Brady Lockout Padlock 99580: Compact Lock, Serious Safety

2025-12-22T02:37:05Z

In every plant, workshop, or facility, there are tools and machines that can change someone’s life in a split second. That’s why safety procedures are non‑negotiable, and why the Brady lockout padlock 99580 has become a trusted piece of hardware in many lockout/tagout programs. It may look like a simple safety padlock, but behind its nylon body and steel shackle is a design built for reliability, accountability, and compliance.

Whether you manage a large industrial site, look after a small maintenance team, or you’re just tightening up your lockout/tagout (LOTO) procedures, understanding how the Brady lockout padlock 99580 works—and how to use it well—can make a visible difference in safety culture.

In this in‑depth guide, we’ll walk through what makes the Brady lockout padlock 99580 unique, its technical specifications, how it supports OSHA‑aligned LOTO programs, where it fits best, and how to combine it with compatible accessories for a complete solution.

What Is the Brady Lockout Padlock 99580?

The Brady lockout padlock 99580 is a standard safety padlock designed specifically for lockout/tagout applications, not for securing doors, gates, or general security use. It has a rugged black nylon body paired with a hardened steel shackle, giving you a combination of electrical safety, chemical resistance, and mechanical strength.

Unlike everyday padlocks, the Brady lockout padlock 99580 is built around one key safety principle: one worker, one lock, one key. It’s typically supplied keyed different, meaning each padlock has a unique key code. That uniqueness is essential in LOTO, where each padlock represents the personal protection of a single authorized employee working on a machine or system.

The Brady lockout padlock 99580 is also key‑retaining. The key cannot be removed while the shackle is open. This prevents common mistakes like leaving a lock hanging unlocked or walking away without properly securing the isolation point. The lock body is non‑conductive and spark‑resistant, so it’s especially suited for electrical environments when used together with the correct lockout devices.

In short, the Brady lockout padlock 99580 is not a general security product—it is a purpose‑built safety device that supports a structured, auditable lockout/tagout process.

Technical Specifications of the Brady Lockout Padlock 99580

For engineers, safety officers, and procurement teams, the details matter. The Brady lockout padlock 99580 comes from Brady’s LOTO‑8 nylon safety padlock family, designed with consistent dimensions and performance across colours and keying options.

Physical dimensions

The Brady lockout padlock 99580 uses a compact but easy‑to‑handle body size:

Body height: 1.75 in (≈ 44.5 mm)
Body width: 1.50 in (≈ 38.1 mm)
Body thickness: 0.82 in (≈ 20.8 mm)
Shackle diameter: 0.25 in (6.35 mm)
Shackle vertical clearance: 1.50 in (38.1 mm)
Shackle horizontal clearance: 0.80 in (≈ 20.3 mm)

These proportions let the Brady lockout padlock 99580 fit comfortably through standard lockout hasps, breaker lockouts, and valve lockout devices without being bulky or heavy for technicians who carry multiple padlocks on their belt or in a pouch.

Materials and construction

The body of the Brady lockout padlock 99580 is made from fiberglass‑reinforced Nylon 66. This material is:

Non‑conductive
Spark‑resistant
Lightweight
Resistant to many industrial chemicals and corrosion

The shackle of the Brady lockout padlock 99580 is hardened steel, typically triple‑coated for enhanced corrosion protection. That gives you mechanical strength where it matters—at the isolation point—while the insulated body helps protect workers around electrical hazards when used correctly.

Environmental performance

The Brady lockout padlock 99580 is rated for a typical service temperature range of 0 °F to 250 °F (about ‑18 °C to 121 °C). This wide range allows the padlock to perform reliably in cold storage, standard plant conditions, and many warm process environments.

The nylon body used in the Brady lockout padlock 99580 provides durability for indoor and outdoor applications, with good resistance to moisture, humidity, and weathering when used within its recommended limits.

Keying system and security

Internally, the Brady lockout padlock 99580 uses a six‑pin cylinder for improved tamper resistance compared to simpler padlocks. Across the LOTO‑8 padlock family, Brady can supply thousands of unique key codes, which supports structured key management in large facilities.

Key characteristics of the Brady lockout padlock 99580 include:

Keyed different: Each padlock has a unique key by default.
Key‑retaining: The key can only be removed when the shackle is fully closed and locked.
6‑pin cylinder: Provides greater resistance against casual picking or unauthorized duplication.

This combination means each Brady lockout padlock 99580 is easy to manage as the personal lock of a single worker, helping you maintain clear accountability in your lockout/tagout program.

