A member has reported an incident in which the water jet from a fire-fighting monitor hit an MF/HF whip antenna and damaged it.
What happened?
The incident happened during monthly testing of fire-fighting equipment. It was discovered that the horizontal travel of the fire-fighting monitor went beyond acceptable limits, allowing the water throw to hit and damage a nearby whip antenna. The testing was immediately stopped and damage was assessed.
Our member’s investigation revealed the following:
- Maintenance on this fire-fighting monitor had been carried out earlier by third party contractors.
- The root cause was determined to be incorrect adjustment of turning limit switch of the fire-fighting monitor.
- It was noted that it was important to regularly check the turning and elevation limit switches settings of fire-fighting monitors.
