Lockout-Tagout of Meltric Plugs & Receptacles: DSN/DS/DR Series
Most MELTRIC plugs and receptacles facilitate compliance with OSHA lockout-tagout requirements. Only a lock or lockout hasp and tag are needed to ensure that the plug is properly locked out and tagged out. Additional mechanisms are not required because the lockout provision is integral to the device – it is always available when you need it. On most models the lockout provision is a simple 5/16” hole in the plug shroud that facilitates the insertion of a typical padlock or lockout hasp which prevents the plug from being inserted into a receptacle.
An optional provision for locking out MELTRIC receptacles is also available. In most cases this is accomplished via a specially machined hole in the receptacle casing which allows insertion of a padlock to secure the receptacle lid in a closed position. This same optional provision can be used to prevent removal of the plug if desired.
By comparison, in order to lockout most competitive pin and sleeve type plugs, an additional third-party ‘lockout shield’ or ‘plug cap’ is required. These devices can be expensive and are often times lost, broken, or not available when you need them.
