Lesson 2/Learning Event 1
Substrate dispenser. The substrate dispenser is a plastic-coated, 1/2-oz. glass bottle capped with a
plastic nozzle. A red spot is marked on top of the cap. The nozzle is covered with a removable
plastic protective cap. The dispenser is filled with substrate solution under pressure. Carefully
depressing the top of the dispenser releases substrate solution drop-by-drop from the nozzle.
Plastic container and reagents. Inside the clear plastic container are reagents used to prepare
solutions for chemical tests. Fourteen plastic packets contain powdered reagent. These packets,
made of clear plastic, are contained in a small glass vial inside the plastic container. The stopper
and top third of the glass vial are painted green.
Instruction cards. Six plastic cards in a front pocket contain instructions for use of the kit. They are
attached to the kit by a cord.
Aspirator bulb assembly. The aspirator bulb assembly consists of a rubber bulb with a one-way
valve in its discharge end and a plastic adapter in its air intake end. The adapter is designed to hold
a detector ticket in the sampling position. A rubber tube that passes through the adapter is designed
to hold a detector tube in the sampling position. When the air intake end is closed by a detector
ticket or detector tube, compression of the bulb forces air out of the check valve. Releasing the bulb
draws air through the ticket or tube into the bulb.
Plastic squeeze bottles. Three squeeze bottles are made of translucent plastic. They are
approximately 2-5/8 inches high and are fitted with screwcaps which cover and protect removable
dropper tips. Tips can be removed from the tops of the bottles with finger pressure. Each bottle is
equipped with a colored plastic cap which matches a colored band on the bottle. The blue-marked
bottle contains a solid reagent, which must be dissolved in water before it is used. The resulting
solution is good for use until it is used up. The white-marked bottle contains buffered water
solution. The green-marked bottle is empty; it is designed to contain a reagent solution which must
be prepared fresh each day that the kit is used. In preparation of blue- and green-marked bottles,
any water fit for drinking, treated or untreated, is acceptable.
Automatic Chemical Agent Alarm
The Automatic Chemical Agent Alarm may be manpacked, mounted on selected tracked and
wheeled vehicles, or used at fixed emplacements. Detailed operating instructions are contained in
Subcourses CM 1201. Operate, Shutdown, and Service of the Automatic Chemical Agent Alarm
System; and CM 1402, Supervise Emplacement and Monitoring of the Automatic Chemical Agent
