Are all lines to a confined space, containing inert, toxic, flammable, or corrosive materials valved off and blanked or disconnected and separated before entering confined spaces?      
Are all impellersagitators, or other moving parts and equipment inside confined work spaces locked-out if they present a hazard?      
Is either natural or mechanical ventilation provided prior to confined work space entry?      
Are appropriate atmospheric tests performed to check for oxygen deficiency, toxic substances and explosive concentrations in the confined space before entry?      
Is adequate illumination provided for the work to be performed in the confined work space?        
Is the atmosphere inside the confined work space frequently tested or continuously monitored during conduct of work?      

Is there an assigned confined space attendant outside of the confined work space, when required, whose sole responsibility is to watch those working in a confined space, sound an alarm if necessary, and render assistance?

Are the confined space attendants or other employees prohibited from entering the confined work space without lifelines and respiratory equipment if there is any question as to the cause of an emergency?      
Is approved respiratory equipment required if the atmosphere inside the confined space cannot be made acceptable?      
Is all portable electrical equipment used inside confined spaces either grounded and insulated, or equipped with ground fault protection?      
Before gas welding or burning is started in a confined work space, are hoses checked for leaks, compressed gas bottles forbidden inside the confined space, torches lighted only outside of the confined area and the confined area tested for an explosive atmosphere EACH TIME before a lighted torch is to be taken into the confined space?      
If employees will be using oxygen-consuming equipment-such as salamanders, torches, and furnaces, in a confined space - is sufficient air provided to assure combustion without reducing the oxygen contrentration of the atmosphere below 19.5% by volume?      
Whenever combustion-type equipment is used in a confined space, are provisions made to ensure the exhaust gases are vented outside of the enclosure?      

This Confined Work Space checklist is NOT all-inclusive. You should add to it as necessary or skip parts that are not applicable to your company.  Carefully consider each item on this confined space checklist, and refer to OSHA inspections standards for complete and specific guidelines for safe work in confined spaces that may apply to your work environment. This confined work space list is typical for general industry, not construction or maritime.
