This Owner's Manual/Safety Procedures Guide has been prepared for the promotion of educational purposes only and

Clarke does not claim or assume any responsibility for the operator's actions or safety. To be completely aware of what

local authorities may require, contact the Fire Marshal of your community.

DANGER: It is the owner/operator's responsibility to ensure that the air-exchange system

installed in any location where a propane floor care machine is being operated is of suffi-

cient capacity and quality to support the use of such a machine. OSHA and other County,

State, or Federal Agencies publish guidelines on this subject that are usually most readily

found in the possession of the respective owners and/or parent companies of any location

or chain of locations. Failure on the part of the owner/operator to ensure that a propane

floor care machine can be operated safely in a given location may lead to injury, sickness

or even loss of life.

Engine Emissions and CO Safety

The purpose of this document is to provide information on:

· The potential effects of CO exposure;

· The methods to reduce the risk of CO poisoning;

· The methods used to determine the amount of potential exposure to CO produced by equipment.

DANGER: All LPG (Liquid Propane Gas) powered engines, including this engine, produce Carbon Monoxide

(CO). It is a LETHAL POISON that is a colorless, odorless, tasteless, and non-irritating gas. It is produced by

incomplete combustion of carbonaceous material such as propane (LPG).

Failure to provide for proper venting of CO produced during the operation of combustion powered engines may

result in SERIOUS INJURY OR DEATH to the operator and those in the contaminated area.

The effects of CO can be experienced at different exposure levels, depending on the health of the individual.

Conditions that affect the tolerance of the individual are smoking, age, temperature, humidity, and other

conditions.

WARNING: Read and understand The Operators Manual completely before using this machine

This document explains how CO produced can be managed to reduce the risk of carbon monoxide poisoning.

All distributors, owners, and operators should be aware of the potential effects of CO and the methods used to

prevent over exposure.

ALTO U.S. is dedicated to our customers, their safety, and providing information, services, and products that

meet those needs.

Information provided in this document is current as of the date written November 1997.

Document Overview

The information provided in the following overview has been condensed to provide the

reader with a summary of the material presented.

Potential Effects of CO Exposure

•Work place/industry guidelines for CO exposure limits vary substantially from region to region

(OSHA) Permissible Exposure Limit (PEL) for CO is 50 ppm, as an 8-hour time weighted average.

•Definition of CO effects - The toxic effects of carbon monoxide in the blood are the result of tissue

hypoxia (lack of oxygen). The severity depends on the state of activity of the individual and his tissue

oxygen needs.

Methods to Reduce The Risks of CO Poisoning

•Air Exchange and CO Diffusion - CO does not mix with air on its own. Air currents can “stir” the CO

and dilute the concentration values by mixing it with the available air. When using equipment over a large

area in a short time “stirring” occurs as you walk.

•Application Considerations (Burnishing versus Stripping) - When activity is concentrated to a smaller

area as in a stripping application, air “stirring” must be forced by the use of fans to reduce the risk of

high concentrations of CO.

•Air Quality Monitoring – Deployment of a monitor/detector is essential for the safe operation of any

equipment that has the potential to produce CO.

•Room Size and Time Estimations - The concentration and volume of CO production, the size of the

area and the amount of air exchange are factors involved with determining safe time limits for operation

in a specific room size.

•Maintenance of Equipment - LPG engines are dependent on engine tune up, and air filter replacement.

CO concentration (production) skyrockets when the air to fuel ratio becomes fuel rich. Follow the

recommended Maintenance Schedule for the engine.

•Safety Equipment Available. - Envirogard automated fuel to air ratio monitoring and regulation

providing an optimum combustion, three-way type catalytic converter to scrub CO, Hydro Carbons (HC),

and Nitrous Oxide (NOx) from the engine exhaust providing the lowest possible emissions, high cubic feet

per minute (CFM) fans (forced air mixing), and digital combustion analyzers for tail pipe emissions

monitoring.

Engine Emissions and CO Safety

Potential Effects of CO Exposure

· Work place/industry guidelines for CO exposure limits

· Definition of CO effects

Workplace/industry guidelinesfor COexposurelimits

Limits for permissible exposure to CO vary substantially from region to region. City, State, and Industry require-

ments should be consulted prior to use of any equipment.

