Figure 1 shows the percent of employees personally monitored that were found to be in compliance with the OSHA PEL
for CO each year.
The best available science, to our understanding, shows that the current OSHA PEL
for quartz of 100 micrograms per cubic meter of air is appropriate to protect against silica-related disease, provided it is adhered to strictly.
25 hour work period, unprotected, would result in an exposure level less than the OSHA PEL
An OSHA plant inspection conducted after the diagnosis of pulmonary fibrosis in the process helper documented one airborne cobalt level at 90% of the OSHA PEL
If exposures are detected that approach or exceed the OSHA PEL
, it is advisable to proceed directly to real-time engineering sampling methods.
However, neither method reduces worker lead exposures to levels below the OSHA PEL
Stack testing was undertaken on two dust collectors, and silica exposure results indicate control well within the OSHA PEL
