What is the exposure limits for toluene?
What is the exposure limits for toluene?
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.
How explosive is toluene?
ICSC 0078 – TOLUENE. Highly flammable. Vapour/air mixtures are explosive. NO open flames, NO sparks and NO smoking.
Is toluene highly flammable?
What are fire hazards and extinguishing media for toluene? Flammable Properties: HIGHLY FLAMMABLE LIQUID. Can ignite at room temperature. Releases vapour that can form explosive mixture with air.
What is the NFPA code for toluene?
Highly flammable. Insoluble in water. TOLUENE reacts vigorously with allyl chloride or other alkyl halides even at -70°C in the presence of ethyl aluminum dichloride or ethyl aluminum sesquichloride. Explosions have been reported [NFPA 491M 1991].
What is the action level for toluene?
In the final rule, OSHA is establishing an 8-hour TWA PEL of 100 ppm and a STEL of 150 ppm for toluene.
Why is toluene hazardous?
Exposure to toluene can cause eye and nose irritation, tiredness, confusion, euphoria, dizziness, headache, dilated pupils, tears, anxiety, muscle fatigue, insomnia, nerve damage, inflammation of the skin, and liver and kidney damage. Workers may be harmed from exposure to toluene.
What is the molecular mass of toluene?
92.14 g/molToluene / Molar mass
How hazardous is toluene?
Is toluene prohibited?
Toluene is known as part of the so-called “toxic trio” of dangerous chemicals found in polishes, including formaldehyde, a preservative, and dibutyl phthalate, which gives polish a hard finish. The trio is banned in many foreign countries but is legal in the U.S. if it is listed on the ingredient list.
What is the molecular formula of toluene?
C7H8Toluene / Formula
Why is toluene ortho para directing?
Answer: (a) In toluene, methyl group is activating and ortho-para directing because it increases electron density at ortho and para positions.
What is the MSDS for toluene?
The substance may cause effects on the central nervous system. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. Exposure at high levels could cause cardiac dysrhythmia and unconsciousness.;The substance defats the skin, which may cause dryness or cracking.
Is toluene regulated by EPA?
Toluene is regulated as a hazardous air pollutant (EPA 2014a) and is subject to the emission limitations for various processes and operations in the synthetic organic chemicals manufacturing industry.
What is the molecular weight of toluene?
How many types of toluene are there?
Under normal conditions, toluene gives all three isomers, out of which ortho-derivative forms around 63 % and 34% of para-product and 3% of meta-product is formed.
What is the viscosity of toluene?
The proposed value for the viscosity of liquid toluene at 298.15 K and 0.1 MPa is η=554.2±3.3 μPa s.
What is the meaning of Upper Explosive Limit?
Upper explosive limits (UEL) are the maximum concentrations of a gas or vapor in the atmosphere that is able to generate a flash or a fire in the presence of an ignition source. A gas or vapor that has a higher concentration than the upper explosive limit will not be able to burn as it will be too rich.
What is the reactivity of toluene?
Reactivity Profile. TOLUENE reacts vigorously with allyl chloride or other alkyl halides even at -70° C in the presence of ethyl aluminum dichloride or ethyl aluminum sesquichloride. Explosions have been reported [NFPA 491M 1991]. Incompatible with strong oxidizing agents.
What is the explosive range of a gas?
This is the lowest concentration in the atmosphere of a gas or vapor that is required to generate a flash or a fire. The range between the lower and upper exposure limits is known as the explosive range. In the explosive range, a gas or vapor will readily ignite.
What are the different types of gases with explosion limits?
