What is the permissible exposure limit for Hydrogen Peroxide according to the regulations?

1. 1.0 time at 50 ppm

2. 1.0 time at 75 ppm

3. 8 hour limit at 100 ppm

4. 1.0 time at 25 ppm

The correct answer is: 1.0 time at 75 ppm

The permissible exposure limit (PEL) for Hydrogen Peroxide is established to ensure worker safety during its handling. This limit is particularly necessary because Hydrogen Peroxide can be a potent irritant and has potential health effects at certain concentrations. The chosen answer reflects the most accurate permissible exposure limit, which is often established through safety regulations and occupational health guidelines. A PEL of 1.0 time at 75 ppm indicates that exposure to Hydrogen Peroxide can be sustained at this concentration for short durations without significant risk to health, making it a reasonable limit in industrial or healthcare settings where this chemical may be used. Regulatory agencies, such as the Occupational Safety and Health Administration (OSHA), set these exposure limits based on comprehensive studies and risk assessments. The value of 75 ppm signifies a careful balance between practicability and safety, taking into account the chemical's potential to harm health if exposure is prolonged or at higher concentrations. In contrast, other options may suggest higher or lower permissible levels which do not align with established safety guidelines, thereby not providing a feasible or safe limit for exposure in professional environments.
