19、 fired boilers are loss of water (low water), furnaceexplosion, overpressure, and overtemperature. Principal causes of accidents to automatically firedboilers are lack of proper controls and safety devices, lack of adequate maintenance, improperlytrained operators, failure to test controls and safet

20、y devices, and complacency on the part of theoperator due to long periods of trouble-free operation. It is believed that improved instrumenta-tion, controls and safety devices, proper operating procedures, and a clearer understanding ofinstallation requirements by the manufacturers, installers, and

21、operators can greatly reduce thechances of personal injury, damage to property, and loss of equipment from accidents.It should be pointed out that any governmental jurisdiction has authority over any particularinstallation. Inquiries dealing with problems of a local character should be directed to t

22、he properauthorities of such jurisdictions.Safety codes and standards are intended to enhance public health and safety. Revisions resultfrom the committees consideration of factors such as technological advances, new data, andchanging environmental and industry needs. Revisions do not imply that pre
