Lower-Tier Production Installation
Definition(s)
Lower-Tier Production Installation
Lower-tier production installation means an onshore production installation where petroleum is or is intended to be produced, and in respect of which— (a) the actual or expected average oil production over any continuous 12-month period is below 820 barrels per day; and (b) the actual or expected average net gas production over any continuous 12-month period is below 15 million standard cubic feet of gas per day; and (c) the amount of liquefied flammable gases (including liquefied petroleum gas and natural gas) that is or is likely to be at the installation does not, at any time, exceed 50 tonnes.

Definition(s)
“What If?” Analyses
These consist of a structured series of considered questions dealing with aspects of the design, construction and operation of an installation and determine the general consequences of any deviation from the norm.

Regulatory GuidanceTask Analysis
Definition(s)
Task Analysis
Task analysis enables the systematic examination of all occupations and tasks to establish the effectiveness of work procedures and practices and to identify hazards associated with any of the sequential steps. The process involves: • Inventory of the tasks. • Identify the critical tasks and concentrate on these. Consider such factors as: — the severity of the potential losses; — the frequency with which the task is performed; — the probability of loss when the task is performed. • Break down the work into significant steps or critical activities. • Identify what could go wrong. Consider people, equipment, materials, environment. • Is it being done the best way? Consider cost, production, quality and safety. • Develop controls: specific actions and precautions to prevent loss from occurring. • Write down the procedure: a step-by-step description of how to proceed, what to do, why, in a simple, easy-to-follow format or practice. • Put to work task instruction, skill training, etc. Documentation and followup of progress is important. Two basic approaches are: — analysis by observation and discussion; Ñ analysis by discussion alone.

Regulatory GuidanceSignificant Hazard
Definition(s)
Significant Hazard
“Significant hazard” means a hazard that is an actual or potential cause or source of: • Serious harm; or • Harm (being more than trivial) where the severity of effects on any person depend (entirely or among other things) on the extent or frequency of the person’s exposure to the hazard; or • Harm that does not usually occur, or usually is not easily detectable, until a significant time after exposure to the hazard.

Significant hazard means a hazard that is an actual or potential cause or source of— (a) serious harm; or (b) harm (being harm that is more than trivial) the severity of whose effects on any person depend (entirely or among other things) on the extent or frequency of the person’s exposure to the hazard; or (c) harm that does not usually occur, or usually is not easily detectable, until a significant time after exposure to the hazard.

Definition(s)
Safety Report
A “safety report”, sometimes referred to as a “safety case”, collates all the safety information into one document so that all persons on the installation are aware of the hazards and safety of the installation. It can also be made available to regulatory authorities as evidence of the safe operation of the installation. The report should be continually reviewed and updated. The safety report should describe: • The installation, processes and hazardous substances used; • The hazards and their control; • The consequences to people and the environment of potential major industrial accidents by means of systematic hazard analysis; • The organisation of the installation and management of its safety; • Emergency systems provided to mitigate the consequences of major industrial accidents.

Definition(s)
Reporting And Response Systems
Reporting and response systems enable information to be collected and evaluated to ensure that appropriate remedial actions are taken to maintain control.

Regulatory GuidanceReactive Monitoring Systems
Definition(s)
Reactive Monitoring Systems
Reactive monitoring systems collect and analyse information suggesting failures in health, safety and environmental performances. These require systems for reporting: • Injuries and cases of ill health; • Events, e.g. damage to property or the environment; • Events that have the potential to cause injury, illness or damage to property or the environment; • Hazards; • Weaknesses or omissions in performance standards.

Definition(s)
Principal
Party that initiates the project and ultimately pays for its design and construction- Note: 1 to entry: The principal generally specifies the technical requirements and is ultimately responsible for ensuring that safety and all other issues are addressed.
