Gas Chemical Formula COSHH long-term limit ppm (8hrs) COSHH short-term limit ppm (10mins) Effects of high exposure
Ammonia NH3 25 35 - 200ppm: sneezing, salivation, and appetite loss  
- 30ppm: some respiratory signs, reduces mucociliary escalator
Carbon Monoxide CO 50 300 Abortion in pregnant sows
Carbon Dioxide CO2 5000 15000 100,000 narcotic used in slaughterhouses
Hydrogen Sulfide H2S 10 15 - 20ppm: low appetite, fear of light, and nervousness  
- Sudden exposure to 400ppm is lethal
- Low concentration- smell of rotten eggs
- High concentration- no smell

*Expensive detectors are NOT needed for ammonia

[NH3] Typical Human Effects
Below 5ppm No effect
5-10ppm Detect its smell
10-15ppm Causes mild irritation
Above 15ppm Causes eye irritation and tear flow


  • Air must contain less than 10mg/m3 of inhaled dust
  • Respirable dust particles are 1.6 to 3um in size
  • Particles > 3μm in size are removed by upper respiratory tract (URT)
  • Particles < 1.6μm in size blow in and out of the entire respiratory tract

The dust visible in the sunlight shaft (pictured above) is respirable dust which is a major threat to your pig's respiratory tract.
