Badge-Type Ambient Ozone Monitor
Shall measure the level of ozone present in the 1.
room where ozone equipment is located.
The ChromAir® System ozone badge
2.
(K&M Environmental P/N 380010-10; www.
kandmenvironmental.com; 1-800-808-2234)
may be used for personnel or area monitoring
for exposure times ranging from 5 minutes to
10 hours. For higher resolution, the ChromAir
ozone badge may be used in conjunction with
the ChromAir ozone color comparator.
ChromAir System features: a.
• Constantly monitors work environment
• Accurate measurements
• Ease of use - requires minimal training
• Cost effective - offers the most
inexpensive air sampling solution
available
ChromAir System specifications: b.
• Color change: blue to white
• Exposure range: 0.08–1.6 ppm•hr
• Max. sampling time: 10 hours
• Min. sampling time: 5 minutes
• Relative humidity range: 20% - 90%
• Face velocity range: 10-165 cm/sec
• Temp. range: 16°C - 30°C (61°F - 86°F)
• Light effect - sunlight: not recommended
• Light effect - visible: no effect
• Dimensions: 10.5 cm x 5.5 cm x 0.25 cm
• Weight: 11 g
• Refrigerated shelf life: 1 year
Other ambient ozone monitors are also available.

OZONE IN WATER
The ozone concentration in water can be measured
in different ways.
Oxidation Reduction Potential (ORP) monitor 1.
measures the effective biocidal activity of
dissolved ozone in water in millivolts and can
be converted to mg/l (ppm).
NOTE: ORP
is an ineffective measurement of ozone
concentrations greater than about 0.5 ppm.
Dissolved Ozone monitors measure levels 2.
of dissolved ozone in water (mg/l or ppm).
The HACH Indigo Blue AccuVac high range
dissolved ozone test kit (DEL P/N 6-0116) is an
inexpensive colorimetric test. Electronic, in-line
dissolved ozone monitors are also available.
Contact DEL for further information.
7E-3. Ozone Detection Data Log
In addition to automatic chart recorders, operators
should log ozone monitor output. Record ozone
output data twice per shift (maximum 12 hour
shift). If system does not have an automatic chart
recorder, record data every 4 hours, regardless of
shift changes. (See Daily Data Log - Appendix A).
7F. First Aid Procedures
7F-1. General
First Action:
DO NOT PANIC. 1.
If exposure to gaseous ozone causes 2.
headaches or shortness of breath, immediately
remove the patient to a fresh air environment.
