Talk:Carbon dioxide/to do

Here are some tasks awaiting attention:

Cleanup : *More and better references (more print references needed)
- Use a consistent style of referencing (inline seems the best)
- Tidy up external links
- Expand : *On other planets (e.g. Venus)
- More on plants (Mainly their carbon fixation e.g. CAM, C4 plants)
- More on past levels of CO2 and how they changed (e.g. earth's early atmosphere, the role of cyanobacteria)
- Write a full lead section when finished (~3 paragraphs)
- Verify : Verify disputed claims and statistics

Vital topic for any encyclopaedia, but is in poor shape. Pending a split, and has several lists of things that need doing, if anyone is interested? — Jack · talk · 06:08, Wednesday, 25 April 2007
Especially with all of the discussion of it in Global Warming contexts recently. ~ Bigr Tex 14:58, 3 May 2007 (UTC)[reply]
Way too long "see also" list, should and could be incorporated into prose. Punkmorten 13:32, 18 May 2007 (UTC)[reply]

The Fire Extinguisher Entry is outdated and wrong.

CO2 IS toxic at concentrations higher than 5%. Design Concentrations for Room Flooding systems with CO2 are 40%+ so CO2 is not suitable for occupied spaces. CO2 Flooding Systems are not supported for use in occupiable spaces though many countries such as USA and other third world countries still misuse CO2 in Fire Suppression Systems because it is cheap. The NFPA supports the use of CO2 on electrical hazards though it is not supported globally because CO2 can cause over pressurization, thermal shock, electrical component damage and has human health/toxicity issues. The NFPA organisation is not the definitive word/authority on Fire Suppression it is just one of many organisations involved in making standards for Fire Protection. The NFPA is really relevent only to the USA. USA codes and standards are typically only relevent to the USA so should not be referenced as the main global Fire standard on a site like wiki which serves a global audience (unless wiki is only for Americans). Though CO2 was used many years ago to protect enclosed spaces on Ships, this is extremely outdated. CO2 has caused fatalities on ships in Navies and merchant fleets that it is now superceded in this application by using extinguishants that support human life at design concentrations such as HFC-227 or Novec-1230. Unlike other countries, America and other third world countries still allow the use of CO2 in some applications where humans can be present because CO2 is cheap and installations are not monitored/controlled.
