Is the ABUS 74/40 10-Pack Keyed Different the right lockout/tagout padlock for equipping an electrical maintenance crew under OSHA 1910.147?

Short answer: Yes — if you need to issue personal locks to a full crew working around electrical energy, the ABUS 74/40 is a strong fit: ten lockout padlocks keyed different so every worker controls a unique key, in a non-conductive thermoplastic body suited to electrical isolation. Buy it when dielectric properties and per-worker keying both matter; if you instead need one key to cover several isolation points for a single technician, look at a keyed-alike option in our lockout/tagout range. Unsure which keying applies, start with how to choose a lockout padlock.

ABUS 74/40 Lockout Tagout Padlocks, 10-Pack Keyed Different Review (2026)

In a lockout/tagout program, the padlock is the device that physically holds an energy-isolating point — a breaker, disconnect, or valve — in the safe position so equipment cannot be re-energized while a worker is exposed. The ABUS 74/40 fills the "personal lock" role: each of the ten locks in this pack is keyed different, so one worker holds the only key to their own lock, which is the foundation of the one-worker-one-lock-one-key rule at the heart of OSHA 29 CFR 1910.147. What sets this unit apart from aluminum and steel siblings in our lockout padlock lineup is the non-conductive thermoplastic body — a property electrical crews specifically look for when isolating energized circuits. Pair these locks with hasps for group work and tags for worker identification, and they slot directly into a compliant lockout/tagout workflow. For the procedural side, see how to perform LOTO.

Editorial verdict — 4.6/5
At a 10-pack price point, the ABUS 74/40 delivers ABUS build quality plus a genuinely useful non-conductive body and per-worker keyed-different keying — a cost-effective way to equip a crew without compromising on the electrical-LOTO requirement that drives most padlock selection.VIEW ON WC SAFETY →CHECK PRICE ON AMAZON →

What the ABUS 74/40 (10-Pack KD) does well

Non-conductive body for electrical isolation

The thermoplastic body is the standout feature: electrical crews isolating live circuits favor a non-conductive lock to reduce conductivity risk at the panel. That makes the 74/40 a more deliberate electrical-LOTO pick than the metal-bodied options in our lockout padlock range. Read more in lockout vs tagout.

Keyed-different = true personal control

Every lock in the pack carries its own unique key, so no other lock in the set opens it. That is exactly the configuration 1910.147 expects when each authorized employee must retain sole control of their own key. It contrasts with keyed-alike sets like the ABUS 2ALHB/40-75.

Crew-scale economy in one order

Ten locks in a single pack let a safety manager equip a whole maintenance crew at once instead of buying singles — the same issuance logic behind the TRADESAFE TSKAU10YL yellow set. It keeps your lockout/tagout standardization consistent across the team.

ABUS build consistency

ABUS is a long-established padlock maker, and the matched 10-pack arrives with uniform fit and finish — useful when you want every worker's lock to look and operate identically on a hasp. Standardization is itself a 1910.147 durability-and-identifiability expectation.

Lightweight daily carry

The thermoplastic body keeps each lock light on a tool belt, which matters when an electrician carries several across a shift. For a heavier-duty metal alternative, compare the American Lock A1107R.

Where the ABUS 74/40 (10-Pack KD) falls short

Keyed-different isn't universal

If a single technician needs one key to open several locks across multiple isolation points, keyed-different is the wrong tool — that is a keyed-alike job, like the ABUS 2ALHB/40-75. See how to choose a lockout padlock before deciding.

Standard shackle reach

The 74/40 carries a standard shackle, which is fine for typical hasps but won't span deep or stacked hasps the way a long-shackle lock does. For those, a long-shackle option from the lockout padlock range is the better fit.

No published dielectric rating

The listing describes the body as non-conductive thermoplastic but does not publish a tested dielectric voltage rating. Treat it as a material property supporting 1910.333 work practices, not a certified electrical rating — verify against your own program requirements.

