🚨 PERMIT TO WORK (PTW) – THE SAFETY GATEKEEPER FOR HIGH-RISK WORK
A Permit to Work is not simply a form or signature. It is a formal work-control and authorization system designed to ensure that hazardous or non-routine work is properly planned, risks are assessed, precautions are established, and the people involved understand the job conditions before work starts. ✅
🔹 WHY IS PTW IMPORTANT?
A properly implemented PTW system helps to:
✅ Identify hazards before work begins
✅ Assess risks and establish effective controls
✅ Define the exact scope, location and duration of work
✅ Confirm required isolations and LOTO
✅ Ensure workers are trained and authorized
✅ Coordinate simultaneous operations (SIMOPS)
✅ Establish emergency and rescue arrangements
✅ Improve communication between operations, maintenance, contractors and HSE
✅ Prevent unauthorized or uncontrolled work
✅ Ensure proper suspension, handover and close-out of the job
👷 KEY PTW ROLES
🔵 Permit Issuer / Authorizing Person
• Reviews the work scope
• Verifies hazards and risk controls
• Confirms required isolations
• Checks site conditions
• Ensures precautions are implemented
• Authorizes and signs the permit
• Communicates permit conditions
🟠 Permit Receiver / Performing Authority
• Understands the scope and permit conditions
• Conducts/participates in toolbox talk
• Ensures workers understand the hazards and controls
• Follows all specified precautions
• Stops work when conditions become unsafe or change
• Reports deviations and incidents immediately
• Ensures the permit is properly returned/closed
🔄 BASIC PTW LIFECYCLE
1️⃣ Work Request – Clearly define what work is required.
2️⃣ Risk Assessment – Identify hazards and determine controls.
3️⃣ Isolation & Preparation – Apply required LOTO, depressurization, draining, gas testing, barricading, etc., as applicable.
4️⃣ Permit Issue – Verify controls and authorize the work.
5️⃣ Toolbox Talk – Brief everyone on hazards, controls and emergency arrangements.
6️⃣ Work Execution & Monitoring – Perform work within permit conditions.
7️⃣ Suspension/Extension – Reassess and reauthorize when required.
8️⃣ Close-Out – Confirm work completion, restore systems safely and close the permit according to site procedure.
🔥 EXAMPLES OF WORK THAT MAY REQUIRE PTW
• Hot Work – welding, cutting, grinding
• Confined Space Entry
• Electrical work and isolation/LOTO
• Line breaking / opening process equipment
• Excavation where covered by site PTW requirements
• Lifting operations where controlled through the site's PTW system
• Work on hazardous process equipment
• Other high-risk or non-routine activities as defined by the site procedure
⚠️ IMPORTANT: PTW requirements depend on the applicable OSHA standard, industry, site procedure and type of work. PTW should not be treated as a substitute for risk assessment, isolation, engineering controls or competent supervision.
🛑 STOP WORK IF:
❌ Job conditions change
❌ Gas-test results become unsafe
❌ Required isolation is not verified
❌ Required PPE/control measures are missing
❌ Weather or site conditions create additional risk
❌ The actual work no longer matches the permit scope
📋 BEFORE STARTING THE JOB – ASK:
☑️ Is the scope clearly defined?
☑️ Have all hazards been identified?
☑️ Are controls actually in place?
☑️ Are required isolations verified?
☑️ Is gas testing required?
☑️ Are workers competent and authorized?
☑️ Has the toolbox talk been completed?
☑️ Are emergency arrangements available?
☑️ Are SIMOPS identified and controlled?
☑️ Is the permit valid for the current conditions?
⚠️ GOLDEN RULE
NO VALID PERMIT + NO REQUIRED CONTROLS = NO WORK.

📌 Safety Reminder:
A permit does not make the job safe. The effective implementation and verification of the controls make the job safer.
