Choosing the Right Safety Padlock for Your Workplace

A safety padlock is more than just a lock — it’s a crucial component of your workplace safety system. When used correctly as part of a structured lockout/tagout (LOTO) process, a safety padlock ensures that employees are protected from accidental equipment start-up while maintenance or servicing is in progress.

Master Lock offers a range of safety padlocks for industry best practice. Let’s explore the key considerations when selecting the right padlock for your needs.

Key Charted Systems: Secure and Organised Key Management

Proper key management is essential for maintaining a safe and efficient lockout system. Each employee should have a padlock with a unique key to prevent unauthorised removal of another worker’s padlock.

Types of Key Charting Systems:

• Registered Site: Ideal for large sites or businesses that want to prevent key duplication. Locks are made to order with key codes kept in a secure register by Master Lock.
• Non-Registered Site: Suitable for small-to-medium sites, these padlocks are supplied randomly from a pool of over 100,000 key codes.
   

Each registered site is assigned a unique ID number, which is emailed to a nominated contact.

Padlock Keying Options: Customisation for Your Needs

Master Lock provides various keying configurations to match different safety requirements:

• Keyed Different (KD): Each padlock has its own unique key, ensuring that no two locks open with the same key. This is the standard option for Master Lock safety padlocks.
• Keyed Alike (KA): Multiple locks can be opened with the same key, reducing the number of keys required. This is ideal when a single worker uses multiple padlocks.
• Master Keyed (MK): A master key allows supervisory access to all locks in a system, while individual workers still retain their unique keys.

Padlock Durability: Built to Withstand Harsh Conditions

Master Lock safety padlocks are designed to endure tough environments, including exposure to chemicals, debris, and extreme temperatures. Durable materials ensure long-lasting performance in demanding environments.

For example, the S31 safety padlock features a 4.76 mm stainless steel shackle, offering a high level of corrosion resistance while fitting smaller lockout points.

Master Lock’s lightweight, thermoplastic safety padlocks are suitable for use in diverse industries.

Requirements for Lockout Padlocks

Best practice suggests safety padlocks should meet the following criteria:

1. Durable: Locks should withstand environmental conditions without failure.
2. Substantial: Padlocks should resist removal without the correct key or excessive force.
3. Standardised: Locks should be uniform within a facility, based on colour, shape, or size.
4. Identifiable: Padlocks should have facility to indicate the employee who applied them — through an area for name, photo, or other identification such as laser engraving.
5. Exclusive for Safety: Safety padlocks should only be used for controlling hazardous energy — not for any other purpose.

Selecting the Right Padlock: Material, Shackle, Colour & Keying

Material: The right lock body material depends on its use environment. Choosing a padlock built for the conditions it will face ensures durability and compliance.

Shackle: Master Lock offers various shackle height and material options to suit different lockout applications.

Colour: Standardising padlocks by colour helps differentiate them within a facility. Assigning specific colours to departments for example provides visual safety as to who might be performing the lockout.

Keying: With multiple keying configurations available, you can select the option that best supports your workplace’s lockout/tagout safety protocol.
