How often should air be tested in a confined space?

To completely assess intoxicants or dangers, according to OSHA's standards, testing of the confined spaces should be performed at 4-foot intervals.

What types of ventilation can be used in confined spaces?

Forced or exhaust ventilation is suitable for confined spaces. Forced ventilation uses forced & fresh air to ventilate a confined space by displacing and diluting air, whereas exhaust ventilation uses exhaust to continuously remove contaminants at the source point.

How many air changes are required in a confined space?

According to the AIHA (American Industrial Hygiene Association), one air change every 3 minutes or 20 complete air changes per hour for a confined space is an acceptable practice. Ventilation of the confined space also depends on the product or material being ventilated from the area.

Are blowers better than fans?

Fans are electrical devices, while blowers are mechanical devices.Fans consume less electricity. Blowers relatively intake more power.Fans offer medium airflow depending on the capacity, whereas the blowers deliver better airflow than the fans.

Ventilation Kits
Air Systems International Saddle Vent ventilation systems function as a fresh air conduit to workers in confined spaces by eliminating the need for removing air ducts each time a worker needs to enter or exit. Each kit includes an air duct installed on the bottom of the Saddle Vent to supply fresh air to workers and remove harmful gases. These units come with a 90 degree elbow that permits rotation of the intake duct to the desired position.
We additionally offer vinyl constructed duct hoses having a retractable, wire-reinforced design with adjustable belt straps on both hose ends. They can handle a maximum temperature rating of 180 degrees Fahrenheit.

Electric Confined Space Fans And Blowers

Electric confined space fans and blowers circulate a continuous supply of fresh air or to push out fumes. Raptor Supplies offers a huge array of confined space blowers / fans / ventilators and jet fans from brands like Allegro, Rafman, Americ, Air Systems International and Ecko. Americ confined space blowers and air exhausters are designed for applications requiring larger amounts of air output; ideal for use in Class 1 hazardous locations like pump rooms. These intrinsically safe blowers are powered by 1.5 HP pneumatic motors capable of providing a max airflow of 2063 CFM. They are enclosed in a dual-wall shell for absorbing impact. Allegro explosion-proof, confined space axial blowers are used in closed spaces with negligible ventilation. These blowers feature powerful & energy-efficient motors capable of producing a maximum airflow of 1636 CFM at 3320 RPM. They are ideal for the removal of smoke and harmful fumes with both positive & negative ventilation and are equipped with an integrated handle for portability. Electric confined space fans and blowers also include manhole entry kits.

Working Mechanism

Select a confined or limited space that originally has toxic gases.
Generally, the tanks or any confined space is ventilated from the bottom and through an opening on the top.
Attach the vent ducts to the fans or blowers and position them on a firm footing having minimum vibrations.
Use a pull switch or simply power on to activate a ventilator.
Eliminate the concentration of the present toxic gas below the appropriate atmospheric exposure level.
