Statistics Recent OSHA estimates indicate that each

year 120 deaths and 60,000 injuries occur as the result of unexpected activation of machinery, and nearly 75% of these accidents occur on jobs of 15 minutes or less.

Potential Mishap Outcomes

Electric shock and electrocutions Thermal burns Struck by objects Crushed by and caught between Loss of limb Mechanical Entanglement Engulfment Leading to property damage, injury, death

Direct Causes Lack of notification prior to re-energizing. Not verifying de-energized state. Failure to adequately bleed pressurized

system before disassembly. Unauthorized work Lack of communication between workers. Worker ignoring safety procedures.

Indirect Causes

Lack of Lockout/tagout/tryout program. Specific SOPs not developed or utilized. Workers not adequately trained or

supervised. Approved safety plan not implemented. Regular site safety inspections not

performed. Lack of safety equipment and/or use.

Fatal Incident

A 28 year old dump truck driver was crushed when pinned between the dump body and frame. The victim elevated the empty body and tried to lower it, but it had stuck in the elevated position. He left the cab leaned over the truck frame to look at the control valve. The dump body suddenly lowered pining him. He was found the next day by the company owner who was his father.

General

12.A.01 This Section shall apply to contractor-managed Hazardous Energy Control Programs (HECP) only, as well as all requirements of 1910.147, ANSI Z244.1, and ANSI A10.44. When a site is controlled by a contractor and USACE employees are affected by contractor-managed HECP (e.g., QA’s on construction sites, etc.), they shall comply with the contractor’s HECP.

Energy Sources Electricity Hydraulic Pneumatic Steam Thermal Chemical Gravity

Typical Equipment Requiring LOTO

Presses Saws Conveyors Pumps Production

equipment Trash

compactors Ovens

Isolation

Systems with energy isolating devices that are capable of being locked out shall be locked out.

12.A.04

Authorized Employee

Lockout and tagout shall be performed only by Authorized employees.

12.A.08

Training

Training shall be provided to ensure that the purpose and function of the HEC procedures are understood by employees and that employees possess the knowledge and skills required for the safe application, usage, and removal of HEC devices.

12.B.01

Training a. Each Authorized Employee shall receive

training in the recognition of hazardous energy sources, the type and magnitude of energy available in the workplace, and the methods and means for energy isolation and control.

b. Each Affected employee shall be instructed in the purpose and use of the HEC procedures.

c. All incidental personnel shall be informed of the procedures and prohibitions relating to restarting or reenergizing systems which are locked or tagged out.

12.B.01

Locks Blocks Chains Multi-lock hasps Wheel valve covers Ball valve covers

Types of Lockout Devices

Inspections Daily inspections shall be conducted to ensure that all requirements of the HEC procedures are being followed.

12.C.01

Periodic Inspections Periodic inspections

shall be documented and shall specify the system where the HEC procedures were inspected, the date of inspection, the names of employees performing and any deficiencies in complying with the HEC procedures.

12.C.02

Locks and Tags Locks and tags

shall: a. Be capable of

withstanding the environment that they are exposed to for the maximum period of time the exposure is expected, and

b. Indicate the

identity of the employee applying the device.

12.D.01

Locks

Locks shall, in addition to the requirements of section 12.D.01 be substantial enough to prevent removal without the use of excessive force or unusual techniques.

12.D.02

Tags Tags shall, in addition to

12.D.01 meet the following requirements: Have standardized print and

format Constructed and printed to

prevent UV light, wet locations, or corrosive environment will not deteriorate the tag

Attached in a reusable method Warn against hazardous

conditions

12.D.03

Application and Removal of Locks and Tags

The authorized employee shall affix locks and/or tags to each energy isolating device in accordance with the HEC procedures.

12.E.03

Personal Protective Grounds Following the application of locks or tags to energy isolating devices, all potentially hazardous stored or residual energy shall be relieved, disconnected, restrained, discharged, or otherwise rendered safe. 12.E.05

Verification by Authorized Individual

Before starting work on systems that have been locked/tagged out, the authorized individual shall verify that isolation and de-energization of the system have been successfully been accomplished.

12.E.07

Before locks or tags are removed and energy restored to the system, the authorized individual shall ensure that the following actions have been taken: a. The work area has been inspected and all

nonessential items (e.g., tools and materials) have been removed from the system, the system components are operationally intact, and all employees have been safely positioned or removed from the area; and

b. All affected individuals have been notified that the locks or tags are about to be removed.

Termination of Operation

12.E.09

Removal of Tags/Locks When the employee who installed the lock/tag is not available, the device may be removed by another individual appointed by, and under the direction of the Contractor Project Manager or Contractor designated authority.

Summary Lockout/tagout/tryout program must

be implemented. Specific SOPs must be developed and

utilized. Workers must be trained and/or

supervised. Approved safety plan AHA and ORM

must be implemented. Regular site safety inspections must be

conducted. Safety equipment must be used.
