into account all the circumstances surround ing the particular job Safety observations serve to 1 Check adequacy of past training 2 Promote on-the-spot correction 3 Provide opportunities to compliment 4 Develop cooperative safety attitudes 5 Help supervisors learn about workers, and to identify problem workers 6 Sometimes suggest better job methods The kinds of special-problem employees who warrant such observations are 1 Inexperienced men 2 Accident repeaters 3 Chronic unsafe workers 4 Physical or mental cases In fact, all employees, even experienced workers, should be checked once in a while One reason why safety observation has not been more fully utilized is that safetymen and supervisors seldom develop or improve their power ofobservation Another is that planned safety observation involves a little more effort than the incidental safety observation There are several factors necessary for ef fective safety observation The inspector must 1 Be selective An inspector might look over a department first for safety, second for improvement of operations, third for training needs, and so on 2 Know what to look for The more a supervisor or safetyman knows about a job and a worker's responsibilities, the better an observer he will be 3 Practice observing The oftener a per son looks with the conscious intenbon to observe, the more he will see at each fresh tnal Like all skills, observation improves with practice 4 Keep an OPEN mind One way to increase open-mindedness is not to judge facts in advance The inspector must not deny the fact, no matter what conclusion it may seem to lead to The inspector must keep his mind open, at least until he has all the facts 5 DO NOT BE SATISFIED WITH GENERAL IM PRESSIONS A clean shop, or a careful rou tine, may still contain hidden hazards 6 Guard against habit and familiarity Asking the questions What, Where, When, How, and (especially) Why will often help uncover the real meaning of the situation 7 Record observations systematically All notes should be dated, with space for comment on action taken and on results of the action The notebook can serve both as a reminder and as a record of progress 8 Prepare a checklist A systematic check for litter, obstructions, handling of flammables, condition of fire-fighting equipment, and so on, will uncover tangi ble problems that can be corrected (Mak ing a checklist was discussed earlier in this chapter) Here are a few pointers that might help 1 Be firm, but friendly 2 Explain what and why 3 Review the safe alternative 4 Make your contact private 5 Get his reasons for acting unsafely 6 Get agreement on future practice It is sometimes necessary to watch men at work, not casually m passing, but closely This can be embarrassing to the men under observation--and one of the reasons for hav ing a small inspection team When it is nec essary to observe a man closely, a member of the team should talk to him and explain what is going on, then ask his permission to watch him as he works Usually, the man will con tinue his work naturally after such an intro duction If, however, he is nervous or un cooperative, it is better to postpone the observation When a person is observed performing an unsafe practice or act, the supervisor is faced with a problem in human relation skills The worker should be left with the feeling that he has been corrected in a decent way Scheduling Inspections.

Proper classification will lead to better treatment even though the physician himself is not familiar with skin diving.

Crushing and excessive wear of wue rope are minimized by use of helically grooved drums with capacity for one layer of rope In any case, the number of layers should be limited to three Rope lifters are recom mended when two or more layers are wound on drums To distribute wear at crossover points uniformly, 1J* wraps can be cut off every six months or three or four tunes during the life of the rope In no case should there be fewer than three full wraps on a drum In general, wire rope bending--first in one direction and then m the opposite--over sheaves or drums wears out rope faster than any other known cause and should be avoided It is desirable that the fleet angle" not ex ceed 1 degree, 30 minutes, to reduce any tendency for the rope to open-wind Also, a minimum limit of 0 degree, 30 minutes, to assure the rope's starting back on the next layer, has been found desirable Adherence to these specifications will help ensuie uni form winding on smooth-faced drums and will The fleet angle is the included angle between the rope winding on the drum and a line perpen dicular to the drum shaft and running through the head or lead sheave
