An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
Airgas, an Air Liquide company, is an American supplier of industrial, medical and specialty gases (delivered in packaged or cylinder form), as well as hardgoods and related products; one of the largest U.S. suppliers of safety products; and a leading U.S. supplier of ammonia products and process chemicals.
Consider the first triangular diagram below, which shows all possible mixtures of methane, oxygen and nitrogen. Air is a mixture of about 21 volume percent oxygen, and 79 volume percent inerts (nitrogen). Any mixture of methane and air will therefore lie on the straight line between pure methane and pure air – this is shown as the blue air-line.
Liquid nitrogen is a compact and readily transported source of dry nitrogen gas, as it does not require pressurization. Further, its ability to maintain temperatures far below the freezing point of water, specific heat of 1040 J ⋅kg -1 ⋅K -1 and heat of vaporization of 200 kJ⋅kg -1 makes it extremely useful in a wide range of applications ...
Because it is a computer-based system, IMDS highlights hazardous and controlled substances by comparing entered data with regulatory-originated lists of prohibited substances (GADSL, [3] REACH, ELV, etc...). Hence OEMs can trace hazardous substances back to the individual part and work with suppliers to reduce, control, or eliminate the hazard.
For example, if a gas mixture such as air is passed under pressure through a vessel containing an adsorbent bed of zeolite that attracts nitrogen more strongly than oxygen, a fraction of nitrogen will stay in the bed, and the gas exiting the vessel will be richer in oxygen than the mixture entering. When the bed reaches the limit of its ...
The concentration of inert gases, such as nitrogen and helium, are planned and checked to avoid nitrogen narcosis and decompression sickness. Methods used include batch mixing by partial pressure or by mass fraction, and continuous blending processes. Completed blends are analysed for composition for the safety of the user.
An extinguishing system which is primarily based on inert gases, such as CO 2 or nitrogen, in enclosed spaces presents a risk of suffocation. [3] Some incidents have occurred where individuals in these spaces have been killed by inert gas release. When installed according to fire codes the systems have an excellent safety record.
