a. Fuel Cell Precautionary /Safe / Criteria. General Information.
All regulations and instructions for handling fuels shall be strictly observed.
The following WARNINGS and CAUTIONS shall be observed before and during removal, cleaning, repair, and testing of
To prevent asphyxiation from fuel, oil and alcohol fumes, you must wear protective
clothing, i.e., an apron, an air supplied respirator, a face shield and rubber gloves. Use
an air compressor to continuously pump air into the tank when personnel are in the tank.
Ground the air hose to the tank. Assign a person to monitor the person in the tank in the
event he is overcome by fumes.
Use an explosometer to insure safe conditions in the fuel cell before starting work
Acetone, barrier cement, repair adhesives and its components are flammable and toxic.
They can irritate skin and cause bums. Use only with adequate ventilation and wear a
NIOSH approved air-purifying respirator for organic vapors. Keep away from heat or
open flame. Wear safety glasses, gloves and protective clothing to avoid contact with
skin, eyes and clothes. If contact occurs, flush areas with water and get medical
attention for eyes.
Work only in approved areas with adequate ventilation and where emergency equipment
can move freely. Initial deactivation must be done out-of-doors.
Make sure fuel cell and all cleaning, repair, and test equipment are properly grounded.
Do not enter cell unless another person is available as safety monitor.
Do not enter fuel cell wearing shoes, or with tools in your pockets.
Do not allow hot work lamps to contact fuel cell. Use only explosion proof light.
Be careful when handling fuel cell at temperatures below 20
°C) to prevent
cracking molded sections.
Do not expose fuel cell to any source of strong light for a long period.
Do not puncture or scratch lining of fuel cell. If lining is broken, fuel penetrates and
activates self-sealing layers. Activated layers swell and trap fuel. Activated green spongy
material also contaminates fuel system. This makes it necessary to replace fuel cell and
flush fuel system.
Protect fuel cell at all times from sharp objects and from extremes of temperature and
