Hazardous Substances

According to COSHH (Control of Substances Hazardous to Health), hazardous substances are: “Those that are: Very Toxic, Toxic, Corrosive, Harmful or Irritant”. This includes any substance that has been allocated a Workplace Exposure Limit (WEL), previously known as MEL. Once identified, any hazardous substances in your workplace need to be assessed for potential risk by an individual qualified to do so. Assessment of the following areas is vital: quantity, handling, storage, exposure, use, disposal, accident and emergency procedures and spill response.

Hazardous Waste

According the HSE (Health and Safety Executive), Waste is considered “hazardous” if it, “contains substances or has properties that might make it harmful to human health or the environment”. Crucially, substances were re-classified placing many within the “hazardous” category which required companies to re-think their handling and disposal procedures. Since July 2014, it is an offence to dispose of hazardous waste along with non-hazardous waste in landfill. Examples of hazardous waste include mercury, bromine, asbestos, solvents, pesticides and oils. There are a number of resources available to you that will help you classify different types of waste.

Hazardous substances surround us, information and knowledge are a vital resource to protect the workplace as well as the environment.

How is Hazardous Waste Cleaned Up?

Employers have a duty of care to ensure all hazardous materials are handled correctly and cause no harm. They also have a duty of care to ensure all hazardous substances are disposed of safely and correctly causing no harm to health or to the environment. The COSHH regulations of 2004 cover all activities with hazardous substances. The regulations are useful guidelines for employers and business owners or anyone responsible for safety in the workplace. For large or dangerous spills, calling a professional chemical clean-up company is always the safest option. A professional and experienced company will be properly equipped and technically able to deal with hazardous chemicals in any situation without unnecessary risk to health. For small spills, or clean-up of less harmful substances you will need to follow COSHH guidelines for each substance.
