HSE has published new guidance on engineered stone and launched nationwide inspections as part of a major programme to tackle risks from silica dust.
The aim of the new guidance and inspection programme is to protect workers from silicosis, a serious and irreversible lung disease caused by breathing in engineered stone dust.
The deaths of 2 young workers in 2024 prompted urgent calls for action from MPs, trade unions, and medical professionals. Engineered stone, widely used in kitchen and bathroom worktops, can contain up to 95% crystalline silica.
Silicosis can develop within months or years, unlike natural stone, which may take decades. Workers can suffer permanent lung damage before any symptoms appear.
What the guidance says
The COSHH guidance for engineered stone sets out latest guidance for employers:
switch to low silica engineered stone
use on-tool water suppression and control mist - no dry cutting
provide appropriate respiratory protective equipment (RPE)
carry out regular health surveillance
Research shows dry cutting can expose workers to 5-10 times more respirable crystalline silica (RCS) than wet methods. Low-silica alternatives of equivalent quality are available, removing any justification for riskier practices.
Inspections underway
HSE inspectors will carry out over 1,000 visits to fabricators across Great Britain over the next 12 months. Enforcement action will be taken against those who fail to meet legal requirements.
Mike Calcutt, Deputy Director at HSE, said: "Silicosis is incurable but entirely preventable. The guidance is published, expectations are clear, and our inspectors are coming. Every worker should be safe from this deadly risk."
What you need to do
Employers are encouraged to check controls are in place and to read the new guidance.
Workers should know their rights and the controls that should protect them.
