Carbon monoxide (CO) is a colorless, odorless, and toxic gas emitted by gas-powered devices including automobile and forklift internal combustion engines. Due to its colorless and odorless nature, CO is difficult to detect and can have negative effects in different concentrations. As CO is a main output of forklift engines powered by LPG, your operators’ exposure to the gas should be limited and monitored.
CO Poisoning and its Effects
In low concentrations CO can cause noted fatigue in healthy people or chest pain in those suffering from heart disease. If your warehouse facility is improperly ventilated, your operators can quickly grow fatigued from CO exposure, putting your workers at risk of injury and undermining your operation’s productivity.
As concentrations of CO rise, exposed people can experience:
- impaired vision
- reduced brain function
- poor coordination
CO is fatal at high concentrations as it binds to blood cells before they can be oxygenated, depriving the brain of needed oxygen. These negative effects are known as carbon monoxide poisoning.
If detected early, carbon monoxide poisoning can be reversed. However, there is still a risk of permanent damage due to the oxygen deprivation associated with the symptoms.
In order to limit CO exposure and maintain safe working conditions in your facilities you must combat two common contributors to high CO levels:
Regulations and Reporting
- Equipment: Older and out-of-tune IC forklifts can produce increased levels of CO. If you believe that your equipment is contributing to CO exposure for your operators, the forklift in question should be pulled for testing and engine tuning. Newer forklifts meet more stringent environmental requirements and have lower CO output than older models. If CO is an issue it may be time to update your forklift fleet.
- Facilities: Proper ventilation and air exchange are crucial for maintaining a healthy mix of air that meets or exceeds regulations. It can be difficult to maintain this necessary mix during the winter seasons when you close doors and try to limit energy expenses. Maintaining proper ventilation, air exchanges between your warehouse and separated offices, and regular testing and monitoring can help prevent issues from arising.
In addition to the costs of lost productivity and worker care, carbon monoxide poisoning can prove costly for your business. If an employee is hospitalized due to CO exposure, staff are required to report the incident. Your facility would then fall under a safety audit including air quality samples that could be subject to a citation and fine, as well as a required compliance plan for quickly rectifying the issue.
To limit CO exposure and keep your facilities safe for operators’ health and productivity:
- Ensure proper ventilation and air mixing, even in winter months
- Complete regular maintenance and tuning of your forklift fleet
- Forklifts should be tested to ensure their exhaust output is within prescribed averages
- Consider replacing older, outdated LPG models with newer forklifts
- Test air quality regularly to ensure safety
