• To increase the speed of machine operations

What is the difference between Lockout and Tagout?

• Lockout involves placing a tag on the switch, while Tagout involves physically locking a switch or device

• Lockout and Tagout are not related to safety measures

• Lockout involves physically locking a switch or device, while Tagout involves placing a tag on the switch

• Lockout and Tagout are the same procedures

Why is Lockout Tagout important for worker safety?

• To provide warnings against hazardous conditions

• To prevent the use of padlocks

What do electrical plug lockouts do?

• Provide warnings against hazardous conditions

• Enclose the plug of electrical apparatuses, making them impossible to connect to a power outlet

• Secure wall switches in their current state

• Prevent circuit breakers from being reactivated

What should be done during the 'Shutdown' step of the Lockout Tagout procedure?

• Prepare for maintenance

What is the purpose of verifying the machine's status during Lockout Tagout?

• To check if the machine will start

• To increase the risk of accidents

• To ensure the machine is turned on

• To confirm that the machine will not start

What should be done to release stored energy during Lockout Tagout?

• Increase the energy flow

• Ignore the energy sources

• Relieve, disconnect, restrain, block, or ensure all energy sources are de-energized

• Activate all energy sources
