The highest value measured during the study period was 1.989 mg/[m.sup.3] in 2012; even this value was below the acceptable concentration of 3 mg/[m.sup.3] specified by the ACGIH
. Therefore, the work environment of the workplaces analyzed in this study may be considered appropriately controlled.
Although the spot environmental mercury vapor concentrations measured in this investigation cannot be directly compared with the time-weighted averages used in OSHA (9), NIOSH (10), and ACGIH
(1) guidelines, this investigation indicates increased risk for adverse health effects from mercury exposure to workers in fluorescent lamps recycling facilities, with potential for take-home exposure and environmental contamination.
None of the concentrations measured at three different positions in this facility was found to be above ACGIH
STEL, UAE STEL, and OSHA Ceiling Standards (Table 2).

can provide additional information, but remember that when looking into safety concerns, the only person that is looking out for the user is you.

Regarding the standard concentration of inhalable MDF dust set by American Conference of Governmental Industrial Hygienists (ACGIH
) , it was determined that the dust of all softwoods and hardwoods except western red cedar should have a threshold limit value (TLV) of 1 mg/[m.sup.3].
Health and safety professionals presume to insure researcher safety by measuring and documenting air velocity at the open face of the hood (ANSI/AIHA/ASSE 2012; ACGIH
Department of Labor, 2016), whereas the American Conference of Governmental Industrial Hygienists (ACGIH
) recommends an 8-hour TWA sound level of 85 dBA with a 3 dB exchange rate (ACGIH
The pDR-1500 was also set to a 1.7-L/min flow rate, which is the required flow rate as established by the American Conference of Governmental Industrial Hygienists (ACGIH
) for the metal/nonmetal industry."
