How to Choose a Safety Padlock

Safety Padlock General Characteristics
A safety padlock is meant to provide a measure of safety beyond that offered by a tag alone. Used properly in conjunction
with a well-planned lockout process, the safety padlock helps ensure that employees will not inadvertently energize a piece
of equipment while someone else is working on it.

The first rule in choosing a padlock for lockout is to ensure the lock looks different than those used in the facility for locking
toolboxes, gates, etc. This often is done by the use of bright colors. The most popular lockout padlocks have a "Danger"
label incorporated on them, which includes employee name, photo or both.

The second rule revolves around the mantra - "one employee, one key". This means all employees carry a unique key and no
one else's key can open the other employee's safety padlocks. A single employee may carry any number of padlocks, all
keyed to that same key for convenience (called KA - Keyed Alike), but no one else should have a key that can open
another employees' padlocks. This means that you should choose a padlock that offers enough unique key numbers to serve
all your current employees, with room for future growth. Master Lock offers 101,000 to over 1,000,000 key codes in the
410 and 411 Xenoy® padlocks. Aluminum padlocks offer 10,000 to 1,000,000 key codes. The laminated steel padlock
offers 1,400 codes.
Durability
A high security padlock is designed to keep a determined thief from prying, picking, cutting or hammering a lock off. While
providing a good level of security, safety padlocks are not specifically designed to provide resistance to physical attacks.
While providing a strong, durable lock is important - the most important consideration in safety lockout is that the keying
system used provides a large number of key choices and is not susceptible to key interchange. Key interchange is when
another person's key can accidentally open your lock. Master Lock uses high precision key cylinders in our Xenoy® and
aluminum safety padlocks.
Maintaining Safety Padlocks
Occasionally clean your safety padlock by blowing dust out of it. Apply a very light coat
of a greaseless lubricant like LPS1 to the keyway and where the shackle inserts into the
lock body. Do not use oil. Additional information is provided in Care & Maintenance.
Maximum Security
American Lock solid steel padlocks offer the highest protection of hardened steel.
Our padlocks come in a wide range of widths, with shackle lengths and diameters to
fit any application—great for outdoor protection of commercial buildings, industrial
plants and perimeters, remote or unattended properties and high risk areas.

• The strongest padlock available—hardened, triple plated steel bodies resist break-in
attempts, corrosion, rust and debris while the stainless steel double ball locking
mechanism further assures the lock’s strength and performance

• Hardened boron alloy shackles offer superior protection against cutting, while
serrated cylinder pins resist picking

• Rekeyable five- or six-pin cylinders can be keyed differently, alike, master
keyed or grand master keyed, with a variety of keyways
