Calculate the overall risk score for the chemical storage area (scale of 1 to 10). In a chemical manufacturing plant, you are tasked with assessing the risk associated with a specific chemical storage area. The area contains various chemicals with different hazardous properties. You must consider not only the likelihood and consequences but also assign subjective weights to each consequence level based on their perceived severity.

2. In an industrial facility, a ventilation system is used to control air quality in a production area. The facility needs to increase the airflow rate of 15,000 cubic feet per minute with a pressure of 2.5 inches of water column. Calculate the new airflow rate if the fan speed is increased to 1,400 RPM while keeping pressure constant. (N1=1,200 RPM)

3. A worker is conducting maintenance on a tall communications tower. During a fall, the fall arrest system deploys and comes to a stop in 0.75s. Calculate the fall distance the worker fell before the fall arrest system stopped the fall. Consider the acceleration due to gravity as 9.81 m/s^2.

4. Sound pressure level (SPL) —> 90dB. The reference is 20 micro pascals. Asked: P1 (the measured sound pressure)

5. In a computer server room, engineers are exposed to potentially harmful electromagnetic fields generated by the servers. The initial exposure level is measured at 200 milligauss (mG). The company decides to implement electromagnetic shielding to reduce exposure. After installation, the exposure level drops to 40 mG. The safety standards mandate a minimum reduction of 70%. Calculate the reduction in exposure using the Exposure Reduction Formula and determine if it meets the safety standards.

6. In a data center, a containment system is used to manage cooling airflow and prevent hot and cold air from mixing. The system effectively contains 80% of the hot air within the designated areas, while 20% of the hot air mixes with the cold airflow. Assess the containment efficiency using the Containment Efficiency Formula to determine if the system is effective.

7. In a server room, engineers need to ensure adequate airflow to prevent server overheating. The room has a volume of 60 cubic meters, and the company requires a minimum of 10 air changes per hour for proper cooling. Calculate the required airflow rate (Q) using the Airflow Rate Formula to ensure the servers remain cool.

8. Computer engineers frequently need to lift and install heavy server racks weighing 60 kilograms. The safety limit for lifting force is set at 300 Newtons (N). They apply an upward force of 200 Newtons to lift the server rack. Determine whether the force exerted by the engineers is within safe limits for lifting server racks.

9. In a data center, computer engineers frequently need to access equipment on high server racks. The safety limit for the maximum reach distance is set at 90 centimeters (cm). The engineers' average elbow height from the floor is 115 cm. Calculate the maximum allowable horizontal reach (R) using the Reachability formula and assess if it meets the safety limit.
