The oxidizing agent is air with an oxygen content of 20.95 % by volume. In the data base it is usually not specified as mixture component. Exceptions are highlighted.
Pressure values are absolute, not gauge pressures.
Impurities can strongly influence characteristic safety data, particulary if the properties of the impurity considerably deviate from the respective properties of the pure substance.
Safety characteristics are only displayed if evaluated data are available.
Values can be cited by using the UTI number of the table (Uniform Table Identifier).
