TRC DART

Other Significant Events• June 2, 2006 to June 16, 2006 – NL, subcontract technologist tech

experienced respiratory tract irritation. JLab staff denatured alcohol P-Card purchase from Home Depot. No MSDS. IH later determined that the denatured alcohol contained up to 60% methanol.

• June 24, 2006 – FEL outside, metal tent frame structure fell; no injuries

• July 10, 2006 5:00 PM – NL, Staff noticed wires hanging from a combination starter in the North LINAC. Further investigation revealed that the wires were connected to a breaker that was labeled spare and had a “SPARE” sticker on it and was turned off.

• July 28, 2006 Noon – NL, while removing extension cord, receptacle cover plate pulled out of the aluminum wire-way exposing live connections and causing seeing sparks

• Sept. 21, 2006 – Exterior, Test Lab - mobile equipment left unattended with the keys in it borrowed by untrained/unauthorized subcontractor.

Other Significant Events, cont’d.• Oct. 24, 2006 - 10:00 AM Test Lab, during a lift, a staff member

tipped multi-drawer roll around toolbox over backwards out of the slings, and it fell to the floor.

• Oct. 31, 2006 11:50 PM - ARC Bldg Telephone Room, smoke detector went into alarm, UPS failed

• March 2, 2007 15:40 – Test Lab, leaky scrubber o-ring dripped causing potential acid exposure to employee’s head

• April 3, 2007, 4:00 PM – Hall A, technicians receive what they believe was a low voltage shock while performing a beam cavity tuning procedure.

• April 6, 2007, Hall C - section of large diameter beam line stored without proper RadCon postings

• June 27, 2007, Bluecrab - activated Lambertson magnet coil found

L/L from Other Significant Events

• Common work planning issues

– Availability of materials

– Task planning (design of work sequence)

– Training and preparation based on hazards (procedures?)

• Common work conduct issues

– Interim status of work or equipment at the job-site

STOP 2006 Data• 177 Engineering recorded Observation Reports

– 4145 discrete observations– 165 (or 4%) representing unsafe or potentially

unsafe acts• Considerable effort given to the STOP process by

Engineering line managers and Ops Crew Chiefs• Ongoing effort by FM for STOP Observations of

subcontractors• Although most new effort was observations

conducted by Engineering, observations covered activities in most all lab organizational units.

Quick look at 2006 STOP Observations

STOP 2006 Summary

• Common to most all observations--Anyone can be observed; staff, users, subs, students-----Verbal positive feedback from observer is routine------ Positive response back to observer (less than 5 direct

negative responses) is routine---

• Net result seems to be: ---Raised safety consciousness and situational awareness------Consistent observed management safety commitment------Improved safety performance---

• New tools are being developed to enter and manage data. These will be available October 2007

Primary CATS Cause CodesLevel 0 & Tracking Only Removed

Since inception of cause codes in January 2007

CATS Data

Work Observations during the SAD• At some time (and probably several times) during the SAD

you will be approached by supervisors, line managers, coworkers, safety staff, or some combination thereof.

• They will want to observe your work from a safe perspective and then talk with you about your reasons for and your approach to working safely.

• They will also talk to you about things particular to your work like task hazard analyses or pre-job planning, any procedures in use, your PPE, any tools and equipment in use, etc.

• Please work with them. Observations usually take about 15 minutes. The observation is anonymous – only the observer name is recorded.

• If you have questions about a particular work observation or the work observations in general, just ask the observer!

Additional General Safety Items• Radioactive Material Movement: two recent events point to a need

for rigor in the control of radioactive material

• Lambertson coil at Bluecrab

• C50 - multiple activated components isolated during disassembly

• Contact RadCon, work out a process for managing radioactive components for your task, make sure every one in your workgroup follows that process!

• Critters (spiders, snakes, chiggers, mosquitoes). If you have a pest control problem, call 7400 and obtain support from FM pest control subcontractors!

• Summer students and visitors are on site! Traffic safety (parking lot etiquette) seems to suffer first. Please dialog with students and pass on the expectation to work deliberately and safely.

Final Notes• Summer is traditionally a “high injury” time

• Lots of distractions• New staff and new students, subcontracted work• Intense work schedule – 3 month SAD• Our first aid case rate says we’re not immune from injury!

• What is the antidote?

• Carefully planned activity; plans that reduces opportunities for injury by properly engineering a task or introducing controls.• Deliberate actions; follow procedure and accepted work practice; don’t work-around with out stopping, thinking, reevaluating!• Situational awareness; what’s my next possible injury and how can it be avoided? How am I impacting others working around me and vice versa?

QUESTIONS?

Proceduresa.k.a.

(Work Control Documents)

Why?Which Type?

Phil MuttonJuly 12, 2007

STOP Observations, Lessons Learned, and Other Feedback

• Common Findings (JLab and other labs)– Lack of procedures– Inadequate procedures– Incomplete procedures– Procedures not followed– Unclear lines of responsibility

Why Procedures?

Why Written Procedures?

• Consistently safe and high quality work every time.– Capture knowledge and use best practice

– Safety Precautions– Environmental Precautions– Methods– Specific Procedures

– Authority– Responsibility – Qualifications– Equipment

• Avoid ambiguity:

Which Type to Use?

