Read it out loud

Free 5-minute toolbox talk

Read it out loud to your crew. It takes about 5 minutes.

Start with a question

Have you ever reached into a machine to clear a jam, even for a second, without locking it out?

Why it matters

Machines can start up without warning, and stored energy can be released even after the power is off. Lockout tagout keeps a machine from moving or releasing energy while someone is working on it. It only works when everyone follows the same steps, every time.

Key points

  1. Know your role: authorized or affected

    An authorized employee is the person who locks out or tags out a machine to service or maintain it. An affected employee runs that machine or works in the area where the servicing is being done.

    More

    An affected employee becomes an authorized employee when their duties include that servicing or maintenance.

    29 CFR 1910.147(b)

  2. Find every energy source

    Energy can be electrical, mechanical, hydraulic, pneumatic, chemical, thermal or another kind, and one machine can have several sources. Lockout goes on an energy isolating device, like a disconnect switch, a circuit breaker or a line valve.

    More

    Push buttons, selector switches and other control circuit devices are not energy isolating devices, so hitting the stop button is not lockout.

    29 CFR 1910.147(b)

  3. Follow the steps in order

    Lockout procedures must be done in the same sequence every time. Prepare and know the energy, shut the machine down, isolate it from its energy sources, put your lock or tag on, relieve, disconnect or restrain stored energy, then verify the machine is isolated and de-energized.

    More

    Skipping a step can get someone hurt.

    29 CFR 1910.147(d)

  4. Verify before you touch

    Before work starts, the authorized employee must verify that the machine is isolated and de-energized. A common check is to clear everyone from the area, try the normal start controls, then return them to off. Do not take anyone's word that it is dead.

    29 CFR 1910.147(d)(6)

  5. Restart the right way

    Before the locks come off, the work area must be checked for nonessential items, and everyone must be safely positioned or out of the way. Affected employees must be told the locks are off before the machine starts.

    More

    Each lock or tag is removed by the person who put it on, unless that person is not available and the employer directs its removal under a documented procedure that workers are trained on.

    29 CFR 1910.147(e)

  6. Respect every lock and tag

    A tag is a warning device. It does not physically hold a switch or valve off the way a lock does. A tag must never be removed without permission from the person responsible for it, and it must never be bypassed or ignored.

    More

    If you find a lock or tag, leave it alone, never try to start the equipment, and find out who owns it.

    29 CFR 1910.147(c)(7)(ii)

Scenario

Picture this: A conveyor jams near the end of a shift. The operator hits the stop button and reaches in to pull out a crushed box. Nobody has locked out the disconnect. At the far end of the line, a coworker who cannot see the operator presses start to check whether the line is clear. What should have happened before anyone reached in?

Ask the crew

  • Which machines in our area have more than one energy source, and where are their disconnects and valves?
  • Who on this crew is authorized to lock out, and who is affected?
  • What do you do if you find a lock or tag on equipment you need to use?
  • Where are our lockout procedures kept, and when did you last read the one for your machine?

Takeaway

Before you reach in, lock it out, try it, and keep your key until the job is done.

The rule

What OSHA requires

Plain-language summary. Each line links to the exact paragraph of the regulation.

  • The employer must set up an energy control program made up of energy control procedures, employee training and periodic inspections.

    “The employer shall establish a program consisting of energy control procedures, employee training and periodic inspections”

    29 CFR 1910.147(c)(1)

  • Energy control procedures must be developed, documented and used. A machine is exempt from the documentation part only when it meets every condition listed in the rule, such as having a single energy source.

    “Procedures shall be developed, documented and utilized for the control of potentially hazardous energy”

    29 CFR 1910.147(c)(4)(i)

  • Only the authorized employees who are doing the servicing or maintenance may apply lockout or tagout.

    “Lockout or tagout shall be performed only by the authorized employees who are performing the servicing or maintenance.”

    29 CFR 1910.147(c)(8)

  • Before starting work, the authorized employee must verify that the machine is isolated and de-energized.

