When thinking about the Control of Substances Hazardous to Health (COSHH) Regulations, many employers focus on traditional workplaces such as factories, laboratories, or warehouses. However, with remote and hybrid work becoming more common across various industries, it’s important to understand that COSHH still applies — even in home-based environments.

In this article, we explore how COSHH impacts remote workers, what employers are responsible for, and how to manage hazardous substance risks outside of the traditional workplace.

Does COSHH Apply to Remote Workers?

Yes. Employers have a legal duty under COSHH to protect all employees who may be exposed to hazardous substances during work activities — regardless of where they work. If a remote worker is using or exposed to any hazardous substances as part of their role, COSHH regulations still apply.

Examples might include:

  • Cleaning or disinfecting products used in home healthcare roles

  • Inks, adhesives, or solvents used in home-based production or repair work

  • Dusts or particles generated during manual or craft-based tasks

  • Toners or chemicals used by employees managing specialist equipment from home

Even if the risk is low, employers must still assess and control potential exposure.

Common Misconceptions About COSHH and Remote Work

“They’re working from home, so it’s their responsibility.”

Wrong. If the activity is being carried out for work purposes and involves hazardous substances, the employer remains responsible for managing the risk.

“Domestic products don’t need a COSHH assessment.”

Not necessarily. Many household products used for work (like bleach, disinfectants, or sprays) can still be hazardous with repeated use or improper handling. If they’re used in a work context, they fall within COSHH scope.

“The risk is minimal, so we don’t need to do anything.”

Even low-risk scenarios require basic control measures and documentation. Neglecting them could lead to ill health, liability, or compliance issues.

How to Manage COSHH Risks for Remote Workers

1. Identify Activities That Involve Hazardous Substances

Review the roles and tasks performed remotely to identify potential exposure. Consider:

  • Work-related cleaning or hygiene routines

  • Use of chemicals or materials

  • Maintenance of equipment (e.g. printers, tools)

Speak with staff to understand what substances they’re actually using in their home environment.

2. Carry Out a COSHH Risk Assessment

For each identified substance:

  • Review the Safety Data Sheet (SDS)

  • Assess the frequency and method of use

  • Determine the route of exposure (e.g. skin contact, inhalation)

  • Identify necessary controls, such as PPE, ventilation, or safe storage

Document your findings and update them as needed.

3. Provide Clear Instructions and Training

Remote staff should understand:

  • What substances they’re using

  • How to use them safely

  • What PPE (if any) is required

  • How to deal with spills or accidental exposure

Training can be delivered online, and instructions should be accessible at all times.

4. Supply the Right Equipment

If specific products, PPE, or tools are needed to safely carry out a task, it’s the employer’s responsibility to provide them — not the employee’s. This includes:

  • Safer alternatives to hazardous substances

  • Gloves or eye protection (if required)

  • Secure containers or ventilation aids

5. Monitor and Review

COSHH assessments for remote workers should be reviewed periodically, especially if:

  • The tasks or substances used change

  • An incident or health concern is reported

  • New staff begin remote roles with exposure potential

Keep a central record of assessments, training, and any communications provided.

Final Thoughts

Remote work does not remove your responsibilities under COSHH. If hazardous substances are used as part of an employee’s work, it’s up to you to ensure their safety — whether they’re on-site or at home. A simple, practical approach can go a long way in managing risk and maintaining compliance.

At SIS Ltd, we help businesses carry out COSHH assessments and provide support tailored to both traditional and remote working environments. If you’re unsure whether your remote work practices are compliant, our team is here to guide you.
