@roger,
maybe its a generator of methane or amines that can spontaneously explode.
Also,i f the damn thing was made in China or somehwere else in Asia, they have a major misunderstanding of many of our words (such as explosion).
Ive often read some instruction manuals of a particular piece of electronics where the admonitions to safety are a little over the top. reember they probably used some ESL who doesnt really have a grasp of the fact that idiomatic phrases are incorporated within our speech
