  1. In Cahoots – Interconnections of Fire Protection Systems with Ancillary Equipment

    Leave a Comment

    Fire protection is an expanse that I am both fascinated by and passionate about. To prove it, I could show you my sprinkler collection… the old ones, the new ones, the sizes, the features!  But instead, I will share some information to show you the relationship between fire protection systems and other systems that you may have never thought about!

    Fire protection, suppression, and alarm systems often do not act alone. They can be in cahoots with life safety systems or other equipment or building systems to mitigate fires and help firefighters. Many, but not all, of these functions are associated with fire alarm systems. Many, but not all, of these functions are customary and expected. Some of these functions will automatically reset when the alarm or system is reset, but not all! (more…)

  2. Heavy Machinery Fires Caused by Hydraulic Hose Failures

    Heavy machinery fires are often caused by hydraulic hose failures.  Pressurized hydraulic fluid escaping from a failed hose assembly can be atomized into a fine spray that can be ignited by heated engine surfaces such as the engine exhaust or turbocharger.

    Hydraulic hoses often fail due to age and wear, requiring regular inspection and replacement of hydraulic hoses to prevent failures. Hoses may also fail if they are misrouted.  Misrouting can lead to the hose being pinched or causing it to chafe against a sharp metal surface. (more…)
