3.9 upper flammable limit (UFL): Maximum concentration of a vapor in air (or other oxidant) above which propagation of flame does not occur on contact with an ignition source. The upper flammable limit is usually expressed as a volume percentage of the vapor in air. IThis definition is based on the definitions of flammable (explosive) limits given in NFPA 325M.I

4 Administrative Controls

a. Be approved by facility management and identify who will authorize inert confined space entry.
b. Require that the entrants, entry supervisor, and rescuers be identified. (See 4.2.)
c. Provide for a written confined space entry permit.
d. Require all involved personnel to be trained in the hazards present in confined spaces with inert atmospheres.
e. Require all involved personnel o be trained in the use of proper equipment. procedures, and safeguards for their protection.
f. Establish a procedure to ensire that training for all personnel is current before the start of each job.
g. Establish the requirements for a pre-b lanning conference that involves representatives of those plant operations affected by the entry to review the written pi’ocedures. supervisory responsibilities, work to be performed.
