Work Interruption

All injuries involve some amount of work stoppage or interruption. When the injury occurs at work, stoppage takes place. The more serious the injury, the greater the work stoppage. 

As an example, a warehouse employee slips and falls on hydraulic fiuid that has dripped onto the floor. The worker slowly gets to his feet, wipes the hydraulic fiuid off of his pants, and walks to the first aid station for evaluation. He was slightly injured but did not require more medical attention. 

In a similar situation a supervisor slips and falls on a hydraulic spill. In this case the supervisor fractures his wrist and requires extensive medical care. 

Both of these examples represent an injury to the employees. In the first example a minimum amount of time was lost by the employee seeking medical care. In the second example the result was a very serious injury with significant lost time. 

If an organization were to analyze the many thousands of minor incidents and injuries, the realization of significant dollar losses would be evident. Some of the key points to consider regarding work interruption

The motivation for conducting toxicological tests for pharmaceutical, chemical intermediates and impurities arises from the need to ensure the health of employees by preventing adverse reactions from occupational exposure. Employers thus secondarily minimize the associated potential for work interruption. Programs in place at many larger companies routinely test new drug candidates and/or isolated synthetic intermediates for the purpose of occupational health hazard evaluation. 

I think that one of the driving forces for low- and medium-Btu gases by industry, is that they don t want their work interrupted by a stoppage of natural gas supply. They would like to... 

In 1946, The M. W. Kellogg Company was determined not to permit a Stanolind-Texas Company-Hydrocarbon Research consortium to race ahead with a fluid-bed hydrocarbon synthesis development, unopposed. Mr. Kellogg, in a rare decision for the head of an architect-engineering enterprise, decided to spend some of his company s own money to forge onward with the work interrupted on June 28. 

The use of different laboratories can give rise to results that are not comparable. Van Schothorst et al. [31] showed that despite the use of a carefully described standard method for the isolation of Salmonella from minced meat, the results from all laboratories were not the same. Differences between laboratories became especially apparent when samples were used with an even distribution of low numbers of Salmonella and high numbers of competitive flora. In this latter case four laboratories examined 100 artificially contaminated samples. The total number of samples found to be positive for Salmonella varied from 43 to 93. The differences were attributed to laboratory-associated factors such as differences in incubators, media preparation, time available to carry out the work, interruptions etc. When the analysis was carried out by the same workers, but in a single laboratory (repeatability), there were small (not significant) differences in the results. These differences were much smaller than when the analyses were carried out in different laboratories (reproducibility). The small differences were ascribed to the so-called human factor, that is interest, skill, dexterity etc. 

Bottomhole gravel filters and metal frlters with dense screens were at first employed in an attempt to stop sand entry into the well and avoid work interruptions. This problem was frnally solved by cementing these sands through coking, a method that was first tried in 1972. 

The joints attributed to the interruption of works are not in fact a different kind of joints. They are necessarily created as a result of work interruption. Under normal working conditions, work should stop at a pre-determined joint (contraction or expansion) so that an additional unnecessary joint is not created. However, in case of sudden and unscheduled work interruptions (mechanical failure, etc.), the vertical concrete surface is formed to a trapezoidal shape and tie bars 1 m long and 12 mm in diameter are placed at a spacing of 600 mm. 

One common effect of an accident is that it interrupts work. Effective investigations prevent repeated accidents and control work interruptions and inefficiencies. 

The supervisor should avoid work interruptions unless absolutely necessary. It is better to save all minor corrections until the observation is complete. However, if the employee does something in an unsafe manner, stop him or her immediately. The supervisor should explain what has been done wrong and why it is nnsafe. Call the employee s attention to the JSA/JHA when training was originally conducted within the framework of a JSA/JHA program. Check to see if the employee fully understands the explanation. This can often be done by having the employee tell and show the safe way to do the job. 

If excavation work interrupts the natural drainage of surface water (such as streams), diversion ditches, dikes, or other suitable means shall be used to prevent surface water from entering the excavation and to provide adequate drainage of the area adjacent to the excavation. Excavations subject to runoff from heavy rains wiii require an inspection by a competent person and compiiance with paragraphs (h)(1) and (h)(2) of this section. 

In 1886 Ferdinand Frederic Henri Moissan, a student of Fremy, succeeded where his mentor had failed. (Moissan also had his work interrupted a number of times while he recovered from HF and F2 poisoning.) He finally isolated this furiously reactive element by electrolyzing a mixture of anhydrous hydrofluoric acid and potassium fluoride with platinum-iridium electrodes in a platinum vessel. He chilled the apparatus to reduce the activity of the resulting pale-yellow gas. Equation (18.4) summarizes his procedure, which was the only method of preparing fluorine for a century and remains the principal method even today ... 

A phase of normal work, interrupted only by slight disturbances and rare cases of more serious hazards, which were recognized sufficiently early and parried (thwarted), thanks to a properly functioning security system... 

One common effect of an accident is that it interrupts work. Effective investigations prevent repeated accidents and control work interruptions and inefficiencies. The cost of delays, injuries, property damage, and insurance all add into the cost of the job. Control of costs is one way of judging a supervisor s job performance.
