There are a lot of references on static electricity which will provide the information. Two good books are:

Avoiding Static Ignition Hazards in Chemical Operations
http://www.wiley.com/WileyCDA/WileyTitle/productCd-0816908001.html

Electrostatic Ignitions of Fires and Explosions
http://www.wiley.com/WileyCDA/WileyTitle/productCd-0816908001.html

There are codes and standards in most countries, for example, NFPA 77 "Recommended Practice on Static Electricity". There are equivalent codes and standards in other countries (UK, Australia, New Zealand, for example).

There is an enormous literature on static electricity, including at least one journal devoted to the subject (Journal of Electrostatics). I have over 100 references in my own files.

One good article: Expert Commission for Safety in the Swiss Chemical Industry (ESCIS). "Static Electricity: Rules for Plant Safety." Plant/Operations Progress 7, no. 1 (January) (1988): 1-22.
