Lockout Tagout - Padlocks

What Padlock and Key do I need?
Padlocks are an essential part of a Lockout Tagout Programme, there are also various types of keying systems that can be used
as part of an e ective LOTO programme. Choose the type which is suitable for the intended process, bearing in mind its place
within the overall Lockout procedure.

Padlocks and Keying Systems
The correct keying system for your site will be dictated by LOTO procedures, identi ed through a LOTO audit. There are varying
options listed below:

Keyed Di erent (KD)
Each padlock can only be opened using a single unique key.

Keyed Alike (KA)
All padlocks in a Keyed Alike team have their own key. That same key can open any padlock within the same
team.

Master Keyed (MK) and Grand Master Keyed (GMK)
The padlocks in this system each have their own unique key, which can only open the corresponding padlock.

The Master Key for this team can open any of the padlocks within its own team. This can be further
extended over multiple teams, with a Grand Master Key able to open any padlock within any team.

Key Registering
other
A key registering system is recommended when issuing padlocks as part of a
planned Lockout Tagout programme and used correctly it can prevent duplicate
keys and improve safety. When registering your system you will be issued a unique
identi cation reference, by using this when ordering additional padlocks in the For Your Use Only
future we can ensure your keys will not be duplicated. Department
For Your Use Only
The additional use of key charting within your organisation will provide you with Name of Employee
the means to easily identify who the padlock and key has been issued to and when
it was issued. With the option of engraving padlocks and keys with a unique ID, key
charting can become even more e ective.

Ensure you order your padlocks from the same supplier and state
your Unique Identi cation Reference when ordering!

Engraving and Numbering
To reinforce a key registering
programme, safety padlocks can be
laser etched with names, registration
numbers, company details or other
identifying information.
