4 4 Supervision of the Following BaBar Mechanical Technical Support Activities (Cont'd) Other basic hazards Agency workers not allowed to take SLAC SLAC management needs to direct the Legal Dept safety training to allow training of agency/contract people Radiation Practice ALARA principles Determine if task is "Non-routine" - write Non-routine JHAM Magnetic fields Attend GERT or RWT training Restrictive work areas - under end doors, etc. Avoid areas where magnetic fields are present Confined space/oxygen deficiency Eliminate presence of magnetic materials around Presence of flammable gases magnetic fields Noise - pumps, impact wrenches Take Permit Required Confined Space training Compressed air Limit time in restrictive work areas Earthquake Presence of eternal attendant when working in Fire restrictive work areas Inadequate lighting Wear ear protection when using impact wrenches Improper lifting of heavy objects Know evacuation procedures Aggressive project schedules Use additional lighting when necessary Distractions from casual observers Lift objects with legs - not back Varmints - skunks, snakes, black widows, etc. Minimize number of casual observers High vacuum equipment Do not allow aggressive work schedules to override Repetitive movements safety Lead & lead batteries Perform daily safety briefings Miscellaneous sovents, paint & lubricants Continuous safety oversight when practical Daisy chain of extension chords Take lead workers training Presence of electrical equipment Minimize repetitive movements Very large, very slow moving objects - end doors & backward end plug Store chemicals in chemical storage cabinet Label all chemical storage containers Limit chemical exposure to skin Do not daisy chain extension chords Minimize exposure to electrical equipment: Lock and tag Administrative controls

5 5 Bridge Crane and Hoisting & Rigging Work Operator shall determine if lift is "Routine" or "Non- Routine". A "Routine" lift is equivalent to an "Ordinary" lift as defined by DOE-STD A "Non- Routine" lift is a "Critical" lift or an "Ordinary" lift that has complexity beyond the operator's level of comfort. This judgment is based on the complexity of the lift and the skill and experience level of the operator. Pinching, crushing and amputation - severe injury or death Area Manager shall provide a list of qualified crane operators for tha area If lift is "Non-Routine", write non-routine JHAM (Lift Plan) and determine if Riggers should perform lift. This is a judgment call based on operator experience, complexity of the lift, and knowledge of the load and rigging equipment. If lift is performed by a casual operator, then either a "Non-Routine" JHAM (Lift Plan) is required or the lift must be performed in the presence of a qualified operator. Unexpected load movement Maintain current crane operator training Read Area Hazard Analysis and inspect lift area for potential hazards such as radiation, magnetic fields, oxygen deficiency, clutter, workers, etc. Potential back and muscle sprain from lifting heavy rigging components Attend periodic refresher rigging training Retrieve crane control box Lift located in proximity of hazards - radiation, magnetic fields, electrical equipment, pressure vessels, oxygen deficiency, etc. Maintain control of crane box Fill out crane pre-operations checklist Workers in lift area Crane operator has final say on lifts Inspect load for possible structural defects Uneven work surfaces, potential trip or fall areas Request safety oversight on complex lifts Select appropriate rigging accessories such as slings and shackles that are rated for the load for the given sling angle Equipment failure Remove people from lift area Inspect rigging accessories for defects & remove from service if necessary - replace rejected accessories Ensure that rigging accessories have current H&R Committee inspection sticker Inspect manual chain hoists and manual lever hoists for defects and remove from service if necessary - also notify H&R Committee about rejected components. Replace rejected manual chain hoists and manual lever hoists Operator error Rigging error Where appropriate use swivel hoist rings instead of eye bolts or eye nuts Wear PPE - safety shoes, gloves, hardhat and fall protection as appropriate Crane operator shall attend any lifted load

6 6 Bridge Crane and Hoisting & Rigging Work (Cont'd) Ensure that manual chain hoists and manual lever hoists have current H&R Committee inspection sticker Direct technical support staff to assemble rigging When using wire rope slings & grommets, check pin diameter/wire rope diameter ratio - substitute rigging components if necessary When using synthetic slings, install pads between slings and sharp edges Ensure that shackles are not rotated and that shackle pins are oriented towards the load When using a Below-the-Hook lifting device, ensure that the device displays a current H&R Committee inspection sticker Talk to load custodian if there are questions about the structural integrity of the load Use shackles with appropriate pin diameters for use with wire rope slings and grommets Include a load cell in the rigging setup if the hook load is uncertain or if a specific hook load is required. Inspect the load cell for damage and ensure that the load cell displays a current H&R Committee inspection sticker. Check rigging setup before lifting. Make sure slings are not twisted or knotted Move all personnel away from lift and path of load movement Check to make certain that there is no external connection to the load that could hinder the lift Slowly lift hook to tension slings. Manually check sling tension for uniformity. Readjust sling length if necessary. Reposition trolley and/or bridge if necessary. When using slings in a "choke" mode, slowly raise load to asess load balance. Lower load and reposition slings if necessary Slowly perform lift. Lower load and modify rigging setup if necessary. Slowly move lift to appropriate location. Ring bell to anounce bridge or trolley movement.

7 7 Bridge Crane and Hoisting & Rigging Work (Cont'd) Prevent rotation or swinging of load. Tag lines may be necessary. At the desired location, slowly lower load until slings are slack Disconnect rigging from load. Slowly lower hook and remove all rigging hardware. Move hook and rigging to a more accessible location if necessary. Inspect all rigging hardware for defects and remove from service if necessary Raise hook up to trolley and position trolley and bridge in appropriate location Secure crane control box in appropriate location Acknowledgements Print Name Signature Supervisor: Bill Wisniewski Participant:
