Are there any health and safety limits to rubber fumes and dust?

Yes indeed! In order to safeguard workers well being and safety in environments where rubber fumes and dust are present certain limits are put in place by regulatory bodies. These limits dictate the concentrations of rubber fumes and dust that employees can safely encounter during an 8 hour workday period Employers are obligated to monitor these levels.
 
In the UK the Health and Safety Executive (HSE) establishes exposure limits for rubber fumes and dust. They enforce workplace safety rules and regulations providing Workplace Exposure Limits (WELs) under the Control of Substances Hazardous to Health (COSHH). These limits determine the levels of different airborne pollutants like rubber fumes and dust that workers can encounter in a typical workday. 

The Health and Safety Executives Workplace Exposure Limits (WELs) commonly follow recommendations like those of the European Union and ACGIH; however they are customised to meet UK regulations. Businesses in the UK must comply with these restrictions by enforcing measures and consistently overseeing air quality to safeguard employees well being against risks such as rubber fumes and dust particles. 

The International Labour Organisation (ILO), along with the World Health Organisation (WHO) offer advice. Suggest exposure limits to safeguard the well being of employees globally. 

These groups establish safety thresholds informed by studies to minimise risks from long term exposure; it is the duty of employers to follow these guidelines and oversee air quality in the workplace to ensure safe conditions are upheld.
