What does STEL stand for in occupational safety?

In the context of occupational safety, STEL stands for Short-Term Exposure Limit. This term refers to the maximum concentration of a specific substance that workers can be exposed to over a short period, typically defined as 15 minutes, without experiencing harmful effects. STEL values are established to protect workers from adverse health effects that can result from brief exposures to potentially hazardous substances, particularly those that may cause acute toxicity.

Employers use STEL guidelines to ensure that the work environment is safe and to minimize the risk of short-duration exposure to harmful levels of chemicals or radiation. By adhering to these limits, organizations can implement proper ventilation, provide personal protective equipment, and develop work practices that further reduce exposure.

The other options do not accurately represent the established meaning of STEL in occupational safety. Understanding and adhering to Short-Term Exposure Limits is crucial for maintaining a safe workplace and ensuring the health and well-being of employees.
