Application Exercise
You will need
• Level A/Fully-encapsulated vapor protective ensembles (enough for each group)
• Level B/Liquid splash-protective ensembles (enough for each group)
• Hand tools
• Detection equipment (if students have received training)
• Water sources
• Departmental SOPs and inclusion criteria, if available
Preparation
This exercise is intended to give students hands-on experience donning, doffing, and wearing
different levels of chemical protective clothing. Keep the student/instructor ratio about five to
one. If necessary, enlist the assistance of another instructor while conducting this exercise. Set
up three work stations, as described below, and divide the class into three groups. Instruct the
groups to rotate through each work station until each student has performed every task at all three
stations. Complete the Exercise Assessment Sheet on the following page as you observe the
groups. Remain available to the students as they work through this exercise. Answer basic
questions but encourage them to refer to the manufacturer’s instructions as much as possible.
Reconvene the class and review the exercise and your assessment sheet. Answer any remaining
questions about CPC.
Work Stations:
• Work Station 1: Students inspect and test CPC. Guide the students through a visual inspection
of all CPC available. Have the students conduct a pressure test of Level A garments
following the specific manufacturer’s instructions. Each student must perform an inspection
and a test.
• Work Station 2: Students don and doff Level A garments. Instruct students to work one-toone.
Every student donning an ensemble should have an assistant. Have the teams don the
CPC according to manufacturer’s instructions, then have the students switch roles. Students
donning the CPC should walk to an area where they are required to perform a simple activity,
such as working with hand tools or operating detection equipment, reading a label, or writing
their name on the chalkboard. If time permits, allow the students to walk outside for a short
period of time to experience heat transfer into (or out of) the protective clothing.
• Work Station 3: Students don and doff Level B garments. Instruct students to work one-toone.
Every student donning an ensemble should have an assistant. Have the teams don the
