Q- 6: Define LOTO

Lockout/Tagout Certificate –means to provide a safe environment for performing maintenance, repair or replacement operations on process facilities by disconnecting or separating the energy sources, to protect the people and equipment. Isolation can apply in the following ways.....

Types of isolation

Ø  Mechanical/Process isolation

  • ·        Physical disconnection-removal of pipe section by using blind flange.
  • ·        Blinding/Blanking-different types of blinding like spade & spacer, spectacle blind, blind flange etc...)
  • ·        Double block & bleed (bleed means vet & drain)-shutting two isolation valves and opening a bleed valve.
  • ·        Double block- If double block with bleed isolation is not possible, double block isolation only could be acceptable with the required precautions, if backed (Samaritan) by the risk assessment.
  • ·        Single block & bleed-used only when the reasonable possible alternative and the risk is acceptable.

Ø  Electrical isolation-LOTO - electrical, valve, telecommunication, energy sources include mechanical, hydraulic, and pneumatic (air), chemical, thermal, radioactive, gravity etc...

LOTO is a safety procedure used in industry to ensure that dangerous machines are properly shut off and not able to be started again before the completion of maintenance or repair work.
