just answer case study 2

CASE STUDY 1 FIREFIGHTERS AND CANCER Sabrina is a firefighter for her town's fire service and she has seen a significant dif. ference in the way houses and buildings are burning due to the use of new building materials that are not only lighter but also treated with chemicals designed to resist mould and insects. Furthermore, the new furniture in many homes and buildings is now made of lighter and manufactured materials that create a very acrid and toxic smoke when burned. Sabrina and her colleagues have been reading and research ing that the incidence and types of cancers afflicting career firefighters is increasing dramatically. Sabrina and her colleagues have raised their concerns to their chief who has contacted you for help in responding to their concerns. As a health and safety professional, how would you handle this situation? What would you do to ensure your town's firefighters feel educated and protected from the new chemical hazards they are being exposed to? CASE STUDY 2 UNEXPECTED GAS A man was killed by an explosion when another worker attempted to cut through the top of one of two old steel drums using a handheld grinder . Both barrels had contained a fruit concentrate but were never cleaned. The sparks generated by the grinder ignited hydrogen gas that had been generated from the contents' residue after standing for many years. Because there was a defective sterile coating separat- ing the walls of the drum from the concentrate, the acid in the fruit concentrate reacted with the metal of the drum and formed hydrogen gas. The gas accumulated and the pressure caused the drum ends to bulge. This deformation made it impos- sible to open the drum with the drum opener, and a hole was punched into the top of each drum. One worker was attempting to add water to one drum in order to displace the remaining gas, while another worker attempted to open the other drum with a grinder. Sparks ignited the hydrogen gas, causing an explosion and a fire. The fire was extinguished, but one worker lost his life. The defective drums had been recalled years before by the supplier, and only three remained unac corinted for before the accident. What steps would you take to ensure that this event was never repeated
