In a historic action, the Environ* mental Protection Administration and the Department of Air Resources cf New York Gty have promulgated Interim orders governing the spray ing on City construction sites ol any insulation material containing as bestos. First Such Action The orders went into effect April IS- They detail the steps that must be taken by spray contractors during application. These slept will mini mize exposure to spray applicators, to other construction workers on a job site, and also to tbe general population living or working nearby. This action by New York Gty is the first such in the United Stales. It brought to fruition a cooperative Medicine's Insulation Industry Hy- `ene Research Program, New York tv's Department of Air Resources, and various industry groups which began last summer. As part of this cooperative effort, a joint program of asbestos sampling and analysis was initialed by Mount Sinai and tbe Department of Air Re sources last July. At the same time the Sprayed Mineral Fiber Manufac turers' Association and the New York Gty Plasterers' Association met to establish industry safety practices and control procedures for spray ap plication.

In addition, consultation on vari ous aspects of the problem of spray insulation took place between UHRP ataff and building owners, architects, general contractors, and, especially, The handling of asbestos insula tion products presents a health haz ard not only to the insulation work ers but also (because of tbe confined areas) to the allied shipbuilding trade workers. Dr. Heimann and Mr. Reitze found that the three most serious hazards appear to be 1. the extreme dustiness during re moval of old insulation 2. an almost total lack of ventila tion in confined spaces S. tbe spread of dust from work areas into other regions of the ship.

To develop improved methods for minimizing ex posure of insulation workers to dusts and fumes encoun tered in their work. 2. To disseminate knowl edge of these improved methods of dust control wherever they may be ap plied advantageously and to offer cooperation, advice and assistance toward their universal adoption.

