W A R N I N G When fuel is being drained, there is little control over
the release of fuel vapor. This vapor should be dissi-
pated as quickly as possible. Compressed air or explo-
sion-proof blowers may be used for the purpose.
Air Ventilation
1 Completely drain the fuel system per Chapter 12-10-02.
2 Remove inspection doors (refer to Chapter 28-11-03) and
tank caps.
3 Use compressed air or an explosion-proof blower to blow
air into the tank until tank interior is dry and free of vapor.
4 Continue ventilation whenever tank is open and being worked
on.
W A R N I N G If flammable vapors from cleaning solvents are allowed
in the tank increase air circulation to dissipate them.
