1.                  Jib crane

E.                  TRIP

1.                  cables run across walkway

2.                  Cooling hoses, dipole stand, multipole stand

3.                  Slip hazard from standing water per water lines

4.                  Trip from wood supports sticking out from magnets

F.                  CHEMICAL

1.                  Absorption through skin

2.                  Carrying hazards home via clothing

3.                  Eyes; splash hazards

4.                  Fumes from welding




1.                  High amperage power supplies and test equipment are roped off and marked with signs and an amber beacon. All personnel working in this area are briefed on the hazards and how we protect against them.  Anyone entering area while tests is in progress is informed of the hazards.

2.                  Extension cords and power tools are taken out of service if a problem is spotted.  All of our power tools are tested and inspected quarterly for good ground and insulation

3.                  Hy-pot tester is used to find possible bad spots in insulation.  Tester is equipped with a momentary switch so that it cannot be energized if left unattended.  We use signs and you have to be taught how to use the tester and signed off on it by Al Guerra before you can use it.

B.                 MATERIALS HANDLING

1.                  The straps that we use the most are kept in our area and are inspected weekly.  We use the strongest straps we can get to fit the job, and we make sure straps and slings are protected against sharp corners and edges while in use and in storage.

2.                  We do not place ourselves in a position where a body or body part can be caught between a suspended load and another object.

3.                  If a load is close to the max rating of the equipment used, the CEBAF crane operator will be notified of he concern.

4.                  We make sure that no loose parts, bolts, tools, etc., are on the object being moved that could fall while overhead.

C.                 FIRE

1.                  Solder station is not used near combustibles, and iron is kept in its thermal protective holder.

2.                  Silver soldering and other jobs that are done with a torch requires a hot work permit issued with to the person doing the work.

3.                  Flammable liquids are keep in flammable cabinet except when in immediate use.

D.                 PINCH/CRUSH

1.                  Our jib crane is very close to shelving units.  This section is roped off with signs stating “No Entry.”  Any person(s) reporting to work in the area are briefed on this hazard.  Anyone in the area while the crane is in use is told about the hazard.

E.                  TRIP

1.                  Cables running across main walkway are covered with heavy duty cable protector and are painted bright red.  Cables running across restricted walkways are protected by the walkway being roped.

2.                  Because of the number of magnets on water at one time, there are numerous hoses in two locations.  The hoses are kept rolled up off the floor when possible.  When hoses are stretched out to magnets and present a problem, the area is roped off to prevent traffic over hoses.

3.                  Because of the hundreds of connections made on magnets in this area, water on the floor is guaranteed.  At the end of each task we use rags to clean up spills and leaks.  When breaking a connection, we use drip pans and buckets to minimize the spill or leak.

4.                  Our magnets are stacked in every available spot and are stacked on wood (mostly on 2 x 4s).  We use exact length when possible, also making sure that no wood extends into a passage way.

F.                  CHEMICAL

1.                  Absorption through skin is prevented by using proper protective equipment; gloves, face shield, etc.

2.                  We prevent the spread of a hazard by using chemicals in moderation and used carefully so the chance of splashing or spilling is reduced.  Also, with the proper use of protective equipment and knowing the chemical involved by reading the MSDS before usage, if not familiar, keeps the risk to a minimum.

3.                  We protect our eyes by using goggles, face shields, and well ventilated areas to protect against fumes.

4.                  Some welding and silver soldering is done in this area.  We make sure we know what kind of metal is being heated.  We make sure metals are free of chemicals, cleaners, paint, etc., which may burn and or emit fumes when heated.  We make sure we have good ventilation



1.                  If a job or procedure seems unsafe, it may be stopped immediately.  Then, the appropriate supervisor, safety warden, and safety officer are notified.

2.                  If the hazards can be lessened by signs and/or barriers, they will be put into place.

3.                  If the hazard requires a procedure change, the proper supervisor or originator of the initial procedure is to be notified and changes are to be made.

4.                  If training or a lack of training is the problem, then seek individual or group training on the procedure or equipment.  If the procedure or equipment is not repetitive or training is not practical, then we find someone who is qualified to do it for us.
