### Recommended Personal Protective Equipment and Safe Handling Procedures When Using Isocyanate containing MOR - FREE ® 

### Adhesives Caution: Several MOR

- FREE ® adhesives contain isocyanates which are known skin and respiratory sensitizers. Every effort should be ma de to prevent exposure by any route by means of engineering controls. Personal protective equipment should be considered a last resort approach to employee protection. Once cured, isocyanate

- containing MOR

- FREE adhesives are non

- hazardous. 1. Eye Protection : Wear safety glasses during routine operations. When there is the potential of a splash, wear chemical splash goggles and a face shield. 2. Work Clothes : Wear long pants and long

- sleeved shirts. If work clothing is contacted with isocyanate

containing material s, it should be changed immediately and properly discarded if grossly contaminated. If clothing can be cleaned it should be either laundered on site by employees or with help from a commercial laundry service whose employees have been informed about the p otential hazards of the possible contamination. Any work clothing believed to have been contaminated should not be laundered at home. Procedures for handling contaminated work clothing should be developed and followed. 3. Work Shoes : Wear steel

- toe safety sh oes when there is the potential of foot injury. 4. Hand Protection : Nitrile gloves are recommended for protection against isocyanate

- containing materials. Before removing contaminated gloves, water rinse them and remove them without touching the outer surface with unprotected fingers. Allow gloves to air dry to cure unreacted isocyanate, and discard contaminated gloves as non

- hazardous trash. (www.bestglove.com, www.ansellpro.com) 5. Skin Cleaning : If skin is contacted with isocyanate

- containing materials, immedi ately wash with polypropylene glycol, a polyglycol skin decontamination product, or corn oil. Then wash the affected area thoroughly with soap and water. 6. Respiratory Protection : If air monitoring has shown that air concentrations of isocyanates are greater than 5 and less than 50 parts per billion parts of air (ppb), wear a full facepiece air

- purifying respirator equipped with an organic vapor cartridge and N95 prefilter. If the airborne isocyanate concentration is above 50 ppb or is unknown, a positive

- pre ssure full facepiece airline respirator or positive

- pressure self

contained breathing apparatus (SCBA) is required. Ensure that respirator wearers have been fit tested. (www.3M.com/occsafety, www.MSAnet.com) 7. Engineering Controls : Avoid generating mists and vapors by using closed systems. When mists and vapors are released, control then by means of enclosures and ventilation systems. 8. Ventilation : Use local exhaust ventilation for the control of airborne isocyanates, that is ventilation that collects vapor an d mist releases at the point of their evolution and exhausts then from the workplace. A capture velocity of 100 fpm is required for vapors and 150 fpm for mists at the point of release. Consult the latest edition of Industrial Ventilation , A Manual of Reco mmended Practice published by the American Conference of Governmental Industrial Hygienists for information on the design, installation, use, and maintenance of exhaust systems.
