Permit to Work (PTW) — Digital Safety Authorization Platform
A configurable, enterprise-grade Permit to Work system that digitizes, controls and
standardizes work authorization across high-risk industrial environments — enforcing safety
through dynamic checklists, mandatory digital signatures, and complete audit traceability.
Context
The challenge and our response
Problem
- Paper-Based PermitsManual permits prone to errors, delays, missing approvals and unsafe work execution.
- No Real-Time ControlSupervisors lacked visibility into active, expired, suspended or overlapping permits.
- Weak Audit ReadinessDuring audits or incidents, reconstructing who approved what — and when — was difficult.
- Inconsistent Safety ChecksChecklists varied by person or site, leading to non-standard safety enforcement.
- Delayed ApprovalsManual coordination caused permit bottlenecks and unsafe workarounds on the ground.
- No Digital TraceabilityLack of digital signatures, images and timestamps weakened accountability.

Solution
- Dynamic Checklist GenerationAutomatically generates safety checklists based on work type, risk category, equipment and location.
- Mandatory Digital SignaturesEnforced at every stage — creation, approval, work start, suspension, extension and closure.
- Visual Evidence & AnnotationUpload and annotate images to highlight hazards, restricted zones and safety instructions.
- Permit Types CoveredHot work, electrical, confined space, work at height and cold work — each with enforced precautions.
- BPMN Workflow EngineCamunda-based engine for multi-level and parallel approvals driven by permit type, risk level and hierarchy.
- Tamper-Proof RecordsDigital signature pad across full lifecycle; structured, read-only records for audits.

Platform Modules
Core modules — from configuration to compliance
A
Permit Configuration & Types
Define multiple permit types with custom rules, risk categories, safety parameters, validity, extensions and revalidation.
B
Dynamic Checklist & Risk Assessment
Context-aware checklist generation, risk assessment embedded in permit flow, mandatory confirmations before approvals.
C
Workflow & Approval Engine
Camunda BPMN workflow engine; multi-level and parallel approvals driven by permit type, risk level and hierarchy.
D
Notifications & Escalations
Email alerts for approvals, pending actions and expiry warnings; time-based escalation logic.
E
Digital Evidence & Signatures
Image uploads with annotations; digital signature pad across full lifecycle; tamper-proof authorization records.
F
Archival, Retention & Compliance
Configurable archival by status and age; read-only access for audits; automated purging aligned with regulatory policy.
Permit Types
Comprehensive coverage across high-risk work
Hot Work
Controls welding, cutting, grinding and fire-risk activities with enforced precautions
Electrical Work
Ensures isolation, verification and authorization for electrical maintenance
Confined Space
Mandates atmospheric checks, rescue plans and controlled entry
Work at Height
Validates PPE, anchorage points and fall-protection measures
Cold Work
For non-spark, low-risk maintenance activities
Custom Types
Configurable to add site- or industry-specific permit variations
Business Impact
Outcome for safety & compliance
01Enhanced safety and regulatory compliance across shifts, sites and contractors.
02Reduced operational risk through standardized, enforced safety checks.
03End-to-end traceability for audits and incident investigations.
04Scalable across sites, languages and regulatory regimes.