Key-control overhead

Ten unique keys means more duplicate-key and master-key control to manage than a single-key keyed-alike set. Build that into your lockout station and key-control procedure from the start.

When to step up from the ABUS 74/40 (10-Pack KD)

If your crew works heavily around energized electrical equipment, the 74/40's non-conductive body is itself the step up over metal-bodied 10-packs like the TRADESAFE red set. Where you need a single key to control several isolation points for one authorized worker, step sideways to a keyed-alike lock such as the ABUS 2ALHB/40-75 long-shackle. And when the isolation point is a valve wheel or oversized handle no padlock-and-hasp can span, step over to a cable lockout like the QWORK QS8899. For a complete personal device set in a pouch, the Brady 123143 kit bundles padlock, hasp, and tags together.

Category context

Three distinctions drive padlock selection. First, device type: a padlock holds a single isolation point per worker, a hasp lets multiple workers each apply their own lock to one isolation point for group lockout, and a kit or station stages all the devices together — a tag identifies the worker but is never itself an energy-isolating device. Second, keying: keyed-different (this pack) gives every worker a unique key for personal control, while keyed-alike puts one key across a matched set for a single tech covering several points; the trade-off is detailed in how to choose a lockout padlock. Third, personal vs group lockout: the 74/40 KD pack is built for the personal model under 1910.147, and you extend it to group work by adding hasps so several workers can lock the same point. See lockout vs tagout for why the lock — not the tag — is the controlling device.

Total cost of ownership

Total cost of ownership favors the 10-pack format: buying ten lockout padlocks at once is more economical per lock than singles and keeps your crew standardized, which is itself a 1910.147 durability-and-identifiability expectation. Thermoplastic bodies are corrosion-immune and light, lowering replacement from rust — though for high-impact or heavy-abuse settings a steel-bodied lock like the American Lock A1107R may outlast it. Factor in key control: with ten unique keys you'll need a managed duplicate-and-master process, ideally anchored at a lockout station. Budget for consumable tags alongside the locks, since tags wear and get replaced far more often than the padlocks they accompany. Across a multi-year program, the per-worker cost lands competitively against other crew 10-packs in our lockout/tagout range.

Final verdict

Buy the ABUS 74/40 10-pack when you're equipping an electrical maintenance crew that needs non-conductive personal locks, each keyed different, in one cost-effective order — that is its sweet spot and it earns a 4.6. If you instead need one key across multiple isolation points for a single technician, choose a keyed-alike lock like the ABUS 2ALHB/40-75. For pure budget crew issuance where dielectric properties aren't critical, the TRADESAFE TS1KD10R red 10-pack is a value alternative. For valve wheels and oversized handles, reach for a cable lockout, and for a turnkey single-worker bundle, the Brady 123143 kit.

ABUS 74/40 (10-Pack KD) FAQ

Is the ABUS 74/40 keyed different or keyed alike?

This pack is keyed different (KD): each of the ten locks has its own unique key, and no key opens another lock in the set. That is the correct configuration when every authorized worker must retain sole control of the only key to their own lock under 1910.147. If you need one key to open several locks, see the keyed-alike ABUS 2ALHB/40-75.

What does 'non-conductive' mean on this padlock, and is it rated for a voltage?

The 74/40 body is a non-conductive thermoplastic, which electrical crews favor for isolating energized circuits — it's a material property, not a published dielectric voltage rating. Treat it as supporting 1910.333 electrical work practices, and verify any specific voltage requirement against your own program. For comparison, several lockout padlocks use metal bodies that don't offer this property.

How many locks come in the pack, and who is that for?

It's a 10-pack — ten padlocks in one order, sized to equip a full maintenance crew at once rather than buying singles. Safety managers standardizing a team often prefer this format, the same logic behind the TRADESAFE TSKAU10YL yellow set. It keeps your lockout/tagout devices consistent across workers.

Does the ABUS 74/40 meet OSHA 1910.147 for lockout devices?

