SPRAY FINISHING |

Critical Concepts |

|
When spraying operations are strictly confined to reliable ventilation, such
as properly constructed spray
booths, the spray area
will ordinarily not extend beyond the booth enclosure. If, however, spray operations are
not confined to adequately ventilated spaces, the spray area may extend throughout the
entire room containing spraying operations. If this is the case, expensive electrical
devices and wiring would then be required throughout the entire room. It is therefore in the employer's interest to conduct spray operations in a spray booth or spray room in order to confine the vapors, mist, and residue and limit the area requiring use of Class I, Division 1 electrical equipment. Confining spray operations to a spray booth or room also increases the safety of the operation, facilitates maintenance and clean up, and provides a healthier working environment. The employer may also enjoy consideration for preferred insurance rates. |
