Not sure if you’ve got a confined space ?

Some confined spaces are obvious, others aren't so easy to spot...

• Roof voids
• Hoppers
• Industrial boilers
• Cargo holds
• Trenches
• Wells
• Open topped pits
• Flour silos

The HSE define “A confined space is a place which is substantially enclosed (though not always entirely), and where serious injury can occur from hazardous substances or conditions within the space or nearby (e.g. lack of oxygen)”.

Assessment

It’s basically down to our old friend the risk assessment, and whilst some are obvious, most are not.

‘Specified risks’ to look for....

When in the potential ‘confined space’, could everyone escape quickly, without having to negotiate obstacles?

Is the exit nearby or is there only one exit?

An enclosed nature may not always be apparent, it may only be in one necessary location, and may only be intermittent.

Is there adequate ventilation?

Could toxic fumes, gases or vapours be present or flow in to the confined space or be created during the works?

Is there risk of serious injury arising from a fire or explosion in the ‘space’?

These gases may include flammable substances or too much oxygen.

Is there a foreseeable risk that the ‘space’ could flood with liquids or free flowing solids - preventing entrants breathing?

• Liquids which are toxic or inert e.g. water
• Free flowing solids - such as sugar, flour or coal dust

Is there too little oxygen?

Is it too hot?

Any of these could indicate a confined space. There are procedures you must put in place under the Health & Safety at Work etc Act 1974