Labelling and identification

Labelling is a core part of lockout/tagout. The Brady lockout padlock 99580 is typically supplied with multi‑language safety labels that carry a clear warning message and space for worker identification.

These labels often include a bold DANGER header and wording such as “Locked Out – Do Not Remove” along with a field where workers can write their name, department, or contact details. That makes every Brady lockout padlock 99580 not just a piece of hardware but a visual statement: this machine is locked out for a reason, and only the named person may remove the lock.

How the Brady Lockout Padlock 99580 Supports OSHA‑Aligned Lockout/Tagout

A key reason many facilities choose the Brady lockout padlock 99580 is that it fits neatly into a structured energy‑control program. While the padlock itself doesn’t “certify” compliance, its design supports core lockout/tagout principles found in standards like OSHA 29 CFR 1910.147.

Personal control and accountability

LOTO standards emphasise that each authorized employee must apply their own lock to each isolation point they are working on. Because the Brady lockout padlock 99580 is keyed different and key‑retaining, it naturally supports this. Only the worker holding the key can remove the lock, and they cannot walk away with the key unless the lock is fully closed.

This means the Brady lockout padlock 99580 helps enforce personal control over hazardous energy, ensuring no one can re‑energize equipment while maintenance or servicing is underway.

Durability and standardisation

Standards also require lockout devices to be durable, standardized, and easily identifiable. The Brady lockout padlock 99580 checks all three boxes:

Durable: Rugged nylon body and coated steel shackle designed to withstand harsh industrial environments.
Standardised: Consistent size, style, and construction across the LOTO‑8 family of padlocks.
Identifiable: Distinctive black colour and clear lockout labels make each Brady lockout padlock 99580 stand out from ordinary security locks.

This consistency makes it easier for your teams to recognise a LOTO device at a glance.

Electrical safety context

Although the body of the Brady lockout padlock 99580 is non‑conductive and spark‑resistant, it is not a substitute for proper electrical PPE or system design. What it does offer is an extra layer of protection when used with appropriate electrical lockout devices, such as breaker lockouts or disconnect handle lockouts.

By combining these devices, you can build an electrical isolation strategy where the Brady lockout padlock 99580 is the final step that physically prevents the device from being operated.

Typical Applications for the Brady Lockout Padlock 99580

Because of its size, construction, and performance, the Brady lockout padlock 99580 adapts well to a wide range of industries and tasks.

Whenever you need to secure an energy‑isolating device and clearly show that equipment is off‑limits, the Brady lockout padlock 99580 becomes a simple, visible safeguard.

Alternative Options to the Brady Lockout Padlock 99580 (Same Platform)

One of the strengths of Brady’s LOTO‑8 padlock family is that you can standardise on a single form factor while adapting colours and keying schemes to your site’s rules. The Brady lockout padlock 99580 is the black‑body version of this family.

If you like the performance of the Brady lockout padlock 99580 but need other colours or configurations, there are many direct alternatives using the same design.

Same body size, different colours

Brady’s LOTO‑8 padlocks are available in several colours, all sharing the same dimensions and core specs as the Brady lockout padlock 99580:

Red body, keyed different (commonly used for general maintenance)
Blue body, keyed different (often used for electrical teams)
Green body, keyed different (sometimes used for safety supervisors)
Yellow, purple, and other colours for departmental or functional coding

This means you can deploy the Brady lockout padlock 99580 for specific roles (for example, black for contractors or supervisors) while maintaining compatibility with your existing lockout devices.

Keyed‑alike and master‑key options

For some applications, you may need multiple padlocks that open with the same key. Brady offers keyed‑alike versions of the same LOTO‑8 padlock design, so you can combine the Brady lockout padlock 99580 with matching units that share a key where appropriate.

Keyed‑alike sets simplify key management when a single worker must apply several locks across a machine or line. In larger facilities, master‑key systems can be configured under controlled conditions so safety coordinators can open locks in genuine emergencies without breaking hardware.

The important point is that you can build a fully structured padlock hierarchy without losing the familiar form factor of the Brady lockout padlock 99580.

Accessories that Work with the Brady Lockout Padlock 99580

On its own, the Brady lockout padlock 99580 is a robust lock. But it becomes much more powerful when combined with other lockout devices designed around the same shackle diameter and clearances.

Common accessories that pair well with the Brady lockout padlock 99580 include:

Lockout hasps

Lockout hasps are metal or non‑conductive devices that allow multiple padlocks to secure the same isolation point. The Brady lockout padlock 99580 is often used with standard steel or aluminium hasps that accept a 6.35 mm (¼") shackle.

