6. ACCIDENTAL RELEASE MEASURES.
These batteries are designed not to leak under normal conditions. If, however, electrolyte does leak out of any battery
for any reason, it should be absorbed onto dry sand, earth or other inert material and must not be allowed to enter any
drains. If possible, neutralise any leaked electrolyte using soda ash, sodium bicarbonate, sodium carbonate or calcium
carbonate powder and then wash thoroughly with water. Collect absorbed material and place in an inert sealed
container for disposal, see Section 13.
Exposed lead materials must be placed in an inert sealed container for disposal, see Section 13.
7. HANDLING AND STORAGE.
Store batteries in a cool and dry area with an impervious surface. Store under roof and protect against adverse
weather conditions. Protect against physical damage and exposure to organic solvents. Do not allow metal objects to
contact both terminals at the same time, as this will cause damage, may cause injury and may cause a spark, see
Section 5.
Large batteries should be handled and moved using mechanical means to prevent risk of injury.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION.
Under normal conditions, where there is no damage and no visible trace of liquid or solid deposit on the batteries, they
may be handled without any additional P.P.E. Where there are any signs of damage or liquid or solid deposits, rubber
gloves and acid resistant clothing must be worn when handling the batteries and affected packaging to protect against
the effects of any acid electrolyte that may be present. If it is suspected that free acid electrolyte is present, then safety
glasses must be worn, and if large amounts are present, chemical goggles or face shield should be used.
9. PHYSICAL AND CHEMICAL PROPERTIES.
The undamaged product is a manufactured item in an inert plastic case, which will burn if subjected to high
temperatures. Some battery types are made in flame retardent plastic, see technical Specification.
Batteries on charge may emit hydrogen gas, which is highly flammable and forms explosive mixtures in air, see
Section 5.
Electrolyte is a clear liquid with little or no smell, which contains sulphuric acid up to 40% in water in a fully charged
battery. Leaked electrolyte may dry out to form white patches or patches of other colours, usually green or brown, if
metals have been attacked, which may be acidic.
In damaged batteries, lead plates can be grey or brown, with varying amounts of white. Grey material may ignite if left
to dry out.
10. STABILITY AND REACTIVITY.
The undamaged product is stable up to 60
º
C, see Section 9.
