What is Carbon Dioxide (CO2)?

  • Molecular Formula: CO2 (Not to be confused

with Carbon Monoxide (CO)

  • Specific Gravity (SG)/Vapor Density: 1.53

times heavier than air (SG = 1)

  • Appearance: Colorless
  • Odor: Odorless but with a slightly pungent
  • dor and biting or acidic taste may be noticed

at high concentrations

  • Always present around 400 ppm in our

atmosphere

  • The second most widely delivered and used

compressed gas after Oxygen – Very Common

slide-8
SLIDE 8

Effects of Carbon Dioxide (CO2)?

  • A toxic gas often referred to mistakenly as only a simple

asphyxiant

  • CO2 can kill in two ways: Either by displacing Oxygen

(O2) or as a toxin in its own right

  • Target Organs: Respiratory system; central nervous

system; heart

  • Acceptable levels less than 600 ppm
  • General drowsiness at 1,000 – 2,500 ppm
  • Adverse health effects expected at 2,500 – 5,000 ppm
  • Slightly intoxicating, breathing and pulse rate increase,

nausea at 30,000 ppm

  • Headaches and sight impairment at 50,000 ppm
  • Unconscious at 100,000 ppm

How did we get here today?

  • Historically gas cylinders
  • f CO2 were filled at the

gas distributors’ facility

  • Approximately 20 years

ago the beverage industry developed a system to fill larger storage vessels on-site

slide-11
SLIDE 11

Where does the CO2leak?

  • Improperly vented to the outside of

the building

  • Leaking fittings, connections,

piping/tubing/hoses, or storage container plumbing

  • Leaking carbonators, syrup pumps, bag

in box (BIB) racks, etc.

  • Leaking beer keg connections and

equipment

slide-12
SLIDE 12

Reported incidents of CO2 leaks

  • November 2012 – Evacuation of a restaurant in

Brentwood Borough Pennsylvania. Patient complained of dizziness

  • September 2011 – Ten people hospitalized,

including two firefighters, and one fatality at a fast food restaurant in Pooler, Georgia

  • June 2011 – Evacuation of a fast food restaurant

in Dorchester, United Kingdom

  • May 2011 – Three hospitalized, including two

firefighters, at a fast food restaurant in Phoenix, Arizona

slide-13
SLIDE 13

Morereported incidents of CO2 leaks

  • May 2010 – Evacuation of a movie theater in Des

Moines, Iowa

  • July 2008 – Two hospitalized from an incident in

a bar in Benson, Nebraska

  • April 2008 – One fatality in a hotel in Victoria,

Australia

  • August 2007 – Fatality of a waiter at a restaurant

in Coronado, California

slide-14
SLIDE 14

Morereported incidents of CO2 leaks

  • January 2005 – Two fatalities, employee and

delivery driver, outside a fast food restaurant in Sanford, Florida

  • March 1998 – Two hospitalized and two

treated at the scene at a fast food restaurant in the U.S. (location unknown)

  • 1996 – Fatality of a delivery driver outside a

restaurant in Cincinnati, Ohio

Carbon Dioxide (CO2) Awareness

  • Denver Amended Section 5307

– Too General – Not Specific Enough – Input from gas industry – Input from Beverage and Restaurant Associations – Public meetings

slide-18
SLIDE 18

WHA T IS REGULA TED?

  • Systems with more than 100 pounds of CO2
  • Equipment including tanks, cylinders,

piping, tubing, fittings, valves

  • Automatic system shut-off valve(s)
  • Venting
  • Mechanical ventilation
  • Emergency alarm CO2 gas detection system
  • Warning Signage

Carbon Dioxide (CO2) Awareness

WHA T IS REGULA TED?

Carbon Dioxide (CO2) Awareness

  • Filling CO2 gases
  • Permits
  • Inspections and testing
  • Daily, monthly, semi-annually, and

annually testing

  • Records
  • Training of all employees

Who else has these CO2tanks???

  • Swimming pools
  • Agriculture grow rooms
  • Breweries / wine rooms
  • Sporting events

Carbon Dioxide (CO2) Awareness

Breweries / Wine Rooms

  • Carbon Dioxide (CO2) and Nitrogen (N2) gases are

used in beer dispensing

  • Nitrogen is:

 inert gas (typically non-reactive)  simple asphyxiant  Displaces oxygen  It is not a toxic gas at high concentrations like Carbon Dioxide

Inert Gas Awareness

  • Section 5309 Inert Gas Systems Used In

Commercial, Manufacturing or Industrial Applicatons

– pH Balancing – Food Processing – Laboratories – Medical Equipment (MRI) – Medical Treatment – Others

slide-36
SLIDE 36

Inert Gas Awareness

  • Section 5309 Inert Gas Systems versus

Section 5307 Carbon Dioxide (CO2) Systems

– Section 5307 is for Carbon Dioxide (CO2) only – Section 5309 is for all other inert gases – If CO2 is used for a non-beverage dispensing use, section 5309 refers back to 5307 – CO2 detection versus Oxygen detection

  • Challenges

– Implementation – Drawing submittals for new and existing – What type of permit to issue? – Inspections? By Whom? Building, Fire or both? – Enforcement?
