What is loto?
Loto is a method of safely isolating systems and equipment electrically and mechanically
What are the four main reasons for conducting loto?
The isolation of equipment to allow maintenance to proceed without hazard to the maintainer of the equipment
Where equipment is defective and may be dangerous
Prevention of selection of a mode which may be unavailable or dangerous
Where supplies have been provided but equipment has yet to be fitted
What are the seven considerations which must be conducted as part of the loto process?
All normal and alternative isolation points have been identified
Obtain permission from authorising technical rate
Equipment user and other personnel that may be affected are informed.
A separate loto form is to be filled in for each individual isolation point.
The next sequential number is to be identified from the loto log index
All details to be completed in front of the loto log
All the loto information is to be recorded on a loto safety certificate
