(2) M9 chemical detector paper (figure 1-8) is used to detect the presence
of liquid chemical agents. It does not detect chemical agent vapor. When the paper
turns red or reddish color, it indicates the presence of a nerve agent (G and V) or a
blister agent (H and L). M9 paper should be read only with a source of white light.

b. M256-Series Chemical Agent Detector Kit. The M256-series chemical
agent detector kit (figure 1-9) is issued to squads, crews, or sections. The kit provides
the squad level ability to detect and identify field concentrations of nerve, blister, or
blood agent vapors. The kit can differentiate between classes of agents which helps
unit leaders determine when unmasking may be safe after a chemical attack. The
M256 consists of 12 individually packed samplers/detectors, a set of instruction cards,
and a packet of ABC-M8 VGH chemical detector paper.
