*Energy Isolation LOTOTOIntroductionIt is the Group H&S policy to prevent the unintended or unexpected startup or release of hazardous energy during servicing, maintenance, or modification activities. No employee shall install, service, remove, or perform maintenance on any equipment or machinery that may involve an energy hazard, until that equipment has been de-energized, locked, tagged and verified to be in a zero energy state in accordance with this document.Since January 2006, Lafarge has experienced 17 fatal injuries related to working on machinery, equipment, or processes due to uncontrolled energy.

*Energy Isolation LOTOTOWhats Required ?Ensure the advisory is presented, clearly communicated, and discussed.Implement the one lock, one person, one energy source principle including the issuance of designated locks and tags.Review and align current practices with the mandatory LOTOTO sequence principle.

*Energy Isolation LOTOTOhazardous energy Any type of energy that, if released unexpectedly, can cause an injury or damage.It has two major forms: kinetic energy from movement (e.g. rotating shaft) and potential energy which is stored energy (e.g. tensed spring) that when released becomes kinetic energy.

*Energy Isolation LOTOTOZero Energy state Is the condition when machinery or equipment is completely isolated from all sources of hazardous energy and the presence of residual or stored energy has been dissipated or restrained. Residual or stored energy sources must be controlled and monitored to prevent re-accumulation.

*Energy Isolation LOTOTOKey Principles There are five key principles specific to the control of hazardous energy that all workers must understand including: Controlling Risk (Hierarchy of Controls)Lockout + Tagout + Tryout (LOTOTO)One Lock, One Worker, One Energy SourceMandatory LOTOTO SequenceTraining & Hazard Awareness

*Energy Isolation LOTOTOKey PrinciplesLOTOTOOnce the machinery or equipment has been correctly disconnected or isolated from its energy sources it must be locked out, tagged out and tried out.LO (Lockout) means to physically lock the machine or equipment controls (e.g. locking a valve handle on a pipe).TO (Tagout) means to attach an information tag with the lock to identify the owner of the lock and the date it was applied to the machine or equipment.TO (Tryout) means to verify by testing that the machine or equipment has been properly de-energized and will not operate before beginning a task on the machine or equipment.

*Energy Isolation LOTOTOAll Lafarge employees and contractors who perform tasks on machinery or equipment must be issued personal locks and tags. When performing LOTOTO on a simple machine with a limited number of energy sources, each worker must apply his own lock(s) to all energy source(s). Example 1: One worker must work on one machine that has three electrical disconnect switches. The worker must apply one personal lock and tag to each disconnect switch (i.e. three locks and three tags).Example 2: Three workers must work on one machine that has three electrical disconnect switches. Each worker must apply one personal lock and tag to each disconnect switch (i.e. nine locks and nine tags).Key PrinciplesOne Lock, One Worker, One Energy Source