The current Occupational Safety and Health Administration (OSHA) Permissible Exposure Limit (PEL) for CO is 50

ppm, as an 8-hour time weighted average (TWA). This is computed by making measurements at intervals over 8 hours,

then adding the sums of the concentrations and the intervals, and dividing by 8 hours. For example:

Time Interval PPM

8:00-9:00 1 HR 100

9:00-10:00 1 HR 25

10:00-11:00 1 HR 25

11:00-12:00 1 HR 50

12:00-1:00 1 HR 50 400ppm/8HR=50ppm TWA

1:00-2:00 1 HR 50

2:00-3:00 1 HR 50

3:00-4:00 1 HR 50

Time intervals = 8 HR ppm = 400

The current National Institute for Occupational Health and Safety (NIOSH), immediately dangerous to life and

health concentration (IDLH) recommended level for CO is 1,200 ppm. NIOSH defines the IDLH exposure level as the

concentration that could result in irreversible health effects or death, or prevent escape from the contaminated environ-

mentwithin 30minutes.

Definitionof COeffects

The toxic effects of carbon monoxide in the blood are the result of tissue hypoxia (lack of oxygen). carbon monoxide

combines with hemoglobin to form carboxyhemoglobin. Since CO and oxygen react with the same group in the hemoglo-

bin molecule, carboxyhemoglobin is incapable of carrying Oxygen. The affinity of hemoglobin for CO is 200 to 240 times

greater than for oxygen. The extent of saturation of hemoglobin with CO depends on the concentration of the gas, the

quantity of inspired air and on the time of exposure. The severity depends on the state of activity of the individual and

his tissue oxygen needs.

According to Harrison’s Principles of Internal Medicine 7th edition, no symptoms will develop at a concentration of

0.01% CO (100ppm) in inspired air, since this will not raise blood saturation above 10 %. Exposure to 0.05% (500ppm) for

1 hour during light activity will produce a blood concentration of 20% carboxyhemoglobin and result in a mild or

throbbing headache. Greater activity or longer exposure causes a blood saturation of 30 to 50 %. At this point head

ache, irritability, confusion, dizziness, visual disturbance, nausea, vomiting, and fainting can be experienced. Exposure

for one hour to concentrations of 0.1% (1000ppm) in inspired air the blood will contain 50 to 80% carboxyhemoglobin

which results in coma, convulsions, respiratory failure and death. On inhalation of high concentrations of CO, saturation

of the blood proceeds so rapidly that unconsciousness may occur suddenly without warning.

Methods to Reduce The Risks of CO Poisoning

•Air Exchange and CO Diffusion

•Application Considerations (Burnishing versus Stripping)

•Air Quality Monitoring

•Room Size and Time Estimations

•Maintenance of Equipment

•Safety Equipment Available

Air Exchange and CO Diffusion

The most reliable method to prevent CO Poisoning is to ensure all the CO produced is vented outside. With wood

stoves or gas heaters this is performed with ductwork that carries the exhaust and CO outside. Non-stationary

combustion type equipment must be used in such a way that CO is not allowed to rise to a harmful or dangerous level.

CO does not readily dissipate or mix with air on its own. Air currents can “stir” the CO and dilute the concentration

or ppm values by mixing it with the available air. When using equipment over a large area in a short time “stirring”

occurs as you walk, or to say it another way, your Effective Operating Zone is large. When activity is concentrated to a

smaller area as in a stripping application, the Effective Operating Zone is small, and “stirring” must be forced by the use

of fans to increase the Effective Operating Zone and reduce high concentrations of CO.

Air exchange rates (air exchange is defined as the exhausting of internal air to the external atmosphere), the size of

the Effective Operating Zone, amount of CO produced, level of human activity, and the duration of exposure are all

factors in the determination of the production of carboxyhemoglobin and the amount of CO blood saturation.

