Robust PTW design for hot work, confined space, and high-risk tasks
Permit-to-Work (PTW) systems govern high-risk tasks — hot work, confined space, work at height, electrical, breaking containment. We design or upgrade PTW programmes covering procedure, IT system, training, and audit per Energy Institute and HSE guidance.
A practical, phased delivery approach — from gap assessment through operational embedding — built around your regulatory context.
Define PTW scope covering hazardous activities — hot work (HSG 250 / NFPA 51B), confined space (OSHA 1910.146 / EN 547), working at height (HSE WAH Reg / EN 363), lockout/tagout (OSHA 1910.147), electrical (NFPA 70E).
Design PTW procedure with hierarchy — Operator Permit (low-risk), Engineer Permit (moderate), Hot Work Permit (high), Confined Space Entry Permit (very high); design forms per ISO 45001 / OSHA / HSE INDG 98.
Specify pre-work checks per permit type — JSA / TRA / Last Minute Risk Assessment, gas testing (LEL / O₂ / H₂S / CO), isolation / lockout / tagout verification, fire watch deployment, rescue plan; align with task hazard analysis.
Specify authorisation hierarchy — Permit Holder (worker), Permit Issuer (qualified supervisor), Performing Authority (qualified engineer), Area Authority (operations supervisor); specify competency per role with periodic certification.
Design SIMOPS management for parallel permits in same area — clash detection, MOC trigger, deconfliction meeting; align with offshore SIMOPS guidance per OGUK / IADC / IMCA.
Design PTW audit programme — daily field audit by operations supervisor, weekly permit-quality audit, monthly programme review; align with corporate HSE governance and learn-from-incident process.
