Tooling U: Lockout/Tagout Practice

What is the purpose of the Occupational Safety and Health Administration (OSHA) standard for lockout/tagout?

• To ensure that all forms of energy are available during machine maintenance

• To define the different forms of energy used in manufacturing

• To provide minimum safeguards during service and maintenance

• To prevent the use of locks and warning tags in the workplace

What are the primary requirements to prevent accidental startup of machines according to the LOTO standard?

• Ensuring all machines are turned on before maintenance

• Placing locks and warning tags on energy isolation mechanisms

• Removing all forms of energy from the workplace

• Providing personal protective equipment to all employees

Which type of energy can cause shocks, burns, and fire hazards if it is accidentally restored during service?

• Hydraulic energy

• Pneumatic energy

• Electrical energy

• Kinetic energy

How do hydraulic and pneumatic energy differ from electrical energy when a machine is powered off?

• Hydraulic and pneumatic energy can still cause the machine to start unexpectedly

• Hydraulic and pneumatic energy dissipate immediately when the machine is powered off

• Hydraulic and pneumatic energy do not dissipate when a machine is powered off

• Hydraulic and pneumatic energy are only present when the machine is in use

What type of energy is usually produced by a reaction between two or more substances and can power machine components?

• Thermal energy

• Mechanical energy

• Chemical energy

• Kinetic energy

What can thermal energy in machine parts after shutdown be produced by?

• Only by electricity

• Only by chemical reactions

• Only by welding processes

• Chemical reactions, electricity, and processes like welding

Mechanical energy is the total amount of which two types of energy?

• Potential energy and chemical energy

• Kinetic energy and thermal energy

• Potential energy and kinetic energy

• Chemical energy and electrical energy

What does LOTO stand for?

• Lockout Tagout

• Lockout Turnoff

• Lockout Timeout

• Lockout Takeover

According to OSHA, what must an energy isolation mechanism be able to do?

• Be locked without dismantling, rebuilding, replacing, or permanently altering it

• Be operated remotely

• Be powered by multiple energy sources

• Be visible from a distance

What is the purpose of a lockout device?

• To improve the efficiency of energy use

• To hold an energy isolating mechanism in a safe position

• To increase the flow of energy

• To monitor energy consumption
