What are the requirements for suppression in an abrasive blast booth?
Abrasive blasting, that produce a spark, a flame, or heat could also be included as hot work. These operations are potentially dangerous, depending on the type of work being performed and the environment in which it is performed. In contrast; NFPA-51B could be referred. Adequate ventilation must be provided wherever welding, cutting, and other hot work are performed to protect the operator from inhaling noxious gases and fumes. Potentially hazardous materials might exist in certain fluxes, coatings, and filler metals. In some cases, general natural draft ventilation is adequate.
A protection system may become impaired for a number of reasons (e.g., maintenance, renovation, construction, equipment failure, or failure to reactivate the system or device). Facility managers and loss control managers should be notified immediately of any impairments during normal working hours. During off-hours, depending on the seriousness of the impairment, these same individuals may still want to be notified. This procedure should be addressed in detail in the company policy.
Refer NFPA - 10, NFPA - 51, NFPA - 51B etc. in align with same.
Hope this is helpful.
