Hey! The answers (if the question requires two answers) is chemical spills and fires. Of only one answer is required then fires.
Reason for first answer (chemical spills and fires) it mentions that Kyle makes sure that "the storage of chemicals--" are all correct, having that being said he makes sure that there are no chemical spills. The reason for fire is becuase it mention that he makes sure the oxygen tanks are properly stored. Well certain chemicals (when mixed with oxygen) can cuase a fire, therefore fire is a good answer for rather it's a two options answer or just one. Hope this helps!
