THE SAFETY BRIEF

The Dust That Steals Your Breath

Silica, air quality and the long-term impact on construction workers.

You may not see it. You make not feel it. But the damage from silica dust can build quietly over time. Here's what every site team needs to know and how to protect themselves.

SCROLL TO READ

What is silica and why is it a problem?

Respirable crystalline silica (RCS) is a very fine dust created when materials containing silica (e.g. concrete, stone, brick, mortar, tiles and asphalt) are cut, drilled, chased or demolished.

These tiny particles can become airborne and travel deep into the lungs, where they can cause serious and irreversible damage.

The Health and Safety Authority (HSA) warns that even small amounts of respirable crystalline silica can be harmful, and that the dust may be invisible to the naked eye.

The hidden impact over time

Silica-related diseases often develop slowly. You might feel fine today, but repeated exposure can have serious consequences in the years ahead.

Today

Healthy lungs

Lungs work efficiently with clear airways and healthy tissue.

After 5 years

Early changes

You may still feel fine, but inflammation and early scarring can begin. Possible persistent cough and reduced stamina.

After 10 years

Growing damage

Breathlessness, reduced lung function and scarring (silicosis) may be evident. More frequent chest infections.

After 20 years

Long-term consequences

Significant loss of lung function. Increased risk of silicosis, COPD, lung cancer and other serious health problems.

Real risks. Real people.

"It sneaks up on you. You don't feel it as first, but years later, simple things like climbing stairs or playing with your kids can leave you breathless."

The HSA highlights the serious health risks associated with silica, including:

Silicosis (irreversible lung disease)

Lung cancer

Chronic obstructive pulmonary disease (COPD)

Kidney disease and certain autoimmune diseases

Increased risk of tuberculosis

How to protect yourself and your team

The HSA recommends a combination of control measures. Respiratory protection is the last line of defence.
