Answer:
What is the Control Environment?
The control environment is the comprehensive set of actions taken by management that set the tone for how employees engage in their day-to-day activities. The control environment is comprised of all policies and procedures, the actions taken by management to deal with issues, and the values they espouse. Taken as a whole, the control environment shows the level of support that management has for the system of internal controls.
Environmental monitoring
Environmental control is an important aspect of inhalation system design. Unusual environmental conditions may place an additional, undesirable, stress on test animals. Variations in environmental factors such as temperature, relative humidity, atmospheric pressure, airflow, air quality, noise, and vibration could affect experimental animals and exposure atmospheres (Bernstein and Drew 1980; Hinners 1978; Phalen 1984). It is important that all chambers used in a study be controlled within the same environmental limits to ensure comparability between groups (Cheng et al. 1989). Computer control and monitoring of environmental conditions is recommended to provide consistent operating conditions, documentation of actual conditions in the exposure chambers, and alarms if any of the measured parameters are not within preset limits.
