Chrome Plating and NFPA-13

Question asked by rwjsprinkler on Nov 16, 2015

We have a customer that has a chrome plating facility.  Most of the chemicals are nonflammable but they do store and utilize about 220 gallons of HCl (hydrochloric) Acid.  Our initial reaction was to cover this as an Extra Hazard II (0.40 over 2500).  I also notice that Chemical Plants are mentioned as being Ordinary Hazard Group II (0.20 over 1500).  We then thought possibly a foam system would blanket the area and help reduce the acid cloud but would add significantly to the cost.  I thought I would throw this out there and see how others might or have approached this.
