16. 1 Important Safety Considerations For Batteries DANGER Batteries are electrically live at all times take great care never to short circuit the battery terminals WARNING Batteries are often heavy take great care when lifting and transporting batteries For weights above 24 kilos lifting aids should be used DANGER Do NOT attempt to remove the battery lid or tamper with the internal workings of the battery Electrolyte is a highly corrosive substance and presents significant danger to yourself and to anything else it touches In case of accidental skin or eye contact flush the affected area with plenty of clean fresh water and seek immediate medical attention Valve Regulated Lead Acid VRLA batteries are low maintenance requiring no electrolyte top up or measurement of specific gravity FIRECLASS Prescient WRITTEN BY RKP CHECKED BY AP WARNING Only clean the battery case with a cloth that has been soaked or dampened with distilled water Do not use organic solvents such as petrol paint thinner benzene or mineral spirits or other materials that can substantially weaken the case Do not use a dry cloth as this will generate static electricity which in turn may lead to an explosion WARNING Avoid operating temperatures outside A the range of 15 C 5 F to 50 C 122 F for float standby applications The recommended normal operating temperature is 20 C HIGH TEMPERATURE will re
