Safety Risk Assessments & Hazard Analysis
(ISO 12100, ISO 13849, IEC 62061)
Every safety-critical automation project begins with a structured risk assessment. This systematic process identifies hazards, evaluates severity and likelihood, and assigns the required safety performance level (PLr) or safety integrity level (SIL).
Thank you for reading this post, don't forget to subscribe!At SIS Automations, we perform comprehensive hazard analyses aligned with global standards to ensure your automation system is both safe and compliant.
Why a Risk Assessment Is Essential
Automation introduces unique and sometimes hidden risks:
High-speed or high-force machinery
Unexpected motion from PLC logic or robotics
Human interaction during setup, cleaning, and maintenance
Stored pneumatic or hydraulic pressure
Thermal, electrical, and process-related hazards
A proper assessment ensures safety is engineered into the system from the very beginning — not added afterward.
Industry Standards We Follow
Our assessments adhere to leading global safety standards, including:
ISO 12100 for hazard identification and risk reduction
ISO 13849 for defining and validating PLr
IEC 62061 for SIL determination and functional safety lifecycle
These standards create a framework that defines how risks should be evaluated and mitigated through engineering controls.
Key Steps in Our Risk Assessment Process
SIS Automations performs structured, traceable assessments that include:
Hazard Identification – Mechanical, electrical, motion, energy, and human-factor hazards
Risk Estimation – Evaluating severity, exposure, and possibility of avoidance
Risk Reduction Strategies – Safeguarding, interlocks, safety PLC logic, devices, and redesign
PLr/SIL Assignment – Determining required safety levels
Architecture Selection – Choosing the correct control structure (Category 1–4, SIL 1–3)
Verification & Validation – Ensuring all mitigations work as intended
Documentation – Comprehensive reporting for compliance and audits
Deliverables You Receive
We provide a detailed, audit-ready package that includes:
Hazard identification tables
Risk matrices
Determined PLr/SIL requirements
Recommended safety devices and architecture
Validation results and approvals

Commissioning
Pitfall: Lack of detailed planning, inadequate documentation, or incomplete specifications can lead to misunderstandings, errors in design, and misaligned expectations Consequences: This can result in system malfunctions, inefficient operation, or even complete system failure. It may also lead to costly delays and the need for rework. Prevention: Ensure thorough planning, clear documentation, and communication among all stakeholders. Use checklists and detailed commissioning plans.
Why Choose Us
benefit 1. Custom-Engineered for Your Process — Not Cookie-Cutter Code
We don’t reuse generic PLC templates. Every control logic we design is engineered around your unique process, equipment, and safety standards — ensuring smoother startup, higher efficiency, and easier future expansion.
benefit 2. Fast Commissioning with Zero-Downtime Philosophy
Our structured programming, simulation testing, and on-site validation minimize commissioning delays. Clients experience faster go-live and less downtime, saving both production time and maintenance costs.
benefit 3. Future-Proof, Scalable Architecture
We build modular, well-documented code that supports upgrades, expansions, and integration with Industry 4.0 platforms. That means your automation investment keeps delivering value for years to come — no full reprogramming required.
benefit 4. Engineer-to-Engineer Collaboration
You work directly with experienced controls engineers — not sales reps. We speak your language, understand your process challenges, and design reliable automation systems that meet your goals from the first day of production.
