According to Center for Disease Control and Health (CDC), carbon monoxide (CO) is a colorless, odorless, and toxic gas, which is predominately produced by incomplete combustion of carbon-containing materials. Incomplete combustion occurs when insufficient oxygen is used in the fuel (hydrocarbon) burning process – causing more carbon monoxide than carbon dioxide to be emitted.

Every year, more than 400 people unintentionally die in the U.S. from this “invisible killer,” and there are more than 20,000 emergency room visits and more than 4000 are hospitalized due to exposure to carbon monoxide.

Exposure and Symptoms

Carbon monoxide is produced by burning fuel in vehicles, furnaces, power plants, forklifts, small gasoline engines, heaters, stoves, portable generators – and the list goes on. When exposed to carbon monoxide, it impedes the blood’s ability to carry oxygen to body tissues and vital organs, depriving them the oxygen needed to function properly. Common initial exposure symptoms include headache, nausea, rapid breathing, tightness in the chest, weakness, exhaustion, dizziness, and confusion. Severe oxygen deficiency due to acute CO poisoning is called hypoxia, which may cause brain or heart damage.

You or Someone Else May Have Been Exposed to CO Poisoning?

If you believe you have been exposed to CO poisoning, or if you expect a co-worker is experiencing carbon monoxide poisoning, these actions could save lives:

• Immediately remove yourself or move the victim to an open area with fresh air
• Call 911
• If victim is breathing, use a tight-fitting mask to administer 100 percent oxygen
• If the victim has stopped breathing, administer CPR – but only if you have been properly trained to do so on victims of carbon monoxide poisoning as you may be exposed to fatal levels in a rescue attempt

Employer Steps to Prevent Carbon Monoxide Poisoning

Even though may be impossible to eliminate all risks, there are steps that can be taken to reduce the chances of CO poisoning in the workplace.

• Effective ventilation systems installed to remove CO from work areas, and the system should be maintained on a regular schedule (follow manufacturer’s instructions)
• All equipment that can produce CO should be identified as such and inspected on a regular basis as well
• Equipment powered by gasoline should be evaluated for effectiveness and never used in poorly ventilated areas – and possibly switching to equipment that is powered by compressed air, batteries, or electricity
• Employees should be educated on safe operations of the equipment and on carbon monoxide poisoning, including symptoms of CO poisoning and the appropriate steps to take if they or someone else suspects CO poisoning
• Provide employees with personal carbon monoxide monitors
• Test air frequently, especially in confined spaces
• Provide self-contained breathing apparatuses and respirators when applicable

The best way to control this workplace safety hazard is to remove it entirely from the environment. If this is not possible, taking the steps above can help protect your most important assets – your employees.

OSHA wants to hear from employers about how they’ve been using control circuit-type devices to isolate energy and about evolving technology for robotics. The information request is for a possible update of the agency’s Control of Hazardous Energy Lockout/Tagout (LOTO) standard.

Back in 1982, OSHA developed the Control of Hazardous Energy regulation to help protect workers who routinely service equipment in the workplace, and it went into effect in 1989. This regulation is now commonly known as the lockout/tagout (LOTO) regulation, and it outlines specific action and procedures for addressing and controlling hazardous energy during servicing and maintenance of machines and equipment (General Industry -29 CFR 1910.147).  The regulation also addresses a number of other OSHA standards, including but not limited to Marine Terminals, Construction, Electrical and Special Industries.

So what is hazardous energy? When machines or equipment are being prepared for service or maintenance, they often contain some form of hazardous energy, which is any type of energy that can be released and cause harm. Energy sources include electrical, mechanical, hydraulic, pneumatic, chemical, thermal and other energy sources. Failure to control such hazardous energy can cause serious injuries and death, and many injuries include electrocution, burns, crushing, cutting, lacerating, amputating or fracturing body parts.  Some examples of such injuries include the following:

• A jammed conveyor system suddenly releases and crushes a worker who is trying to release the jam.
• A valve is turned on somewhere along the same line where a worker is repairing a connection in the pipes, and the fluid or steam then spills on and burns the worker.
• Internal wiring on the equipment electrically shorts, shocking the worker repairing the equipment.

Every workplace should have an energy control program in place, with LOTO safety being part of that program. A LOTO procedure should include the following six steps:

1. Preparation – the employee must investigate and have a complete understanding of all types of hazardous energy that might need to be controlled, including identifying the specific hazards and how to control that energy

2. Shut Down – shut down the machine or equipment that will be serviced and inform any employee affected by the shutdown

3. Isolation – isolate the machine or equipment from any source of energy, which may include turning power off at a breaker or shutting a valve

4. Lockout/Tagout – the employee will attach lockout/tagout devices to each energy-isolating device – these devices should not be removed by anyone except by the person performing the lockout, and the tag should include the name of the person and other needed information who is performing the LOTO

5. Stored Energy Check – hazardous energy can be “stored” within the machine, so during this step, any potentially hazardous stored or residual energy must be released, disconnected, restrained or made non-hazardous

6. Isolation Verification – doublecheck/verify that everything was done correctly, and the machine or equipment is de-energized

It is estimated there are at least three million workers who service equipment routinely, including craft workers, electricians, machine operators and laborers. Failure to control hazardous energy accounts for nearly 10 percent of the serious accidents in many industries, and those who are injured lose an average of 24 workdays recuperating. Compliance with LOTO standards prevents on average an estimated 120 fatalities and 50,000 injuries each year.

Just about every industry has some kind of tight space that can be termed "confined" due to its size and/or shape, thereby hindering the work of anyone called upon to enter, work in, and leave it. For the purpose of rulemaking, the Occupational Safety and Health Administration refers to such an area as a "confined space."

Take a gander underneath that umbrella term, and it’s easy to see that confined spaces come in a wide variety of sizes, shapes and locations. They often present not just one but a combination of challenging conditions, such as limited movement, hazardous air and a risk of engulfment.

OSHA identifies more than 20 major sectors of industry and labor with various types of confined spaces. Such spaces include:
-Tanks
-Vessels
-Silos
-Storage bins
-Hoppers
-Vaults
-Pits
-Manholes
-Tunnels
-Equipment housings
-Ductwork
-Pipelines

Just because some confined spaces aren't necessarily designed for easy access doesn’t necessarily mean workers are not expected to enter them, periodically or routinely, in order to perform their jobs. Keeping a work site safe, in and around such conditions, means having correct and up-to-date information about each confined space.

Part of that process involves having a comprehensive plan to address the uncertainties of rescue in confined spaces. That means providing the proper training and equipment so personnel can perform the assigned rescue task for a safe and effective rescue.

A robust confined space safety program should focus on a central goal: protecting workers' safety and health. A written program should include the practices used to remove or control hazards and to ensure safe operations. In addition to preventative measures, the program should discuss air quality monitoring, exit and entry methods, and fall protection/rescue systems.

At Workplace Health & Safety Co., we can help with all those aspects and more. So if you find yourself with questions about confined spaces, reach out to us. We can help in a tight spot.
