Pneumatic Tool Safety

Overview

Pneumatic Tool Safety should be managed through a planned system of work: identify the task-specific hazards, eliminate exposure where practical, use engineered or collective controls before relying on PPE, verify critical safeguards before starting, and stop the task when controls are missing or conditions change. This guide applies those principles specifically to safe hoses, couplings, pressure control and operation of pneumatic tools.

Main Hazards

• • Hose whip or coupling separation
• • High-velocity particles, noise and unintended tool activation
• • Unexpected energization or start-up
• • Electric shock, arc or stored-energy release
• • Contact with moving or unguarded machine parts

Essential Controls

1. 1Inspect hoses, couplings and retaining devices before pressurizing.
2. 2Depressurize before disconnection, adjustment or maintenance.
3. 3Identify every hazardous energy source before intervention.
4. 4Isolate, lock, release stored energy and verify a safe state before work.
5. 5Keep guards and protective devices in place unless an approved safe isolation requires removal.
6. 6Use competent persons and equipment suitable for the electrical or mechanical duty.
