Tested The oxygen level in a confined space should be at least _____ percent by volume. Occupational Safety and Health Administration. "Entry" means the action by which a person passes through an opening into a permit-required confined space . Entry includes ensuing work activities in that space and is considered to have occurred as soon as any part of the entrant's body breaks the plane of an opening into the space . Before a worker enters a confined space the internal atmosphere must be _____ . Tested The internal atmosphere in a confined space must be checked out before entering . Subpart AA of 29 CFR 1926 will help to prevent construction workers from being hurt or killed by eliminating and isolating hazards in confined spaces at construction sites. Before entry into most confined spaces a multi-gas monitor is commonly used to determine levels of oxygen carbon monoxide hydrogen sulfide ... A multi-gas detector with an internal pump (or a detector that works in tandem with a manual pump) can test the air in a confined space to determine the safety of the atmosphere before workers enter. Testing must be done in several levels of the space because specific hazardous gases react differently to the rest of the atmosphere . A confined space entry permit must be completed before work can be conducted inside the space . It is a formal check to ensure that a safe work system is in place as well as a means of communication between site management supervisors and those who carry out the work. CWA strongly believes that there must be two workers assigned to perform confined space work. This would allow one employee to perform the work inside the confined space work environment and a second employee to remain above ground/at the entrance to render assistance if a safety or health emergency occurs.
