(1) Warning notice. It is recommended that a warning notice be posed near the battery installa­tion as shown in table 14-1. Use the first parenthe­sis as applicable to the electrolyte type. Fill in the fault current amperes.

(2) Warning sign. It is recommended that a warning sign be posted in advance of the installed table 14-1 warning notice. Figure 14-1 is a warning sign used by a manufacturer who provides small sealed, low-gassing type batteries. Note that this warning sign indicates DANGER even for what is represented as a small sealed-battery system. Par­ticular attention must be given to the prevention of sparks or flames near batteries. The hydrogen gas produced by charging batteries is flammable in an atmosphere where the gas content exceeds 4 per­cent hydrogen gas. If the mixture contains more than 8 percent hydrogen, it can explode.

b. Electrolyte hazard. Battery rooms are required by OSHA to provide emergency-use quick-drenching facilities for the eyes and body within 25 feet of the work area. Permanent emergency eyewash and showers are recommended. Portable emergency eye­wash and showers must be brought into the main­tenance area if permanent facilities are not pro­vided.
