The Difference between a COSHH and a Risk Assessment

              

Difference between a COSHH Assessment and a Risk Assessment

When looking at safe working practices and plumbing health and safety, RAMS traditionally stood for Risk Assessments and Method Statements, but now also includes COSHH Assessments. These documents serve as the framework for managing the various risks associated with specific plumbing tasks. Although a COSHH Assessment is essentially a type of Risk Assessment, this blog post aims to shed light on why they are both required.

The primary reason for RAMS and all workplace health and safety is to prevent illness or injury to any employees or any persons that may be harmed by employees' activities. This is called Duty of Care and refers to employers having a moral and legal responsibility to ensure the health and safety of their employees, and others that may be affected by the work process, protecting them from harm. And, the main health and safety document for most trades used to be a Risk Assessment. However, the Control of Substances Hazardous to Health Regulations (COSHH) were introduced in the UK in 1988 and came into force on 1st October 1989. These regulations were introduced to specifically address substances that people might encounter at the workplace or because of the work being carried out.

A Risk Assessment is designed to identify hazards and implement control measures to eliminate or reduce these hazards to an acceptable level, thereby mitigating the risks associated with carrying out a specific task. Hazards might include the tools used, the environment (such as working at height or in confined spaces), or hot works and fire risks.

Whereas a COSHH Assessment is not concerned with a task being carried out, but the risks inherent with using, storing, disposing, igniting, releasing or being contaminated by a substance.

A COSHH Assessment specifically addresses risks associated with individual substances. In addition to identifying potential risks present during workplace activities, a COSHH Assessment provides comprehensive details, including the classification of hazardous substances such as chemicals, dusts, fumes, gases, and biological agents. The process involves identifying these substances, evaluating the risks posed, and implementing appropriate control measures, such as personal protective equipment (PPE), ventilation, safe handling procedures, emergency response plans, and health monitoring. The primary objective is to systematically assess the use or production of hazardous substances in the workplace and ensure that adequate controls are established to safeguard health and safety.

A COSHH Assessment covers any substance that can cause harm to health, regardless of its form, and these include:

Chemicals: This category includes a broad range of substances containing harmful chemicals, such as solvents, heavy metals, and pesticides, which can pose considerable health risks upon exposure.

Gases and Fumes: This covers hazardous gases and vapours produced during industrial processes, such as welding fumes which may contain metal oxides and harmful particulates, as well as asphyxiating gases like carbon monoxide and hydrogen sulphide that can cause serious respiratory issues or even be fatal.

Vapours and Mists: Vapours refer to the gaseous phase of substances that can be inhaled, while mists consist of tiny liquid droplets suspended in the air. Both can originate from various processes, such as spraying paints or using aerosolised chemicals, and may cause irritation of the respiratory system or other health issues.

Dusts: This category includes fine particles released from mechanical processes, such as wood dust from sanding or silica dust generated during tile cutting. Breathing in these dusts can cause respiratory illnesses, such as silicosis or chronic obstructive pulmonary disease (COPD).

Biological Agents: These include a variety of microorganisms, such as bacteria, viruses, fungi, and parasites, that can cause infectious diseases. Exposure can happen in different environments, especially healthcare settings or industries where biological materials are handled.

Nanoparticles: This term describes extremely small particles, usually at the nanometer scale, which can have unique chemical and physical properties. Nanoparticles are found in a variety of products and processes, including cosmetics and electronics, and their inhalation or ingestion may pose unknown health risks because they can penetrate biological membranes.

Identifying health hazards from substances during normal use is only part of the COSHH regulations. Employees also need to know how to dispose of any waste substances, whether a substance is damaging to the environment or aquatic life. If a substance is flammable, it is important to understand its behaviour in a fire, such as being explosive or releasing poisonous gases. Additionally, the specific health risks need to be recorded, including what happens if a substance comes into contact with the skin, eyes, is inhaled, or ingested, as well as the relevant first aid procedures for dealing with any form of contamination. PPE, work exposure limits, and first aid details are also required.

In conclusion, both Risk Assessments and COSHH Assessments are designed to identify and reduce hazards, but a Risk Assessment focuses more on the risks associated with carrying out a task, while the COSHH Assessment concentrates on the use, storage, and accidental release of substances.
