Master Lock MLS410YLW Padlock With permanent write-on labels 1-1/2" Xenoy

The Master Lock MLS410YLW is a padlock, keyed different with a 6-pin tumbler cylinder, with permanent write-on labels, 1-1/2 inch, Xenoy, yellow.

Note a listing inconsistency: this is the 410 series in yellow, and the blue and red versions in this catalogue are described as "Safety Lockout Padlock" while this one is described only as "Padlock." It is the same product family. The listing should say so, because someone searching for a lockout padlock will not find this one.

The 410 is a lockout/tagout lock, and that is a specific thing rather than a security product. A worker servicing equipment applies their own lock to the energy isolation device. It stops the machine being energised while they are inside it. Its resistance to attack is irrelevant — what protects the worker is procedure, plus the certainty that nobody else can open it.

Which is why keyed different is mandatory. One lock, one key, one worker, no master. A master key on a lockout system removes the protection entirely.

Xenoy is a non-conductive polymer, which matters at electrical isolation points.

The write-on label carries the worker's name — an unidentified lock on an isolation point halts a restart while everyone searches for its owner.

Yellow typically designates a specific department or energy type under a site's own scheme.

Applications include electrical, mechanical, and process lockout/tagout.
