Portable Ventilation Equipment and Ignition Hazards .63FOREWORDThis Standard describes fundamental good practices rel

12、ated to the design, manufacture, labeling,use and application, as well as maintenance and testing of portable ventilation systems used forthe control of airborne contaminants or environmental conditions. Intended users of this Standardinclude owners of facilities, designers and manufacturers of port

13、able ventilation equipment,employers, industrial hygienists and safety professionals, maintenance personnel, and end users.This Standard is compatible with other recognized standards of good practice.This Standard is new. It intends to address a long-standing need in the ventilation arena. Portablev

14、entilation is a broad and complex subject. Much of what applies to portable ventilation systemsdoes not apply to fixed (in-place) systems and vice versa. Use of portable ventilation equipmentoccurs in many applications: confined space (sewer) entries; collection of welding plumes; main-taining negat

15、ive pressure in structures during asbestos, lead, and mold remediation; and control-ling emissions from spray painting and abrasive blasting, to name just a few. This equipment is usually unobtrusive, often just another piece of clutter in surroundings crowdedwith other portable and mobile equipment

16、 and tools. The environment in which much of this equipment is used is rough and tumble. These units can beused in any kind of condition and unpleasant weather. They can be thrown or kicked in frustration,dropped off trucks, and accidentally run over. These types of units require solid construction.

17、 Thus,design and fabrication may require incorporation of subtle features such as abuse-tolerant bondingfrom the electrical box to the frame to the ground connection through the electrical cord. Safetyfeatures must provide reliable protection in situations of high abuse.Portable equipment comes in a

18、ll shapes and sizes, ranging from the home built to the shop built tothe factory built, and the utilitarian to the elegant. Very little, if anything, exists in standard text-books on ventilation about this subject. Yet, the subject is far more complicated than meets the eyeof the casual observer.The

19、 Standard is presented in a two-column format. The left column presents requirements of theStandard; the right column clarifies and explains the requirements and provides information on howto comply with them.Appendices supplement information provided in the Standard. This Standard presents minimum

20、requirements adaptable to the needs of the user establishment.Demonstrably equal or better approaches are acceptable. When deviating from the Standard, theresponsible agent should provide documentation. Suggestions for improvement of this Standard are welcome. The Committee will carefullyconsider al