Using a hasp, each authorized worker applies their own Brady lockout padlock 99580, and the energy source cannot be re‑energised until every padlock has been removed. This enforces true group lockout protocols.

Circuit breaker lockouts

For electrical panels and distribution boards, breaker lockouts are designed to clamp onto miniature or moulded‑case circuit breakers. The Brady lockout padlock 99580 is then applied through a dedicated hole in the device, preventing the breaker handle from being switched back on.

Because the Brady lockout padlock 99580 has a compact shackle and body, it fits easily on these devices without obstructing other breakers or labels.

Valve lockouts

Ball, gate, and butterfly valve lockouts physically block the valve handle or stem in the OFF or closed position. The Brady lockout padlock 99580 secures these lockouts in place, ensuring manual valves cannot be opened accidentally during maintenance.

Where multiple teams are involved, several Brady lockout padlock 99580 units can be added via hasps or multi‑hole lockout brackets.

Cable lockouts

Cable lockout devices use a flexible cable to secure multiple isolation points or hard‑to‑reach mechanisms. Once the cable is tensioned and locked, the Brady lockout padlock 99580 is used to secure the mechanism so it cannot be loosened.

This makes the Brady lockout padlock 99580 useful on irregular equipment where a standard clamp‑on device may not be enough.

Storage and padlock stations

To keep everything organised, many facilities use wall‑mounted padlock stations or carry pouches. The Brady lockout padlock 99580 is frequently included in complete Brady lockout kits, where it lives alongside hasps, tags, and a small selection of universal lockout devices.

Storing each Brady lockout padlock 99580 in designated slots on a station can also simplify audits, as it’s easy to see which locks are checked out and by whom.

Best Practices and Mounting Tips for the Brady Lockout Padlock 99580

Choosing the right padlock is only half the job. To get the most value from the Brady lockout padlock 99580, your lockout/tagout procedures should be clear, consistent, and easy for your teams to follow.

1. Integrate the padlock into a written procedure

Every lockout operation should follow a written, equipment‑specific procedure. Make sure the Brady lockout padlock 99580 is explicitly mentioned in your documents as the required personal safety lock.

When workers can see where and how to apply their Brady lockout padlock 99580 on each disconnect switch, breaker, or valve, they are far more likely to follow the process correctly.

2. Use clear identification on every padlock

Even though the Brady lockout padlock 99580 is supplied with labels, it’s good practice to add extra identification where needed. This can include:

Worker’s name and photo
Department or team
Unique lock number tied to your lock registry

When every Brady lockout padlock 99580 is clearly owned, there’s no confusion about who is responsible for removing it and when.

3. Follow the standard LOTO sequence

A typical sequence using the Brady lockout padlock 99580 will look like this:

Prepare for shutdown: Identify all energy sources feeding the equipment.
Notify affected employees: Let operators and nearby staff know that lockout is about to start.
Shut down equipment: Use normal stop controls.
Isolate energy: Open disconnect switches, circuit breakers, valves, or other isolating devices.
Apply lockout devices: Install the appropriate lockout hardware on each isolation point.
Apply the padlock: Pass the shackle of the Brady lockout padlock 99580 through the device and lock it. Confirm the key is retained only when the shackle is closed.
Tag the lock: Attach a tag or label with your details and the reason for lockout.
Verify isolation: Attempt a "try start" to confirm the machine cannot run.

Only after all work is complete, all guards are in place, and all workers are clear should each person remove their Brady lockout padlock 99580 and return the equipment to normal operation.

4. Standardise colours and keying

If your site uses multiple colours of the same padlock design, decide where the Brady lockout padlock 99580 fits into that system. For example:

Black: Supervisors or external contractors
Red: General maintenance
Blue: Electrical work
Green: Safety or EHS personnel

By assigning a clear meaning to each colour, you make it easier to interpret what’s happening at a glance and to manage inventories of Brady lockout padlock 99580 units alongside their coloured counterparts.

5. Inspect and maintain regularly

Although the Brady lockout padlock 99580 is built for durability, it still needs periodic checks—especially in harsh or corrosive environments.

Include the Brady lockout padlock 99580 in your regular inspection routine:

Ensure the shackle locks and unlocks smoothly.
Check for damage to the plastic body or labels.
Look for corrosion on the steel shackle, particularly in wash‑down or outdoor locations.
Replace any Brady lockout padlock 99580 that shows visible damage or that no longer operates cleanly.

These simple checks help you avoid failures at critical moments and extend the working life of your safety padlocks.
