calcium hypochlorite tablets

[cda]

A new large pool wants to store 50 buckets of the tablets.

need a little have not done a pool in a long time

they are trying to store outside

but want to put in in an area with no cover

any quantity limit for outside storage, weather proteciton needed?, does it have to be on or in a non combustilbe area/room?

anything else??

 

[Builder Bob]

Cda, what are the percentages of concentration for the proposed tablets?

 

[cda]

65 per cent

It would appear that per IFC section 5004.2.2 that unless the single container exceeds 550 pounds or aggregate weight exceeds 10,000 lbs that secondary containment is not required., I believe that this amount is under the threshold of requiring any special protection other than what manufacture's storage guideline are; which usually state avoid direct sunlight.

However, it does have a CERCLA RQ 10

Interesting note from CHRIS - 7.1 Grades of Purity: 70% (self-propagating); 65% (non propagating)

8. HAZARD CLASSIFICATIONS

8.1 49 CFR Category: Oxidizer

8.2 49 CFR Class: 5.1

8.3 49 CFR Package Group: II

8.4 Marine Pollutant: No

8.5 NFPA Hazard Classification:

Category Classification

Health Hazard (Blue).......... 1 2

Flammability (Red)............. 0 0

Instability (Yellow)............. 2 2

Special (White)................... OX

8.6 EPA Reportable Quantity: 10 pounds

8.7 EPA Pollution Category: A

8.8 RCRA Waste Number: Not listed

8.9 EPA FWPCA List: Yes

Anybody else have an OPINION??

dang have not looked at the 2012 IFC did not know it had so many chapters!!!!!!!!!!!!!!!!!!!!

65% CA(ClO)2 is a Class III oxidizer, Class 2 Unstable/Reactive and Corrosive solid. Assuming a bucket weighs 50 pounds, you have 2,500 pounds of Class III oxidizer. The MAQ under the 2012 IFC (you didn't tell me the code edition) means you have a Group S-1 occupancy per Table 5003.11.1. Builder Bob is basing his analysis on this mot being a S-1 or M occupancy. I am assuming a Group S-1.

If it's a S-1, you're fine. If it's not a S-1 you can increase the MAQ by 100% per footnote b in Table 5003.1.1.

If it is not a Group S-1 or M, you have a H-3.

Under the 2009

Thanks finally found the table and footnote

That should work for what they are trying to do

Trained by the HazmatPoobah. I just wish I had his Heidi Klum girlfriend and love for bourbon. God, he is a handsome, sexy man.

ok Haz per table 2703.11.1 I can have 1150

with small "g" it says I can go to 2250 BUT only if "do not exceed 10 pounds each"" ??? so does that throw out the 50 or 100 pound containers and I am back to 1150???

or does 2703.11.3.6 come into play????????

lost in the code again, dog ran away, horse died, girlfriend drove off in my pick up

 

[Builder Bob]

I am glad that somebody else jumped in..........

I do have a question - does T. 2703.1.1(3) come into play because of outdoor control area ( 2006 IFC) - (T.5003.1.1(3) 2012 IFC)

If so 40 pounds max. unless footnote a,b,c,d come into play. for an Oxidizer Class III.......

In researching CHYIS, it would seem that this material may be a high Oxidizer class II at 65% instead of a Class III Oxidizer..... 68% appears to be the breaking point from researching CHYIS

between a class II and a Class III oxidizer.

 

[Builder Bob]

Well, I did further research and read some more and would like to rescind my previous statement........ Although the previous comment has merit as far as CHYIS goes, NFPA 400 Appendix G has a specific definition concerning Class II vs. Class III oxidizer.

 

[Oldfieldguy]

See 2703.11.3.3. If the container volume is > 25 pounds, compliance with Section 2703.11 cannot be achieved. In such a case the MAQ in Table 2703.1.1(1) becomes applicable.

[cda]

Totally lost

2703.11.3.3. Deals with location

2703.11.3.5 deals with container size

Table 2703.11.1. Small "g". Says no container / package do not exceed 10 pounds

If it does I take it small. "g" or the 2,250 cannot be used

 

[cda]

Well the chemical supplier has technical help and has convinced the place they do not need the quantity on hand they were proposing.

And, will work on proper storage!!

 

[cda]

Found the problem

Should have read the book first
