VOC Content Minus Water and Exempt Solvents

EHS refers to regulations, rules, and workplace programs to protect the health and safety of their employees, the public, and the environment from all hazards associated with the workplace. Therefore, effective monitoring of air quality is essential to prevent harmful environmental releases and illness in a work environment. According to Columbia Southern University (n.d.), samples such as source, area, population sample is usually taken for sampling. Besides, air analysis integrates air quality assurance and quality control aspects to monitor all the company processes.

Calculations for the following data;

A. One Gallon of Coating Data

VOC content (WV) = 2.8 lb. VOC per gal coating

Coating volume (VM) = 1.0 gal

Water content= 1.0 lb./gal

Water density= 8.34 lb./ gal

Exempt-solvent content = 0.5 lb./ gal

Exempt-solvent density= 6.64 lb. /gal

1. Gallons of water in one gallon of coating

VW= (1.0 lb. water) / gal water * (gal water / 8.34 lb water) = (0.12-gal water/ gal coating)

2. Gallons of exempt solvent (ES) in one gallon of coating

= lb./gal of coating * 1.0gal of ES/ 6.64 lb. /gal of ES

= (0.5 lb. / 1.0 gal) * (1.0gal of ES/ 6.64 lb. /gal of ES) = 0.08 gallons of ES/gal coating

3. Pounds of VOC in one gallon of coating (less the water and ES) per day

=WV/1.0gal of coating volume – gal of water volume-gal of ES)

2.8/ 1.0 gal of coating volume -0.12 gal of water volume – 0.08 gal of ES)

= 2.6 lb. of VOC/gal of coating (less water and ES volume) per day

4. The work system is not in compliance with the state requirements since it generates a total of 9.2 lb. VOC/5-hour day, 3.2 more than the 6.0 lbs. of VOC/5-hour state requirements.
