Is any toxic gas produced when acetic acid and limestone react?

I posted a message a week or so ago asking about the reactions of acetic acid and vinegar (5%) acidity with limestone. As a follow-up, is there any possible way you can mix any of these three substances to create a poisonous gas (at least poisonous to humans)?
Kate

Kate, Unless you freeze the CO2 and fire it at someone, it isn't much of a hazard. The vapor from concentrated acetic acid is of more concern. Excerpt from the Material Safety Data Sheet for acetic acid (from the Vermont SIRI MSDS collection):
LD50-LC50 Mixture: LD50:(ORAL,RAT) 3310 MG/KG 
Route Of Entry - Inhalation: YES 
Route Of Entry - Skin: YES 
Route Of Entry - Ingestion: YES 
Health Haz Acute And Chronic: ACUTE:DANGER!!!! CORROSIVE. CAUSES SEVERE
BURNS. MAY BE FATAL IF SWALLOWED. HARMFUL IF INHALED. COMBUSTIBLE. SYMPTOMS
INCLUDE SORE THROAT, VOMITING, DIARRHEA, BREATHING DIFFICULTIES, SKIN
BURNS, PAIN OR REDNESS, EYE WATERING & IRRITATION. CHRONIC:REPEATED OR
PROLONGED EXPOSURE MAY CAUSE DARKENING OF (EFTS OF OVEREXP)
Carcinogenicity - NTP: NO 
Carcinogenicity - IARC: NO 
Carcinogenicity - OSHA: NO 
Explanation Carcinogenicity: NOT RELEVANT.
Signs/Symptoms Of Overexp: HLTH HAZ:THE SKIN, EROSION OF EXPOSED FRONT
TEETH, AND CHRONIC INFLAMMATION OF THE NOSE, THROAT, AND BRONCHIAL TUBES.
Med Cond Aggravated By Exp: PERSONS WITH PRE-EXISTING SKIN DISORDER OR EYE
PROBLEMS, OR IMPAIRED RESPIRATORY FUNCTION MAY BE MORE SUSCEPTIBLE TO THE
EFFECTS OF THIS SUBSTANCE.
Emergency/First Aid Proc: CALL A PHYSICIAN. SKIN & EYES:IMMED FLUSH W/
PLENTY OF WATER FOR AT LEAST 15 MINUTES. INGEST:(DO NOT INDUCE VOMIT)!!!
GIVE LARGE QTYS OF WATER/MILK IF AVAIL. NEVER GIVE ANYTHING BY MOUTH TO
UNCON PERSON. INHAL:REMOVE TO FRESH AIR. IF NOT BREATHING, GIVE ARTIFICIAL
