Brady SafeKey ALU-PRP-38ST-KD Lockout Padlock — Aluminum Purple

The Brady SafeKey ALU-PRP-38ST-KD lockout padlock in purple gives facilities running multi-trade LOTO color-coding programs a distinct, high-visibility color assignment for a specific department, shift, or contractor group. Purple is increasingly adopted in sophisticated LOTO programs as the sixth or seventh color in a palette that has already assigned red, blue, yellow, orange, and green to other trades. Brady's SafeKey anodized aluminum construction ensures the purple color is permanent — not a surface coat that chips or fades — while the 1.5" hardened steel shackle and keyed-different configuration deliver full OSHA 29 CFR 1910.147 personal-lock compliance.

Product Specifications

Detailed Description

Color-coded lockout/tagout programs succeed when every authorized employee can identify at a glance which locks on a hasp belong to which trade or department — and when that identification is unambiguous even under poor lighting, at a distance, or in a busy shift-change audit. Brady SafeKey's color palette supports exactly this kind of program, and purple is the color that allows facilities with the most complex multi-trade environments to extend their color-coding system to a sixth or seventh distinct assignment without running out of visually distinguishable options.

Consider a large petrochemical complex with simultaneous maintenance activities from electrical contractors, mechanical contractors, process operators, instrumentation technicians, insulation contractors, and scaffold crews — each of whom may be locking out the same isolation points on shared equipment during a turnaround. Red, blue, yellow, orange, and green are already assigned to the first five trades. Purple becomes the sixth distinct, unambiguous assignment that makes visual audits possible without reading every individual lock tag under time pressure.

Brady SafeKey's color anodizing process is the underlying technology that makes this reliable at scale. The anodizing penetrates the aluminum surface rather than coating it, which means the purple color on an ALU-PRP-38ST-KD lock issued today will remain clearly purple after three to five years of daily industrial use. Paint or powder-coat finishes on competitor locks chip, scratch, and fade — leaving locks that started as purple looking ambiguously similar to a blue or gray lock after extended field service. In a program where visual identification is the primary audit tool, color permanence is a compliance requirement, not just an aesthetic preference.

The keyed-different configuration means every purple lock in your inventory has its own unique key code. Workers in the designated purple-color department each receive a lock they alone can remove. The same personal-protection principle that governs any LOTO program applies fully: one worker, one key, one lock. The color identifies the department. The individual key identifies the specific worker.

The laser-engravable body surface allows personalization at issuance. Facilities with mature LOTO programs engrave each lock with the worker's name or employee ID, creating a direct chain of custody from the safety manager's issuance records to the lock body itself. This satisfies OSHA's identifiability requirement at the physical device level — which is more robust than relying on a paper tag that can fall off or become illegible.

The 1.5" hardened steel shackle fits the vast majority of standard safety hasps and lockout hardware. The ALU-PRP-38ST-KD integrates fully with Brady's SafeKey lockout station ecosystem, including wall-mounted stations, personal LOTO pouches, and shadow-board layouts that accommodate multiple SafeKey colors simultaneously for visual control of your LOTO program inventory.

Compliance and Standards

• OSHA 29 CFR 1910.147 — Control of Hazardous Energy (Lockout/Tagout)
• Meets OSHA standardization requirements: consistent color within facility LOTO program
• Compatible with NFPA 70E and CSA Z460 lockout requirements
• Laser-engravable body supports OSHA identifiability requirements without relying on attached tags

Real-World Benefits

EHS managers at large petrochemical, power generation, and heavy manufacturing facilities who run multi-color LOTO programs report that adding purple to their color palette eliminates the last remaining color conflicts in their most complex contractor coordination scenarios. Rather than assigning two trades the same color and relying on tag differentiation alone, a purple assignment gives each trade a uniquely recognizable visual signature from 20 feet away.

Turnaround coordinators in process industries find that Brady SafeKey's consistent color anodizing makes end-of-turnaround hasp audits significantly faster. Verifying that every purple lock (instrumentation crew) has been removed before re-energization is a visual count rather than a lock-by-lock tag reading — reducing audit time and the risk of a missed lock at the end of a complex maintenance event.

Applications and Use Cases

• Instrumentation and controls technicians assigned purple in a 6-color LOTO program
• Specialty contractor groups requiring a distinct color separate from red, blue, yellow, orange, and green
• Large turnarounds and shutdowns with six or more concurrent trades on the same equipment
• Facilities expanding an existing color-coded LOTO program to include additional departments or contractors
• EHS managers issuing personalized locks to newly authorized employees in purple-assigned departments
• Replacement locks for workers whose purple SafeKey was lost or damaged during maintenance activities

Frequently Asked Questions

How many colors does Brady SafeKey offer for aluminum LOTO padlocks?

Brady SafeKey aluminum lockout padlocks are available in red, blue, yellow, orange, green, and purple — six distinct colors for multi-trade color-coding programs. Each color is available in both keyed-different (KD) and keyed-alike (KA) configurations to support both personal-lock and supervisor/group-lock use cases.

What department or trade is typically assigned purple in a LOTO color-coding program?

There is no OSHA-mandated color assignment for any trade. Facilities choose their own assignments documented in their written LOTO program. Purple is frequently assigned to instrumentation and controls technicians, specialty contractor crews, or the sixth trade in a complex multi-trade environment where five other colors are already in use. What matters is that your written program documents the assignment and all authorized employees are trained on it.

Is the purple color permanent on Brady SafeKey padlocks?

Yes. Brady uses a color anodizing process that penetrates the aluminum surface rather than applying a surface coat. The purple color will not chip, peel, scratch off, or fade over the typical service life of the lock under normal industrial conditions. This is a key advantage over painted or powder-coated alternatives in a program that relies on color for visual identification.

Can I order purple SafeKey locks keyed-alike for a supervisor?

Brady offers SafeKey aluminum padlocks in keyed-alike configurations across all colors, including purple. A keyed-alike purple set allows a supervisor or turnaround coordinator to hold one key that opens all purple locks assigned to their crew — useful for end-of-event audits and emergency lock removal under documented exception procedures.

What is the difference between the purple SafeKey (ALU-PRP-38ST-KD) and the blue SafeKey (ALU-BLU-38ST-KD)?

The only difference is the anodized body color — purple versus blue. Both are keyed-different, aluminum body, 1.5" hardened steel shackle, and OSHA 1910.147 compliant. The color difference is the entire point: they are interchangeable in terms of construction and compliance, but visually distinct for color-coding program purposes.

How do I build a complete multi-color LOTO program using Brady SafeKey?

Start by documenting your color assignments in your written LOTO program (which trade or department gets which color). Issue personal keyed-different locks in the assigned color to each authorized employee. Store locks on a Brady SafeKey wall station with color-coded shadow boards for each department. Maintain a key-code registry mapping each lock's key code to the named employee who holds it. Review and update assignments when personnel or contractors change.

Does the ALU-PRP-38ST-KD fit all standard safety hasps?

Yes. The 1.5" shackle and 40mm body are compatible with standard North American safety hasps from Brady, Master Lock, ABUS, and American Lock. The aluminum body is the same form factor as all other Brady SafeKey padlocks, so it fits the same stations, pouches, and hasp configurations used for other SafeKey colors.
