It is important to mount the gas detection heads in areas that are most likely to first be exposed to a gas leak, or that are most representative of the gas levels in the area being monitored.Continue Reading

Gas detectors are categorized by the type of gas they detect: combustible or toxic. They are then further defined by the technology they use: catalytic and infrared sensors detect combustible gases and electrochemical and metal oxide semiconductor technologies generally detect toxic gases.Continue Reading

A fire and gas detection system warn people when smoke, fire, carbon monoxide, and other flammable and toxic gases are detected.Continue Reading

An automatic fire alarm system detects a fire in its early stages (activated by occupants of the building or by the transmission of fire alarm signals to an alarm-receiving centre), notifies the building occupants that there is a fire emergency and reports the emergency to the first responders.Continue Reading

ALARP principle is to reduce the potential risk of hazard as reasonably practicable so that the risk can be controlled.Continue Reading

The ALARP principle stands for “as low as reasonably practicable”. This principle intends to keep the risk level as low as possible, with the assurance that the ALARP evaluations are thoroughly documented.Continue Reading

Layer of Protection Analysis (LOPA) is an approach to determine the Integrity Levels (ILs) for all identified safeguarding process loops whilst Safety Integrity Level (SIL) is a measure of safety system performance, in terms of probability of failure on demand (PFD).Continue Reading

BowTieXP is the most used Risk Assessment software that is based on the BowTie Method to assess risk. It allows users the ability to visualize complex risks in a clear way while still being detailed.Continue Reading

The BowTie Risk Assessment is a diagram method that can be used to analyse and demonstrate causal relationships in high-risk scenarios. The diagram is shaped like a Bow-Tie, creating a clear differentiation between proactive and reactive risk management.Continue Reading

Quantitative Risk Assessment (QRA) is summarised in these steps: Hazard Identification (HAZID), to determine hazard and categorisation of MAH Release Frequency Analysis, to calculate the total release frequency for all release scenarios through part counts Consequence Modelling, to model the consequences (JF, FF, PF, EX) Event Tree Analysis, to determine the potential end event likelihood...Continue Reading
