DUST WARNING
Cutting, especially when DRY cutting, generates dust that comes from the material being cut, which frequently contains silica. When dry cutting, be sure to use a HEPA filtered dust collector. Silica is a basic component of sand, quartz, brick clay, granite and numerous other minerals and rocks. Exposure to excessive amount of such dust can cause: n Respiratory diseases (affecting your ability to breath), including chron-
ic bronchitis, silicosis and pulmonary fibrosis from exposure to silica. These diseases may be fatal; n Skin irritation and rash; and n Cancer according to NTP and IARC
*National Toxicology Program, International Agency for Research on Cancer
Take precautionary steps n Avoid inhalation of and skin contact with dust, mist and fumes; n Wet cut when feasible, to minimize dust; n Wear and ensure that all bystanders wear appropriate respiratory
protection such as dust masks designed to filter out microscopic particles. (See OSHA 29 CFR Part 1910.1200)
CARBON MONOXIDE WARNING
OPERATING ENVIRONMENT The DiamaPro® DX22-P can be operated outdoors within the temperature range of 41°F to 86°F (5°C to 30°C). It’s crucial to avoid using the machine during rainy or snowy weather conditions. When using the machine indoors, make sure to work in areas that are adequately ventilated.
PROTECTION DEVICES The machine is equipped with multiple safety mechanisms, including: a protective skirt and a hood that shield the tool plates. These contrivances safeguard the operator and any other individuals from potential harm. It is imperative not to remove them. Instead, prior to utilizing the machinery, ensure that all safety devices are appropriately installed and operational.
USAGE SAFETY The DiamaPro® Systems DX22-P is intended to minimize all associated hazards related to its operation. Nonetheless, it is not entirely feasible to eliminate the possibility of accidents with the machine. Inexperienced or untrained operators may cause residual risks associated with: n Positional hazards due to improper operator posture n Entanglement hazards arising from the use of unsuitable work attire n Training hazards caused by insufficient operational training
SAFETY MEASURES FOR PROPANE Propane is a flammable gas with vapors that are denser than air. Similar to gasoline, improper handling of propane can lead to explosions. To aid in detecting leaks, propane is mixed with an odorant that has a distinctive smell, detectable at low concentrations. When working with propane, it is essential to be aware and take necessary safety precautions. As long as these measures are observed, the risk is minimal. However, lack of awareness could result in needless hazards. The two most significant dangers associated with propane-powered floor care machines are: n Carbon Monoxide Poisoning:
Carbon monoxide poisoning is the most commonly reported incident associated with propane-powered floor care machines, caused by excessive exhaust emissions. The symptoms include headaches, dizziness, and nausea. Engines with inadequate preventive maintenance practices, particularly those with unclean air filters and machines operated in enclosed spaces without sufficient ventilation, are a significant cause. The use of substandard, inexpensive machines without emissions control technology and improperly adjusted carburetion could also contribute to the problem. n Overfilled Fuel Cylinders: Almost all fire-related incidents reported occur when a cylinder is brought into a building without first checking for overfill. This practice is hazardous, imprudent, and avoidable.
SAFETY AGAINST FIRE Be mindful of the potential risks of fire or explosion when working with propane and take standard fire-safety measures. n Fire:
There is a likelihood of fire resulting from leakage or venting of LPG vapor from fuel cylinders or carburetion equipment. n Explosion: Concentration or confinement of LPG vapor in a restricted or small space may cause ignition or explosion. Propane may also experience a BLEVE: Boiling Liquid Expanding Vapor Explosion.
EMISSIONS All propane-powered floor care machines generate emissions. While most are innocuous, some can be hazardous, even fatal. Carbon monoxide (CO) presents the most significant danger since exposure to CO at a concentration of 3,000 parts per million (ppm) for as little as 30 minutes can be lethal. Carbon monoxide is a colorless, odorless, and invisible gas formed when fossil fuels, including propane, gasoline, wood, coal, oil, and methane, burn incompletely.