As a single-purpose, durable, identifiable padlock with per-worker keying, it fits the device requirements of 1910.147: lockout devices must be durable, standardized, substantial, and identifiable. The standard governs the program and procedure, not a product certification, so pair the lock with proper tags and a written procedure. See how to perform LOTO.

How does the 74/40 compare to the Brady SafeKey aluminum padlocks?

Both are non-conductive personal locks, but the 74/40 ships as a keyed-different 10-pack while the Brady SafeKey KD is sold as a single aluminum lock. Choose the ABUS pack to issue a whole crew at once; choose the Brady when you need one or a few individual locks. Both belong in the lockout padlock category.

Should I pick keyed different or keyed alike for my program?

Keyed different (like this pack) is the default for personal energy control — each worker's lock has a unique key. Keyed alike suits one technician managing several isolation points with a single key, as with the ABUS 2ALHB/40-75. Our guide on how to choose a lockout padlock walks through the decision.

Can I use the 74/40 for group lockout?

The padlock itself is a personal device, but you extend it to group lockout by adding a lockout hasp: the hasp holds one isolation point open while multiple workers each apply their own 74/40. That way every worker retains a unique key and the point can't be re-energized until all locks are removed. See lockout vs tagout for the device hierarchy.

Is a thermoplastic body durable enough for industrial use?

For typical indoor electrical and maintenance LOTO, yes — thermoplastic is corrosion-immune, light, and identifiable. For high-impact or heavy-abuse environments, a steel-bodied lock such as the American Lock A1107R may hold up better. Match the body material to your environment within the lockout/tagout range.

What's the difference between this padlock pack and a lockout kit?

This pack is ten padlocks only; a kit like the Brady 123143 bundles padlock, hasp, and tags in a portable pouch for a single worker. Buy the 10-pack to standardize a crew on identical locks; buy a kit to hand one worker a complete ready-to-use set. Both draw from the same lockout/tagout device family.

Does the standard shackle fit deep or stacked hasps?

The 74/40 has a standard shackle that handles typical hasps well, but it won't span deep or stacked hasps the way a long-shackle lock does. For those geometries, choose a long-shackle option from the lockout padlock range, such as the long-shackle ABUS 2ALHB/40-75.

Is a tag enough, or do I need the padlock too?

A tag identifies the worker but is not an energy-isolating device — it cannot physically prevent re-energization. The padlock is what holds the isolation point in the safe position, which is why lockout is preferred over tagout-alone under 1910.147. Use tags alongside, never instead of, the lock.

How does the 74/40 compare to a cable lockout?

A padlock secures a hasp or a lock-ready isolation point; a cable lockout like the QWORK QS8899 wraps flexible cable around valve wheels and oversized handles a rigid padlock can't span. Use the 74/40 for standard breakers and disconnects, and add cable locks for irregular geometry. Many programs stock both.

How should I manage ten unique keys?

With keyed-different locks, each worker keeps their own key, and duplicate or master keys must be controlled under a documented procedure — typically anchored at a lockout station. Build that key-control process before deployment so removal authority is clear. See how to perform LOTO for procedure structure.

Is the ABUS 74/40 a good value versus other 10-packs?

It commands a small premium over plain metal 10-packs because of the non-conductive body, which is worthwhile for electrical crews and unnecessary for non-electrical work. If you don't need the dielectric property, the TRADESAFE TS1KD10R red set is a budget alternative. Compare both in the lockout padlock range.

Can I use these locks for general security or padlocking gates?

No — these are single-purpose safety lockout padlocks, not general-security locks, and should be reserved exclusively for lockout/tagout energy control. Using LOTO padlocks for other purposes undermines the identifiability the standard depends on. Keep your safety padlocks dedicated to LOTO only.

Where do I start if I'm building a LOTO program from scratch?

Begin with what is lockout/tagout to understand the standard, then how to perform LOTO for the six-step sequence, and how to choose a lockout padlock to spec devices. A keyed-different 10-pack like the 74/40, plus hasps and tags, covers the core hardware for a crew.
