COSHH Regulation 9

Every year thousands of people are injured at work. Some of this is from breathing in dust and fumes and other hazards in the air at work. For this reason, the Health and Safety Executive (HSE) estimates that 12,000 deaths a year are from exposure to chemicals and dust. The LEV Regulations, also known as  COSHH Regulation 9 covers the use of LEV systems. COSHH Regulation 7 requires that:

The COSHH Regulation 9 logo


“Every employer shall prevent or, where this is not reasonably practicable adequately control the exposure of their employees to substances hazardous to health”

Employers often use Local Exhaust Ventilation (LEV) systems to ensure adequate control. In particular, LEVs cause the movement of suspended particles or harmful gases in the air away from the employee’s breathing zone. The LEV then removes the hazardous substance from the working environment.

LEV Regulations – COSHH Regulation 9

Over time an LEV system’s performance will diminish due to blockages, wear, damage and leaks. Therefore, the LEV Regulations  require through COSHH Regulation 9:

The LEV Regulations, in particular, COSHH Regulation 9 require that hoods are labelled after examination


In summary, “Where the regulation is met through the use of engineering controls, the employer shall ensure that thorough examination and testing of those controls are carried out. In the case of local exhaust ventilation plant, this will be at least once every 14 months…..”

Therefore, it is a legal requirement, through COSHH Regulation 9, that employers using  LEV systems must ensure that that they are operating effectively. In particular, the LEV Regulations require that Local Exhaust Ventilation Examination and Testing are carried out at least once every 14 months.

The HSE states that around 100,000 businesses in the UK use LEV Systems to control airborne hazards. This equates to 2.6 million workers. Only 40,000 of these businesses have their LEV systems tested regularly. Consequently, this leaves 60,000 businesses open to a contravention of the COSHH regulations. To put it another way, this leaves 1.6 million workers potentially at risk.
