Any space that is largely enclosed not always entirely including chambers, vessels, tanks, silos, pits, etc. is referred to as a confined space.
Confined spaces carry a foreseeable, specified risk of serious injury. Anyone entering a confined space must recognize the possible dangers, carry protective equipment necessary to ensure safety, and have proper safety training.
No matter how accustomed an employees may be with a confined space, there will always be risks and the hazards in a confined space can be very deadly, but with careful planning, the right equipment and thorough training, the hazards inside a confined space can be controlled.
Confined Space Equipment Buying Guide
Statistics from OSHA show that at least 60 people die each year from improper ventilation in confined spaces.
At least 6,000 sustain injuries. These numbers can drastically reduce if companies invested in the right confined space air blowers and other key equipment including a tripod for confined space as well as the confined space tripod kit.
Here are some of the factors to consider when shopping for a confined space ventilation system.
Budget. The price for confined space equipment is a key factor when it comes to the purchase of these items. Remember cheap may be expensive in the long run. Budget wisely.
Power sources. Confined space air blowers can be gasoline, pneumatic, or electric-powered. The ones powered by electricity are in both AC and DC options. Power options are limited in confined spaces.
Size and dimensions. Confined spaces are tiny. You don’t want to purchase a ventilation system that’s too big for the space you intend to ventilate. Also, make sure that the space correlates with the length of the duct.
Hazardous or non-hazardous. Confined spaces can be hazardous — potential to cause an explosion. Some blowers are not designed to operate in combustible spaces unless they are explicitly marked so.