The interim orders will remain in force until adoption of final regula tions following public hearings. The bearings are to be beld within six weeks, according to Jerome Kretcbmer, newly appointed New York Gty Environmental Protection Adminis trator. The new rules include require ments that (a) any spray area be completely enclosed bv tarpaulins, (b) the area be vacuum-cleaned after application, and (c) insulation in air circulation plenums or ducts containing asbestos be coated with a seal ant to preclude erosion of asbestos-containing material into the air of the building. (See page 3 for complete regula tions.) Some Contractors Made Effort Dr. Robert N. Rickies, New York City's new Commissioner of Air Re sources, emphasiaed the need for spe cific procedures that are enforceable and noted that voluntary measure* to reduce environmental exposures were not uniformly followed. "Some contractors," be added, "made an effort to /contain their apray operation." (See Spring 1970 issue of Progress Reports for atory on World Trade Center.) "Other op erators, however," he went on, "made only minimal efforts at containment We also found that cleanup of waste was a serious problem everywhere, with workers of all trades being ex posed continually to the debris of spray fireproofing insulation." Dr. Irving J. Selikoff, IIHRP Di rector, endorsed the Gty regulations. "The technology for safe application of sprayed mineral fireproofing mate rial exists," he said. "However, the utilization of appropriate contain ment and cleanup techniques must be uniform throughout the industry if we are to succeed in solving the health problem of mineral fibers in urban air. "It is of importance, too, to note the Environmental Protection Ad ministration's concern with coatings of air plenums in buildings already in construction since it wishes to in sure that air in ventilating systems not be contsminated by foreign ma terial"  Text of the New Spray Rules: Foot examples of trade practice* the new rules ban: (top to bottom) Spraying without any containment at all; Inadequate tarping; asbestos* containing debris uncleared up; and spray materia] that bas been allowed to. fall down on to construction equipment. 1. Before the start of spraying operations all floo areas shall be swept broom clean. Before the application of asbestos-conuinin: material commences, the floor of the area shall be cleared of all objects, mate rial and equipment other than that employed in the application of the asbestos containing insulation or all objects, materials, etc. ahall be covered with plasti or plastic-coated tarpaulins in a manner that precludes the subsequent disperse cf asbestos particulates. 2. Tbe entire floor, or the part of the floor to be in sulated, shall be enclosed with plastic or plastic-coated tarpaulins in a manne; which shall preclude the escape of asbestos-containing material from the enelo sure. All interior open areas, such as elevator shafts, stairwells, etc. shall b enclosed in manner which shall prevent the escape of asbestos-containim material from the working area. "Suck effect" of tne shafts, suirwells, etc. shall be considered in providing proper enclosures. An enclosure will be con sidered satisfactory only if visible insulating material cannot escape from th enclosure. "3. Wet asbestos-conuining material which bas fallei to the floor shall he immediately swept up and placed in a container bavin; walls, bottom, and a tight cover strong enough to resist tearing or breakin; under normal handling conditions and clearly marked as containing asbestos waste. The contents of the aforementioned conUiners ahall not be transferrec to another container, but the eonuiner shall be placed directly upon a vehich for disposal at an approved site. 4. All floors will be vacuumed shortly after drying The vacuum cleaner shall conUin a strong, single-service, disposable inner ha; of durable material which shall be removed from the vacuum cleaner anc tightly sealed. The bag shall then be placed in a container of tbe type describee in paragraph 3, which shall thereafter be placed on a vehicle for removal anc disposal at an approved site. 5. Tbe materials used to form the enclosure shall be thoroughly vacuumed upon completion of the application of the insulation it the area. The entire floor area, all ledges and surfaces including tarpaulins upon which waste insulation material may have fallen, shall then be vacuumed or revacuumed before removal of the enclosures. 6. Enclosure* shall not be dismantled until the area bas been thoroughly vacuumed after completion of cpraying and cleanup. 7. AH areas used for opening bags containing as bestos insulating material and/or charging of hoppers shall be enclosed in such a manner that asbestos-containing insulating material shall not be per mitted to escape from tbe immediate area in whicb such activity takes place. 8. Signs shall be posted outride enclosures warning persons of the hazard of entering the enclosure without appropriate mask and other apparel 9. All persons involved in tbe spraying of asbestos at tbe rite must be furnished with Bureau of Mines approved respirators for pneumoconionic-producing dust and must be furnished with suitable coveralls which will be left at the site and thereby preclude the removal of asbestos from tbe site. No person shall be permittee in an area in which asbestos spray ing or handling has taken place until final vacuuming referred to in paragraph numbered "S" herein, unless such person is furnished with and wear* a Bureau of Mines approved respirator for pneumoconionic-producing dust and coveralls of the type described herein. Facilities shall be provided and procedures insti tuted and supervised that preclude the removal and dispersal of asbestoscontaining material from the construction site on the clothing or other appur tenances of persons leaving the area. 10. Any plenum or other structures coated with asbestos-containing insulation whicb is intended for use in the circulation of air in the building must be thoroughly cleaned of all debris antTwaste insula tion. All applied asbestos-containing insulation within a plenum or dud must be costed with a sealant which precludes exposure of the asbestos-containing materia] to the circulating air. 001023 I I v<r% r Cvr C3*` 1 V5&* i r l * Shipyards Tour Shows Hazards fG*xiartf fnm Istptfr) with Htlle natural ventilation. When tbe ahip is in operation, tbe air in these compartments is changed by means of a forced ventilation system. But during construction or rebuild ing. it remains stagnant. Fine dust and fibers put into the air by fitting and handling caldum (Hicale block or amosite blankets remain sus pended for hours. Insulating pipes with asbestos-containing materia] in ao confined a apace as this adds to the danger of breathing the dust. Confined Spaces Add Yet Another Danger Special Techniques Needed Dust generated by hand sawing or . fitting asbestos block can easily fall two or three decks through gratings. Tbe fibers thus deposited throughout an engine room may contaminate a ahip for months. Here the use of drop cloths or boxes to contain the dust can improve conditions measur ably. Some of the methods being devel oped by tbe Insulation Industry Hy giene Research Program for control ling asbestos dust at land-based building construction sites can be used aboard ships. It is evident, how ever, that further special dust control techniques will have to be developed . for the protection of all craftsmen in shipbuilding trades. Henae, the pri ority now being given to these prob lems by tbe IlHRP. Tbe Insulation Industry Hygiene Program has found answers to a number of problems in tbe asbestos insulation industry. Coaled calcium silicate pipe cover ing and block, plastic mixing ban, and proper use of dust collection de vices are some of tbe solutions. AH contain tbe dust at its source and all significantly reduce worker exposure to asbestos.' Portable Exhaust Systems Some insulation work, however, Eresents problems not easily solved y containment at the source. Ship board work, both application and tear out, and covering steam lines in confined tunnels are two such types of work. When there is poor ventilation in such work areas, removal of dust is made difficult and temperatures may rise to much above 100 F. To these twin problems, two complementary solutions are now being studied by I1HRP engineers--tbe use of port able exhaust systems and selfcontained air supply respirators. Cool Air to the Face In the confined apace of a tunnel, the use of an exhaust system at a nearby manhole can reduce both tbe dust level and the working tempera ture. In many cases, easily obtainable and inexpensive exhaust systems of less than 5000 cubic feet per minute capacity would suffice. IlHRP engi neers and industrial bygienists will be pleased to assist any contractor or union having apecific problems asso ciated with tunnel wore. Aboard ship, some use is made of portable low-volume exhaust systems, Designed principally to control fumes from welding operations. These sys tems, however, are ineffective in changing the large volume of air in most ship compartments. In some spaces having large vol umes of air, exhaust systems of suffi cient capacity to maintain dean air are either too costly or impractical to use. In these cases the solution may lie in self-contained batteryoperated air supply respirators. These respirators--far more com fortable to wear than standard ones --not only provide almost absolute respiratory protection from dust, but provide a cool stream of air to tbe worker's face. Batteries and motors have already been developed of suffi ciently light weight as not to be ob jectionable. Severa'Wliter models are under study by the IlHRP and full details and descriptions will be forth coming in a future issue of Insula tion Hygiene Progress Reports. 001024
