Purpose
The purpose of this directive is to ensure
• that injuries, accidents and undesired incidents do not occur while a job
is being performed
• that simultaneous activities do not cause any danger
• the operational safety of the task performed

Domain
• This directive applies to all BP-operated installations and contracted
installations on the Norwegian continental shelf.

• Contractors of contracted installations who have a system that satisfies
the requirements in this directive, may use their own system provided
this has been clarified upon implementation

• Onshore facilities or projects where BP Norge have a particular
responsibility and which are assessed being part of the petroleum
activities

Safety measures for hot work class b
• Before hot work class B in classified areas can start, the area technician
must measure the concentration of flammable gases in the area and
ensure that the concentration is less than 1% LEL
• Before and during hot work class B, the area technician shall
o evaluate potential leakage sources, and prevent spills of oil/gas
in the area
o inspect the work site
o ensure that all safety systems in the area are operative, alternatively
that compensating measures have been implemented
• Before and during hot work class B the performing technican shall
o ensure that there is a gas meter on site so that the work
can be stopped if gas is detected
o ensure that a suitable fire extinguisher is easily accessible
o ensure that any flammable material is removed/covered
o be familiar with the procedures/checklists for the relevant operation
o ensure that other measures described in the work permit (WP)
have been implemented

Execution of gas measurement
• For hot work class B in classified areas, the area technician shall
measure the content of hydrocarbon gas at potential leakage points -
flanges, seals, outlets, etc. - in the area around the work site,
immediately before the work starts
• For hot work class B in classified areas where continuous gas
measurement is used, the area technician shall evaluate the number
and location of the gas meters based on potential leakage points and
draught.

8. dISCOnnECTIOn OF SAFETY SYSTEmS
Introduction
• Disconnection of safety systems includes all isolation and
disconnection of safety systems, including maintenance and
work as described under Safety measures

Planning
• Disconnection of safety systems or part of these shall be planned so
that they are of the least possible scope and shortest possible duration,
and they must be reinstated as soon as possible after work is complete.
This should be documented as SORA (Safety Override Risk Assessment
form) in the e-logbook and approved by the area autority (OTL-D)
• Consequences and risks must always be assessed when safety
systems are disconnected. Disconnection must always be evaluated
in relation to all activities, and compensating measures must be
implemented in order to maintain safety barriers

Approval
Disconnection and isolation of safety systems requires
• An approved isolation confirmation certificate
• An approve work permit level 1

HSE dIrECTIVE 1 - WOrk PErmITS
ATTACHmEnTS

Exceptions for this approval are the following but there is still a
requirement for planning (ref procedure 1.70.124)

• disconnection (inhibiting) of fire and gas detectors that is necessary
in order to carry out other work already governed by an approved work
permit. The precondition is that personnel are present in the field
• routine testing of fire and gas and emergency shut down systems
when personnel are present in the field and in the CCR, which requires
an approve work permit level 2
• brief disconnection of safety switches in the process shutdown system
carried out by the area technician which does not require a work pemit
or isolation confirmation certificate
• brief disconnection of safety switches in the process shutdown system
carried out by the CCR technician in connection with operational needs
which does not require a work pemit or isolation confirmation certificate
• setting the inergen system in manual when personnel are entering
turbine hoods required this is covered by a approved instruction

Duration
• When safety systems are disconnected, the estimated duration must
be noted on the isolation confirmation certificate. If the equipment
cannot be restored by the stated time, a new isolation confirmation
certificate must be prepared

Safety measures for disconnection of safety system
• The equipment must be blinded, locked, labelled and documented in
the isolation confirmation certificate.
• Compensating measures shall be implemented (e.g. use of safety
guard in the area, deployment of extra fire extinguishing equipment/
detection equipment/ communication equipment, use of alternative
life-saving equipment, etc.)
• The performing technician must be familiar with procedures, risks and
safety measures when disconnecting the safety systems
• The work must be coordinated with the CCR and/or the area technician

Overview
• The CCR technician shall record all incidents of connection and
disconnection of safety systems. This shall be done with SOD (Safety
Defete Override)-registration in the e-logbook
• The HSE function (safety officer) shall maintain a constant overview of
all safety systems that are disconnected by using an ICC
