CYLINDER ADVICE
1. Maintenance: After each use, check for cylinder damage. Clean the cylinder and
components. If water is used to clean, make sure you allow enough time for all components
to dry. Don't reassemble until all components are thoroughly dried. Do not apply heat
higher than the temperature of steam 100°C in order to dry a wet cylinder.
2. Storage: Tightly close the cylinder valve. Leave some pressure in the cylinder (2-3
bar). Secure the cylinder and assembly from rolling, tipping over or falling. Store the
cylinder at room temperature, in a dry place, keep away from chemicals, artificial heat
sources and corrosive environments.
3. Handling: Cylinders should never be dragged, or dropped. When transporting
cylinders, make sure that the valve is well protected and that the cylinder is well secured.
4. Painting: Retouch damaged paint areas with air drying paint, but if damage has been done
to the cylinder metal or composite materials, have it visually inspected first by a manufacturer
trained service technician. Never use corrosive, caustic, or acid paint strippers, burning
techniques, or solvents, in order to remove paints from aluminum or composite surfaces.
5. Chemical Exposure: Composite materials can be attacked by chemicals or treated
water. If the cylinder has been exposed to chemicals or aggressive fluids, the external
composite surfaces must be checked for any visible signs of damage.
6. REJECT composite cylinders known to have been covered, splashed or left standing
(soaked) in unknown chemicals.
7. REJECT composite cylinders if the composite surface is blotchy or the paint
and/or resin shows signs of chemical attachment (e.g., paint or resin has softened,
smeared, bubbled, etc.).
8. HOLD composite cylinders if the composite portion has come into contact with a type
of chemical that is not listed below and if you are unsure of its effects on the composite
material. Contact Aqualung for advice.
Any cylinder composite material coming into prolonged contact with these types of
chemicals and materials must be rejected:
9. Solvents: Paint thinners, kerosene, turpentine, paint solvents, paint cleaners, epoxy
solvents, resin removers, organic solvents, etc.
10. Vehicle Fluids: Materials that contain benzene, glycol (anti-freeze), battery acids/
alkalis, window washer fluids, oils containing solvents, flammable materials, organic
volatile materials, gasoline and oil additives, fuels (gasoline, gasohol, methanol, etc).
11. Strong Bases: Materials that contain medium to high concentrations of: sodium
hydroxide, potassium or hydroxides, materials that contain strong soap solutions,
cleaning (soap) solutions, etc.
12. Acids: Materials that contain any concentration of acids like hydrochloric, sulphuric,
nitric, phosphoric, etc.
13. Corrosives: Materials that contain corrosive components or that are corrosive
themselves, such as the chemicals mentioned above and: cleaners, glass cleaners,
metal cleaners, resin cleaners/removers, drain openers/cleaners, glues, rubber and
other chemical cements, and atmospheres containing corrosive gases.
