<br />LOWER FLAMMABILITY LIMIT, THE SYSTEM SHALL AUTOMATICALLY SHUT
<br />DOWN THE SPRAYING OPERATION, SWITCH THE VENTILATION SYSTEM TO 100 PERCENT OUTDOOR EXHAUST
<br />AND SOUND AN ALARM. CFC
<br />2404.7.2.
<br />15. VENTILATION SYSTEMS SHALL BE DESIGNED, INSTALLED AND MAINTAINED SUCH THAT THE AVERAGE AIR
<br />VELOCITY OVER THE OPEN FACE OF THE BOOTH, OR BOOTH CROSS-SECTION, IN THE DIRECTION OF AIRFLOW
<br />DURING SPRAYING OPERATIONS SHALL NOT BE LESS THAN 100 LINEAL FEET PER MINUTE. CFC 2404.7.3.
<br />16. PORTABLE FIRE EXTINGUISHERS SHALL BE PROVIDED FOR SPRAYING AREAS IN ACCORDANCE WITH THE
<br />REQUIREMENTS FOR AN EXTRA (HIGH) HAZARD OCCUPANCY (E.G., 4-A:40-BC WITHIN 30 FEET OF THE
<br />BOOTH). SEE CFC STANDARD 10-1. CFC 2404.4.1 AND 906.
<br />17. SPRAY BOOTHS AND SPRAYING ROOMS SHALL NOT BE ALTERNATELY USED FOR THE PURPOSE OF
<br />DRYING ARRANGEMENTS WHICH WOULD CAUSE A MATERIAL TO INCREASE THE SURFACE TEMPERATURE OF
<br />THE SPRAY BOOTH OR ROOM UNLESS USED FOR AUTOMOBILE REFINISHING IN ACCORDANCE WITH SECTION
<br />CFC 2404.6.1 AND 2404.6.1.2.2
<br />18. HOUSEKEEPING, MAINTENANCE, STORAGE AND USE OF HAZARDOUS MATERIALS SHALL BE IN
<br />ACCORDANCE WITH SECTIONS 2403.3,
<br />2403.4, 2404.5.1 AND 2404.5.2.
<br />19. WASTE CANS: APPROVED METAL WASTE CANS EQUIPPED WITH SELF-CLOSING LIDS SHALL BE PROVIDED
<br />WHENEVER RAGS OR WASTE ARE IMPREGNATED WITH FINISHING MATERIALS. SUCH RAGS AND WASTE SHALL
<br />BE DEPOSITED THEREIN IMMEDIATELY AFTER BEING UTILIZED. THE CONTENT OF WASTE CANS SHALL BE
<br />PROPERLY DEPOSITED OF AT LEAST ONCE DAILY AND AT THE END OF EACH SHIFT.
<br />20. LIMITED SPRAYING AREAS SHALL BE IN ACCORDANCE WITH CFC 2404.9 AIR MAKEUP AND FLAMMABLE
<br />VAPOR AREA EXHAUST SYSTEMS SHALL NOT BE INTERLOCKED WITH THE FIRE ALARM SYSTEM AND SHALL
<br />REMAIN IN OPERATION DURING A FIRE ALARM CONDITION. EXCEPTION: SUCH VENTILATION TO BE
<br />DISCONTINUED WHERE THE TYPE OF FIRE-EXTINGUISHING SYSTEM USED REQUIRES IT. CFC 2404.8.2.
