HSE Reinforces COSHH Compliance Amidst Rising Workplace Chemical Exposure Concerns

The Health and Safety Executive (HSE) has recently reiterated and updated its guidance on the Control of Substances Hazardous to Health (COSHH) Regulations 2002, urging UK businesses to review and enhance their procedures for managing hazardous substances. This comes as workplace exposure to chemicals continues to be a significant concern, contributing to thousands of occupational ill-health cases annually.

The updated guidance aims to simplify compliance for employers, particularly small and medium-sized enterprises (SMEs), by providing clearer directives on risk assessment, control measures, and health surveillance. The HSE’s renewed focus underscores the enduring importance of COSHH in preventing a wide range of health issues, from dermatitis and asthma to various cancers, all linked to exposure to hazardous substances.

Understanding COSHH: A Legal Imperative

COSHH is a cornerstone of workplace health and safety legislation in the UK, legally obliging employers to protect their employees from harm caused by hazardous substances. These substances can take many forms, including chemicals, fumes, dusts, vapours, mists, nanotechnology, gases and biological agents (germs). The regulations apply across virtually all industries, from manufacturing and construction to healthcare and cleaning services.

A key aspect of the HSE's updated advice is the emphasis on a hierarchical approach to control measures. This means employers should always strive to eliminate the use of hazardous substances where possible. If elimination is not feasible, substitution with a less hazardous alternative should be considered. Only then should engineering controls (e.g., ventilation, enclosed processes), administrative controls (e.g., safe systems of work, reduced exposure times), and finally, personal protective equipment (PPE) be implemented.

  • Elimination: Removing the hazardous substance entirely.
  • Substitution: Replacing it with a safer alternative.
  • Engineering Controls: Modifying the workplace or process to reduce exposure.
  • Administrative Controls: Implementing safe work practices and procedures.
  • Personal Protective Equipment (PPE): Providing equipment like gloves, masks, and eye protection as a last resort.

The HSE stresses that PPE, while crucial, should never be the sole or primary control measure, as it offers a less robust level of protection compared to controls higher up the hierarchy.

Key Updates and Practical Implications for Businesses

The renewed guidance from the HSE places a strong emphasis on several critical areas:

  1. Robust Risk Assessment: Employers must conduct thorough risk assessments to identify all hazardous substances in the workplace, evaluate the risks they pose, and determine who might be harmed and how. This assessment should be regularly reviewed and updated, especially if there are changes to processes, substances, or equipment. The HSE provides templates and examples to assist businesses in this process.
  2. Effective Control Measures: Beyond merely identifying hazards, businesses must implement and maintain effective control measures. This includes ensuring that local exhaust ventilation (LEV) systems are correctly installed, regularly tested (at least every 14 months for most systems, as per HSG258), and properly maintained. Training for employees on the correct use of controls and PPE is also paramount.
  3. Health Surveillance: For certain high-risk substances or processes, health surveillance may be required. This involves a planned programme of health checks to detect early signs of work-related ill health and to assess the effectiveness of control measures. Examples include spirometry for workers exposed to respiratory sensitisers or skin checks for those handling irritants. Employers must ensure that health surveillance is carried out by a competent person, such as an occupational health professional.
  4. Information, Instruction, and Training: Employees must be fully informed about the risks associated with the substances they work with, how to use control measures effectively, and what to do in case of an emergency. This training should be ongoing and tailored to the specific roles and responsibilities of the workers.

According to HSE statistics, an estimated 12,000 deaths each year are linked to past exposures at work, primarily to chemicals and dust. Furthermore, around 17,000 new cases of breathing or lung problems caused or made worse by work are reported annually. These figures highlight the significant human and economic cost of inadequate COSHH compliance.

Enforcement and Penalties

The HSE, along with local authorities, is responsible for enforcing COSHH Regulations. Non-compliance can lead to severe penalties, including fines and imprisonment. In recent years, there have been numerous successful prosecutions against companies failing to meet their COSHH obligations, with fines often running into hundreds of thousands of pounds. For instance, a manufacturing company was fined £200,000 in 2022 after an employee developed occupational asthma due to inadequate control of sensitising agents.

The HSE encourages businesses to utilise the wealth of free resources available on its website, including guidance documents (e.g., L5, HSG258), COSHH essentials sheets, and case studies, to help them understand and meet their legal obligations.

Ensuring robust COSHH compliance is not just a legal requirement but a fundamental commitment to employee well-being and operational resilience. For businesses seeking to enhance their understanding and implementation of COSHH, or indeed other critical health and safety topics, expert training can be invaluable.
