An ASTM F15.77 working group on magnet sets September 5 decided on potential warning language. Although the drafting wording could change based on further discussion, the consensus for now is "swallowed magnets can cause severe damage to internal organs."
Informing that choice was discussion about the understandability of terms like perforate. Also, the panel rejected F963 as an inappropriate model because as the goal of the work is to explicitly cover non-toys.
There also was rejection of the adverb accidentally modifying swallow as unnecessarily limiting and possibly confusing. The swallower's intent is less important than the act.
Relatedly, there was discussion of conveying the risks of injury and death, but there is more work to do there, possibly at the group's next session, set for September 19.
