How diesels powered storm cleanup efforts - diesel-powered equipment used to rebuild North Carolina in the aftermath of Hurricane Fran

Light towers, tub grinders instrumental in recovery operations after Hurricane Fran; "the diesel's finest hour"

When a natural disaster such as a hurricane strikes, simple commodities such as electricity and lighting become critical requirements for search and rescue operations. Then once the immediate demands are met, the emphasis shifts to questions of cleanup, restoration and reclamation.

It is interesting that in all of these cases, the diesel engine has become a key factor. Indeed, times of crisis are often the diesel's finest hour, as everything from small portable gen-sets to air compressors to massive machines used for search, rescue, recovery and recycling are more often than not powered by diesel engines.

A good example is when Hurricane Fran ravaged the state of North Carolina in September of last year. The killer storm came ashore at night, taking out the utility power grids almost immediately. Literally thousands of diesel-powered machines were immediately pressed into emergency service, providing power and light where needed. Months later, more diesel-powered machines were still at work for cleanup and reclamation activities.

Since Fran did the majority of its destruction before dawn, the most pressing need was for illumination. Untold numbers of people were rescued by the light supplied from truck- and trailer-mounted portable light units. Property damage was reduced because temporary repairs were made to damaged or threatened structures by crews using the same type of lighting.

Later on, portable light systems played an integral role in the cleanup operations, which went on continuously for nearly four months.

The storm roared ashore at Topsail Beach, N.C. The eye of the storm crossed that area about the time the first winds were whipping upon Raleigh, 135 miles inland. By the time Fran moved into Virginia and Washington, D.C., the winds had subsided somewhat. But in the meantime, North Carolina had been buffeted to the tune of more than 28 lives and $4 billion.

In Wake County, rescue and recovery operations were underway before the storm winds stopped. Hundreds of thousands of downed trees, some hundreds of years old, took out all electricity. This was especially true in the city of Raleigh where damage exceeded $9.2 million.

In the period that followed, the U.S. Army Corps of Engineers was assigned the enormous task of coordinating recovery operations. In one storm-related irony, the Corps of Engineers' Robert Cagle, who was appointed area recovery engineer in charge of the Wake County area, lost part of his house and all his garage in Wilmington, N.C., to the storm's fury.

One of the Corps' first projects was to assemble private contractors and subcontractors to do the actual cleanup work. At the forefront was Phillips & Jordan, Inc., a large, nationally-known land-clearing company that had done similar work following Hurricane Andrew in South Florida. The company has also participated in other smaller hurricane restoration work.

Portable lighting was the first essential for nighttime waste collection and reduction. The Corps of Engineers' emergency procedures manual set forth the minimum amount of light required for safe working areas under various conditions, requiring a minimum of 3 ft. candles of illumination at any general outdoor work site. Extra lighting was required in office areas and where equipment maintenance and repairs were being made at night.

An immediate call went out to construction equipment rental companies in the Raleigh area to round up all available lighting units. The Hertz Rental Corp. and Resco Rents operations in Raleigh both responded. Resco supplied more than 40 Coleman light towers and 100 pieces of other equipment, machines ranging from skidsteer loaders to wheel loaders. The equipment came from 16 various Resco locations, some from as far away as Kentucky.

Hertz supplied 30 Ingersoll-Rand light towers to Phillips & Jordan in the Wake County area and provided 200 pieces of heavy equipment in the Raleigh area alone. Some of this equipment came in from as far away as Michigan and Texas just for the Hurricane Fran cleanup.

The majority of the light systems utilized were Ingersoll-Rand Model L6 and L8 portable light towers. The L6 units are powered by Kubota D905 BG diesel engines, which drive Leroy-Somer 6 kW generators powering four 1000 W metal halide (MH) lights. The L8 units are driven by Kubota D1 105BG diesels, which drive 8 kW Leroy-Somer generators supporting four 1500 W lights. The masts supporting the lights telescoped up to 30 ft. high.

Each of the Phillips & Jordan collection and reduction sites had between 5 and 12 self-contained light towers. "The Ingersoll-Rand portable light towers were lifesavers," said Randy Perkins of Ashbrift, Inc., a grinding subcontractor to Phillips and Jordan. "They turned night into day. We would have been hard pressed to do our night work safely without them."

Statistics indicate the effectiveness of the portable lighting systems. Phillips & Jordan and its subcontractors worked a total of 401,440 man-hours without a lost time accident. When the almost inevitable accident happened, it was because an operator fell off his seat on a tree loading machine on a city residential street - in daylight.
