What are the regulatory requirements for airborne nitrosamine monitoring?

Regulatory requirements for airborne nitrosamine monitoring vary by country and sector. Here is a summary of the main frameworks.

United Kingdom

The Health and Safety Executive (HSE) has published guidance on nitrosamine exposure in rubber processing environments, with recommended occupational exposure limits for specific compounds including NDMA and NDEA. Employers in industries where nitrosamine formation is a known risk have a duty to monitor and control exposure under the Control of Substances Hazardous to Health (COSHH) Regulations.

Germany

TRGS 552 (Technical Rules for Hazardous Substances) sets binding workplace limits for N-nitrosamines. Germany has some of the most specific regulatory requirements for nitrosamine monitoring in occupational settings.

United States

OSHA and NIOSH have issued guidance on nitrosamine exposure in manufacturing environments. While formal permissible exposure limits are not set for all nitrosamines, NIOSH has recommended exposure limits for several compounds and recommends minimising exposure wherever possible.

Voluntary monitoring

Many organisations conduct monitoring programmes ahead of formal regulatory requirements, particularly in sectors where nitrosamine formation risk is known but compound-specific limits have not yet been formally set. Proactive monitoring provides baseline data and demonstrates duty of care.
