Safety Instructions

Reducing risk by being properly informed

The potential hazards of dealing with gases can be held under control when products are handled correctly, their properties are understood and appropriate packaging is provided. Our safety instructions contain detailed information on a range of topics including oxygen deficiency, oxygen enrichment, handling acetylene, flammable gases, liquefied gases, toxic gases, gases under pressure, chlorine gas cylinders and oxygen pressure regulators. They also tell you how to store and transport gas cylinders safely.

Transport instructions

Transporting gases safely and in compliance with the relevant regulations

The European Agreement Concerning the International Carriage of Dangerous Goods (ADR) governs the international transportation of hazardous materials, including gas. The potential hazards of transporting gas can be held under control if products are handled correctly, their properties are understood and appropriate packaging is provided.

Our transport instructions contain detailed information on a range of topics relating to the safe transport of gases. Linde offers a timely and safe delivery of products. If you like, all the way to the point of use in your facility.

Material safety data sheets (MSDS)

Helping you find the safety data sheets you need

Our safety data sheets contain all the important facts and safety recommendations for handling gases. Safety data sheets are of central importance for your safety. They serve the user of gases and gas mixtures as a source of information and form the basis for instructions on appropriate protective measures. You can download our safety data sheets via the link below.

Safety glossary

Guiding you through the maze of safety terms

We have compiled a glossary of safety terms to help you understand more about safety issues when dealing with gases:

Term	Description
Autoignition temperature	The lowest temperature at which a material will ignite and sustain combustion in the absence of a spark or flame.
Corrosive	A substance that erodes and deteriorates materials upon contact (this may include skin tissue).
Flame propagation	The spread of a flame outward from the source of ignition through a combustible mixture.
Flammable gas	Any gas that will ignite easily and burn rapidly.
Flammable limits	Flammable limits define the minimum and maximum concentration of vapour/gas in air or oxygen needed to make the mixture combustible. They are usually expressed as a percentage of gas or vapour in air. A change in temperature or pressure may vary the flammable limits of a gas.
Flash point	The lowest temperature at which a liquid will vaporise to form an ignitable mixture in air.
Frangible disk	Also known as a "burst disk", this metal safety device is designed to burst and allow gas to escape within predetermined pressure limits. It is intended to prevent devices from rupturing and functions in much the same way as a safety relief valve, except that it cannot be resealed.
Fusible plug	A fusible plug is a safety valve which has a core of metal with a low melting point. This core melts once a predetermined temperature is reached. It cannot be resealed.
Inert	Gases that do not react with other materials at ordinary temperature and pressure are classified as inert. They do not represent a hazard unless they are released in a confined space where they can displace oxygen and create an asphyxiating atmosphere. Adequate ventilation and monitoring of oxygen content in confined spaces minimises the risk of asphyxiation.
LEL	Abbreviation for Lower Explosive Limit. The lowest percentage of a gas in air capable of forming a flammable mixture.
Liquefied compressed gas	A gas which, under charged pressure, is partially liquid at a temperature of 70oF.
MSDS	Abbreviation for Material Safety Data Sheets. These documents describe the hazards of each gas or material. They also provide information on the safe handling of the gas as well as emergency and first aid procedures.
Oxidant	Gases that do not burn but support combustion are classified as oxidants.
Pressure or safety relief devices	Devices designed to prevent cylinders under a normal charge from rupturing when they are inadvertently exposed to fire or intense heat.
Pressure relief valve	A pressure relief device which is designed to open and close at a predetermined pressure levels.
Pyrophoric substance	A substance that will ignite in air at or below room temperature without requiring additional heat, shock or friction.
Threshold limit value - ceiling limit - (TLV-C)	The maximum concentration of a substance in air that should never be exceeded, not even instantaneously.
Threshold limit value - time weighted average - (TLV-TWA)	The average concentration limit of a substance in the air to which a worker can be exposed day after day for a working lifetime, without adverse effect. It is based on an eight-hour workday or 40-hour workweek.
Toxicity	The ability of a chemical or gas to produce injury once it reaches a susceptible site in or on the body.
