DZEP_RSL_Revision_Guide

[Audio] RAIL SAFETY PRINCIPLES (HS1) DZEP / RSL Test Revision Guide Issue 2 · August 2016 · Network Rail (High Speed) Ltd. SZEP · DZEP · RSL · TS — permits, zones, protection & communications Pass mark = knowing what kills you and what saves you.

[Audio] The master mnemonic: SAVED-C Six things that will save your life — and pass your test S Zones — Safe vs Danger, distances 2.75 / 1.25 m A Access — permits, booking on, PPE, briefings V Voltage — OHLE 25 kV AC, conductor rail 750 V DC E Emergencies — ERS, switch off, rescue D Danger drills — PROD 5, safe system of work C Communication — phrases, phonetic alphabet The rest of this deck walks each letter in order..

[Audio] A · ACCESS & PERMITS The permit ladder SZEP stands alone — DZEP never does SZEP Safe Zone alone ✅ Safe Zone only, on their own DZEP Danger Zone ✅ · Safe Zone ONLY with an RSL Needs a chaperone everywhere RSL Leads groups in the Safe Zone Accompanies DZEP holders; operates ERS TS In charge in the Danger Zone Holds DZEP + RSL + TS competencies Site Warden Watches the group, warns leavers Armlet on LEFT upper arm 🧠 DZEP holder in the Safe Zone? Must be accompanied by a Rail Safety Leader..

[Audio] S · ZONES Safe Zone vs Danger Zone — “161 splits them” 161 km/h + → 2.75 m Fast trains blow harder → bigger buffer 0–160 km/h → 1.25 m Slower lines → smaller buffer Safe Zone test: Enter/leave without crossing a running line (e.g. platform) AND stand beyond the danger distance Red = Danger Zone · Green = Safe Zone 🧠 Over 161 → 2.75. Under 160 → 1.25..

[Audio] Speed exceptions (Danger Zone = 1.25 m here) 80 km/h St Pancras ↔ London Tunnel 1 (all lines) 60 km/h Stratford West ↔ Temple Mills (Link Line) 130 km/h Dagenham ↔ Ripple Lane (Chords) 100 km/h Ebbsfleet ↔ Springhead (N. Kent Conn.) 130 km/h Fawkham ↔ Southfleet (Waterloo Conn.) 130 km/h Ashford West ↔ East Jns (Chords) 100 km/h Dollands Moor (Freight Chord) 🧠 Slowest pair: 60 (Temple Mills Link) & 80 (St Pancras approach); elsewhere 100–130..

[Audio] Colour light signals (St Pancras area) Ready → set → go hierarchy 🔴 Danger — stop 🟡 Caution — ready to stop at next signal 🟡🟡 Preliminary caution — next signal may be yellow 🟢 Clear — proceed Markers: 'N' = features · 'P' = plain-line block · ID plate = your location · 100 m countdown boards · shunt = proceed on sight.

[Audio] V · VOLTAGE Electricity — “OHLE is AC-high, third rail is DC” OHLE = 25,000 V (25 kV) AC Collected by the pantograph from the contact wire Parts: contact · catenary · feeder (live 25 kV) · aerial earth · headspan Conductor rail = 750 V DC The 3 NEVERs: never STEP between it & running rail · never TOUCH anything on it · never SPLASH liquid on it Unless formally isolated + earthed by a competent person Working near OHLE: Stay below the cant line on vehicles · watch red bonds (earthing straps) · treat ALL OHLE as live until isolated AND earthed Damage to report immediately: damaged cables, oil leaks, arcing → report, keep clear, wait for a competent person 🧠 25 kV ≈ 33× the third rail — neither is survivable. Test before touch, always..

[Audio] Conductor rail — never step, touch, splash ❌ Step between conductor rail & running rail ❌ Touch anything in contact with it ❌ Direct liquid onto it ✅ Only when formally isolated & earthed 750 V DC will kill. Treat as live until proven otherwise..

