What Does Loto Mean In Safety
– Answer – LOTO (Lock Out Tag Out) is the physical restraint of all hazardous energy sources that supply power to a piece of equipment, machinery or system. LOTO also includes applying a Warning Tag on the physical restraint device. This documents the Authorized LOTO personnel and the date.

LOTO operations must be done on all equipment, machinery or system Shut Downs before Authorized Personnel can perform repairs or service. Most equipment and machinery has an Energy Isolation Device. These devices are usually put into the off position to shut down the hazardous energy source. Physical restraints (Lock Out Devices) can be put onto the Energy Isolation Device and secured with padlocks.

Examples of Lock Out Devices include: ball valve and gate valve lock outs, circuit breaker lockouts, plug and wall switch lock outs and pneumatic lock outs. The total shutdown and restraint of all hazardous energy sources including the safe release of stored hazardous energy (e.g.

What is an example of LOTO?

What is a Lockout Device? – A lockout device is a device that utilizes a positive means to hold an energy isolating device in a safe position and prevents the energization of equipment and machinery. Examples of lockout devices are padlocks, blank flanges, and bolted slip blinds. Lockout Device A LOTO padlock should only have one key. Lockout locks should not be keyed alike, in which multiple padlocks can be opened with one key. If the use of keyed alike locks cannot be avoided, limit their distribution among employees.

When should LOTO be used?


Lockout/Tagout is required when the unexpected energization or start up (or release of stored energy ) of machines, equipment or prime movers could injure workers during cleaning, repairing, servicing, setting-up, adjusting and un-jamming.

Who can remove LOTO?

Lockout or tagout device removal: Each lockout or tagout device must be removed from the energy-isolating device by the employee who applied the device.

Does LOTO eliminate the hazard?

August 28, 1995 William K. Principe Constangy, Brooks & Smith Suite 2400 230 Peachtree Street, N.W. Atlanta, Georgia 30303-1557 Dear Mr. Principe: This letter is in response to the questions in your letter of January 3, 1995. The questions and responses are as follows: Q 1.

  • Is compliance with the Lockout/Tagout Standard 29 CFR 1910.147, sufficient to demonstrate that possible energization is no longer a hazard and that, as a consequence, a permit-required confined space can be classified as a non-permit required confined space? R.
  • A permit-required confined space can be reclassified as a non-permit required confined space if it does not contain any actual or potential hazardous atmosphere and all hazards within the space are eliminated.

For the purpose of reclassifying a permit-required confined space, which has potential energy sources in it, the methods which must be utilized are dependent upon what types of energies must be eliminated. Compliance with OSHA’s Lockout Tagout Standard is considered to eliminate electro-mechanical hazards.

However compliance with the requirements of the Lockout/Tagout Standard is not considered to eliminate hazards created by flowable materials such as steam, natural gas, and other substances that can cause hazardous atmospheres or engulfment hazards in a confined space. In a permit-required confined space these types of hazards will be considered eliminated only by the use of the techniques described in the definition of the term “isolation”.

The definition of the term “isolation” is in paragraph (b) of 29 CFR 1910.146. The techniques listed in the definition are blanking, blinding, misaligning or removing sections of lines or pipes and a double block and bleed system. Q 2. Does the implementation of an appropriate lockout procedure which blocks out a potentially hazardous atmosphere, allow an employer to treat a confined space as not having a potential for an atmospheric hazard? R.

  • No. As indicated in the response to the first question flowable materials, which can cause either a hazardous atmosphere or an engulfment hazard, can only be eliminated by the use of the techniques described in the definition of the term “isolation”.
  • Continuous ventilation used to insure that a hazardous atmosphere is not created is considered to be a control method rather than elimination of the atmospheric hazard.

It is important that the distinction between elimination and control be understood. Q 3. For permit-required confined spaces that have been reclassified as non-permit required confined spaces, can continuous monitoring be used to ensure that atmospheric hazards remain eliminated? R.

  • Such a procedure should not be necessary if the atmospheric hazard is eliminated.
  • In order for a permit-required confined space, with an actual or potential atmospheric hazard, to be reclassified as a non-permit required confined space the atmospheric hazard must be eliminated. Q 4.
  • Under paragraphs (c)(5)(i) and (c)(5)(ii) of 29 CFR 1910.146 can continuous monitoring be used in lieu of continuous forced air ventilation if no hazardous atmospheric is detected? R.

No. The entire basis for the permitting the alternate entry procedures, described in paragraph (c)(5) of 29 CFR 1910.146, is that any actual or potential hazardous atmosphere will be controlled by continuous ventilation. This is of particular significance since among other things the alternative procedures do not require the presence of an attendant during entry operations.

Entrants could be severely injured or killed if a hazardous atmosphere does develop and there will be no one available to aid them in getting out of the space. In addition to the preceding questions there were several issues raised in the examples in your letter relative to three different permit-required confined spaces.

Those issues are addressed in the following paragraphs. Two different procedures must be implemented in order to reclassify the tank, described in example “a” of your question 4, as a non-permit required confined space. The hazard associated with the agitator will be considered to be eliminated if the requirements of the Lockout/Tagout Standard are followed.

The hazard associated with the dump valve, if the result of a release from the dump valve will be a hazardous atmosphere or engulfment hazard, must be eliminated by utilizing the techniques described in the definition of the term “isolation”. See the response to questions number one and two for further clarification of requirements related to elimination of hazards.

The tank described in your example “b” cannot be entered under the alternative procedures permitted by paragraph (c)(5) unless continuous ventilation is provided. Additionally, the alternative procedures described in paragraph (c)(5) can be implemented in permit-required confined spaces in which the only hazard is an actual or potentially hazardous atmosphere.

