What Is a Carcinogen and Why Should You Care?

Let’s cut straight to it:

A carcinogen is any substance that can cause cancer.

It might not happen today.

It might not happen next year.

But repeated or long-term exposure can cause damage to your cells that leads to serious illness — often decades later.

This is especially important in construction, where exposure to hazardous substances is part of daily life. And yet, most people on site don’t think twice about what they’re breathing in, touching, or cutting through.

🧪 What Makes Something a Carcinogen?

Carcinogens are materials or agents that can cause cancer by:

• Damaging DNA in your cells

• Causing inflammation that never switches off

• Interfering with how cells grow and divide

Some people are more vulnerable than others.

But one thing’s universal:

Prolonged exposure = increased risk.

🧱 Common Carcinogens Found on Construction Sites

Here are some of the biggest culprits you’ll come across — often without even realising the risk:

🔹Silica Dust

• Comes from cutting concrete, bricks, tiles, and stone

• Causes lung cancer and silicosis, a deadly lung disease

🔹Asbestos

• Still found in older buildings

• Causes mesothelioma, a rare but aggressive cancer

🔹Diesel Exhaust

• Present on most sites with machinery or generators

• Linked to lung and bladder cancer

🔹Solvents, Paints, and Adhesives

• Contain volatile organic compounds (VOCs)

• Some are classified as carcinogenic, especially with poor ventilation

🔹Insulation Fibres

• Older mineral wool and glass wool fibres can cause respiratory issues

• Handling without PPE? You’re taking a gamble

🔹Wood Dust

• Especially hardwoods like oak and beech

• Linked to nasal and sinus cancers

  
  

🧤 So What Can You Do About It?

You can’t always eliminate carcinogens but you can control your exposure.

Here’s how to protect yourself and your team:

✅ Check the MSDS (Material Safety Data Sheet)

Every product should come with one. It tells you what’s in it, how dangerous it is, and how to use it safely.

✅ Link your COSHH assessments into RAMS

RAMS (Risk Assessments and Method Statements) should identify carcinogens, and your COSHH assessment should lay out how to handle them.

✅ Use proper PPE and use it properly

• Respiratory protection (not a paper mask from Screwfix)

• Gloves rated for chemical resistance

• Goggles and overalls if needed

• Wash hands before eating or drinking

✅ Ventilation, extraction, isolation

• Don’t cut bricks in confined spaces

• Use water suppression and dust extraction

• Keep chemicals sealed and contained

✅ Don’t just trust the boss to protect you

They might not care.

They might be too busy.

They might not even know.

You have to look out for yourself.

🧠 Systemic Effects Don’t Show Up Right Away

This is the really scary part.

Long-term damage from carcinogens — like:

• Lung cancer

• Skin cancer

• Bladder cancer

• Infertility

• Chronic respiratory issues

  
  

…often doesn’t show up until years or decades later.

And by the time it does, it’s too late to go back and argue about whether you should’ve worn a mask that day you mixed insulation foam in an unventilated room.

If you have young children, or plan to start a family, or just want to live a long and healthy life now’s the time to take it seriously.

🚨 Final Word: Read the Damn Sheet

Every product you use from glue to cladding has a data sheet.

Read it.

Understand it.

Link it into your COSHH.

Build it into your RAMS.

Because no one else is going to care about your health as much as you do.

The materials used on the Grenfell Tower came with a safety data sheet.

They were chosen because they were cheaper — not because they were safe.

Don’t make that mistake in your own home.