[Audio] S · ZONES Phones, signage & radios ▸ Phones General (yellow) · EMERGENCY TO AFC (green) · direct to Signaller (striped) · orange arrow = nearest phone ▸ Sign types Prohibition (red) · mandatory (blue) · warning (yellow ▲) · emergency information (green) ▸ Track vocabulary CESS (by fence) · FOUR FOOT (within a track) · SIX FOOT (between tracks) · rail → fastening → sleeper → ballast 🧠 Radios DON'T work in Tunnels, Intervention shafts, Cross passages — “TIC: Technology Is Cut off.” Use tunnel phones..

[Audio] Tunnels & cross passages ▸ Never enter unless authorised + permission granted + train movements stopped ▸ London Tunnel 1 & 2 St Pancras–Stratford and Stratford–Ripple Lane; two single bores; evacuation walkway (higher/wider) + maintenance walkway ▸ Head House ALARMED — contact the EMMIS Controller before accessing; lighting by push buttons (emergency buttons only in emergency) ▸ Cross passages ≈ 660 m apart Doors open only under TS authority with trains stopped — then lock doors to the running tunnel ▸ Castell key In the Local Control Unit: removing it alarms the EMMIS Controller and the door auto-closes until the key is replaced ▸ Yellow diamonds E = emergency exit · 1/2/3 = cross passages suitable for evacuation 🧠 Door numbers: EVEN = Down (Eurotunnel) · ODD = Up (St Pancras). Number = km from St Pancras..

[Audio] Cross passage doors 1069 = kilometric point Even → Down line (Eurotunnel) Odd → Up line (St Pancras) HS1 is bi-directional — always confirm which line is live before opening doors Only a TS may authorise opening, with trains stopped. Lock the doors to the tunnel where trains are running..

[Audio] A · ACCESS Booking on/off + PPE 📋 “On then off — no loose ends” Person in charge (RSL/TS) books the group ON with the Site Access Controller before entering Books OFF when clear of the railway Booked on but not off → alarm raised — they assume something happened Alarmed buildings → contact EMMIS Controller first 🧠 RSL / lone worker also carries: PROD 5 + radio/phone + first aid kit. “Don't be the RSL without your PROD.”.

[Audio] Briefing · fitness · the train drill ▸ The briefing must cover work & location · access point/route · zone limits · safe system of work · hazards · emergency arrangements · leader-incapacitated plan ▸ Don't understand? → DO NOT access Ask the RSL/TS to explain again. Speak up — your safety depends on full understanding. ▸ Fitness & substances Report medication/conditions affecting fitness or sight — you must see clearly · never impaired · report drink/drug driving charges immediately ▸ 🚂 Train approaching — “Safe · Down · Face” 1) Safe Zone (min 2 m from rail) · 2) put down what you carry — secure it · 3) stand still and FACE the train until it passes ❌ Never ride steps, never board or alight a moving vehicle..

[Audio] Danger to trains & security 🚨 Report immediately: On the train: open door · insecure load · flat wheel · hot axle · headlight out · tail lights missing · repeated long horn · person outside · ice thrown up On the line: track fault · FIRE · obstruction · large animal Person in charge reports AND acts (e.g. stop trains) 🔒 Suspicious item — 3 Ds: Don't touch · don't use mobile/radio near it · DO clear everyone Trespasser → person in charge → Ashford Control Centre immediately If safe: approach calmly · ask to leave · escort off · warn · report to manager Walk only approved walking routes and access points.

[Audio] E · EMERGENCIES Emergency protection — the ERS Who: the RSL (Safe Zone) Tells the Signaller + operates the ERS Key: Berne key Kept by the person in charge Signs: red/black triangles Arrow shows direction to the nearest ERS; the board diagram shows the area protected ERS are found near most block section markers and colour light signals.

[Audio] Switch off & rescue — “don't touch, do insulate” ▸ Emergency switch off Person in charge requests it for: damaged OHLE · contact with OHLE · fire · smoke · arcing · fallen cables ▸ Switch-off ≠ safe to touch Only a formal isolation with earthing makes it safe. Keep the Signaller informed until relieved; confirm everyone clear before power is restored ▸ OHLE casualty Don't touch the person or anything on the wire → request switch off → beware step potential ▸ Conductor rail casualty Never touch directly (750 V) → break contact with something dry & non-conductive — cover your hands 🧠 Golden rule: never assume isolation — always test before touch..

