Manufacturers of Thermal Insulation Prod ucts containing asbestos have for years been taking protective measures to eliminate exces sive exposures to inhalation of dusts that may be injurious. Based on the fact that all materials can be handled safely, the National Insulation Manu facturers Association recommends the follovV \ ing practices for handling and applying The</ mal Insulation Products containing asbestos and/or other potentially injurious materials to protect the worker. Insulation contractors and applicators 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 protection practices are strictly ob served.

A major source of excessive airborne dust is from loose materials, scrap and debris distributed throughout the job area and disintegrated fay trampling on, running over, etc. Much of the airborne contamination can be eliminated by exercising simple good housekeeping practices. Specific standards and practices designed for providing safe, clean and orderly working conditions should be defined. Efficient supervisory control, planning of systematic cleaning plus day to day follow-ap are the basic requirements for 'ist control and injury prevention. 4 Pipa and Block Insulations (corn'd) <3 Fabrication In Warehouse and Job Site Shops 1 Open and remove the material from cartons with care. Handle and stack pieces of material in 4 a manner that will avoid generating dust and breakage. 3 Mechanical dust collecting systems adequately designed to remove dust at the source should be installed on power-operated, fixed and portable equipment in the warehouse shop and/or in the job site shop. 4 All machines should be furnished with suitable waste containers for the collection of scrap and waste to prevent the material from falling on the floor and generating dust 5 Shop-fabricated pieces of Thermal Insulation such as fittings, segments, etc., should be placed in containers. Care should be taken when handling these pieces during piling, stacking and packing. 6 Containers should be closed after packing and remain closed until the material is used. 6 ri material -ill ecessary ials. rap, - 'Eterial ping, etc. ill create per *rably portable should be source. i Next Pg) Pipe and Slock insulations (cont'd) 3 i Application Procedures (Cont'd) 6 If conditions prevent collecting or t exhausting dust from the source, use exhaust blowers to provide general room air changes. 7 Avoid exhausting into other working areas. 8 In confined spaces, if mechanical exhaust ^ equipment cannot be used, "Respirators should be worn. 9 When wiring or banding insulation and applying jackets or facings, care should be taken to avoid generating excessive dust, C using the precautionary measures described above. 10 Surplus usable materials should be placed in cartons, which should be closed and returned to the warehouse.

Refer to the Sprayed Mineral Fiber Manufacturers Association for Sprayed Fiber Application Practices.* 1 The equipment and machinery to be sprayed should be shielded by adequate wind breaks and, where practicable, drop cloths to prevent excessive dust and contamination in adjacent areas. . 2 Workers not engaged in the spraying operations should wear ' Respirators when entering an area within 15 feet of the spraying ^ machine, nozzle or equipment. -'3 Where Sprayed Fiber Application Practices cannot be followed and excessive airborne dust is generated, it is recommended that portable mechanical exhaust ventilation be used to remove airborne dust Exhaust must be located to avoid contamination of other occupied areas. Application 1 All personnel in the immediate area engaged in the machine feeding and spraying operation should wear ' Respirators, whether in confined or open areas, ventilated or not ventilated. 2 'Respirators should be worn after the spraying operation has been concluded and until the generated dust concentration has cleared. t F or copy o f Practice*, v m te (a Executive S te n ta r y , Sprayed Filter M anufacturer* A M tia, P O.

Stripping Area Careful work methods, use of proper tools, and wetting' down will minimize excessive dusts in stripping operations. 1 The area in which stripping takes place should be confined by means of curtains, portable partitions, etc., to prevent excessive dust contamination In adjacent areas. 2 If area cannot be confined, only workmen engaged in stripping should be permitted in the work location. Stripping and Tearing Off 1 All personnel in the stripping area engaged in tearing off, handling, cleaning and disposing of material should wear Respirators. 2 Where circumstances permit, materials should be wetted down prior to and during removal. 3 Where applicable, portable mechanical exhaust ventilation should be used to remove airborne dust 4 Avoid unnecessary re-handling of scrap.

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. The efficiency and effectiveness of ( respiratory equipment is dependent upon proper care, cleaning and maintenance. A systematic procedure should be established , to assure that this is done.

( 1 Open the bag wide enough to empty without shaking. 2 When dumping, keep bag on the mortar box mixing level to avoid dropping. S Do not shake bags. 4 Place empty bags in a container, wet down contents, and discard. 5 Mixing area should be well ventilated but free from heavy drafts that will cause dry material to become airborne. 6 Material should be mixed in a mortar box, pail or tub and not on the floor. 7 Wet the material and mix into a slurry as quickly as possible. 8 When mixing cement in a confined space where proper ventilation is inadequate, Respirators should be worn. Cleaning 1 Bag breakage, cleaning up dry cement and discarding bags at the mixing area should be done in the same manner as recommended under Warehousing, Storage and Handling. 2 Wet down tools, mortar boxes, wheelbarrows, mixing containers, and any spillage before scraping and cleaning. 3 Cements should be handled wet whenever possible. Wet material will create no dust problem. + *# K a / Mis.**-approved respirator*.
