You must use the form provided and follow the instructions. Just sending
a letter griping about something will be rejected out of hand. You must
propose a specific revision including the revised text. You must
reference the current (2002) document.

I have sent a proposal to alter the first line of the safe distances
table impulse limits from "160.00-320.00" N-sec to "0.00-320.00" N-sec.

The reason for this change is that some rockets/motors that have
less than 160.00 N-sec of total impulse nevertheless meet the definition
of a high power rocket/motor. This has created a situation where no
minimum safe distance has existed in NFPA 1127 for these rockets/motors.

NFPA 1122, Code for Model Rocketry, is also starting its revision cycle
but no proposal closing date is posted:
