t 3.0 DISCUSSION f

'k 3.1 In the 125V DC system there are three separate safety related subsystems consisting of battery charger, batteries and loads. The batteries are (s / y power station type pasted plate, lead-calcium, 60 cell, rated at 2550 ampere hours (8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> discharEe rate). The ampere-hour capacity of each 125 volt DC battery is suitable for supplying all energency loads for a minimum of 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> without the use of battery chargers. .,

s 3.2 This procedure shall be performed quarterly and approximately 7 days af ter

. an equalizing charge.

If ventilation system is inoperable, area shall be checked with a portable hydrogan analyzer per Reference 11.3. No entry should be made into area where hydrogen concentration is greater than 2%.

4.2

(/)

x-There shall be no smoking, sparks or open flanes permitted in any of the battery rooms. Hydrogen released by the battery is extremely flam=able and may explode.

4.3 If electrolyte comes in contact with skin or clothing, immediately vssh with water and neutralize with a solution of baking soda and water (1 lb./ gal.). If the electrolyte comes in contact with the eyes flush with large amounts of clean water, and secure medical treatment immediately.

4.4 Promptly neutralize and recove any electrolyte spilled. Use a baking soda / water solution (I lb./ gal.).

4.5 Face shield, acid proof gloves and apron shall be worn when working with battery electrolyte.
