We have an in house course, which as you say is different than Warden training. However, it is more involved than warden training as we do not expect Wardens to see or deal with a fire - just assist in evacuation
The Fire Watching Course is low on scientific or technical detail. Instead it is laden with case studies to keep candidates awake.
Its is ALWAYS delivered by a competent person (or otherwise would not be compliant with the Fire Safety Order) in a laid back style which encourages partcipation from those attending as to their experiences. This is where a competent person is essential to be able to go 'off script'
The inputs is as follows:
Why bother with watchers? (CASE STUDY - fire on a construction site - hot works)
Legal (liability, duties and responsibilities - differences between employer and employee)
Triangle of fire. - Basic stuff
Methods of fire spread (convection, conduction, radiation, direct burning)
Speed of fire spread (practical factors which influence fire growth)
CASE STUDY - Fire in historic structure during works - with video and lessons learned section
Compartmentation
Fire alarm systems (how they are distend and what they aim to achieve - avoiding unwanted signals)
CASE STUDY - Hot works related fire in NHS premises
Safe systems ( permits, RAMS, removal or covering combustibles, ventilation, emergency plan, cover over breaks and calling 999)
Description of portable fire extinguishers (Water, foam, co2 , DP and blankets)
Safe methodology in use of extinguishers and dynamic risk assessment
Practical session (cold, no fire or simulated fire)
Summary and test (very easy test to ensure students have paid some attention)