[Audio] D · DANGER DRILLS Personal protection — PROD 5 For quick, unplanned work — the RSL applies it with an ERS The 3 options 1 — stop Track A only · 2 — stop A + speed restriction on B · 3 — stop A and B “1 stops one · 2 slows the other · 3 stops everything” The 7 steps — say it as a rhythm: CHECK (in Safe Zone) · CALL (Signaller) · PROTECT (ERS, Berne key) · CONFIRM (protection in place) · WORK (stay alert) · RESET (ERS to normal) · RELEASE (confirm removal) CHECK-CALL-PROTECT-CONFIRM-WORK-RESET-RELEASE.

[Audio] Safe system of work RSL runs the Safe Zone · TS runs the Danger Zone ▸ Safe Zone work Prevent drift into the Danger Zone with an approved safety fence OR warning boards + track protection on the adjacent line ▸ Danger Zone work — EZP Engineering Zone Protection closes the section and sets signals to Danger · limits marked by ID plates in the 4-foot on the sleeper (e.g. “4 EZP TU16”) · TS arranges local protection: stop boards + worksite marker boards ▸ Worksite the safe work area (green) sits inside the Protected Area (red) ▸ Site Warden constant watch · warns leavers until acknowledged · escalate if ignored · persistent offenders → stop the work · armlet LEFT upper arm 🧠 Golden rule: never enter the Danger Zone unless trains are stopped/protected..

[Audio] Worksite options A–G — a ladder of protection A cess/six-foot, trains on adjacent line B 4-foot/six-foot with safety fence C minor work, trains under caution — documented authorisation D one line under EZP, other running E Danger Zone work, fence between lines F ALL lines blocked (EZP) G overlapping zones — special authorisation Double-line tunnel (North Downs): Option A or B from walkways 🧠 F = Full closure · G = Got to ask specially..

[Audio] C · COMMS Communication — most incidents start here Protocols apply ALWAYS, not just in emergencies ▸ Lead responsibility The person in charge owns the message — confirm it was received AND understood ▸ Who to call AFC Signaller / Ashford Control Centre for anything affecting train safety · 🚫 DO NOT CALL 999 · book on/off with the Site Access Controller ▸ Rules Structure your message · plan it (no “um/er”) · repeat back safety-critical messages · standard phrases + phonetic alphabet 📟 Emergency call — E-I-D-D-A: Emergency first (“This is an emergency call”) · Identify (“Is this the AFC Signaller?”) · Describe yourself (name, role, KP) · Describe what/where · Action needed. Prompt sheet is in your PROD 5 pack — always carry it. 🧠 “Over = waiting · Out = done.” · Negative = no · Correction = fixing my last words · Disregard = ignore my last message..

[Audio] The phonetic alphabet Use it for block markers, signals and locations A alpha B bravo C charlie D delta E echo F foxtrot G golf H hotel I india J juliet K kilo L lima M mike N november O oscar P papa Q quebec R romeo S sierra T tango U uniform V victor W whisky X x-ray Y yankee Z zulu 🧠 Drill yourself: say AF706CA aloud with the alphabet before the test..

[Audio] Golden rules & quick-fire facts Read this slide three times before the test ⚡ QUICK-FIRE 2.75 m / 1.25 m · 25 kV AC / 750 V DC DZEP needs an RSL even in the Safe Zone Even = Down · Odd = Up · 660 m apart Berne key · book on AND off · AFC not 999 PROD 5 = 7 steps · armlet LEFT arm Radios dead in tunnels/shafts/cross passages Red/Yellow/Double-yellow/Green Face the train · 2 m clear · Safe-Down-Face “This is an emergency call” comes FIRST ALWAYS ✅ Plans & permits before work · fit-for-purpose kit · harness at height · test before earthing · speed limits & seat belts · comms protocols NEVER ❌ No job without training/competence · never impaired · never assume isolation (test before touch) · never phone while driving · never enter an exclusion zone unless directed · never enter the Danger Zone unprotected.
