Control of Noise at Work Regulations 2005 — Pressure Washers & Vacuums

Control of Noise at Work Regulations 2005 — noise exposure limits for cleaning equipment operators

The Control of Noise at Work Regulations 2005 require employers to prevent or reduce risks to health and safety arising from exposure to noise at work. They apply to all employers in all sectors where workers are exposed to noise — including construction, manufacturing, facilities management, and cleaning and pressure washing operations.

Industrial pressure washers and high-powered vacuums can generate significant noise levels. This page explains the legal exposure limits, what employers must do, and which V-TUF equipment operating characteristics are relevant to Noise at Work compliance.

The noise exposure limits

The Noise Regulations set three action values and one limit value, all based on daily personal noise exposure (LEP,d) measured in dB(A) or peak sound pressure in dB(C):

Lower Exposure Action Value (LEAV): 80 dB(A) LEP,d / 135 dB(C) peak — at or above this level, employers must make hearing protection available and provide information and training on noise risks. Workers must be able to request and receive hearing protection.
Upper Exposure Action Value (UEAV): 85 dB(A) LEP,d / 137 dB(C) peak — at or above this level, employers must: reduce noise exposure using engineering or administrative controls, establish hearing protection zones, ensure hearing protection is worn (not just available), and implement a hearing surveillance programme.
Exposure Limit Value (ELV): 87 dB(A) LEP,d / 140 dB(C) peak — workers must never be exposed to noise above this level, taking into account the attenuation provided by any hearing protection worn.

The 85 dB(A) UEAV is the most significant threshold in practice. Once a worker’s daily noise exposure reaches or exceeds 85 dB(A), hearing protection becomes legally mandatory — not optional.

Noise levels from pressure washing and vacuum equipment

Typical noise levels from industrial pressure washing and vacuum equipment:

Petrol pressure washers (TORRENT range, DD080, GB080): 90–100 dB(A) at operator position. Petrol-engine equipment routinely exceeds the 85 dB(A) UEAV. Operators must wear hearing protection. For sustained daily use, time limitations may be required to keep LEP,d below the 87 dB(A) ELV.
Electric pressure washers (HDC140, VTUF range, RAPID electric): typically 72–82 dB(A) at operator position, depending on pump type and operating pressure. Many electric units operate below the 80 dB(A) LEAV, making them preferable in noise-sensitive environments such as hospital grounds, school sites, and residential areas.
Industrial vacuums (MAMMOTH range, M-Class and H-Class extractors): typically 70–82 dB(A). Most V-TUF vacuum equipment operates below the 85 dB(A) UEAV, though sustained operation in enclosed spaces can increase effective exposure.

Actual noise exposure depends on the specific machine, operating conditions, distance from the source, enclosure, and duration of use. Employers are required to carry out a noise risk assessment specific to their operation — the figures above are indicative only.

Choosing lower-noise equipment — the engineering control hierarchy

The Noise Regulations require employers to consider engineering controls before relying on hearing protection. Choosing quieter equipment is the highest-order control available. In pressure washing applications, this means:

Gearbox-driven over direct drive: gearbox-driven pressure washers (GB080) run the pump at reduced RPM compared to direct-drive equivalents (DD080) — typically 3–5 dB(A) quieter. In sustained daily operations, this may be the difference between operating above and below the 85 dB(A) UEAV.
Electric over petrol: electric pressure washers eliminate engine noise entirely. In noise-sensitive environments, electric units are the appropriate specification.
Operational controls: directing the spray away from hard reflective surfaces reduces noise at the operator position. Limiting continuous daily run time reduces LEP,d without changing the machine.

Recommended lower-noise V-TUF equipment
