Gee, the disadvantages of coming to the conversation late.
Firstly, I have a basic knowledge of DGs (Dangerous Goods, yes I will spell it out using capitals here) from learning a half-course at uni in Occupational Toxicology. A heavy bag is dangerous but that does not make it a Dangerous Good. Otherwise, heavy bags would need to be transported with forms and the like (rather than merely just repacked/reorganised). I see about 20+ posts have been wasted trying to iron out the semantics of two words.
I wish some of you can argue with my dad. He gets very furious when he is told that his cabin baggage or checked baggage is too heavy and he is told to shift some weight around, when his argument is that it doesn't matter where the weight is on the ****ing plane, the plane will weigh exactly the same. Anyway, I digress....
I didn't actually know that the security companies are subcontracted by the airlines (as opposed to by the airport authority itself). To that extent, if airlines want to push the responsibility of checking bags on them, fine, except fundamentally it slows the security screening process, and unlike explosives checks would it be really fair to make bag checks random?
On another note, it is almost too easy to get away with more cabin baggage and/or the wrong limits being enforced. For one, domestic passengers flying QF are entitled to:
- 2 x 105cm bags
- 1 x 105cm bag + 1 x garment bag
- 1 x 115cm bag
Each piece must not exceed 7kg. The security people have to make sure they remember all three sets of rules.
Now I did make a slight boo-boo there. These allowances only apply if you are flying QF metal on a
jet. If you're on a turboprop, the allowance is only one piece at 4kg. Now how do you suppose the security staff check for that one?
Then, as some people said, what if you are not flying and just visiting the lounge / seeing friends or relatives off? Then again, how are the security people going to know otherwise unless they follow you all the way to the gate and then possibly charge you for lying?
A whole bunch of these issues would be solved if they moved baggage checking to the gate. Of course, unless everyone was pre-checked before boarding*, the boarding process would be very much slowed.
What they should also do is provide a test frame which is raised higher above the floor. Except for those people who are justifiably incapacitated, if someone cannot lift their carry-on baggage there's a good chance it'll be in breach of carry-on regulations.
So, to round off, in answer to the OP question - is it the job of security to weigh pax baggage?
Prima facie, no. But since they appear to be "in the right position to do the job"........
* One model that I can see is that at the service desk, gate desk and lounges, test frames are given and pax prove to a staff member that their carry-on is within limits. A note is then made on the manifest that the carry-on passes. Later, when the pax are boarded, those pax whose carry-ons have not been tested are held back and not boarded until their carry-ons have been tested and permitted. This is where a couple of boarding lines would be very useful.
