🧪 COSHH Guide for Safe Handling of Hazardous Substances

Decent Cleaning — Professional Standards & Compliance

🧱 1. Purpose of This Guide

This COSHH guide ensures every Decent Cleaning team member understands:

  • The hazardous substances used in cleaning
  • How to handle them safely
  • How to protect themselves, clients, and the environment
  • Their legal responsibilities under UK COSHH regulations

It forms part of Decent Cleaning’s mandatory training and certification pathway.

🧪 2. What Counts as a Hazardous Substance in Cleaning

In our industry, hazardous substances include:

Cleaning Chemicals

  • Multi‑purpose cleaners
  • Descalers
  • Bleach and disinfectants
  • Oven cleaners
  • Floor care chemicals

By‑Products

  • Chemical vapours
  • Aerosols from spraying
  • Dust from vacuuming or agitation

Biological Hazards

  • Mould
  • Bodily fluids
  • Contaminated waste

📋 3. COSHH Risk Assessment (Decent Cleaning Standard)

Every product we use must have a COSHH assessment completed and stored in our central system.

Each assessment includes:

  • Product name & supplier
  • Hazard classification (CLP symbols)
  • Risks to health
  • Required PPE
  • Safe handling instructions
  • First aid measures
  • Spill response
  • Storage requirements

Staff must read and understand the COSHH sheet before using any product.

🛡️ 4. Hierarchy of Controls (Applied to Cleaning Work)

1. Elimination / Substitution

We always choose the least hazardous effective product. Example: Using neutral pH cleaners instead of corrosive alternatives.

2. Engineering Controls

  • Ensure rooms are ventilated
  • Avoid spraying into the air unnecessarily
  • Use dilution systems where provided

3. Administrative Controls

  • Follow Decent Cleaning’s step‑by‑step cleaning procedures
  • Never mix chemicals
  • Only decant chemicals into labelled containers
  • Keep COSHH sheets accessible on site

4. PPE (Last Line of Defence)

  • Nitrile gloves
  • Safety goggles when handling corrosives
  • Masks when using sprays in enclosed spaces
  • Aprons for wet work
