Safety Instrumented Systems and SIL to IEC 61511 course coverFree
FreeSafetyAdvanced

Safety Instrumented Systems and SIL to IEC 61511

The protection layer that acts once control has already failed: why the SIS is kept apart from the BPCS, safety instrumented functions written with a trip point and a safe state, LOPA and the SIL target, PFDavg arithmetic, sensors, logic solvers and shutdown valves, de-energise against energise to trip, bypass and MOS discipline, 1oo2 and 2oo3 voting, common cause failure, the safety requirements specification, application programs, validation, proof testing and repair deferral.

  • Say in one paragraph why a safety instrumented system is kept independent of the basic process control system
  • Write a safety instrumented function with a trip point, a safe state and a response time a designer can build from
  • Follow a LOPA to a SIL target and check it with a PFDavg calculation and a proof test interval

HSE Safety Officer Foundations: Risk, PTW and ISO 45001 course coverFree
FreeSafetyBeginner

HSE Safety Officer Foundations: Risk, PTW and ISO 45001

The daily work of a site safety officer, built on the ISO 45001 management system: hazard identification and risk matrices, the hierarchy of controls, JSAs, permits to work and isolation, work at height, confined spaces, lifting, fire and emergencies, health hazards, incident investigation, safety KPIs, and leadership and reporting.

  • Explain why accidents happen with the Swiss cheese and domino models, and what a safety officer does each day
  • Map ISO 45001 clauses 4 to 10 onto Plan-Do-Check-Act and run worker consultation
  • Identify hazards and score risk on a written 5 x 5 matrix, then choose controls in hierarchy order

Machine Safety: ISO 12100, ISO 13849 and SISTEMA course coverFree
FreeSafetyIntermediate

Machine Safety: ISO 12100, ISO 13849 and SISTEMA

Do the whole machine safety job, not one vendor's part of it: an ISO 12100 risk assessment, guards and interlocks, light curtains with a checked safety distance, the required performance level, a category 3 or 4 design, MTTFd, DCavg and CCF, PL verification in the free SISTEMA tool, validation to ISO 13849-2, IEC 62061 compared, and the technical file the EU Machinery Regulation 2023/1230 expects from 20 January 2027.

  • Carry out an ISO 12100 risk assessment task by task and apply the three-step method in order
  • Choose fixed guards, interlocks and guard locking, and the ISO 14119 device type and coding level
  • Calculate light-curtain safety distances with the ISO 13855 method from measured stopping times

HAZOP and Process Safety Management course coverFree
FreeSafetyIntermediate

HAZOP and Process Safety Management

Process safety for oil, gas, chemical and refinery engineers: why major accidents happen, the OSHA PSM elements, CCPS risk based process safety and COMAH, process hazards, HAZID and what-if, reading P&IDs into nodes, HAZOP guidewords and deviations, causes, consequences and safeguards, risk matrices and ALARP, running and recording a HAZOP, LOPA as the bridge to SIL, bow-tie analysis, management of change, PSSR, mechanical integrity, CSB case studies and API RP 754 indicators, ending with a full HAZOP of a separator node.

  • Explain how process safety differs from personal safety, using BP Texas City and other major accidents
  • Map a site's documents to the 14 OSHA PSM elements and the CCPS risk based process safety pillars
  • Judge fire, explosion, toxic and runaway hazards from safety data sheets and Le Chatelier's rule

What this leads to

Internship

PLC Programming

Free internship: 4 weeks, a free certificate and nothing to buy. The Engineer-verified internship adds an engineer's review and the graded certificate.

See the internship

Lab

Roles

PLC and automation

Roles that ask for this skill, 524 open in this country now. Free to see and to apply. We are not a recruitment agency.

Practise what you learn in the free 3D lab

Technical work is judged on what you can do: wiring, commissioning, finding a fault. Doing a task yourself teaches more than watching it a second time, and a lab lets you try it safely before you meet real equipment. It does not replace working on real hardware.

Questions

Is this a certification?
It is a foundation for TÜV-style certification, not a replacement for it.
Is functional safety different from safety PLC programming?
Programming an F-CPU or GuardLogix is one part; the courses also cover the standards (ISO 13849, IEC 62061) and the risk assessment that decides what the program must do.