AGENCIES AND REGULATIONS n National Fire Protection Agency (NFPA)
To operate a propane-powered floor care machine safely, it is necessary to adhere to specific safety regulations. The NFPA is responsible for ensuring safe propane use and storage, and their Standard for Storage and Handling of LP Gas should be consulted for guidance. Copies of this publication can be obtained by contacting the NPFA in Quincy, MA at 1-800-334-3555. One important regulation set forth by the NFPA #58 is that all personnel who handle propane gas must be properly trained in its safe handling and operation procedures and carry a certification from their employer or training supervisor attesting to this fact. While this requirement primarily applies to individuals who fill and transport liquid propane gas, DiamaPro® Systems recommends that operators of propane-powered floor care machines in public areas also receive proper training and certification. Although NFPA 58 8-4.5 permits the use of propane- powered floor care equipment in buildings frequented by the public, including when they are occupied, DiamaPro® Systems suggests that these machines be used when occupancy is minimal. n California Air Resource Board (CARB) & Environmental Protection Agency (EPA) While CARB and EPA establish limits for propane-powered engines used outdoors, it is important to note that approval from CARB/EPA does not indicate that the engine is safe for indoor use. n Canadian Gas Association (CGA) A limit of 1500 ppm CO in exhaust flow has been established by the CGA. n Occupational Health and Safety Administration (OSHA) When it comes to propane-powered machines utilized indoors, OSHA has implemented an 8-hour time-weighted average (TWA) limit of 50 ppm CO in ambient air. OSHA is also contemplating the establishment of a limit of 800 ppm CO in exhaust flow. n Department of Transportation (DOT) Regulations have been set forth by the DOT regarding the safety of fuel cylinders, including those utilized on propane-powered floor care machines. n Local Agencies Before granting approval for the use of certain equipment, local law enforcement agencies such as the Fire Marshall may rely on independent testing laboratories like UL and CGA. These labs conduct extensive testing of equipment and only issue their approval after a rigorous evaluation process. While not mandatory for all law enforcement agencies, the stamp of approval from these organizations serves as an additional assurance for operators that they are working with and around safe equipment.
PERSONAL PROTECTIVE EQUIPMENT When operating the machine, it is important to: n Wear safety shoes at all times. n Wear ear protectors to safeguard your hearing. n Ensure that all personnel in the immediate work area wear safety
glasses with side shields. n Wear safety gloves when changing tools. n Dress appropriately for the work environment. n Use Carbon Monoxide monitors.
TESTING: Numerous tools are available in the market for detecting toxic gases. However, only the ones specifically designed for detecting carbon monoxide resulting from combustion engines are deemed suitable for testing exhaust emissions from floor machines powered by propane. Certain instruments are meant for detecting “ambient air” and may get damaged if utilized for taking readings in the muffler or tailpipe. Hence, it is crucial to select the appropriate instrument to fulfill the testing requirements. In general, instruments that can detect readings in ppm (parts per million) ranging from 0 to 1000 are sufficient for examining ambient air, i.e., the air in the breathing zone of the operator. On the other hand, devices capable of testing carbon monoxide in the exhaust should be certified by the manufacturer for that purpose and should be able to read from 0 to at
least 2000 ppm.
Several instruments and systems for these purposes include:
1. AMBIENT AIR MONITORING n DRAGER Model 190 manufactured by National Drager n SENSIDYNE gas sampling system with YB-11038 Sensidyne detector tubes n DRAGER gas sampling system with YB-4620 Drager detective tubes n GAS-TECH Model CO-95 n ENERAC POCKET 60 manufactured by Energy Efficiency System
2. ENGINE EXHAUST ANALYZERS n HORIBA GAS ANALYZER n ENERAC 2000 COMBUSTION ANALYZER n ENERAC POCKET 60
3. DATA LOGGERS n INDUSTRIAL SCIENTIFIC CORP. MODEL STX-70 CO MONITOR, Data- Logger n BIOSYSTEMS INC. “TEXILOG” Data-Logger
All instruments used for testing must be calibrated at the intervals recommended
by the manufacturer. The test results must include the monitor’s model number and
date of calibration.
