ANSI ASSP Z244.1 pdf free download.The Control of Hazardous Energy Lockout, Tagout and Alternative Methods.
3.13 Group Lockout
A procedure that provides equal protection for multiple users working on the same de-energized system.
3.14 Guard
A physical barrier that prevents or restricts access to areas of the machine, equipment or process where a hazard exists.
3.15 Hazardous Energy
Any electrical, mechanical, hydraulic, pneumatic, chemical, nuclear, thermal, gravity or other energy that could cause harm to personnel.
3.16 Interlock
A device or system whereby the status of one control or mechanism allows or prevents the operation of another.
3.17 Lockout Device
A positive means, such as a lock, for individual control that secures an energy-isolating device in a position that prevents the energizing of a machine, equipment or process. This includes devices such as accessories to go over valves and other isolation devices.
3.18 Lockout
The placing of a lock and tag or an identifiable lock on the energy-isolating device.
3.19 Lockbox
A container typically used in group lockout that secures all keys to locks on secured energy-
isolating devices and allows all exposed persons in the group to apply their personal lock.
3.20 Multiple Energy Sources
More than one source of energy going into a machine, equipment or process.
NOTE: This could be two electrical energy sources, electrical and pneumatic, electrical and hydraulic or any similar combination of energy sources.
3.21 Normal Operations
The use of a machine, equipment or process to perform its intended function.
3.22 Permit System
A process that provides a systematic risk assessment; the precautions required before the work
proceeds; information for the users; and the documentation and management signoff of the risk.
3.23 Risk Assessment
An evaluation of the probability and the degree of the possible harm or damage to health due to a hazardous situation in order to determine the risk reduction measures. See Annex A.
3.24 Risk Assessment, Task-Based
A risk assessment approach that identifies the tasks to be performed and the hazards
associated with elements of the tasks.
4. Responsibilities
4.1 Suppliers
Within the scope of their work activity, suppliers shall be responsible for designing, building, integrating and installing machines, equipment or processes that comply with clause 5 so that the user can effectively control hazardous energy during activities outlined in clause 1 .1.
4.2 Users
Users shall be responsible for complying with the applicable provisions of this standard by establishing an effective program for the protection of persons from hazardous energy during activities listed in clause 1 .1.
NOTE: A user can become a supplier if the user performs work within the definition of such an entity (see Definitions).
Users shall determine which method(s) is most appropriate for controlling hazardous energy in their operational environment: lockout, tagout, alternative methods or a combination of these.
The user shall obtain machines, equipment and processes that comply with clause 5.
The user shall be responsible for the upgrade of non-compliant equipment to be compliant with clause 5.
If the user obtains components, parts of machines or assembles a number of machines into an integrated manufacturing system, the user assumes the role of supplier and must fulfill the requirements of clause 5. The user shall obtain equipment with energy isolation devices that allow authorized persons to execute the hazardous energy control program outlined in clause 6.
NOTE: A single energy-isolating device that supplies multiple operations or machines, while satisfying requirements, can create situations that encourage personnel to deviate from fulfilling the intent of this standard. Additional local isolation devices or the implementation of alternative methods could be necessary to eliminate these situations.ANSI ASSP Z244.1 pdf download.
