Functional safety consulting and staffing
Functional safety support for teams building regulated systems.
Critical Systems Analysis helps robotics, automotive, machinery, rail, medical software, autonomy, and process-industry teams plan the right safety work, produce usable evidence, and hire functional safety talent.
Assessment and certification supportSafety case and lifecycle evidenceContract and direct-hire staffing
Deep expertise. Broad coverage.
From robot cells to rail signalling, CSA works across the systems where a failure has real consequences.
Services
See all servicesSafety consulting with staffing built in.
Each service ends in a practical outcome: a decision, a document, a review package, trained people, or the right specialist on the team.
Functional safety assessment
Find the gaps that block a credible safety claim.
Certification support
Get the evidence package and assessor coordination under control.
Safety case
Turn lifecycle evidence into a clear argument for release.
Training
Give teams the standards language and decisions they need.
Staffing
Add functional safety engineers, assessors, and managers when timing matters.

Standards
The standards CSA supports.
Standards define the lifecycle and evidence expected for the product. Tooltips explain terms like , , PL, and safety case without sending readers away from the page.
ISO 13849
ISO 13849 covers safety-related parts of machinery control systems using Performance Levels. CSA applies it to safety functions, architecture categories, diagnostic coverage, validation plans, and machine-control evidence.
Learn more →IEC 62061
applies principles to machinery safety-related control systems. It is useful when teams need SIL-based machinery evidence for electrical controls, subsystems, and verification.
Learn more →ISO 21448/SOTIF
addresses hazards caused by functional insufficiencies and foreseeable misuse, even when no component has failed. CSA uses it for scenario analysis, perception limits, validation strategy, and autonomy safety arguments.
Learn more →IEC 62304
IEC 62304 defines the software lifecycle expected for medical device software and software embedded in medical devices. CSA treats it as a safety-critical software route when product teams need requirements, risk controls, verification evidence, and release discipline that can survive regulatory review.
Learn more →EN 50128/50126/50129
The EN 5012x rail standards cover , railway software, and signaling safety cases. CSA uses the set to connect hazard logs, allocation, software lifecycle evidence, and safety case structure for rail programs.
Learn more →ISO 10218
ISO 10218 defines safety requirements for industrial robots and robot systems. CSA uses it for robot-cell hazards, integration duties, safeguarding, validation evidence, and links to machinery-control standards.
Learn more →ISO 3691-4
covers driverless industrial trucks and automated guided vehicles. CSA uses it for navigation hazards, protective fields, operating zones, commissioning, and evidence for warehouse automation.
Learn more →ANSI/UL 4600
ANSI/UL 4600 is a safety case standard for autonomous products that operate without human supervision. CSA uses it to organize claims, arguments, evidence, assumptions, and operational design constraints.
Learn more →IEC 61511
applies functional safety to process-industry safety instrumented systems. CSA uses it for SIF definition, verification, proof-test planning, lifecycle records, and audit-ready SIS evidence.
Learn more →ISO 26262
is the functional safety standard for road vehicle electrical and electronic systems. CSA uses it to structure , decomposition, safety requirements, verification, and release evidence for automotive and autonomy teams.

Start with the business question: ship a product, pass an assessment, train a team, or fill a role.
1ScopeWe map the product, hazards, standards, target markets, and staffing gaps before writing a plan.2BuildCSA engineers and matched specialists create the analyses, requirements, tests, training, and safety case evidence.3SupportWe prepare assessment reviews, certification conversations, hiring loops, and change-control routines.
Staffing
Find functional safety talentBring functional safety talent into the work.
CSA supports direct hire, contract, contract-to-hire, embedded teams, fractional leadership, and project-based delivery.
Hire talent
Describe the standards, lifecycle phase, role, and timing. CSA matches from staff, partners, and the FSTalent network.
