Who is responsible for creating JSAs? Although Supervisors and Safety Professionals generally develop the JSAs, the forms shall be reviewed by workers performing the job for feedback and suggestions. Often times, employees who routinely utilize equipment and/or perform specific job tasks are better able to identify certain hazards associated with the work, so it is critical that those individuals be involved in the JSA development process.

LiAlH 4 contains wt% hydrogen, thereby making LAH a potential hydrogen storage medium for future fuel cell -powered vehicles . The high hydrogen content, as well as the discovery of reversible hydrogen storage in Ti-doped NaAlH 4 , [36] have sparked renewed research into LiAlH 4 during the last decade. A substantial research effort has been devoted to accelerating the decomposition kinetics by catalytic doping and by ball milling . [37] In order to take advantage of the total hydrogen capacity, the intermediate compound LiH must be dehydrogenated as well. Due to its high thermodynamic stability this requires temperatures in excess of 400 °C, which is not considered feasible for transportation purposes. Accepting LiH + Al as the final product, the hydrogen storage capacity is reduced to wt%. Another problem related to hydrogen storage is the recycling back to LiAlH 4 which, owing to its relatively low stability, requires an extremely high hydrogen pressure in excess of 10000 bar. [37] Cycling only reaction R2 — that is, using Li 3 AlH 6 as starting material — would store wt% hydrogen in a single step (vs. two steps for NaAlH 4 which stores about the same amount of hydrogen). However, attempts at this process have not been successful so far. [ citation needed ]
