MTN TIP
Fit first, then features. Try your harness with the layers and PPE you actually wear, confirm sternal/dorsal/lateral attachment placement, and practice donning/adjustment until it’s repeatable. Pair with the right lanyard or SRL and follow the inspection schedule. Explore our Height Safety hub for compatible gear and checklists.
PRO TIPS WHEN CHOOSING A HARNESS
- Sizing & fit: Correct sizing keeps attachment points where they belong and maintains comfort over long days.
- Task profile: Rope access & rescue typically favor more gear capacity; daily fall arrest often prioritizes quick, consistent donning.
- Attachment points: Match to your system (sternal/dorsal for fall arrest; lateral for positioning).
- Inspection: Use indicators and track service life; retire any harness exposed to a significant fall.
- Accessories: Add CARITOOL holders and TOOLBAG pouches to keep hands free.

FREQUENTLY ASKED QUESTIONS
What’s the main difference between the Petzl VOLT and AVAO® FAST?
AVAO® FAST leans toward rope access/rescue with strong gear organization, while VOLT focuses on fast donning and day-to-day fall arrest/work positioning (e.g., towers, utilities).
Does either harness include a chest ascender (CROLL)?
No—chest ascenders such as TOP CROLL are optional accessories and not included by default with the VOLT or AVAO® FAST.
Which harness is better with self-retracting lifelines (SRLs)?
The VOLT’s textile dorsal attachment is well-suited to frequent SRL use and quick ground-level donning.
Are these harnesses certified for my region?
Both cover CE/EN and North American standards; AVAO® FAST also lists additional standards used in specific regions. Always verify the exact model’s datasheet for your application.
