Dear Station Members,

The news cutting given below may sound like an amusement to some of our Tree Professionals, but ISA HK/China have great appreciation for the efforts of the Firemen involved who have overcome difficulties & accomplished mission with their best trying methods.

The news below in Chinese described how when two 30 cm broken limbs of a 12 m tree rested in the canopy with potential to hit a house nearby, the brave Firemen had tried with Aerial Platform first but failed to reach the tree, & had to eventually use ladder to climb up to remove the broken branches. It was described that one lane of the two lane road was blocked several times for machineries deployment to cause traffic chaos, & the whole removal process took around 7 hours.

From the photo attached, it could be seen that the brave Firemen were wearing their usual fire-fighting uniform to use ladder to reach the broken limbs at approx. 5 m from ground to cut them down with their tools.

For emergency situation in HK, the usual scenario would be that the Police would be first informed & if the case involves public danger, .e.g. fire, traffic accident, suicide by jumping off the roof, etc., it would be the Fire Services which would be notified to come on site for rescue. This appears to apply to Tree Failure incidents as well.

On the other hand, the HK Firemen are usually equipped in the standard protocols of fire-fighting equipment & rescue tools. Their PPE are not by any international standard for Tree Climbing. Their saws are meant to cut steel body of crashed cars & metal gates for entry for rescue. Some of them have been trained to abseil from above to descend to grab suiciders from jumping off height, but not to ascend on rope in places where aerial lift & ladder can not be deployed.

Qualified Tree Workers are trained to access tree from ground on rope in event where aerial platform & ladder can not be used. They are trained to use chainsaws to cut wood, be it intact or broken. Qualified Tree Workers such as ISA Certified Tree Workers (CTW) have all got to learn & pass First Aid & Aerial Rescue before they are allowed to take their CTW exam. Our Independent Practicing Arborists (IPA, are masters of the situation & can operate chainsaws with Rigging at elevated heights to perform Tree Work.

At about the same time of this incident, the Station Manager had removed 2 no. of +15 m Casuarina trees outside Deep Water Bay amidst busy traffic without road blocking in under 3 hours with a gang of mere 4 Ground Workers. From the description & photo given below, he is confident to remove the said two limbs in under an hour without traffic blocking with his own crew & equipment.

Therefore, it is our admiration for the brave Firemen to conduct Tree Work for us to safe-guard public safety. On the other hand, if some of them have the interest to come & learn our Arborist skills for Tree Work, they may find it rewarding to do the work faster with less resources to cause less public inconveniences for the same result.

best regards,

Sammy Au
Station Manager
