How can employers help prevent CO poisoning?
To reduce the chances of CO poisoning in your workplace:
• Install an effective ventilation system that will remove CO from work areas.
• Maintain equipment and appliances that can produce CO to ensure they are in good
working order, promote their safe operation, and reduce CO formation.
• Consider switching from gasoline-powered equipment to equipment powered by
electricity, batteries, or compressed air if it can be used safely.
• Prohibit the use of gasoline-powered engines or tools in poorly ventilated areas.
• Provide personal CO monitors with audible alarms if potential exposure to CO exists.
• Test air regularly in areas where CO may be present, including confined spaces.
• Install CO monitors with audible alarms.
• Use a full-face piece, pressure-demand, Self-Contained Breathing Apparatus (SCBA)
certified by the National Institute for Occupational Safety and Health (NIOSH) or a
combination full-face piece, pressure demand supplied-air respirator with auxiliary self-
contained air supply in areas with high CO concentrations (those immediately dangerous to
life and health atmospheres).
• Use respirators with appropriate canisters for short periods under certain circumstances
where CO levels are not exceedingly high.
• Educate workers about the sources and conditions that may result in CO poisoning as well
as the symptoms and control of CO exposure.
• In addition, if your employees are working in confined spaces where the presence of CO is
suspected, you must ensure that workers test for oxygen sufficiency before entering.
What can employees do to help prevent CO poisoning?
To reduce the chances of CO poisoning in the workplace, employees should:
• Report any situation to your employer that might cause CO to accumulate.
• Be alert to ventilation problems—especially in enclosed areas where gases of burning fuels
may be released.
• Report promptly complaints of dizziness, drowsiness, or nausea.
• Avoid overexertion if you suspect CO poisoning, and leave the contaminated area.
• Tell your doctor that you may have been exposed to CO if you get sick.
• Avoid the use of gas-powered engines, such as those in powered washers as well as heaters
and forklifts, while working in enclosed spaces.
What are the OSHA standards for CO exposure?
The OSHA PEL is 50 parts per million (ppm). OSHA standards prohibit worker exposure to more
than 50 parts of the gas per million parts of air averaged during an 8-hour time period.
