To help clear the air, here is some advice for selecting a proper ventilation blower for a confined space, as well as some tips on usage.
For all of the attention that confined spaces receive, many safety managers are still uncertain about ventilation requirements. They may not understand how much airflow is needed to properly ventilate a given space. They may overlook ventilation principles allowing them to eliminate pockets of bad air or dead spots where workers are positioned, or they may fail to monitor air quality before and during employee entry into a confined space. To help clear the air on this subject, here is some advice for selecting a proper ventilation blower for a confined space, as well as some tips on proper usage. Direct Drive
First, it is necessary to understand what defines a confined space. A confined space is not designed for continuous worker occupancy but is large enough for a worker to be able to enter and perform work. It also has limited or restricted means for entry or exit. Common examples of confined spaces include tanks, vessels, silos, storage bins, hoppers, vaults, pits, manholes, tunnels, equipment housings, ductwork and pipelines.
A confined space may have natural ventilation, but it may not be sufficient enough to provide the proper working atmosphere. A confined space may have no ventilation at all. In both instances, forced air ventilation may be required. A confined space also isn’t necessarily small; on the contrary, it can be quite large. Several factors may contribute to defining a space as confined, so having a thorough understanding of OSHA regulations is the best way to determine if a particular space qualifies.
A confined space will be one of two types: hazardous or non-hazardous. Any area where the possibility of fire or explosion may exist due to the presence of flammable material is what the National Electrical Code (NEC) defines as a hazardous location. It can also be deemed hazardous if the confined space atmosphere contains toxic or hazardous substances that can create an oxygen deficiency or harm a worker as defined by OSHA standards. Sites such as petrochemical plants, fuel-servicing facilities, industrial processing centers, grain elevators and sewers are all examples of hazardous locations. Any confined space that contains serious safety or health hazards requires a permit, which documents the atmospheric conditions of the space. Permits can also be used to help determine the right type of blower needed for the job.

The MGC Simple Plus is a simple-to-use, portable multi-gas detector that runs continuously for three years without needing to be recharged or routinely calibrated after its initial charge and calibration during manufacturing. The detector reliably tests a worksite’s atmosphere for hydrogen sulfide, carbon monoxide, oxygen and combustible gases (LEL). Additionally, it is durable enough to withstand the harshest treatment and environments, which is why it has an IP 68 rating. The MGC Simple Plus is also compatible with a variety of accessories, such as Gas Clip Technologies’ new GCT External Pump. Visit gascliptech.com for more information. 3
