  2. Safety data sheet - Wikipedia

    en.wikipedia.org/wiki/Safety_data_sheet

    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.

  3. List of highly toxic gases - Wikipedia

    en.wikipedia.org/wiki/List_of_highly_toxic_gases

    Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.

  4. Flammability diagram - Wikipedia

    en.wikipedia.org/wiki/Flammability_diagram

    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.

  5. Airgas - Wikipedia

    en.wikipedia.org/wiki/Airgas

    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.

  6. Risk and Safety Statements - Wikipedia

    en.wikipedia.org/wiki/Risk_and_Safety_Statements

    Risk and Safety Statements, also known as R/S statements, R/S numbers, R/S phrases, and R/S sentences, is a system of hazard codes and phrases for labeling dangerous chemicals and compounds. The R/S statement of a compound consists of a risk part (R) and a safety part (S), each followed by a combination of numbers.

  7. Dinitrogen tetroxide - Wikipedia

    en.wikipedia.org/wiki/Dinitrogen_tetroxide

    Dinitrogen tetroxide, commonly referred to as nitrogen tetroxide (NTO), and occasionally (usually among ex-USSR/Russian rocket engineers) as amyl, is the chemical compound N 2 O 4. It is a useful reagent in chemical synthesis.

  8. Liquid nitrogen - Wikipedia

    en.wikipedia.org/wiki/Liquid_nitrogen

    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 ...

  9. International Material Data System - Wikipedia

    en.wikipedia.org/wiki/International_Material...

    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.
