1 LOCK AND TAG PROGRAM FOR THE CONTROL OF HAZARDOUS ENERGY (Version August 99) INSTRUCTOR: Tom Tamshen Certified Safety Professional Risk Management Department

2 Lock & Tag2 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

3 Lock & Tag3 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.

4 Lock & Tag4 INTRODUCTION 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. What is NOT included?

5 Lock & Tag5 SCOPE (1) Covered: Locking out of all hazardous energy sources such as electrical, mechanical, hydraulic, pneumatic, chemical, or thermal.

6 Lock & Tag6 SCOPE (1) Not covered (1.2): Operation locks PPS locks to prevent operation Locks to block entry Locks for administrative control Construction Permanently disconnected

7 Lock & Tag7 APPLICABILITY OSHA: Required by OSHA as follows: (covers all Hazardous. Energy sources) (covers electrical only) This is for personnel safety and not an operational lock out.

8 Lock & Tag8 APPLICABILITY (2) Site-wide (all OTC) 50 V and above Below 50 V if hazardous Moving/rotating equipment Service and Maintenance (includes modifications, etc.) of any system involving hazardous energy.

9 Lock & Tag9 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)

10 Lock & Tag10 EXCEPTIONS (Cont’d) And only in following situations: Increases hazard (fire protection, life support, etc.), Or infeasible, Or testing which requires energizing.

11 Lock & Tag11 EXCEPTIONS (Cont’d) HOT TAP OPERATIONS (3.2): See manual.

12 Lock & Tag12 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.

13 Lock & Tag13 INTERLOCKS RESTRICTION ON INTERLOCKS (4): Interlocks not to be used in place of lock and tag on the energy source as per OSHA.

14 Lock & Tag14 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

15 Lock & Tag15 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.

16 Lock & Tag16 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.

17 Lock & Tag17 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.

18 Lock & Tag18 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)

19 Lock & Tag19 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).

20 Lock & Tag20 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.

21 Lock & Tag21 GLP (7) (Cont’d) STEP 5:Verification of isolation. Electrical: 1)Verify it cannot be started. 2)Check voltage, by a qualified person. Non-electrical: Verify machine is isolated and deenergized. STEP 6:Keep lock and tag on till finished. Every person must have his/her lock and tag
