia (3 bar) at 70°F (21°C), or any flammable or poisonous material that is a gas at 70°F (21°C), stored at a pressure of 14.7 psia (1 bar) or greater. Most compressed gases will not exceed 2,000-2,640 psig (138-182 bar), though some go ...
Nitrogen is a non-flammable air gas that forms 78% of the earth's atmosphere. Valued for its inert properties in its gaseous form, nitrogen displaces air and therefore, reduces or eliminates the oxidation of materials. It is also used as an assist gas for laser cutting. Given the extremely low temperatures of its liquid state, nitrogen is an ...
Liquid Nitrogen Safety: 1 - Liquid Nitrogen Safety 2 - Page 2 3 - Page 3 4 - Page 4 HOME. General. Liquid nitrogen is inert, colorless, odorless, non-corrosive, nonflammable, and extremely cold. Nitrogen in gas form is inert except when heated to very high temperatures where it combines with some of the more active metals, such as …
Process Safety Beacon. On January 28, 2021, a liquid nitrogen leak occurred at a poultry processing plant in Gainesville, GA (1). The poultry plant had installed the liquid …
Nitrogen is an inert gas. It is colorless and odorless and can displace oxygen in a confined environment. Nitrogen is used as a purge gas in pipelines because of its inertness or unreactivity. It is also used as a blanket gas in vessels and tanks because it is inert and keeps moisture out. Every year, industrial workers are killed by nitrogen.
