Overview of COSHH Compliance
What does COSHH cover?
First, identify the substances that are subject to the COSHH regulations and those that are not.
Purchased products
(e.g. paints, adhesives)
Process emissions
(e.g. dusts, welding fumes)
Biological material
(e.g. pigeon droppings, blood)
Contaminants
(e.g. used engine oils)
Despite the widespread prevalence of these substances within the construction sector, you must still identify and take note of any instances when they are present on your sites. However, it’s worth noting that some notable substances do not fall under COSHH regulations because they have their own regulations. These include, but are not limited to:
- Asbestos
- Lead
- Radioactive material
- Physically induced risks
- Therapeutic agents
- Cosmetics
- Items of PPE
- Explosives
- Articles
Remember: COSHH covers exposure to a substance. If you are not exposed to the substance in the workplace, you are not required to complete a COSHH assessment.
Having identified the substance, your first duty is to prevent employees from being exposed to it. There are multiple ways to prevent and control exposure at your construction sites. We recommend employing the hierarchy of controls.
Elimination
Physically remove the hazard (if possible). E.g. buy pre-coated materials to prevent use of paints; or replace welding with riveting.
Substitution
Substitute potentially harmful substances with something less hazardous. E.g. replace solvent-based products with water-based alternatives.
Engineering Controls
Control the hazard by isolating your workforce from it. E.g. Enclosed systems and Local Exhaust Ventilation (LEV).
Administrative Controls
Adjust the way people work to reduce the level of exposure to the hazard. E.g. introduce changes such as training, procedure changes, warning, signs and labels.
PPE
If Personal Perotective Equipment (PPE) is required, make sure that you select the correct type. Often, the type of equipment required can be just as varied as the substances themselves. PPE includes hard hats, respirators, safety glasses and hi-vis clothing.
