Good Morning

 

I’m a designer at sprinkler company in Poland

 

Our membership number is 3162872.

We have a technical issue.

 

We have to protect tire storage in racks by the sprinkler installation. Storage is in a double and single raw racks. Storage height is above 3.7m but less than 6,1m.

In NFPA 13 edition 2019 we found only information about maximum distance between sprinkler 2,4m according to point 25.5.2.1.3

 

Questions

  • What a figure we have to use to protect tires?
  • One line in longitudinal space is enough ?
  • What is a maximum vertical distance between levels of sprinklers in racks. We didn’t find references

 

Could you help us?