If the input or output for the dry material can cause or permit material to enter the tank and create an engulfment hazard the techniques described in the definition of the term “isolation” must be used in order for the hazard to be considered eliminated. See the response to question number three for further information relative to use of the alternative procedures.

The underground vault/pit described in your example “c” cannot be reclassified as a non-permit required confined space unless all the hazards associated with the space are eliminated. Since the only hazards in that space seem to be either atmospheric hazards or engulfment hazards the procedures described in the definition of the term “isolation” must be used to eliminate the hazards.

  1. Underground vaults/pits have the potential for actual or potential hazardous atmospheres.
  2. Contaminants can enter such spaces and certain chemical reactions, such as oxidation, which can deplete the oxygen in such spaces.
  3. If atmospheric hazards cannot be eliminated and continuous ventilation is used to control them the procedures set forth in paragraph (c)(5) must be followed.

As indicated in the response to question number two water is not considered to be an atmospheric hazard. Water in a permit-required confined space such as a pit can be an engulfment hazard or a hazard because it creates or conceals other unsafe conditions.

If water in a permit-required confined space presents an engulfment hazard then the procedures described in the definition of the term “isolation” must be utilized. If you require any additional information regarding the preceding, please contact Don Kallstrom by telephone at (202) 219-8031. Sincerely, John B.

What are common LOTO violations?

Types of OSHA Violations – There are six different types of violations that OSHA can issue fines for:

Other Than Serious violations – violations that create unsafe situations that are not likely to harm employees. Serious violations – violations that pose a significant threat to the employee, often resulting in death or maiming. Serious violations can be fined up to $70,000 per incident, though if companies work to correct the issue, the fine may be reduced. Willful violations – violations that intentionally breach OSHA standards. These can be fined up to $70,000 if no injuries or deaths occur. If an employee is injured or killed due to a willful violation, the company will face criminal charges and a fine of $250,000. Not having a lockout/tagout program is a common example of this type of violation. Repeat violations – Repeat violations are violations that have been previously fined, but are just different enough to be a new violation. These violations can be fined up to $70,000. Failure to Abate violations – violations that have been previously fined that the company has not corrected. These violations can be charged up to $7,000 per day until the situation is resolved. De Minimus violations – violation that are considered minor violations that are not fined, but will be included in an investigation.

Common LOTO-related violations include not having an accessible procedure or placard for each piece of equipment that needs it and improper training/lack of training for employees. If it’s not already clear, you want to avoid employee injuries and OSHA fines at all costs – not only can it be a PR nightmare, but the fines themselves are never part of the annual safety budget.

What is the minimum voltage for LOTO?

Lockout/Tagout (LOTO) 2017 LOTO Program Revision Pub-3000, Chapter 18 revision is now in full effect, as of March 31, 2017! This is a minor revision to the LOTO Program. The intent is to match efforts in the Electrical Safety Program (ESP) revision to streamline requirements for Qualified Electrical Workers (QEWs) and electrical work, and it also includes a few editorial corrections.

The revised describes our institutional requirements and processes to ensure proper control of hazardous energy. To review just the primary changes to the document, view the Analysis of Changes powerpoint below:

What is Lockout/Tagout (LOTO)?

  1. LOTO is a formal process for controlling hazardous energy.
  2. LOTO protects personnel working on equipment from the unexpected release of hazardous energy.
  3. Lockout/Tagout (LOTO) is composed of two principal process components:
    • Deenergization removes all energy sources from the system.
    • Control prevents re-energization.

For more information on the general principles of LOTO, please read in the ES&H LOTO Program. When is LOTO required? LOTO is generally required for all servicing and maintenance of equipment that has the potential to cause injury. This also includes construction and demolition.

More specifically, certain programs define hazardous energy thresholds that trigger the application of LOTO. For example, electrical line voltage above 50 VAC is considered hazardous and requires LOTO whenever a person is closer than 42 inches of exposed electrical circuit parts (750V and less). Who is required to LOTO? Each and every person who is performing work on the equipment or who is entering an area with hazards controlled by LOTO, is required to apply their personal LOTO lock and tag.

This requirement for personal LOTO is essential. Berkeley Lab employees who participate in LOTO must have completed the following training course: EHS0370 – Lockout/Tagout for Authorized Persons, Click the Sign up for Training link on the left sidebar to register for training.

  1. Subcontractors who participate in LOTO must complete EHS0379 – Lockout/Tagout Orientation for Subcontractors, have a designated LOTO Responsible Individual, and have an approved Subcontractor LOTO Permit.
  2. For non-construction subcontractors and vendors, this is initiated and coordinated through the,

Do LOTO locks have to be red?

Acceptable Locks – A major requirement of OSHA’s Control of Hazardous Energy regulation (1910.147), is the use of protective materials and hardware during lockout. OSHA requires that all locks must be:

Provided by the employer Singularly identifiable for lockout use only, with an indication of which authorized employee is using them Not used for any other purpose other than lockout/tagout

In addition:

The locks should be durable and able to withstand the environment in which they are being used They should be substantial enough to prevent their removal without the use of excessive force The locks must be standardized in color, shape, or size in a company’s lockout/tagout policy Industry best practice is to use all red locks and devices, but some facilities may find it useful to use different colored locks for different departments

The employer must decide whether these locks are individually assigned or available from a pool of locks within their facility. It is also important to note that if an isolation point does not accept a lock, a lockout device with a lock must be used in this situation to keep the disconnect in the off position.

What is LOTO Step 5?

Lockout/Tagout Step 5: Stored Energy Check – Even after the energy source has been disconnected, in step 3 of the lockout safety process, and the machine has been locked out, in step 4, that doesn’t entirely guarantee that there’s no hazardous energy still stored within the machine or that it’s safe to perform maintenance.
