In industrial environments, itâs usually essential to run short-term utility strains, whether or not theyâre electrical and communication cables, water hoses, or course of hoses containing oil or chemical compounds. This whitepaper critiques conventional strategies of defending these strains from car site visitors. Limitations of every strategy are mentioned.
Historically, safety of utility strains from car site visitors has been slightly primitive. On concrete slabs, two scaffold boards can be run facet by facet, the strains laid between them, and a 3rd scaffold board nailed on prime to provide a crossing ramp. In soil, trenches have usually been dug and the strains buried. In both case, energy or communication strains can also be strung overhead.
Utilizing scaffold boards to guard strains, which has been the prevalent observe in websites similar to chemical vegetation, is fraught with issues. First, theyâre costly to construct. The boards are heavy, so it takes two males and generally a supervisor, relying on work guidelines. The scaffold boards are nailed collectively, however as soon as in service, the boards splinter and the nails again out, inflicting flat tires on the crossing automobiles. Boards have to get replaced, and generally the very utility strains that the boards are designed to exchange grow to be broken. On the finish of the job, the crossing must be dismantled, and the boards thrown away⊠theyâre now not appropriate for scaffolding. A significant refinery estimated the price of constructing, sustaining, and deconstructing a typical scaffold board crossing at greater than $1500 for a typical 90-day upkeep âturnaroundâ, not counting the fee and aggravation of flat tires. And a minimum of one incident occurred the place a nail was pushed right into a excessive voltage line by a heavy observe car, inflicting an emergency shutdown of the method unit and creating an imminent hazard for the observe car operator.
In work websites similar to oil rigs, trenching has been a dominant technique of defending strains. Many oil and gasoline wells as we speak lay a soil cement barrier to stop any spilled materials from absorbing into the earth and contaminating the location. To trench, nevertheless, a crew known as in and deliberately breaches that barrier. A trench is dug, PVC pipe is run, and the utility strains threaded by way of the pipe. On the finish of the job (usually solely 45 days or so on gasoline wells earlier than it strikes to the subsequent website), the strains must be dug up and retrieved.
Stringing strains overhead is usually finished, however can also be expensive and presents a restrict to the peak of site visitors that may move beneath.
As an progressive various, many industrial websites have determined to make use of merchandise which might be explicitly constructed to quickly shield hoses and cables. These âtemporary road crossingsâ are constructed out of metal to endure the rugged surroundings current in chemical vegetation, refineries, shipyards, and oil rigs. They solely require one man and a forklift to put in, are modular in design, and can be found for rental or sale. Rental âboardsâ present the benefit of being low price, solely being on website when theyâre wanted, and are funded out of an working funds. Most customers discover the price of utilizing these metal âboardsâ or ârampsâ is 40% decrease than utilizing scaffold boards, and 10% decrease than trenching.
No matter course you select to guard your hoses and cables, first take into account the security that the safety affords, in addition to the affect on the surroundings. Then, youâll want to take into account the entire price to assemble, keep, and deconstruct the safety â together with prices of harm to the strains being protected or the automobiles which might be concerned. You might conclude, as many others have, that utilizing a âfor purposeâ metal highway crossing gives the bottom price together with probably the most peace of thoughts.
