Ductwork Installation and Maintenance Safety
Ductwork Installation and Maintenance is a routine task for most HVAC employees, who often face the same hazards as construction workers, but receive significantly less training than the latter. Over the years, this has led to a series of preventable injuries that have drawn attention to the HVAC sector and have ultimately compelled businesses to implement rigorous safety courses for their employees.
The most common risks associated with ductwork installation and maintenance are:
Accidental FallsHVAC employees are frequently required to use aerial lifts and work at heights, but many of them are not properly trained to manage fall arrest systems. As such, the majority of injuries occur when workers slip and fall, either on the same level or for several feet. These accidents can prove to be fatal, which is why it is essential for all HVAC employees to receive proper training in fall arrest.
Lack of Oxygen in Confined SpacesHVAC employees are sometimes required to enter ductwork for maintenance and repair. Inside these confined spaces, they must deal with a potentially hazardous atmosphere, as well as excessive heat and lack of proper oxygenation. Some ductwork – such as boiler ductwork, for example – may even contain unguarded machinery that can result in serious injury.
ElectrocutionDuctwork systems are generally installed in the proximity of electrical wiring, which may or may not be properly isolated. During ductwork installation and maintenance, employees might come in contact with electricity and may suffer from electrocution if they are not equipped with the correct personal protection gear.
Injury from Lifting Heavy MaterialsAlthough HVAC employees can use aerial lifts to reach the necessary height for ductwork installation, they are still required to manually raise and carry heavy materials that can cause injuries to muscles, as well as ligaments, nerves, and discs of the lower back. Such traumas are especially likely to occur due to repeated movements over the course of the day.
The first step towards incident prevention in the HVAC sector is a more rigorous focus on safety training for all employees. In addition, there are a number of measures that can be implemented in order to avoid or mitigate hazardous situations.
For example, using the correct personal protective equipment can significantly reduce the number of injuries caused by same-level falls. Furthermore, when employees are required to work at heights, they must be able to choose the right gear for the task, as well as assess any potential fall hazards and immediately implement fall arrest strategies in case of an emergency.
Although working in confined space is, at this time, unavoidable in the HVAC sector, industrial ductwork can be fabricated in such a manner as to allow for easier and safer access. In addition, employees can be provided with non-cumbersome access equipment, as well as respirators when they are likely to encounter a hazardous atmosphere. To alleviate the strain on workers’ bodies during ductwork installation, vacuum and duct lifts can be implemented.
Safety Courses Recommended for Ductwork Installation and Maintenance
This online Confined Space safety training course has been developed and updated in accordance with Standard CSA Z1006-16 - "Management Of Work In Confined Spaces" and was created to help workers become aware of the hazards associated with confined space jobs. Depending on your duties, additional workplace specific hands-on practice and evaluation may be required, as described in the course content.
Aerial Lifts Safety
HVAC staff are frequently required to use aerial lifts in order to reach the necessary height for ductwork installation and maintenance. Where this is the case, employees must be prepared to inspect a boom supported platform for safety purposes, as well as operate it correctly and take the necessary safety precautions when working around it.
Fall Arrest Training
Accidental falls cause the majority of injuries in the HVAC sector, which is why all employees working at height during ductwork installation and maintenance must receive proper training in fall arrest systems. An additional course in Fall Awareness can further decrease the likelihood of same-level falls.
Confined Space Training
Industrial ductwork constitutes a particularly dangerous confined space. Workers are not only required to deal with limited means of entry and exit, but may also have to deal with extreme heat, contaminated atmospheres, or lack of proper oxygenation. Rigorous training in Confined Spaces safety considerably increases the chance that these crises are resolved successfully.
What You Can Do to Stay Safe
To ensure your safety and that of your colleagues in the HVAC sector, you must assume a pro-active stance in preventing and combating the hazards typically associated with your work environment. The best way to do so is to undergo the required safety training programs that are provided to you by your employer.
