NFPA 15, 68, and 69 refer to codes and guidelines which are formulated through mutual agreement for standard development procedures. They are allowed by the American National Standards Institute. The procedures incorporate people representing different opinions and concerns to attain a compromise on fire and other safety matters. In this paper, the NFPA 15, NFPA 68, and NFPA 69 are compared and contrasted on how they deal with explosive hazards.
NFPA 15 offers the least required necessities for the design, set-up, and system acceptance tests for the water spray fixed devices for fire protection. The code details all that is needed for intervallic testing and maintenance checks for the super speed water spray fixed devices. Here, water is used in a programmed manner, accepted mold, size, speed, and compactness. It is then released from specially created nozzles and objects. Water spray devices are useful for unique fire protection dangers since they can be exclusively created to offer efficient fire control, extinguishment, security, or contact safety. These devices are used with other forms of explosive protection but can be independently utilized. The devices are designed in consideration of the kind of danger in question and the primary uses of the devices. Hence, for proper variations in the properties of the spray nozzles, the systems are expertly created, set up, and checked for performance.
On the other hand, NFPA 68 addresses explosive hazards through deflagration venting. This code particularly deals with the design, site, setting-up, performance checkups, and utility of devices which create vents for the combustion gases and pressures which develop from a deflagration in an enclosed place. This is in a bid to control structural or mechanical damages. Basically, the primary goal for the code is to offer a system for the creation, setting up, and performance check-ups for the deflagration vent devices and all the relative elements needed for proper operation.
While the NFPA 15 and NFPA 68 codes appear to offer appropriate devices for the control of explosive hazards, NFPA 69 offers the best standards and guidelines on the explosive prevention devices. Hence, it should be noted that while the first two show these systems, the latter gives guidelines on how they have to be maintained, designed, and set up. NFPA 69 gives the least required essentials for the installation of devices for the control of explosive hazards in areas having combustive concentrations of combustive gases, dischargeable vaporizations, and several other hybrid combinations. Essentially, engineers and other experts get the most important information and knowledge on how to design the systems, operating human resources, and the officials involved.
The code outlines the least accepted levels of dependability for the explosive control devices, the control of explosive hazards, and that the regulative systems in place are created and set up following the best requirements. Basically, the best requirements outlined under this code are control of performance maintenance through testing; checking for the performance of the explosive control systems by third parties, who are internationally respected for their services, change management, constant tryouts, and performance checkups. In addition, any tests that have to be done on the systems have to be commissioned and proper documentation is done for all the designs that are created for the explosive hazards control devices as advised by NFPA 15 and NFPA 68.
