Hello
Volatile chemicals like formic and thymol can be much more hazardous to the
operator than an organo-phosphate like coumaphos. The LD50 attempts to rate
all substances on the toxicity if ingested. This is a gross
oversimplification at best. No one would be likely to ingest a Checkmite
strip, but one could easily inhale fumes from formic or thymol. I have
handled all these substances and I regard Checkmite as very safe to the
operator (provided nitrile gloves are worn). The others, as well as the old
demon Phenol, are risky and should be used with caution and plenty of fresh
air.
