IANAL, blah blah blah, etc...
www.leg.state.or.us is your friend 
166.360 through 166.385 supposedly cover "POSSESSION OF WEAPON OR DESTRUCTIVE DEVICE IN PUBLIC BUILDING OR COURT FACILITY", but 382, 384 and 385 say nothing specific about public buildings and seem to be general in nature. I see nothing specifically defining "poison gas" besides being categorized under Destructive Devices, but tear gas and similar have their own definition:
163.211 Definitions for ORS 163.211 to 163.213. As used in ORS 163.211 to 163.213:
(1) “Corrections officer” and “parole and probation officer” have the meanings given those terms in ORS 181.610.
(2) “Mace, tear gas, pepper mace or any similar deleterious agent” means a sternutator, lacrimator or any substance composed of a mixture of a sternutator or lacrimator including, but not limited to, chloroacetophenone, alpha-chloroacetophenone, phenylchloromethylketone, orthochlorobenzalmalononitrile, oleoresin capsicum or a chemically similar sternutator or lacrimator by whatever name known, or phosgene or other gas or substance capable of generating offensive, noxious or suffocating fumes, gases or vapor or capable of immobilizing a person.
(3) “Tear gas weapon” includes:
(a) Any shell, cartridge or bomb capable of being discharged or exploded, when the discharge or explosion will cause or permit the release or emission of tear gas or oleoresin capsicum.
(b) Any revolver, pistol, fountain pen gun, billy or other form of device, portable or fixed, intended for the projection or release of tear gas or oleoresin capsicum. [1995 c.651 §1]
Note: 163.211 to 163.213 were enacted into law by the Legislative Assembly but were not added to or made a part of ORS chapter 163 or any series therein by legislative action. See Preface to Oregon Revised Statutes for further explanation.
163.212 Unlawful use of an electrical stun gun, tear gas or mace in the second degree. (1) A person commits the crime of unlawful use of an electrical stun gun, tear gas or mace in the second degree if the person recklessly discharges an electrical stun gun, tear gas weapon, mace, tear gas, pepper mace or any similar deleterious agent against another person.
(2) Unlawful use of an electrical stun gun, tear gas or mace in the second degree is a Class A misdemeanor. [1995 c.651 §2]

163.213 Unlawful use of an electrical stun gun, tear gas or mace in the first degree. (1) A person commits the crime of unlawful use of an electrical stun gun, tear gas or mace in the first degree if the person knowingly discharges or causes to be discharged any electrical stun gun, tear gas weapon, mace, tear gas, pepper mace or any similar deleterious agent against another person, knowing the other person to be a peace officer, corrections officer, parole and probation officer, firefighter or emergency medical technician or paramedic and while the other person is acting in the course of official duty.