Application considerations (Burnishing versus Stripping)

When using equipment over a large area in a short time, as in most burnishing applications, your Effective

Operating Zone is large. When activity is concentrated to a smaller area as in stripping applications, the Effective

Operating Zone is small and stirring or CO mixing MUST be forced by the use of fans to increase the Effective

Operating Zone and reduce high concentrations of CO.

Caution: air mixing in itself may not be sufficient to reduce CO to a safe level.

The Effective Operating Zone can be defined as the area covered in a given time.

Stripping is quite a different type of operation than burnishing, and carries with it substantially more hazards, as

stripping is a low movement operation compared to burnishing (less floor space for the same time). As shown in Model

1, the CO concentrations rise much quicker as the “Effective Operating Zone” is a very small area compared to the total

building size.

Notice the CO concentration and the Effective Operating Zone with air exchange. The CO cloud is still concentrated

in a small area. Note the “Dividing Zone” shown above, this is the line where airflow changes direction. In Model 2, air

changes are cut in ½ as little or no CO crosses the Dividing Zone to be exhausted.

Notice the CO concentration and the Effective Operating Zone (Expanded to the Dividing zone) with air ex-

change and forced air mixing. The CO cloud is still concentrated on one side of the Dividing zone. Note the

“Dividing Zone” shown above, this is the line where airflow changes direction. In Model 3, air changes are cut in

½ as little or no CO crosses the Dividing Zone to be exhausted.

Notice the CO concentration and the Effective Operating Zone (Expanded through the Dividing zone to the second

vent) with air exchange and forced air mixing through the dividing Zone. The CO cloud is diluted with the available air in

the building. Note the “Dividing Zone” shown above, this is the line where airflow changes direction. In Model 4, air

changes are full as forced air mixing has moved and mixed the CO between all air zones.

AirQualityMonitoring

Warning: Deployment of a monitor/detector is essential for the safe operation of any equipment that has the

potential to produce CO. CO sensors/detectors became available on the mass market around 1978. At present several

brands sell in the fifty-dollar range. The main differences between the technologies involved are battery or electric and

Semiconductor or Biomimetic types. Detectors for carbon monoxide (CO) are manufactured and marketed for use in

either the home or occupational industrial settings. The detectors for home use are devices that will sound an alarm

before CO concentrations in the home become hazardous. There is an Underwriters Laboratories, Inc., performance

standard (UL 2034) for residential CO detectors. Detectors currently available on the market are battery-powered, plug-

in, or hard-wired. Some models incorporate a visual display of the parts per million (ppm) concentration of CO present in

the home. For more information on CO detectors for home use, call the Consumer Product Safety Commission Hotline at

1-800-638-2772.

CO detectors for use in residential settings are not designed for use in typical workplace settings. Monitoring

requirements in an occupational setting are different from monitoring requirements in the home. In the workplace, it is

frequently necessary to monitor a worker’s exposure to carbon monoxide over an entire work shift and determine the

time-weighted average (TWA) concentration of the exposure. It may also be necessary to have carbon monoxide

monitors with alarm capabilities in the workplace. The direct-reading instruments are frequently equipped with audio

and/or visual alarms and may be used for area and/or personal exposure monitoring. Some have microprocessors and

memory for storing CO concentration readings taken during the day. It is significant to note that some of the devices

mentioned for workplace CO monitoring are not capable of monitoring TWAs, and not all are equipped with alarms. The

appropriate monitor must be chosen on an application-by-application basis. For more information on the availability of

workplace CO monitors or their application, call the National Institute for Occupational Safety and Health at 1-800-35-

NIOSH(1-800-356-4674).

RoomSize andTime EstimationsforPartsPerMillion(PPM)CO

The fundamental factors in area CO levels involve:

The concentration and volume of CO production;

The size of the area;

The amount of *air exchange if any;

The amount of time CO is produced.

Multiplying length, width, and height will determine the volume or cubic feet in a room. So an empty building 100ft

by 100ft with a 10ft ceiling would be 100,000 cubic ft. in size. Any material that is in the room and takes space would

reduce the cubic feet.

*Airexchangeis defined as theexhaustingof internal air totheexternal atmosphere.
