risk assessment process step 1 ID hazard

Find potential harm sources with methods like HAZOP: review deviations-high flow in pipe line or bow tie analysis- maps threats (corrosion) to consequence (tank rupture)

step 2 who might be harmed

define affected groups: Workers: toxic exposure during maintenance. Public: Gas cloud dispersion near site.

step 3 evaluate risk and implement control

use tools like matrix risk: likely hood over risk. or LOPA quantifies safeguards(relief valve < risk x10) hierarchy of hazard controls.

Step 4 Record significant findings.

document risk and control Risk register: track high risk items(HF release controlled by scrubber) safety reports- legal requirement for hazard site.

Step 5 Review and Update

update assessments after- incidents (gaps in corrosion monitoring) Regulatory changes: revised OSHA PSM amendments.

applying risk management tool 1 concept phase

A structured team exercise to spot potential hazards early. brainstorm risks- toxic release during chem transport.

what is a what it scenario?

challenges assumptions by asking what if? Tests design safety- what if emergency shut down fails? Output- guidelines COMAH safety reports

2 design phase HAZOPS

systematically examines process deviation. Purpose- finds unsafe scrnarios. UK practice independent facilitators lead studies (HSG 48)

visualise risks, controls and consequences maps threats- corrosion to safeguards- inspections. required for uk offshore safety cases (OSDR 2015)

what is ETA Event Tree Analysis

predicts incident escalation paths. quantifies outcomes- chance of ignition after gas leak. proves ALARP compliance for HSE

FMEA - failure modes and effects analysis

identifies equipment failure impacts Rates failures - pump seal leak > fire UK example- used ammonia terminal valves (PSSR)
