  2. OUTLINE • Training file on CD Rom • Introduction • Video • L&T Program: • General (1-4) • Procedures ELP, GLP (5-7) • Additional requirements and hardware (8-9) • Training & inspection (10, 11) • Caution tags (12) • Documentation (13-15) • Most Frequently asked questions • Quiz Lock & Tag

  3. INTRODUCTION • What is Lock and Tag Program? • Program consists of: • Basic rules • General Lock and Tag Procedure (GLP) • Guide for making Equipment Specific Lock and Tag Procedure. • Training and Inspection Requirements. • Caution Tags. Lock & Tag

  4. INTRODUCTION What is NOT included? The program does not include Equipment Specific L&T Procedures. The departments have to prepare them for their equipment and train the authorized employee. All L&T procedures must be submitted to Safety for review. Lock & Tag

  5. SCOPE (1) Covered: Locking out of all hazardous energy sources such as electrical, mechanical, hydraulic, pneumatic, chemical, or thermal. Lock & Tag

  6. SCOPE (1) Not covered (1.2): Operation locks • PPS locks to prevent operation • Locks to block entry • Locks for administrative control • Construction • Permanently disconnected Lock & Tag

  7. APPLICABILITY • OSHA: • Required by OSHA as follows: • - 1910.147 (covers all Hazardous. Energy sources) • - 1910.333 (covers electrical only) • This is for personnel safety and not an operational lock out. Lock & Tag

  9. EXCEPTIONS (3) • Energized Circuits (3.1): • 3.1 May work on energized circuits without lock and tag provided: • Safe work practices (OSHA Subpart S) • AND approval obtained • AND safety watch provided (Chapter 8) Lock & Tag

  10. EXCEPTIONS (Cont’d) • And only in following situations: • Increases hazard (fire protection, life support, etc.), • Or infeasible, • Or testing which requires energizing. Lock & Tag

  11. EXCEPTIONS (Cont’d) HOT TAP OPERATIONS (3.2): See manual. Lock & Tag

  12. EXCEPTIONS (Cont’d) CORD AND PLUG (3.4) If the plug is in exclusive control of the worker, no L&T required. Use plug hugger or lock-a-plug device, if not in sight or in arm’s reach. Lock & Tag

  13. INTERLOCKS RESTRICTION ON INTERLOCKS (4): Interlocks not to be used in place of lock and tag on the energy source as per OSHA. Lock & Tag

  14. ACRONYMS Refer to Appendix C. • CLL = Crew Lockout Leader • ELC = Equipment (specific) Lockout Coordinator • ELP = Equipment Lock and Tag Procedure • GLP = General Lock and Tag Procedure Lock & Tag

  15. LOCK & TAG PROCEDURES (5) Two types of equipment: 1) Equipment which needs ELP. ELP = Equipment (specific) Lock and Tag Procedure. Note: All equipment needs ELP unless meets exceptions (See 6.3) 2) Equipment which needs GLP. GLP = General Lock and Tag Procedure. If Equipment meets exceptions (see 6.3) ELP is not required. Use GLP. Lock & Tag

  16. ELP (6) Similar equipment may be covered by a single procedure. RESPONSIBILITY (6.1): Dept. or shop in control of the equipment is responsible for ELP. Lock & Tag

  17. ELP (6) • PREPARATION OF ELP: (6.2): • STEP 1: Make inventory • STEP 2: Fill out forms for each equip. • 1. Equip. identification • 2. Controls • 3. Energy Sources • 4. Shutdown & verify • 5. Release from L&T • 6. List Authorized & affected employees • 7. Title sheet, approval, etc. Lock & Tag

  18. ELP (Cont’d) Which equipment needs ELP? ALL except those which meet all 8 exceptions (6.3): 1. No stored energy 2. Single energy source, readily identified and isolated. 3. Lockout will completely deactivate machine. 4. Machine remains isolated. 5. A single lockout will do it. 6. In exclusive control of the worker. 7. No hazard for other personnel. 8. No accident in the past. (All above are as per OSHA) Lock & Tag

  19. GLP (7) Which equipment may be locked out by GLP? - Meets exceptions (6.3) - And does not have ELP. Responsibility: Dept. or Shop in control of equipment is responsible for checking the equipment for exceptions (7.1). Lock & Tag

  20. GLP (7) GLP STEPS FOR APPLICATION: Check - are you authorized for the equip? If yes, proceed. STEP 1: Prepare and notify. STEP 2: Shutdown: use normal procedure. STEP 3: Isolate from energy source. (note interlock is not a substitute for L&T) STEP 4: Apply lock and dated tag. Lock & Tag

  21. GLP (7) (Cont’d) STEP 5: Verification of isolation. Electrical: 1) Verify it cannot be started. 2) Check voltage, by a qualified person.
