THE Office for Transportation Security (OTS) expanded the list of items banned on flights.

In a social media post on July 24, prohibited items now include chemicals and other toxic substances.

There are also add-on items under different categories such as improvised firearms, arrows and darts, hand/thumb cuffs, air tanks for diving, hoverboards and similar items, batteries and power banks, e-cigarettes and e-lighters.

The security office said some items are allowed inside cabins or hold baggage but subject to special instructions.

OTS also maintained its ban on liquid, aerosols and gels in containers exceeding 100 ml.

The expanded list is in line with international standards set by the International Civil Aviation Organization. — Vann Marlo M. Villegas
