APPENDIX: SUGGESTED GUIDELINES FOR
PROPANE POWERED FLOOR CARE MACHINES
SAFETY IAQ (INDOOR AIR QUALITY)
1. Propane powered floor care machines are not to be operated in any
buildings unless the air conditioning/heating ventilation system is in operation.
2. Carbon monoxide readings of ambient air (at the operator’s breathing
level) while operating the propane powered floor care machine will be taken
once each month and recorded on a logbook provided by the building/store
manager. Each test session shall be no less than 60 seconds in length and
shall be done while operating the propane powered floor care machine during
a routine work period.
3. Periodic, unannounced tests of ambient air should be made by the building
management with a “Data-Logger” designed to read and log the carbon
monoxide in ppm (parts per million) at 1 (one) minute intervals with a range of
0 to 1000 ppm. Each test session shall be no less than 15 minutes ini length
and shall be done while operating the propane powered floor care machine
during a routine work period. Air sampling should be done in the “breathing
range” of the operator.
4. If find any readings of ambient air carbon monoxide greater than 24 ppm at
any time it will be necessary to discontinue the use of the propane powered
floor care machine until it has been properly serviced and certified as
complying with the guidelines.
TESTING EQUIPMENT REQUIREMENTS
There is a great number of instruments offered on the market to test for toxic
gases. Only those designed to read carbon monoxide resulting from
combustion of propane gas in an internal combustion engine are considered
acceptable for testing exhaust emissions from propane powered floor care
machines.
Some instruments are used to read “ambient air” and may be damaged if
used to take readings in the muffler or tail pipe. Selecting the proper
instrument is an important part of meeting the testing requirements.
