Mechanical supervisor

Exposure studies by Lavy et al. ( 1) on forest applicators showed a 6-day mean excretion of 0.033 mg/kg body weight from single day exposures. A considerable range of 2,4,5-T was measured in the urine for different crew members, with a mixer excreting the highest level (0.096 mg/kg) and a flagman the lowest level (0.001 mg/kg) per exposure. In a subsequent 2,4-D study on forestry workers, T. L. Lavy, J. D. Walstad, R. R. Flynn, and J. D. Mattice (1980, unpub), found mean values of less than <0.02, 0.02, 0.006, 0.003, and 0.001 mg/kg body weight, respectively, for batchmen, pilots, mechanics, supervisors, and observers. 

Results from our study on helicopter-applied 2,4-0 conducted in the Pacific Northwest showed that pilots and batchmen received the highest absorbed dose followed by mechanics, supervisors, and observers. The observers were stationed 200 to 500 feet from the hel i port. 

Person performing the work—inspects the job site gathers information from process representative and mechanical supervisor about potential hazards, special procedures, or conditions and selects and dons appropriate safety equipment before beginning work. 

The hot work permit must be filled out and signed before a safety inspector is called to review it and the work area. When the system is ready, the mechanical supervisor and safety inspector will show up to inspect the area. Chemical concentrations and potential hazards are assessed. The need for a standby will be determined by the mechanical supervisor and the operator. If everything is in order, the safety inspector will sign and post the permit and the work can be started. The permit must be displayed at the work site until the hot work operation is complete. The hot work permit must indicate ... 

The above definition means you, your staff, your dispatchers, mechanics, supervisors, managers, etc., are all considered to be a motor carrier — meaning everyone in the organization is personally responsible for safety and compliance. 

The mechanical supervisor will ensure the availability of equipment and maintenance personnel. 

Further investigations showed that all permits issued asked for goggles to be worn, even for repairs to water lines in safe areas. The mechanics therefore frequently ignored this instruction and the supervisors and foremen tolerated this practice. 

All drivers are responsible for refueling their vehicles at the end of each shift. All other routine maintenance should be performed by maintenance-department personnel, who are also responsible for maintaining service records. If a driver believes a vehicle is in need of mechanical repair, the driver should fill out the pink repair requisition form and give it to the shift supervisor. The driver should also notify the shift supervisor verbally whether, in the driver s opinion, the vehicle must be repaired immediately or may be driven until the end of the shift. 

This group includes operators, mechanics, first line supervisors, auxiliary staff groups such as technicians and engineers, and middle-level management. They should be trained on how to differentiate an incident from a nonincident and what to do once an incident is identified. 

Mechanical devices are such an integral part of everyday life that there are many real-life sources you can investigate to gain more knowledge of their design and use. A construction site is a great place to visit for a day to learn more about hand tools, cranes, pumps, and other devices. Ask the construction supervisor if you can take a tour. 

A complete design includes consideration of all aspects of the equipment specification such that the item could be built and operated. These aspects include the mechanical design, materials selection, fabrication requirements, operational details, safety features, versatility (e.g. turn down), economic considerations, etc. The scope (i.e. depth) of the design should be clearly specified by the supervisor. 

When conducted as a three-tiered process (Tier 1—Technical Review, Tier 2—Peer or Supervisor Review, and Tier 3—QA Review), internal review is an effective error-detection mechanism. Each tier in the review process involves the evaluation of data quality based on the results of QC data and on the professional judgment of the reviewer. The application of technical standards and professional experience to data review is essential in ensuring that data of known quality are generated consistently. 

The 2,4-D study was similar to the 2,4,5-T study which included analyses of air, patches and total urine. In this study three helicopter crews were monitored during their routine forest spray operations in Washington and Oregon. An additional objective in this study was to compare exposure from the routine operation (Tj) with that received when workers wore protective clothing and followed added precautions designed to limit exposure (T2). The Ti and T2 operations were conducted with the same individuals in each crew with a 1-week interval between spray operations. Each crew included a pilot, a batchman, a mechanic, a supervisor, and two observers. The observers were located from 67 to 168 m away from the spray operator. Their role was to represent persons who might be in the area, but who were not directly associated with the spray operation. Protective... 

Adequate mechanisms for reporting manufacturing departures, such as batch records that invite operator and supervisor comments and explanations and adequate change control. 

Furthermore, the supervisor and his two students appeared to share similar views on the relations of the new quantum mechanics to chemistry. At the end of 1929 Fowler, who was one of the editors for Cambridge University Press, asked London whether he would be interested to write a book on the foundations of chemistry in quantum mechanics . [18] Dirac during the same year had, as we saw, expressed his view about chemistry, which would permanently mark the physicists culture. By 1931, Fowler was already expressing a subtler view of the whole problem. In a report... 

At this section of the plant in the past, chemical process operators (not maintenance mechanics) handled the tank-filling step in the hydrotest process. Operators would typically drape a fire hose into an oversize roof nozzle and fill the tank from the nearest hydrant. In this case, it was reported the two mechanics asked their maintenance supervisor if they could connect the hose to a flanged lower-valved nozzle on the tank. The supervisor remembers requesting the mechanics to roll a blind flange at the top for venting purposes if they used the lower nozzle for filling. There must have been a miscommunication. Obviously the mechanics failed to understand the dynamics of the filling operation when they chose to open only the two 1/2-inch top vents. 

It was late on a Friday afternoon when a maintenance crew consisting of a welder and a pipefitter was assigned to stop a bad steam leak on the bonnet gasket of a 3-inch (7.5 cm) steam valve. A supervisor instructed the mechanics to fabricate a clamp that could be tightened around the valve bonnet to silence the leak of 260 psig (1800 kPa gage) steam and condensate. [15]... 

The alert mechanic informed the operations supervisors of the failures. Operations shut down the furnace. Maintenance mechanics replaced the bolts with the properly-specified high-strength stud bolts prior to any serious releases. 

The procedure was to clear the transfer fine of the waxy material with compressed air supply just before the transfer fine was put in service. On the evening of the accident, an operator connected an air hose to a 90 psig (6 bar) supply to clear the entire 200 meters (600 ft.) of feed line. The operator then walked to the elevated tank to determine if air could be heard rushing out of the tank vent. He heard nothing. The operator spoke to two maintenance employees working near the end of the 20-m3 (700 ft3 or 5,300 gallon) tank and left the area to find his supervisor. Shortly after that, one end of the tank blew off, and the two maintenance mechanics plunged some 40 ft. (12 m) to their deaths. [7]... 

Each plant must persistently train and create awareness in their employees of potential dangers faced with even small changes that can be easily introduced into their plant. This message must be given not only to the engineers and supervisors, but also to the chemical process operators and mechanics. 

The mechanics and their supervisor were astonished because they did not know of any flammables within this area. Furthermore, the previous hot work testing on the system did not reveal any flammables. 

Sharing the incident details with hundreds of mechanics, chemical process operators, and supervisors within the chemical complex. This training included stressing the proper flammable gas detection strategy. [3]... 

Mechanics document SRV test results and observations on a checklist. This information includes initial test pressure, and the condition of seats, stems, guides, springs, and inlet and outlet piping upon arrival at the plant. The appropriate second-level supervisor receives these results and a copy is maintained in the central SRV records. [8]... 

A prooftest program cannot be left to someone s memory. It must follow a well-structured format to accomplish the essential steps, regardless of the myriad of other activities and distractions that tend to absorb all the supervisors and mechanics time.
