11.3.3. Medical Evidence. Applicant is physically qualified to perform tank cleaning.
11.4. Tank Entry Personnel Requirements.
11.4.1. Medical Requirements. Prior to entry and or cleaning operations, each tank entrant (military
or civilian) must have proof of a current physical (AF Form 600, Treatment Record, or equivalent),
or an appropriate medical statement from the local medical facility stating the applicant is physically
qualified to perform tank cleaning. Medical statements are valid for one year. Provide an AF Form
2772, Certificate of Respirator Fit Test, or equivalent showing the individual has been fit-tested to
wear a respirator.
11.4.2. Health Effects. Colds, fatigue, overheating, or lowered physical resistance from any source
increases a person's susceptibility to hazards encountered in tank entry.
11.4.3. Psychological Effects. Anyone with a medically documented history of claustrophobia will
be disqualified from entering any tanks.
11.5. Confined Space Entry Requirements. AFOSH Std 91-25 contains requirements for practices
and procedures that provide protection for Air Force employees (military and civilian) who enter and
work within confined spaces. Information in AFOSH Std 91-25 is considered the Air Force's minimum
safety, fire prevention, and occupational health requirements.
11.6. Tank Cleaning Crew.
11.6.1. Crew Members. The typical crew size for tank entry is five: TES; entrant; attendant;
regulator monitor (duties may be performed by the attendant if conditions allow); and organizational
rescue team (standby rescue personnel). Additionally, a pump or compressor operator may be
required. Individuals assigned these duties will not leave their positions until relieved by the TES.
Any deviation from the above must be coordinated with the MAJCOM fuels engineer.
11.6.2. TES. The TES, also referred to as the entry (on-site) supervisor, is responsible for all aspects
of tank entry and stays at the job site until all individuals have exited the tank. The TES only
transfers supervisory responsibility when he or she enters the tank. Before entry, the TES appoints an
equally qualified individual to run operations while he or she is in the tank.
11.6.2.1. The TES ensures all workers are properly trained on safe tank entry procedures, use of
protective equipment, and ways to egress the confined space.
11.6.2.2. The TES must review as-built drawings to become familiarized with tank components
and appurtenances.
11.6.2.3. Before starting any tank entry project, the TES briefs all members of the tank entry crew.
The briefing includes: duties of each member; hazards affecting the entry; component inspection
requirements; worker actions if there is an emergency; length of time each person will be in the
tank; effects of inhalation; other health and safety aspects inherent to the entry.
11.6.2.4.
The TES must follow the confined space entry procedures outlined in
AFOSH Std 91-25, Paragraph 2.13. For additional information, use the planning checklist in
AFOSH Std 91-25, Appendix E, as a guide to develop a site-specific work plan.
