What is the PEL of isopropyl alcohol from OSHA standards?

What is the OSHA PEL?

Related Pages. OSHA sets permissible exposure limits (PELs) to protect workers against the health effects of exposure to hazardous substances. PELs are regulatory limits on the amount or concentration of a substance in the air. They may also contain a skin designation.

What is OSHA’s standard permissible exposure limit or PEL?

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. Levels of 90-140 dBA are included in the noise dose. PEL can also be expressed as 100 percent “dose” for noise exposure.

Is 70 percent isopropyl alcohol flammable?


Is 5% isopropyl alcohol flammable?

How Flammable is Isopropyl Alcohol? Isopropyl alcohol is highly flammable and can easily ignite. Vapors may form explosive mixtures with air, traveling to a source of ignition and flash back, and use of water spray to fight fires may be inefficient.

What is an 8 hour TWA?

“TWA is the employee’s average airborne exposure in any 8-hour work shift of a 40-hour work week which shall not be exceeded.” The 8-hour TWA PEL is the level of exposure established as the highest level of exposure an employee may be exposed to without incurring the risk of adverse health effects.

What is PEL and STEL?

Permissible exposure limit (PEL) is a regulatory limit on the amount or concentration of a substance in the air. This is usually based on an eight-hour time weighted average (TWA), although some are based on short-term exposure limits (STEL). Workplace environmental exposure limit (WEEL) may be expressed as TWA.

What is a type of PEL?

PEL/TLV/REL have 3 subcategories: time-weighted average (TWA), ceiling value, and short term exposure limit (STEL).

What is permissible exposure level?

Definition. A Permissible Exposure Limit (PEL) is the maximum amount or concentration of a chemical that a worker may be exposed to under OSHA regulations.

What is the fire hazard level of isopropyl alcohol?

DANGEROUS FIRE HAZARD. OSHA: The legal airborne permissible exposure limit (PEL) is 400 ppm averaged over an 8-hour workshift. NIOSH: The recommended airborne exposure limit (REL) is 400 ppm averaged over a 10-hour workshift and 500 ppm, not to be exceeded during any 15-minute work period.

What is the functional group of isopropyl alcohol?

As a propyl group linked to a hydroxyl group, it is the simplest example of a secondary alcohol, where the alcohol carbon atom is attached to two other carbon atoms, sometimes shown as (CH3)2CHOH.
