What is the STEL (short term exposure limit) for benzene?

The short-term exposure limit (STEL) for benzene is established to protect workers from the adverse health effects of exposure to this hazardous substance over a short duration. The STEL represents the maximum concentration of benzene in the air that a worker can be exposed to for a short period, usually around 15 minutes, without experiencing harmful effects. Recognizing that benzene is a cytotoxic agent and a known carcinogen, health and safety regulations are very strict regarding its permissible levels in the workplace.

In this case, 5.0 PPM as the STEL is aligned with accepted safety guidelines aimed at minimizing the risk of acute health issues and long-term damage from benzene exposure. This concentration is lower than the average OSHA permissible exposure limit (PEL) for benzene, which underscores the importance of limiting short-term exposure to ensure worker safety.
