According to § 5 (1) (d) of Act No. 174 / 1968 Coll., on State Professional Safety Supervision ("the Act '), the Czech Labour Safety Authority provides in agreement with the Czech Trade Union Council and other central bodies:
Scope
The decree sets out the obligations of the organisation and its personnel in the design, establishment, location and operation of low pressure boilers (hereinafter referred to as "boiler rooms'), in which the sum of the rated heat output of low pressure boilers (hereinafter referred to as" boilers') exceeds 50 KW.
Basic concepts
For the purposes of this decree, it shall be considered as:

2. steam with design overpressure of boilers up to and including 0,07 MPa,
3. liquid at the highest working temperature of the liquid, which does not exceed the boiling point at an excess pressure of 0,07 MPa.
It does not decide whether boilers of the same type are in one boiler room;
(b) a steam boiler of an installation in which steam of a rated excess pressure of not more than 0,07 MPa is produced by combustion of solid, liquid or gaseous fuels, where appropriate using electricity;
