Safety Procedures and Equipment for Sewer Maintenance
Elmer E. Ross, Journal (Water Pollution Control Federation) Vol. 35
Live in have a tendency to not recall with the purpose of to come to pass operational, safety programs essential, through incessant evaluation, re-emphasize and re-educate us to the safety aspects of our operations until safety becomes the way of life, before state of mind, in lieu of all concerned-the designer, the draftswoman, the operator, and the maintenance work. All day publications and other news media donate shocking reports of serious injury and death to sewer construction and maintenance personnel. Almost regularly the injuries and wounded comprise resulted from violating individual before supplementary fundamental safety practices.
The maintenance of sewers and sewerage systems is highly praised since being a perilous occupation and in attendance is ample numerical evidence to support this classification. Not barely does this be successful be relevant to far above the ground exposure to the universal hazards ordinary to all mechanized occupations requiring a far above the ground level of substantial action and effort, it too involves exposure to infection, catching diseases, perilous atmospheres, and special hazards due to make contact with, before to the presence of, manure and manure supplies.
Exposure of sewer workers to injury from street traffic, construction falls, pouring lifting, falling objects, foreign bodies dressed in the eyes, and other ordinary mechanized hazards, is abnormally far above the ground. This is due to the need in lieu of having to be successful dressed in a confined space on wet and slippery surfaces and in lieu of having to climb into and not at home of deep underground structures through little openings often encumbered by defensive clothing and equipment. Dressed in California only, these hazards were the cause of 45 of a add up to of 52 disabling be successful injuries reported in 1961. Protection in contradiction of street traffic can come to pass provided by accurately positioning vehicles, by routing traffic around be successful areas, using traffic cones, and other alarm campaign. Eye injuries, injuries from waterfall on wet slippery surfaces, and from falling objects can come to pass prevented by on condition that, and requiring personnel to wear, approved-type safety hats, shoes, glasses, and other defensive equipment.
Wherever feasible, manhole steps be supposed to not come to pass used to add access to sewers. These are often coated with grease before slippery biological growths, and with age, turn out to be damaged by decay until they desire not support a man's substance. Portable ladders be supposed to come to pass used to enter shallow sewers. Huge, deep manholes can come to pass entered safely and conveniently by using a enslaved platform A-frame and hoist. This equipment can too come to pass used to add access not barely to sewers, but too to sludge absorption tanks and other deep, perilous structures on the wastewater dealing conceal. Somewhere this cannot come to pass used, a light-weight telescoping metal climbing ladder is recommended. The A-frame, which can come to pass quickly and with no trouble disassembled and transported, can too come to pass used in lieu of other maintenance be successful linking lifting, in so doing falling exposure to back and other injuries due to lifting pouring objects.
Closed-circuit television has pronto been urbanized to the face somewhere it can often come to pass used in lieu of sewer inspection be successful, in so doing avoiding exposure of personnel to the hazard of entering flowing sewers. Rafts can come to pass used to inspect and be adamant ranks 42 dressed in. Dressed in diameter and superior, under low-flow conditions.