    “the authorized employee shall verify that isolation and deenergization of the machine or equipment have been accomplished”

    29 CFR 1910.147(d)(6)

  • Each lock or tag must be removed by the employee who applied it. If that employee is not available, it may be removed only under the direction of the employer, using a specific removal procedure that has been developed, documented and trained on.

    “Each lockout or tagout device shall be removed from each energy isolating device by the employee who applied the device.”

    29 CFR 1910.147(e)(3)

  • Each authorized employee must be trained to recognize the hazardous energy sources, the type and magnitude of energy in the workplace, and the methods to isolate and control it.

    “Each authorized employee shall receive training in the recognition of applicable hazardous energy sources”

    29 CFR 1910.147(c)(7)(i)(A)

  • All other employees who work, or may work, in an area where lockout or tagout may be used must be told about the procedure and that attempts to restart or re-energize locked or tagged out equipment are prohibited.

    “the prohibition relating to attempts to restart or reenergize machines or equipment which are locked out or tagged out”

    29 CFR 1910.147(c)(7)(i)(C)

  • Where tags are used, workers must be trained that a tag is a warning device and does not physically restrain a switch or valve the way a lock does.

    “Tags are essentially warning devices affixed to energy isolating devices, and do not provide the physical restraint on those devices that is provided by a lock.”

    29 CFR 1910.147(c)(7)(ii)(A)

  • The employer must inspect the energy control procedure at least annually to make sure the procedure and the standard are being followed.

    “The employer shall conduct a periodic inspection of the energy control procedure at least annually”

    29 CFR 1910.147(c)(6)(i)

  • The lockout tagout standard does not cover construction and agriculture employment.

    29 CFR 1910.147(a)(1)(ii)(A)

Who must be trained

Every authorized employee must be trained to recognize hazardous energy sources, the type and magnitude of energy in the workplace, and how to isolate and control it. Every affected employee must be instructed in the purpose and use of the energy control procedure. All other employees who work, or may work, in an area where lockout or tagout may be used must be told about the procedure and that attempts to restart or re-energize locked or tagged out equipment are prohibited. (29 CFR 1910.147(c)(7)(i)(A) to (C))

When to retrain

Authorized and affected employees must be retrained when their job assignments change, when a change in machines, equipment or processes brings a new hazard, or when the energy control procedures change. Retraining is also required when a periodic inspection shows, or the employer has reason to believe, that a worker's knowledge or use of the procedures falls short. The employer must certify that training is done and kept up to date, with each employee's name and training dates. (29 CFR 1910.147(c)(7)(iii) and (c)(7)(iv))

Common questions

Questions people ask

Does OSHA require employers to establish a written energy control program?

Yes, the energy control procedures must be documented. OSHA requires an energy control program made up of energy control procedures, employee training and periodic inspections (29 CFR 1910.147(c)(1)), and the procedures must be developed, documented and used (29 CFR 1910.147(c)(4)(i)). The only exception to documenting them is a machine that meets every condition listed in that paragraph, such as a single energy source and no potential for stored or residual energy.

29 CFR 1910.147(c)(4)(i)

What goes in a written lockout tagout program?

The procedures must clearly and specifically outline the scope, purpose, authorization, rules and techniques for controlling hazardous energy, and how compliance is enforced. They must include a statement of intended use, steps for shutting down, isolating, blocking and securing machines, steps for placing, removing and transferring locks and tags, and requirements for testing that the controls work (29 CFR 1910.147(c)(4)(ii)). Each of these must be specific, not generic. The program also needs employee training and periodic inspections (29 CFR 1910.147(c)(1)).

29 CFR 1910.147(c)(4)(ii)

What should a LOTO awareness toolbox talk cover for workers who do not lock out?

Affected employees must be instructed in the purpose and use of the energy control procedure (29 CFR 1910.147(c)(7)(i)(B)). Everyone else who works where lockout may be used must be told about the procedure and that attempts to restart or re-energize locked or tagged out equipment are prohibited (29 CFR 1910.147(c)(7)(i)(C)). This talk covers the basics of both and what to do when you find a lock or tag, but it does not replace instruction on your site's own procedures.

29 CFR 1910.147(c)(7)(i)(C)
