Safely lock out electrical equipment—these padlocks are made entirely out of plastic, so they don't conduct electricity. Unlike metal padlocks, they’re nonmagnetic and won’t spark. They come in a variety of colors that grab your attention and display a warning label that signals a machine is locked out. To meet lockout identification standards, assign colors to individuals or functions, such as red for electrical and blue for plumbing. Pair them with a hasp, chain, or another lockout device to meet OSHA 29 CFR 1910.147 procedures to prevent accidental startups.

These padlocks have a pin-tumbler key locking mechanism, which is the most difficult locking mechanism to pick. The more pins a lock has, the harder it is to pick. Choose them if you need locks that each open with a different key. All locks have random key numbers.