• SOP – Standard Operating Procedure

• OSP – Operational Safety Procedure

• TOSP – Temporary Operational Safety Procedure

• Formal• Specified Approval

Process• ESH&Q Archiving

• Less Formal• Approved and

Controlled within Department

or• “Procedure”

Standard Operating Procedure• Standardize recurring processes• Use when hazards are common (well understood)

– ESH&Q Manual, referenced standards, and established methods provide mitigation guidance - typically to get to RC 0 or 1

Example:Electrical Safety SOP (a few pages)• Applies to all electrical work in the department. • Emphasizes Authorization, Qualifications, Classes and Modes of work,

PPE guidelines…

Procedure

• A step by step guide for a specific task.• Less formal than SOP, OSP, or TOSP• May contain only technical details• Includes other information (safety, environmental,

equipment, etc.) as appropriate

ExampleKlystron Replacement Procedure (19pp)Reset Box Power Supply Procedure (3pp)• Typically provides task and

equipment specific details that are not included in an SOP

Procedures

• Format defined by department to suit specific needs

• Managed and Approved within department

• A Safety Oriented Document for Special Situations• For Work Involving “Unusual” Hazards• Work may be repeated periodically• May require work to be performed under RC 2 conditions• Documents the people, equipment, methods, specific procedures,

hazard analysis, and safety requirements

Operational Safety Procedure

SOP and OSP (Chapter 3310)

Expiration = 3 years

Same Approvals

Temporary Operational Safety Procedure

• A Safety Oriented Document for Special Situations• Temporary work procedure for unique tasks• For Work Involving “Unusual” Hazards

• Documents the people, equipment, methods, specific procedures, hazard analysis, and safety requirements

TOSP (Chapter 3320)

Expiration = 3 months max.

Slightly DifferentApprovals

Communication

• Provide a user sign-off sheet– Participants acknowledge having read and

understood the procedure– An agreement to work in accordance with the

procedure

• Use the document while working– Discuss it in the pre-job briefing– Post in the work area, or carry in toolkit...– Use it as a checklist

Safe, High Quality Work

• Without procedures, you may miss the boat!

• Don’t take a chance

– Write it all down, and then use the document

QUESTIONS?

Electrical Safety BriefingBill Merz

Topics• Worker Qualifications

• Circuit Breaker Operations

• NFPA 70E Assessment Findings

Safety Requirements for Workers• Qualified Electrical Workers

– Knowledge– Generalized Training

• General Electrical Safety– Hazards Identification and Policy– Modes and Class– Work Practices, PPE

• NFPA -70E Training (Arc Flash Hazards, Boundaries)

• CPR-AED• Lock Tag and Try

– Equipment Specific Training• For the task being performed

– Authorization• Supervisor

• “Unqualified” Workers– Basic Recognition and Avoidance of Hazards

• Working in the vicinity of electrical hazards• Familiarity with electrical safe work

practices– Potential for Injury

• Due to electrical shock– Training and Knowledge

• Commensurate with task

Safety Requirements for Workers

Circuit Breaker Operationa clarification of rules

• These rules apply if all covers are closed• The two pertinent hazard categories

– Category 0• Applies to all Accelerator 480/208/120 VAC

Circuit breakers, safety switches, Motor Control Centers

• De facto default category• Exceptions to the above rule:

– >25 kAmp fault current, 30 msec fault clearing times

– Labels indicate a higher category– Breakers on unit substations (outdoor

hardware)– Category -1

• Allows the reduction to a lower level if:– Available fault Current is <10 kAmps

• Category 0– Use this category PPE on all 480 VAC service

circuit breakers or switches (except as noted on previous slide)

• Safety glasses• Long pants – Non-melting or natural fiber

clothing– cotton, wool, silk, rayon, or blends,

4.5.oz/yd2

• Long sleeve shirt – Non-melting or natural fiber clothing

– cotton, wool, silk, rayon, or blends, 4.5.oz/yd2

• Undergarments – non melting…..• Note: Gloves not required by NFPA 70E

Circuit Breaker OperationRequired PPE

Breakers and Switches 32• Examples of 480VAC

Switches

• Category -1– Use this on all 208/120 VAC inside the fence

• Safety glasses• Long pants – Non-melting or natural fiber

clothing– cotton, wool, silk, rayon, or blends ,

4.5.oz/yd2

• Short sleeve shirt, T-shirt – Non-melting or natural fiber clothing

– cotton, wool, silk, rayon, or blends, 4.5.oz/yd2

• Undergarments – non melting…..• Note: Gloves not required by NFPA 70E

– Only exception I can verify for whole lab site is in VARC, but there may be others outside the fence or in the end stations

Circuit Breaker OperationRequired PPE

Breakers and Switches• Examples of 208/120 VAC

DoE NFPA 70 E Assessment Results• Electrical Gloves

– Gloves must be tested• They should have a date stamp on them• They must be re-tested or discarded after 6 months from last test,

whether used or not.• They must be retested after each use (air test)• Must be retested electrically after each use if leather outer gloves

not used• Recommendation – use leather outer gloves whenever using

electrical gloves

• FR Clothing– FR rated clothing is required for Hazard Category 1 and

Up• In accordance with NFPA 70E – 130.7(C)(12)(c) “Underlayers”.

Meltable fibers such as acetate, nylon, polyester, polypropyleneand spandex shall not be permitted in fabric underlayers (underwear) next to skin

• Any employee performing work requiring FR clothing MUST wear the appropriate natural fiber underneath

DoE NFPA 70 E Assessment Results• Meters

– Verify that electrical test meters are rated for the application.

• Newer meters are categorized as CAT 1, 2, 3, or 4.• Typically a category 3 or 4 is appropriate to verify

zero energy for lock, tag, and try (LTT) applications.• The category is usually listed on the front of the

meter near the connections for the test leads but may be posted somewhere else on the meter.

– This does not mean you need to get rid of your present meter if not a CAT 3 or 4

• You may be able use it on applications that do not require this rating

• This rating is not the same as a voltage rating

Meters – from Fluke web sitehttp://us.fluke.com/usen/support/appnotes/

Summary

If it doesn’t seem right, even if you are trained,and your supervisor asked,

don’t do it…talk about it first!
