What is the PEL for toluene?
200 ppm
OSHA: The legal airborne permissible exposure limit (PEL) is 200 ppm averaged over an 8-hour workshift, 300 ppm not to be exceeded during any 15-minute work period, and 500 ppm as a 10-minute acceptable maximum peak during an 8-hr workshift.
What are safe levels of toluene?
The ACGIH has an exposure limit for toluene of 100 ppm as an 8-hour TWA and 150 ppm as a 15-minute STEL; NIOSH recommends a 100-ppm 8-hour TWA and a 10-minute ceiling of 200 ppm.
What level of PPE is required for handling toluene?
Eye/Face Protection: Wear chemical safety goggles and face shield when contact is possible. Skin Protection: Wear chemical protective clothing e.g. gloves, aprons, boots.
What is IDLH for toluene?
The NIOSH IDLH concentration for toluene is 500 ppm.
What is the OSHA PEL for an 8-hour period?
OSHA. The current PEL for OSHA standards are based on a 5 decibel exchange rate. OSHA’s PEL for noise exposure is 90 decibels (dBA) for an 8-hour TWA.
What is the OSHA PEL for CO?
50 parts per million
What are the OSHA standards for CO exposure? The OSHA PEL for CO is 50 parts per million (ppm). OSHA standards prohibit worker exposure to more than 50 parts of CO gas per million parts of air averaged during an 8-hour time period. The 8-hour PEL for CO in maritime operations is also 50 ppm.
Is toluene a VOC?
Toluene, benzene and styrene are volatile organic compounds (VOCs) widely distributed in the environment. Tobacco smoke, traffic exposure and solvents used for paints, rubber and adhesives are known sources for these compounds.
Is toluene regulated?
Because of its potential to cause adverse health effects in exposed people, toluene is also regulated by the drinking water standards set by the EPA. Toluene generally gets into drinking water by improper waste disposal or leaking underground storage tanks.
Is toluene polar or non polar?
Nonpolar solvents include alkanes (pentane, hexane, and heptane) and aromatics (benzene, toluene, and xylene). Other common nonpolar solvents include acetic acid, chloroform, diethyl ether, ethyl acetate, methylene chloride, and pyridine.
How do you calculate PEL?
An example with values inserted would be if an employee was exposed to Substance A which has an eight-hour TWA of 100 ppm. The exposure is as follows: Two hours exposure at 150 ppm, two hours at 75 ppm and two hours at 50ppm (2×150 + 2×75 + 4×50)÷8 = 81.25 ppm .
What is the Acgih TLV for toluene ppm?
The ACGIH (2013) recommends an 8-hour TWA Threshold Limit Value (TLV) of 20 ppm toluene to protect against visual impairment and female reproductive effects including pregnancy loss. NIOSH has established a recommended exposure limit (REL) of 100 ppm that should not be exceeded at any time (NIOSH 2011).
