Safe Use of Chemicals and Hazardous Substances at Work

Handling chemicals and hazardous substances in the workplace can pose serious health risks to employees and others nearby. Employers are legally required to manage and control exposure to these substances to prevent injury and long-term health issues. Compliance with the Control of Substances Hazardous to Health Regulations 2002 (COSHH) is essential for workplace safety.

Understanding Hazardous Substances

Hazardous substances include chemicals, dust in the workplace, fumes, vapours, mists, and biological agents. These can cause harm through inhalation, skin contact, ingestion, or injection. Examples include:

  • Chemical solvents and cleaning agents
  • Dusts from wood, cement, or metal
  • Biological agents such as bacteria or viruses
  • Fumes and vapours from industrial processes

Legal Responsibilities for Employers

Under COSHH, employers must:

  • Identify hazardous substances in the workplace.
  • Assess the risks posed by these substances.
  • Implement control measures to reduce exposure, such as ventilation, PPE, and safe storage.
  • Provide appropriate training, supervision, and information to employees.
  • Regularly monitor and review the effectiveness of control measures.

Safe Handling and Control Measures

To protect workers and comply with COSHH regulations, consider the following measures:

  • Substitute hazardous substances with safer alternatives where possible.
  • Use engineering controls such as fume cupboards, local exhaust ventilation, or containment systems.
  • Provide Personal Protective Equipment (PPE) such as gloves, respirators, or protective clothing.
  • Store hazardous substances safely and label them clearly.
  • Ensure proper procedures for handling, mixing, and disposing of chemicals.

Risk Assessment and Monitoring

Conducting regular risk assessments is vital. Employers should:

  • Identify all hazardous substances and associated tasks.
  • Evaluate exposure levels and potential health impacts.
  • Implement control measures and review their effectiveness.
  • Keep records of assessments and employee training.

Training and Employee Competence

Employees should receive training to understand the risks associated with hazardous substances, correct handling procedures, and how to respond in an emergency. Key areas of training include:

  • Recognising hazardous substances and their labels.
  • Safe handling, storage, and disposal methods.
  • Emergency procedures for spills, leaks, or exposure.
  • Use and maintenance of personal protective equipment (PPE).

Recommended Training

By following COSHH guidance and implementing effective control measures, employers can minimise health risks, protect employees, and maintain a safe workplace environment.
