Confined space atmospheric test
OSHA mandates that all confine spaces be tested and ascertain safe before being inhabited. Also the confine space should be continuously monitored as far as the confine space is still inhabited.
OSHA standard 29 CFR 1910.146 (c) subsection (C) states: Before an employee enters the space, the internal atmosphere shall be tested, with a calibrated direct-reading instrument, for the following conditions in the order given: (1) oxygen content, (2) flammable gases and vapors, and (3) potential toxic air contaminants.
Additionally, subsection (D) states: There may be no hazardous atmosphere within the space whenever any employee is inside the space.
This standard shows the need for using a multi-gas monitor to perform atmospheric testing prior to entering a confined space.
If hazards are found in the space through utilization of a multi-gas monitor, OSHA standard 29 CFR 1910.146 (c) subsection (E) must be followed. This standard reads: Continuous forced air ventilation shall be used, as follows: (1) An employee may not enter the space until the forced air ventilation has eliminated any hazardous atmosphere; (2) The forced air ventilation shall be so directed as to ventilate the immediate areas where an employee will be present within the space and shall continue until all employees have left the space; (3) The air supply for the forced air ventilation shall be from a clean source and may not increase the hazards of the space.
