Petzl Exo Tactical vs Grillon Hook: Choosing the Right PPE for Your Work-at-Height Scenario

There is no universal answer. There's only your situation.

I coordinate expedited PPE orders for rescue teams, industrial crews, and public safety agencies. In my six years and roughly 200 rush orders, the biggest mistake I see isn't cheap gear. It's assuming one good product fits every job. That's why I split equipment decisions into scenarios. If you're trying to decide between a Petzl Exo Tactical and a Petzl Grillon Hook Adjustable Positioning Lanyard, the first question is: what exactly are you doing at height?

Here's the quick version:

• Need to adjust your position while attached to a beam, column, or structure? Look at Petzl Grillon Hook Adjustable Positioning Lanyard.
• Need a compact tactical system that works with body armor and lets you move around a structure? That's Petzl Exo Tactical territory.
• Need fast, practical ground-level PPE for staging, food-contact areas, or moving between sites? That's where slip-on boots, a class 2 hard hat, and food-grade nitrile gloves come in.

No judgment here. A specialized harness is overkill for a packaging room, but a pair of slip-on boots is dangerous on a ladder. Let's go through each scenario.

Scenario 1: You need to position yourself on a structure

If you're on a concrete column, rebar, or steel beam and need your hands free, a positioning lanyard is the tool. The Petzl Grillon Hook Adjustable Positioning Lanyard is designed for exactly that. You can adjust the length without unhooking, which is huge when you're balancing on a narrow surface.

But here's the distinction that matters: it's a positioning lanyard, not a fall-arrest lanyard. It keeps you from moving too far from your anchor, but it doesn't absorb the energy of a serious fall. For fall arrest, you still need a full-body harness and an energy-absorbing lanyard or self-retracting lifeline. Weirdly, I've had more than one job try to use a positioning lanyard as the only tie-off. That is exactly how the 'simple rule' advice falls apart.

What most people don't realize is that 'positioning' has a legal meaning. ANSI/ASSP Z359.3 puts positioning systems in their own category, and OSHA's positioning-device rule at 1926.502 uses a 2-foot free-fall limit. That should tell you how carefully these tools are treated. A positioning lanyard can be part of a fall protection plan, but it's not the fall protection by itself.

If you're choosing between the Petzl Exo Tactical and the Petzl Grillon Hook, you're not choosing 'better' vs 'worse.' You're choosing a system for a specific movement pattern.

One more thing: because the Grillon is adjustable, the crew needs to test that adjustment before going up. I had a job where a hook couldn't close around an oversized steel channel. The lanyard was fine; the anchor interface was wrong. That's the kind of mismatch that doesn't show up on a spec sheet.

In March 2024, a rescue coordinator needed 10 Grillon lanyards for a confined-space training the next morning. Normal delivery was five days. We paid a $190 expedite fee and drove two hours to meet a courier. The cost stung, but it beat the alternative: canceling a state-certified practical scenario. My point is not that the Grillon is perfect for everyone. It's that for this kind of positioning work, it solved a problem that a generic lanyard can't.

Scenario 2: You need tactical mobility at height

For police tactical units, military operators, or anyone wearing a ballistic vest, a standard climbing harness can be frustrating to put on. The Petzl Exo Tactical is a work-positioning system built around that reality. It keeps the operator connected while moving around a structure, and it doesn't add a bulky seat harness to the whole setup.

Important boundary: the Exo Tactical is not a substitute for a full fall-arrest harness if the task can produce a fall with high force. It's a positioning and restraint system. Think of it as one layer in a bigger system. If you need fall protection as well, your plan must include an energy-absorbing component. A vendor who tells you 'this one product does everything' is not respecting your safety. That's the kind of overpromising I walk away from.

When you spec an Exo Tactical, also check that the attachment connectors are rated for your load path. Tactical gear gets used around corners and edges, and edge conditions can reduce the rating of a rope or lanyard. If there is any chance of contact with abrasive concrete or metal, protect the edge or adjust the rigging.

It took me years to appreciate that. I used to ask 'which harness is the best?' The smarter question is 'which part of this system is missing?' If you're doing tactical work, you might need the Exo Tactical for mobility and a separate fall-arrest lanyard for the edges.

Scenario 3: Ground support and fast-moving roles

Now the other end of the spectrum. I take a lot of calls from supervisors who need basic gear fast. Two of the most common questions are 'can I use nitrile gloves for food?' and 'is a class 2 hard hat enough?'

Let's handle the gloves first. Yes, there are food-safe nitrile gloves. But not every nitrile glove is food-grade. Check the box for a food-contact statement, usually referencing FDA 21 CFR 177.2600. And just because you used a pair of heavy nitrile gloves for a chemical spill doesn't mean those same gloves are okay for sandwich prep. The label only counts before the glove is contaminated. (We learned this after a warehouse crew used the same box for cleaning solution and a staff lunch service. Ugh.)

One more note on the glove question: if the glove is food-grade and you're only handling food, that's fine. If you're also using it for tasks with oils, chemicals, or rescue gear, it stops being food-safe the moment it touches something else. I keep two colors in the kit: blue for food, black for work. That simple color rule has saved more than one lunch.

For head protection, if people search 'class 2 hard hat', they often don't know which standard they're asking about. In ANSI/ISEA Z89.1, hard hats are sorted by Type (I or II) and Class (C, G, or E). Type II covers side impact. Class E protects against high-voltage contact up to 20,000 volts. Class G covers lower voltage (2,200 volts). So if you need lateral protection and electrical protection, look for a helmet that says Type II, Class E on the label. The words 'class 2' alone don't tell you enough. OSHA 1910.135 requires head protection where falling objects or bump hazards exist, and the label is how you verify it.

And yes, slip-on work boots have a place. They're great for staging areas, equipment rooms, and food-safety environments where you're going from point A to point B fast. But if you're climbing ladders, walking on a roof, or doing rope access, slip-on boots are not my first choice. They can come off in awkward situations, and they usually lack the heel and ankle support you need on uneven surfaces. Keep them in the truck for support staff, not for the climbers.

How to tell which scenario you're in

Use three questions:

1. Will I be attached to a structure while my hands are working? If yes, start with a positioning lanyard like the Grillon Hook.
2. Am I wearing a tactical platform and need to stay low-profile? Then look at the Exo Tactical assembly and plan a separate fall-arrest layer.
3. Am I mostly on the ground, or in food and chemical environments? Then focus on food-grade nitrile gloves, a class 2 hard hat that actually meets the right Type and Class label, and slip-on boots if speed matters more than ankle support.

If you're still unsure, the tie breaker is the fall distance. For any task where a fall could generate force, positioning gear is not the final answer. You need a certified fall-arrest system, and you need a competent person to review the system before you use it. That's not a marketing dodge. It's a boundary. A specialist who tells you what they don't cover is more trustworthy than one who claims to cover everything.

Honestly, a rushed decision made under pressure is how I get called at 10pm. If your procurement process has no buffer, build one. Add a pre-approved product list for each scenario so someone can order the Petzl Grillon Hook or the Petzl Exo Tactical without gambling on a generic alternative.
