Gene: ally these health sau-.y problems can be ch.ssitied into two major areas: (1) Physical coituci itltii i.iincral fibers. Contact with mineral fiber particles, as with many other fibers, may result in itchinp and "kin irritation. Particles may enter the eyes particularly during overhead applications. * (2) Exposure to excessive mineral fiber dosts. Mineral fiber products when cut or fabricated can produce some dust. Inhalation of excessive quantities of any dust, including mineral fiber dust, may result in some respiratory irrita tion. . * ,, 2 Introduction (confd) ' Manufacturers of Thermal Insulation Prod ucts Curtaining mineral fiber have for year* been taking protective measures to control ex cessive dust. The National Insulation Manufacturers Asso. ciatiim recommends the- following practices for handling and applying thermal insulation products containing mineral fiber to protect the worker. Insulation contractors and-applicatcs are urged to study these recommended practices , carefully and to see that they are observed by all workers handling insulation materials. As - with Safety Regulations, it is in the interest of both employer and employee to see that health safety practices are strictly observed. Prepared By COMMITTEE ON SAFETY AND HEALTH NATIONAL INSULATION I HOUSEKEEPING i PHYSICAL CONTACT WITH MINERAL FIBERS An oiganized housekeeping program should be maintained in all areas and on all opera tions at all times. A major source of excessive airborne dust is from loose materials, scrap, and debris dis tributed throughout the job area and disinte grated by trampling on, running over, etc. Much of the airborne contamination can be eliminated by exercising simple good house keeping practices. Specific standards and practices designed for providing safe, clean and orderly working conditions should be defined. Efficient supervisory control, planning of sys tematic cleaning plus day to day follow-up are the basic requirements for dust control and health protection. 4 * 1 If particles accumulate on exposed skin areas, do not rub or scratch. Remove the particles by washing thoroughly with soap and warm water. If water is not available, use dry wash materials (waterless soap and paper towels). 2 Long-sleeve shirts, long trousers and caps should be worn to cover maximum skin areas to avoid contact with the mineral fibers. Clothing should be loose fitting at collars, wrist bands and waist to eliminate skin irritation. 3 Barrier creams applied to exposed skin areas will provide protection against skin irritation. They should be used prior to handling the material and re-applied ac cording to instructions. 4 Good personal hygiene practices are essen tial. Thoroughly wash'exposed skin areas periodically and shower af end of work day. Change and launder work clothing fre quently, separate from other articles. 5 Proper work methods and practices that will eliminate creating excessive dust should be adhered to at all times. 6 Suitable gloves should be worn whenever handling abrasive materials. 7 Mineral fiber slivers that superficially penetrate the skin should be removed by thoroughly washing. Those embedded in the skin should be removed immediately and medical treatment administered. 8 Safety glasses, goggles or face shields should be worn when applying materials overhead or in areas where airborne parti cles may get into the eyes. 5 r ^~ * w .- )3 EXPOSURE TO EXCESSIVE MINERAL FIBER DUSTS 1 When mineral fiber materials are machine sawed, die cut, slit, etc., mechanical dust col lecting systems adequately designed to re move dust at the source should be installed. 2 Hand cutting, jacket stripping, etc., should be done in a manner that will create mini mal airborne dust. Proper method? and tools will help considerably to abate dust. 3 When working in confined spaces, dust col lecting systems adequately designed should be provided to remove dust from the source. If condition? prevent collecting dust. u>e ex haust blowers to provide general room air changes. Avoid exhausting into other work areas. If mechanical exhaust equipment car.not be used to remove excessive dust?. 'Respirators should be worn. 4 Whc-.n applying mineral fiber insulation overhead, workers should be clothed a? de scribed or. page 5, wear eye protection and 'Respirators if excessive dust is generated. 5 When mineral fiber thermal insulations are stripped from piping or r.*.h.--r surfaces, the area in which stripping tabes place should be confined by means of curtains, portable partitions, etc., to prevent excessive dust concentrations in adjacent areas. All work ers in the stripping area engaged in tearing off, handling, cleaning and disposing of ma terial should be clothed as described on page 5. wear eye protection and 'Respirators. Where circumstances permit, materials should be wetted down prior to and during removal. Where applicable, portable me chanical exhaust ventilation should be used to remove airborne dusts from the area. 6 Avoid unnecessary rehandling of scrap by locating disposal equipment as close to working area as possible. Do not permit ac cumulation of scrap and debris on floor and other surfaces. . Bureau of Mintt-approved respirator*. See page 7. 6 I RESPIRATORY EQUIPMENT Only U.S. Bureau of Mines-approved respira tory equipment is ivi-ommended for use. Ap proved respiiatory equipment should be used at all operations where dust control is not adequate. The efficiency and effectiveness of respiratory equipment is dependent upon proper care, cleaning and maintenance. A systematic pro cedure should be established to assure that this is done.

Only V.S. Bureau of Mines-approved respiratory equipment is recommended for use with asbestos, silica and other pneumoconiosis-producing dusts. Approved respiratory equipment must be used at all operations where dust control is not sufficient to maintain airborne dust concentration within allowable limits for asbestos and other pneumoconiosis-producing dusts, as . . established by governmental and professional agencies.
