In addition, it covers both new and
existing gas pipework installation
with a nominal OP not exceeding 2bar
installed downstream of the primary
meter installation in industrial
and commercial premises. It also
covers controls and associated gas
appliances, including appliance
connections and pipework.

Atmospheres Regulations (DSEAR)
came into force in December 2002 and
the requirements for the preparation
of risk assessments to determine any
hazardous area classification first came
into force on 30 June 2003.
