Maintenance supervisor

Maintenance is not a glamorous procedure however, its importance is second to none. Maintenance procedures are always controversial, since the definition of upkeep varies with the individual interpretation of each maintenance supervisor. The latitude of maintenance ranges from strict planning and execution, inspection and overhaul, accompanied by complete reports and accounting of costs, to the operation of machinery until some failure occurs, and then making the necessary repairs.

Completed work plans and any signed-off work orders should be submitted by the supervisor to their respective maintenance supervisor no later than the day after the job is completed. The maintenance supervisor should examine these documents for completeness and accuracy. 

If the work as called for on the work order is not completed due to lack of insulation, clean-up, tie-ins only being made, etc., but the shutdown portion of the work has been completed, then the first copy of the work order should be retained by the supervisor. The supervisor should then return the work plan to his supervisor denoting the reason for not completing work, explanation of variance, etc. The planning office will prepare a list of incomplete work following the shutdown and forward this list and a copy of the work orders to the appropriate maintenance supervisor for follow-up. 

Each maintenance supervisor involved in the shutdown should attend and be ready to quickly report the progress of each job as planned and scheduled for that day. In addition, the add-on list should be quickly reviewed daily. The shutdown critical path schedule will be reviewed and updated to track the progress made to date. 

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. 

A maintenance supervisor decided to temporarily use instrument air as a source of breathing air. For the safety of the workers, he disconnected the automatic nitrogen backup system as a well-intended one-minute modification. ... 

After several years of operation, conditions warranted the replacement of a pump bowl. The plant warehouse did not stock spare ductile iron pump bowls and none were accessible. A resourceful maintenance supervisor realized that there were a few other large pumps within the plant and they located one. Unfortunately, they chose a cast iron pump bowl which is very desirable for certain sodium chloride (table salt) brine services, but it is totally unsuited for large volumes of highly flammable materials. 

The team generates reports for two management reports. Vibration inspectors generate and distribute detailed surveillance reports to the equipment owners and the area maintenance supervisor so that corrective action can be planned. The inspectors also provide a summary report for middle management.

Nomoutine work which is conducted in process areas needs to be controlled by the employer in a consistent manner. Hie hazards identified involving the wmk that is to be accomplished must be communicated to those doing the work, but also to those operating personnel whose work could affect the safety of the process. A work authorization notice or permit must have a procedure that describes the steps the maintenance supervisor, contractor representative, or other person needs to follow to obtain the necessary clearance to get the job started. The work authorization procedures need to reference and coordinate, as applicable, lockout/tagout procedures, line breaking procedures, confined space entry procedures, and hot work authorizations. This procedure also needs to provide clear steps to follow once the job is completed in order to provide closure far those that need to know the job is now completed and equipment can be returned to normal. 

The maintenance supervisor did not organize an effective inspection program. 

Maintenance supervisor—inspects area and ensures that it is ready for safety inspector, ensures that equipment, vessels, and piping are cleared, ensures that safety equipment is located near job site, reviews procedure with person performing the work, confirms PPE required, and signs permit.

When asked specifically about any changes to the bus brake systems, the maintenance supervisor stated that, in preparation for winter, antifreeze had recently been added to the brake systems the temperature on the day of the mishap was, in fact, well below freezing. This change, however, should have prevented rather than caused the problem. 

The maintenance supervisor was then asked to outline any other recent changes to the brake systems. After a long silence, he replied, That s it " A couple of weeks earlier, in response to suspected water contamination in some systems, a desiccant had been added to the brake systems to absorb any water. The desiccant had a higher affinity for antifreeze than for water, so that when the antifreeze was added, it was absorbed and the water released back into the system. The water then froze, causing the brake failures.

An electrical maintenance supervisor with 15 years of experience ordered his assistant to deenergize a machine they were about to service. Before the assistant could cut the power, the supervisor reached into the back of the unit, made contact with bare leads, and was electrocuted. The supervisor had been an outstanding employee with no record of accidents or related lost workdays, but he had violated several company safety policies while performing this task. An electrician with his years of experience should never have made the mistakes he made. The results of the accident investigation revealed the...
