Risk Assessment (ISO 12100)
Step 1: Identify hazards and estimate risks using a structured approach.
S - Severity
S1: Slight injury (reversible) S2: Serious injury (irreversible)
F - Frequency
F1: Rare/Short exposure F2: Frequent/Continuous
P - Avoidance
P1: Possible P2: Almost impossible
Risk Reduction Strategy
According to the Machinery Directive, priority is divided into three levels:
1. DESIGN MEASURES
Eliminate hazard at source (power reduction, geometric modification).
2. SAFEGUARDING
Use of barriers, e-stops, sensors, interlocks.
3. INFORMATION & WARNINGS
Manuals, visual/audible warnings, procedures.
Safety Functions & PL
Performance Level (PL)
Measures reliability required for a safety function. Higher risk = higher PL (PLa to PLe).
PFH Value
Probability of dangerous Failure per Hour.
Examples of Safety Functions:
• Emergency Stop • Door monitoring with interlock • Light curtains • Two-hand control
Safety System Architecture
Total Performance Level (PL) depends on combining three blocks:
INPUT
Sensors, Switches, Emergency Stop
LOGIC
Programmable Safety Controllers (Pluto), Relays
OUTPUT
Contactors, Motor Starters, Actuators
Standards & Validation
ISO 13849-1 Compliance
