Which of the following is true about the TLV of pentaborane?

The correct option indicates that pentaborane has a low Threshold Limit Value (TLV). A low TLV suggests that the substance is deemed to have significant health risks even at relatively low exposure levels. TLVs are established based on comprehensive toxicological and epidemiological data, and they offer guidelines for acceptable exposure limits to protect workers from harmful effects associated with inhaling, skin contact, or other forms of exposure to the chemical.

Pentaborane, being a compound that contains boron and is often used in specialized applications, is known to have toxic effects. In the context of industrial hygiene, the designation of a low TLV reflects the need for stringent controls and monitoring when working with this substance to ensure the safety of those exposed. It underscores the importance of minimizing occupational exposure to create a safe working environment and prevent potential acute or chronic health effects associated with exposure.
