Explanation / Answer

Failure mode Control Risk No shock due to metal cage ensure that all the power sources are properly turned off before the work starts 7 inhalation of lead Lead is a toxic metal that can enter the body by inhalation of lead dust or ingestion when touching the mouth with lead-contaminated hands.Excessive levels of lead causes brain damage, harm kidneys, impair hearing and induce behavioral problems. In adults, lead can cause memory loss and lower the ability to concentrate, as well as harm the reproductive system. Lead is also known to cause high blood pressure, nerve disorders, and muscle and joint pain. Therefore it is necessary that proper masks and gloves are worn to prevent lead exposure 8 sulphuric acid exposure The sulfuric acid in a lead acid battery is highly corrosive and is more harmful than acids used in most other battery systems. Contact with eye can cause permanent blindness; swallowing damages internal organs that can lead to death. First aid treatment calls for flushing the skin for 10–15 minutes with large amounts of water to cool the affected tissue and to prevent secondary damage. Immediately remove contaminated clothing and thoroughly wash the underlying skin. Always wear goggles and other protective equipment when handling sulfuric acid. 9 leaching of chemicals A lot of highly toxic chemicals are present in the batteries. They may leach into the ground and cause pollution. So always seal the batteries before moving them 5
