Nesa,
Thank you for your letter dated May 6, 2011. You provided us with much useful information.

I still have a few questions that need to be answered before we can perform our risk assessment. Please 

clarify the following:

1) Background section, p. 2:

What are the approximate dimensions of the crew compartment? Is that roughly 2.0 m high x 1.5 m 

wide x 1.5 m long? And does that correspond only to the middle section with four seats, as depicted in 

Fig. 1? 

ANSWER: 

2) Alternative-Specific information, p. 3

For the classes of fires, please clarify if you mean all of the following classes:

 Class A-ordinary combustibles (paper, wood, etc)--tires mentioned by example

 Class B-flammable liquids or gases--petrol mentioned by example

 Class C-electrical fires

 Class D-metal fires--molten metal mentioned by example

 Class K-cooking oil fires

ANSWER: 

3) Installation, Maintenance, and Use p. 6

What is the rate of airflow in the spaces where the fire extinguisher be used---that is, ventilation in the 

crew compartment in cfm or in air changes per hour?

ANSWER: 

 

FYI, our risk assessment modeling will consider the settling rate [to address the condensation you 

mentioned in your response]. The modeling will also look at what proportion could still be inhaled.

Finally, please send us a copy of your letter with confidential information removed.

 
That will give us the final information we need. Thank you for your follow up and for giving us the 

information we need to complete our review.

Sincerely,

Margaret Sheppard
