HKU Lecturer Karen Mak told RTHK that tear gas can be kept for around three to five years, but may decompose over time. Since tear gas canisters are activated by heat, the heating process may then produce toxic gases such as phosgene and cyanide.

Photos have circulated online purporting to show tear gas canisters used past their expiry date, but police have so far declined to comment on whether expired tear gas was used.

Hong Kong reporters coughed blood and developed rashes after tear gas exposure, doctors say.
