While we attempt to thoroughly address specific topics, it is not possible to include discussion of everything necessary to ensure a healthy and safe working environment in a presentation of this nature. Thus, this information must be understood as a tool for addressing workplace hazards, rather than an exhaustive statement of an employer’s legal obligations, which are defined by statute, regulations, and standards. Likewise, to the extent that this information references practices or procedures that may enhance health or safety, but which are not required by a statute, regulation, or standard, it cannot, and does not, create additional legal obligations. Finally, over time, OSHA may modify rules and interpretations in light of new technology, information, or circumstances; to keep apprised of such developments, or to review information on a wide range of occupational safety and health topics, you can visit OSHA’s website at www.osha.gov

Scope

Covers servicing and maintenance of machines when UNEXPECTED start-up or release of stored energy could cause injury.

What Does Lockout Mean?

• Complete Deenergization of a piece of equipment or machine through the use of mechanical energy isolating devices.

– Please NOTE that control circuits (CNC’s, PLC’s, motor starters, emergency stops) ARE NOT Energy

Isolating Devices.

When Does Lockout Apply?

• During servicing and/or maintenance of machines and equipment.

• During normal production operations IF:

– A Guard or Other Safety Device is Bypassed or

Removed

OR

– A Body Part is Placed or Has the Potential to be

Placed in a Point of Operation or Other Danger

Zone

Does Not Cover

• Construction, agriculture, maritime

• Installations under exclusive control of electric utilities for power generation, transmission and distribution (1910.269(d))

• Oil and gas drilling and servicing

• Exposure to electrical hazards from work on, near, or with conductors or equipment in electric utilization installations (1910.333)

Also Excluded

• Normal production operations (Subpart O –

Machine Guarding applies - 1910.212-219)

• Work on cord and plug connected equipment where plug is under exclusive control of the employee performing the servicing and/or maintenance

• Hot tap operations, under special conditions

Application - Minor Servicing

• Note: “Minor Servicing Activities Exception:

Minor tool changes and adjustments, and other minor servicing activities, which take place during normal production operations, are not covered by 1910.147 if they are routine, repetitive, and integral to the use of the equipment for production, provided that the work is performed using alternative measures which provide effective protection (See Subpart O of OSHA’s

General Industry Standards).

Minor Servicing – Alternative Measures

• Shutting down the machine is not an alternative means of protection and does not protect the operator or other employees from normal production operation hazards because the machine or equipment can be easily turned on.

• Alternative means may include: interlocked barrier guards, presence sensing devices, special tools, techniques or other safeguards which are under the exclusive control of the employee.

Purpose of the standard

• Requires employers to:

♦ establish a program, use procedures and provide training for affixing lockout or tagout devices to energy isolating devices and to otherwise disable machines or equipment to prevent unexpected energization.

Definitions

• Servicing and/or maintenance – constructing, installing, setting-up, adjusting, inspecting, modifying, and maintaining and/or servicing machines or equipment. These activities include lubrication, cleaning or unjamming, making adjustments and tool changes, where employees may be exposed to unexpected energization, start-up, or release of hazardous energy.

Energy Control Program

• The employer shall establish a program consisting of

♦ an energy control procedure,

♦ employee training, and

♦ periodic inspections to ensure that, before any employee performs servicing or maintenance on machines or equipment where the unexpected energizing, start up or release of stored energy could cause injury, the machine or equipment shall be isolated from the energy source, and rendered inoperative.

Lockout vs.Tagout

• If an energy isolating device is not capable of being locked out, a tagout system shall be used.

• If an energy isolating device is capable of being locked out, lockout shall be used unless the employer can show that a tagout system provides full employee protection

(Tags Plus).

New or Modified Equipment

• After January 2, 1990, whenever replacement or major repair, renovation or modification of a machine or equipment is performed, and whenever new machines or equipment are installed, energy isolating devices for such, shall be designed to accept a lockout device.

Materials/Hardware

• Provided by employer

• Singularly identified

• Only devices used

• Not used for other purposes

• Durable

• Standardized

• Substantial

Energy Control Procedure

• Procedures shall be developed, documented and utilized for the control of potentially hazardous energy when employees are engaged in servicing and maintenance.

Common Pitfalls

• Failure of all exposed employees to install a lock.

• Failure to anticipate re-accumulation of energy.

• Failure to establish the specific tasks that require

LOTO.

• Failure to Lockout due to perceived feasibility issues, time constraints, … etc.

• Failure to distinguish between LOTO tasks and Minor

Servicing tasks. Failure to understand the difference.

• Failure to use an acceptable energy isolating device.

Where do we find these problems?

• Maintenance Tasks

– Relatively high rate of compliance

– Working hot is sometimes an issue due to perceived feasibility issues

• Production Tasks

– Low rate of compliance

– Machine set-up, clearing jams, tool changes, new technology
