No activity should begin unless a plan for the disposal of nonhazardous waste and hazardous waste has been formulated. When a person walks in front of a fume hood, the vortices can overcome the fume hood face velocity and pull contaminants out of the fume hood, into the vortex, and into the laboratory. Face velocities that are too high or too low will reduce the containment efficiency of a fume hood. It is important to place chemical sources and apparatus at least 6 inches behind the face of the hood to promote containment. The use of cooling water in laboratory condensers and other equipment is a common laboratory practice, but can create a flooding hazard by hoses popping off under pressure fluctuations in the water supply.
Electrical shock is a major electrical hazard.
A relatively low current of 10 milliamperes poses some danger, and 80 to 100 milliamperes can be fatal. Answer the questions as completely as possible. Explain what you would do in case of a fire. Explain what you would do in case of a large hazardous chemical waste spill. Explain what you would do in case of a tornado.
