What Is an Oxidizing Gas?

An oxidizing gas is any gas that can cause or contribute to the combustion of other materials more than air does, generally by providing oxygen or other oxidizing substances. According to OSHA, these gases demonstrate an oxidizing power greater than 23.5% as determined by standardized testing methods. In this guide, we’ll explore the key characteristics …

What Is a Corrosive Gas?

A corrosive gas is a chemical substance in gaseous form that can cause visible destruction or permanent damage to living tissue, metals, and other materials through direct chemical action. These effects occur through acidic reactions, caustic reactions, and oxidation processes, making them some of the most hazardous materials in industrial settings. In this guide, we’ll …

What Is a Pyrophoric Gas?

A pyrophoric gas is a chemical substance in gaseous form that ignites spontaneously when exposed to air at temperatures of 130°F (54.4°C) or below, without requiring an external ignition source. These gases represent one of the most hazardous categories of industrial materials due to their unpredictable ignition behavior and extreme reactivity with atmospheric oxygen. In …

How to Store Dry Ice

Storing dry ice safely requires specialized insulated containers with proper venting, adequate ventilation systems, and strict safety protocols to prevent carbon dioxide buildup. The extreme temperature of -78.5°C (-109.3°F) and continuous sublimation process create unique storage challenges – so container selection, atmospheric monitoring, and personnel protection are all very important. In this guide, we’ll explore …

Working in Confined Spaces: Managing Atmospheric Hazards

Confined spaces are where essential tasks happen—maintaining pipelines, cleaning tanks, repairing utility lines underground. But the conditions can be some of the most hazardous on any job site. According to the Bureau of Labor Statistics, 1,030 workers died from occupational injuries involving a confined space from 2011 to 2018. Over that period, 126 workers died …

How to Store CO₂

The best way to store CO₂ is upright in a cool, dry, well-ventilated area below 70°F, with tanks and cylinders secured by chains or straps to prevent tipping. Whether you’re managing a single cylinder or an entire inventory, proper storage prevents dangerous pressure buildup, product loss, and safety incidents. WestAir provides carbon dioxide to its …

Is Nitrous Oxide Flammable?

Nitrous oxide (N₂O) is not flammable on its own, but it acts as a powerful oxidizer that supports combustion and can create explosive conditions when mixed with flammable materials. This makes it more dangerous than some other non-flammable gases. WestAir supplies nitrous oxide across California and Arizona. Why Is Nitrous Oxide Dangerous Despite Being Non-Flammable? …

How Much Nitrogen Does Corn Need?

Corn typically needs 180-250 pounds of nitrogen per acre, or about 1 pound per bushel of expected yield. Your exact rate depends on yield goals, soil organic matter, previous crops, and manure history. WestAir supplies gas for crop farming across California and Arizona. What Factors Determine How Much Nitrogen Your Corn Needs? Your corn’s nitrogen …

What Happens If You MIG Weld Without Gas?

MIG welding without gas causes poor weld quality due to oxidation and contamination. The absence of shielding gas allows air to reach the weld, creating porosity, weak joints, and excessive spatter. Flux-cored wire is the primary substitute for shielding gas. It offers a viable gasless alternative by generating its own protective shielding. In this guide, …

How Cold is Liquid CO₂?

The temperature range of liquid CO₂ is  between -56.6°C and 31.1°C, but only under specific pressure conditions above 5.11 atmospheres. Unlike water, which remains liquid at atmospheric pressure across a wide temperature spectrum, liquid carbon dioxide requires carefully controlled pressure and temperature to prevent it from turning into solid dry ice or gas. In this …

What Is an Inert Gas?

An inert gas is a non-reactive gas that doesn’t readily undergo chemical reactions under normal conditions because of its stable electron configuration. This non-reactivity makes inert gases invaluable across applications. In this article, you’ll learn exactly what makes a gas inert. We’ll also cover the most common inert gases used in different industries and their …

Why Is Nitrogen Used for Pressure Testing?

Nitrogen is used for pressure testing because of its inert chemical properties, safety characteristics, and cost-effectiveness compared to other testing methods. This combination of benefits makes nitrogen the preferred choice across industries from oil and gas to HVAC systems. In this guide, we’ll explore the key reasons why nitrogen dominates pressure testing applications and how …
