TLVs

Definition

TLVs, or Threshold Limit Values, are guidelines for exposure limits to chemical substances and physical agents in the workplace.

Purpose

The purpose of TLVs is to protect workers from health hazards by establishing safe exposure limits for various substances and conditions. These guidelines help employers maintain a safe working environment and comply with occupational health regulations.

Examples of Use

1. Industrial Hygiene: TLVs are used to set permissible exposure limits for chemicals in manufacturing and industrial settings.
2. Construction Sites: Monitoring of dust, fumes, and noise levels on construction sites is guided by TLVs to ensure worker safety.
3. Laboratories: TLVs help regulate exposure to hazardous chemicals in research and medical laboratories.

Related Terms

• Occupational Exposure Limits (OELs): Limits on the amount or concentration of a substance in the air intended to protect workers' health.
• Permissible Exposure Limit (PEL): Regulatory limits on the amount or concentration of a substance in the workplace air set by OSHA.
• Material Safety Data Sheet (MSDS): A document that provides information on the properties, hazards, and safe handling of chemicals.

Notes

• Review and Update: TLVs are periodically reviewed and updated based on new scientific data and research.
• Compliance: Employers must ensure that workplace conditions do not exceed TLVs to protect workers’ health.
