Master Lock S33GRN Lockout Padlock Keyed Different Thermoplastic Green

Lockout Padlock for Safety Isolation

The Master Lock S33GRN is a thermoplastic padlock designed for lockout-tagout procedures in industrial and maintenance settings. Its green body and danger header provide clear visual identification of energy isolation points. The keyed-different cylinder ensures each lock opens only with its own key, supporting individual accountability. Workers securing machinery during service will find it fit for purpose.

Upgrading from Basic Padlocks

Standard padlocks lack the non-conductive body and dedicated safety labelling required by formal lockout programmes. Switching to this model adds a corrosion-resistant stainless steel shackle and a non-key-retaining mechanism that prevents the key from being removed while the shackle is open. The change is worth it when procedures demand documented energy control and distinct key codes per authorised person.

Limits of Thermoplastic Construction

The thermoplastic body resists chemicals and corrosion but does not withstand the same physical abuse as laminated steel or solid brass bodies. In environments with heavy impact, cutting tools or extreme heat the shackle and body may be compromised faster than metal alternatives. Users needing higher cut resistance or high-temperature tolerance should evaluate metal-bodied lockout devices instead.
