A particular gas welding process in a confined space is suspected of producing dangerous concentrations of carbon monoxide, carbon dioxide, iron oxide particulate, and manganese fumes. Atmospheric sampling

A particular gas welding process in a confined space is suspected of producing dangerous concentrations of carbon monoxide, carbon dioxide, iron oxide particulate, and manganese fumes. Atmospheric sampling produces the following exposure data:

Period CO (ppm) CO2 (ppm) Iron Oxide Manganese
(mg/m3) (mg/m3)
8:00 am - 10:00am 10 1000 1 1
10:00am - 12:00pm 20 1000 4 1
12:00pm - 1:00pm 25 1000 2 0
1:00pm- 4:00pm 30 1000 3 1

Do the calculations to determine whether the combined exposure represents an OSHA violation.
